BACKGROUND The goal of the STREETS project is to develop a smart, next generation, traffic management and control system. The STREETS project will use advanced traffic control strategies to enable dynamic traffic routing to maximize the use of existing roadway capacities in the Dubuque metropolitan area. The initial deployment of STREETS covers 33 signalized intersections within the City of Dubuque. The STREETS project seeks to employ Active Transportation and Demand Management (ATDM) strategies which will require a suite of modeling tools and methods that will enable the City of Dubuque to evaluate the potential benefits of implementing ATDM strategies in a dynamic and proactive fashion using both real-time and historic data. The benefits from implementation of STREETS include, but are not limited to: • Reduced wear and tear on major corridors • Reduced congestion • Improved travel times • Improved safety • Reduced emissions • Enhanced system monitoring capabilities The full set of objectives can be found in the STREETS Concept of Operations in the reference section of the RFP. DISCUSSION The Request for Proposals (RFP) process will allow the City to retain a consultant to develop and deploy a Smart Traffic Routing with Efficient & Effective Traffic System (STREETS) that will use traffic control strategies to enable dynamic traffic routing to maximize the use of existing roadway capacities in the Dubuque metro area. The initial deployment of STREETS covers 33 intersections which includes integration of the STREETS software, servers, camera analytics and traffic signal enhancements within the City of Dubuque. STREETS should be scalable to allow full buildout of the city as future phases are added. It is anticipated that the timeframe for the project will be approximately 30 months following the signing of a professional services agreement. This RFP was originally listed on February 26th, 2020 but was delayed due to Covid and will be re- initiated.

The selected consultant will be eXpected to complete the contracted scope of work within the specified timeframe, under the general direction and coordination of the Project Team (Project Manager) as authorized by the overseeing committee established by the Project Team. The City of Dubuque, ECIA, and DMATS are entities established under Iowa law and, as such, they are governed by Iowa and federal laws and regulations. These laws and regulations concern a variety of matters relevant to this project, including but not limited to, open records and open meetings, competitive bidding processes and requirements, contracting, and tort and other immunities. 3. PROJECT BACKGROUND The members of the Proj ect Team partnered together to develop the Smart Traffic Routing with Efficient & Effective Traffic System (STREETS) project. The goal of the STREETS project is to develop a smart, next generation, traffic management and control system. The STREETS project will use advanced traffic control and route management strategies to enable dynamic traffic routing to maximize the use of existing roadway capacities in the Dubuque metropolitan area. The initial deployment of STREETS covers 37 signalized intersections within the City of Dubuque. The STREETS project seeks to employ Active Transportation and Demand Management (ATDM) strategies which will require a suite of modeling tools and methods that will enable the City of Dubuque to evaluate the potential benefits of implementing ATDM strategies in a dynamic and proactive fashion using both real-time and historic data. The benefits from implementation of STREETS include,but are not limited to: • Reduced wear and tear on major corridors • Reduced congestion • Improved travel times • Improved safety • Reduced emissions • Enhanced system monitoring capabilities The full set of objectives can be seen in the STREETS Concept of Operations, given in References. Currently, the City of Dubuque operates all traffic signals and other ITS devices within City limits (including state highways). The current signal system in Dubuque includes 115 traffic signals. Most of the signal controllers are M50 Siemens controllers with EPAC firmware. There are also M60 Siemens controllers located along the US 20 at grade intersections and some other locations. The signal cabinets are NEMA TS- 1 or TS-2. Approximately 80% of the system is connected to a fiber optic communication system which is comprised of a minimum of 24 multi-mode and 48 single-mode fibers. The City currently uses Siemens' TACTICS central management software to communicate with the traffic signal system. The City primarily uses MatriX microwave vehicle detection, with some of the smaller intersections (on Locust Street and US 20) occasionally using inductive loops. The City has 31 Acyclica devices installed throughout the city for calculating travel time and origin/destination,but this number is eXpected to grow. The City has an eXtensive network of CCTV cameras which are both used for traffic surveillance and post-event investigation of the events that affect safety and security of the travelers. The City also constantly record videos from these cameras (24/7 for 30 days)via a Milestone video management system. In addition to the existing ITS devices, the City has undertaken an aggressive program to expand ITS deployment within the City including fiber optic conduit, redundant failover fiber Optic Loops, Dynamic Message Sign (DMS), Smart Sensor, Traffic Camera, and wireless communication. All these will be part of future STREETS and play roles in dynamic traffic routing. The STREETS project intends to deliver an automatic system that gives the City staff ability to monitor traffic operations, and intervene as necessary, but does not require constant or significant manual operations. 7 4. PROJECT PURPOSE The level of service in 2010 is shown in Figure 2 and the 2045 forecasted level of service is shown in Figure 3 for the corridors included in the initial network of STREETS based on the DMATS Travel Demand Model. Based on the Model results, the corridors in the study area are heavily travelled (where most of them are at LOS C or D), among which a few locations on US Highway 20,Asbury Rd,University Ave, and US Highway 151/61 reached LOS E and F in 2010. Most of the project corridors are projected to attain level of service E and F by 2045. The Travel Demand Model also shows the "imbalanced" traffic flow on different corridors within the network. While several corridors are expected to reach LOS F, some corridors show available capacity. This indicates a potential for encouraging traffic rerouting to utilize the "unused" capacity. Such trends of unbalanced traffic loads are even more obvious (and traffic reassignments could be even more beneficial) during non-recurring congestion (i.e., incidents and special events) when certain corridors are heavily congested while the others remain almost under free-flow conditions.

PROJECT OBJECTIVES The purpose of the STREETS is to provide better (and more balanced) utilization of the City of Dubuque's highway network infrastructure. This goal should be achieved through utilization of the existing and new Intelligent Transportation Systems (to be deployed within the STREETS project), which will apply strategies to dynamically address both transportation demand and supply. It is envisioned that deployment of the STREETS will accommodate the following activities. 5.1 Data Collection • Collect O/D data from various sources (i.e., O/D spreadsheet data from IBM that needs further post-processing) • Prioritize usage of the data owned by the City • Collect real-time traffic data • Incorparate signal phasing and timing data • Include roadway geometry data • Ensure that the STREETS is compatible with the existing infrastructure-to-vehicle (I2V) systems to integrate future Connected Automated Vehicle (CAV) data into STREETS (e.g. US 20 has �9 intersections with DSRC road-side units). 9 5.2 Performance Measurement System • Provide travel time measurement system • Explore usage of the 3rd party data(i.e. Waze for incidents, INRIX for speeds) • Determine Traffic State and Trigger STREETS operations • Monitor Real-Time Incidents/Events • Monitor System Assets State • Calculate System Performance Metrics 5.3 Traffic Modeling • Develop Traffic Demand Model to estimate O/D and other data for Micro-simulation Model • Provide Simulation model covering minimum 9 key corridors • Provide Simulation model capable of performing traffic route assignment • Provide Simulation model capable of interacting with DSS • Provide Simulation model capable of replicating signal controller functions 5.4 Decision Support System • Provide a User Interface (UI) for data display and monitoring of traffic operations • Provide a system allowing data management • Generate response plan (Rerouting and Signal Timing) • Evaluate response plan (Rerouting and Signal Timing) • Recommend an optimum and context-sensitive response plan (e.g. no rerouting heavy trucks on minor streets)) 5.5 Signal System • Evaluate/Upgrade local controllers • Evaluate/Upgrade ATMS software • Provide Adaptive Signal Control Technology (ASCT) System • Integrate/use ATSPM data and framework for STREETS operations 5.6 Communication System • Increase speed,bandwidth, and reliability of center-to-field communications • Provide communications among each module of the STREETS • Develop and implement network security protocols • Evaluate future connected vehicle communications system 5.7 Advanced Traveler Information System • Enhance and develop traveler information delivery media(i.e., DMS, 511, Smart Phone App) • Ensure that the messages, for dissemination to travelers, are provided through an open data feed so that they can be used by multiple applications and phone apps • Develop procedures to automate information retrieving and Alarms/Notifications distribution • Disseminate accurate and real-time congestion-related information to travelers 5.8 Operations and Maintenance • Automate STREETS system operation to reduce staff needs • Allow system management • Develop MOU for STREETS maintenance between the City and ECIA • Provide adequate staff training for the City, ECIA, and other stakeholders It is eXpected that, based on previously established STREETS goals and objectives, following performance measures (shown in Table 1) will be used to evaluate success of the STREETS system operations. 10 Table 1 —Performance Measures to Evaluate Success of STREETS GOALS PERFORMANCE MEASURES • Average travel time per trip for the network and each corridor • Average delay per trip (for the network and each corridor) • Travel time reliability measures o Travel time index (ratio of peak period to free-flow travel times) o Buffer indeX: extra time needed to be on-time 95% of the time Improve person and vehicle throu hgLputs Mobility � • Vehicle-hours traveled • # of rerouting events • # of automatic signal retiming events due to the STREETS system • Other innovative performance measures which may be able to document balanced utilization of various corridors in the network • Other existing and new ATSPMs • Intersection LOS Reduce • Freeway LOS Congestion • Arterial LOS • Volume/Capacity Ratios • Incident rate Improve o # of Secondary Accidents Safety • Accident rate o Injury o Fatality • # of events disseminated (i.e., travel time information) o Per O/D pair o Construction Information o Incident for Travelers o Special Event • System Availability o Device up-time • S ll Usage o Number of Subscribers 6. PROJECT SCOPE OF SERVICES The STREETS includes the following major components: 1) Travel Demand Model (TDM); 2) Microsimulation Traffic Model (MTM); 3) Adaptive Signal Control Technology (ASCT); 4) Decision Support System (DSS). The STREETS will also interface with other components include, but not limited to, Advanced Traffic Management System (ATMS), Advanced Traveler Information System (ATIS), and third- party data source (i.e., Waze, INRIX). The TDM will be utilized to estimate the origin/destination (O/D) and other necessary data for the microsimulation traffic modeL The MTM is to represent the current roadway network and be capable of executing traffic assignment(dynamic traffic routing)based on estimated/measured traffic impedances of the network links. The ASCT will develop optimized signal timings, in real-time, after changes of traffic conditions are determined by STREETS. The DSS is to function as a core model which communicates with TDM, MTM, ASCT and other components, provide data exchange, dynamic routing strategy generation and integrate all components into a complete STREETS. The interaction of these components is illustrated in Figure 4. 11 Figure 4 - A conceptual framework of STREETS Trigger Input Field Data Performance Measurement • Tra#fi�Count • Tra�el Time • 5peed Data • Traffic flow � �_fl • Traffic Pattern • 5igna!Phasing • Inc9dent �� ■ 5igna!Timing • System PerFormance , Pracess � Demand Model� Micro-simulation Model Deci�ion I Decision Support System • Route Re�ommendation • Timing Recommendation Action ATIS ATMS/ASCT • ❑�ns • Apps Adaptive 5ignal Timing • 511 L. The Selected Vendor shall design, develop, integrate, and deploy the STREETS which includes the main components and processes as depicted in Figure 1. The major components of such a system should be: 1) Travel Demand Model (TDM); 2) Microsimulation Traffic Model (MTM); 3) Adaptive Signal Control Technology (ASCT); and 4) Decision Support System (DSS). 12 The STREETS will also interface with other data and performance-measurement platforms. These could include Advanced Traffic Management System (ATMS), Advanced Traveler Information System (ATIS), and third-party data sources. It is important to note that the ECIA's TDM will provide estimated O/D tables and other necessary data for traffic models. The MTM is to represent the current roadway network and be capable of executing traffic assignment (dynamic traffic routing)based on estimatedlmeasured traffic impedances of the network links. The existing systems and real-time traffic characteristics are expected to come from multiple sources: City-owned field data (CCTV cameras, Acyclica, other sensors), and INRIX Travel-Time data. The ASCT will develop optimized signal timing in real time after changes of traffic conditions are determined by STREETS. The DSS is to function as a core model which: communicates with TDM,MTM,ASCT and other components;provides data exchange; generates dynamic routing strategies; and integrates all components into the STREETS. Built on the eXisting and future ITS elements, implementation of the STREETS may rely on some of the City's investments in ITS infrastructure — e.g., data collection and performance measurement systems, processing and dissemination systems,control algorithms,and an upgraded traffic signal system. The Selected Vendor is required to communicate with the Project Team to get a proper survey of the existing and future ITS infrastructure. Then, the Selected Vendor will identify any potential gaps in the existing or planned infrastructure(for a successful deployment of their proposed STREETS system)and will integrate acquisition and deployment of such missing infrastructural components as part of this contract. Prospective bidders will be required to provide unit costs (e.g. per unit, linear foot) in their proposal which will be included in the negotiated contract. In the case that the STREETS system proposed by the Selected Vendor requires the installation or modification of construction elements, such as additional ITS equipment, field infrastructure devices and/or communication media (wiring, switches, etc.), and similar, a contract addendum will be executed once the scope is determined identifying the total cost of the infrastructure work. To ensure seamless and efficient functioning of the STREETS potential vendors shall develop their proposal with a goal for STREETS to deliver: • A high-speed, reliable communications system. • A highly accurate,reliable detection system. • Improved traffic signal controllers. • High-speed and reliable servers and databases. • An automated process to transfer data. • An automated process to analyze traffic conditions. • Automated, and highly accurate, means to communicate traffic conditions to the traveling public. 7. SYSTEM DESIGN The selected Vendor shall design STREETS in such a way to ensure efficient and seamless operations and integrations of following system modules: 7.1 Data Input This module defines the data needs for STREETS system. It gathers data from various data sources, compiles them, and feeds the data into Micro-Simulation Model. O/D data can be collected from traditional surveys and smart phones as we1L The O/D data, traffic counts for both roadway segment and intersection turning movements, signal timing data, roadway improvement (i.e., adding a travel lane) are fed into Micro- Simulation Model to simulate existing roadway netwark operation and used to conduct evaluation for various 13 operation scenarios such as normal daily operation, incident,planned or unplanned events. Special attention should be given to a variety of video feeds and similar eXistin�data and their potential use for STREETS applications. It is expected that existing video feeds will be used both as the main system inputs and data to validate inputs and performance measures based on the other data sources. Envisioned Deliverables for 7.1 —A report detailing (in a list format or similar) all of the data inputs that are fed into the STREETS, classifying the data based on their type, source, spatial and temporal levels of aggregation,intended use(s), and similar. The report should be appended with examples of various data inputs in the STREETS, in their raw textual format. 7.2 Performance Measurement The module includes use of various field devices, and/or third-party applications (i.e. Waze, INRIX, Google) that can provide real-time data to represent traffic operations and system's performance. Firstly, this module is to constantly monitor traffic operations within the roadway network and detect any changes in traffic patterns or capacity reduction that causes unbalanced traffic assignments within the network. The field devices for traffic monitoring include CCTVs for traffic surveillance, travel time and delay evaluation system (i.e. Acyclica), and other selected technologies during the system design. This module is supposed to provide user with hourly traffic counts including peak turning movement counts at each intersection. A report showing how these differ from the daily average numbers for that time period would be very useful. This module shall also contain a defined process to detect, identify, and verify incidents, and a methodology to identify potential unbalanced traffic assignment within the network(i.e., significant variation in travel time/delay for a roadway segment or unusual disparity in travel time/delay among roadways). This module can also utilize third party applications to retrieve existing information such as verified incidents, lane closures, and delays; and feed these data into the STREETS to trigger traffic reassignment evaluation. For example, STREETS may eXchange data with Waze Connected Citizens Program (CCP) to receive real-time incident information to trigger route reassignment, and use Waze to inform drivers of major events and other roadway insights such as detouring through the app. Secondly, this module is to interact with the DSS module to provide system performance data for system reporting. Performance data such as travel times, delays, and incident clearances should be exported to STREETS. These data can be retrieved in various reports over time to indicate effectiveness of STREETS and potential for future system enhancements. Envisioned Deliverables for 72—1. A suite of software and hardware components developed and established to measure and report performance of the traffic conditions relevant for the STREETS. 2.A report containing description of the hardware (e.g. field devices) and software used to measure performance of the STREETS. This report should also describe all processes and methods used to identify and verify events/incidents and unbalanced traffic assignment in the network. The report essentially needs to explain to the user how the STREETS recognizes that traffic flows on the relevant routes are not balanced and the performance measures and methods which are used to detect and verify such conditions. The report should be supported with outcomes (e.g. screenshots)from the STREETS visual aids to ensure that the report truly represent STREETS operations. This report should also document connections with all of the other STREETS modules (e.g. DSS module). 7.3 Traffic Modeling The module defines the process of STREETS system. The STREETS system requires both Travel Demand Modeling (TDM) and Micro-simulation model to mimic the roadway network to be included in the system. 7.3.1 Travel Demand Modeling The module contains an existing or modified regional TDM. The model provides highway passenger car and truck origin-destination trip matrices needed in development of the Micro-simulation model. The regional model highway network is used as basis for developing the Micro-simulation network. 14 7.3.2 Micro/meso simulation Modeling STREETS requires the development of a micro/meso-simulation traffic model of the Dubuque metro area (including all relevant roads and all signalized intersections) to represent existing traffic conditions. The model will be capable of replicating signal operations from the field and it will produce truthful outputs of the field traffic conditions(travel times,delays, etc.)so that following traffic assignments/routing can be executed based on verified data. The model will execute traffic assignments (reroute vehicles) based on the estimated/measured traffic impedances of the network links when changes in traffic patterns, or traffic states, are identified. Prior to the integration in the STREETS system, the model will be calibrated and validated to confirm that field data (e.g. travel times between signalized intersections, intersection approach delays, average phase times) are matched properly. Under STREETS operations, a traffic status change or capacity change (i.e., verified incident, planned special events, construction actives, etc.) will trigger the running of this model. This model is utilized to run and test re-routing alternatives and validate the proposed detour routes based on the field conditions (e.g., major road work or lane closures; test the same scenario in the model and confirm that the assignment can reflect conditions observed in the field). The modeling results include traffic detour represented by (rapidly) simulated traffic flows on selected corridors after traffic reassignment within the network. Then the model will feed the information into the DSS module. Envisioned Deliverables for 7.3—1. STREETS' micro/meso model,which should be delivered as a standalone application that can be observed within STREETS operations showing at any time modeled traffic conditions and the differences between modeled and field values for a number of the selected performance measures. The last part does not have to be integrated into the micro/meso model interface itself, but it should be accessible within the STREETS. 2. A report eXplaining modeling process and connections and interfaces between existing ECIA Travel Demand Model and a micro/meso simulation model developed within the STREETS. 7.4 Decision Support System (DSS) The DSS is a core module of the STREETS system which integrates other modules and contains other novel functionalities. This module interacts with many other modules, allows data exchange, handles data formatting/processing, detects congestion, recommends rerouting strategies, and receives feedback from the other modules. Figure 5 presents the data flow to/from DSS to all other modules of the STREETS system. The DSS provides the following functionalities in the STREETS system: • Interface the user for STREETS operation with displayed inputs and outputs and allow manual intervention, as necessary • Gather, categorize, format, and compile input data from other modules • Handle erroneous and missing data • Store and maintain a library of pre-defined timing constraints under a variety of traffic flows • Allows special events scheduled in STREETS system to trigger new timing plan assignment • Receive, evaluate, and recommend rerouting strategy developed by Simulation Model • Interface with ASCT to request timing changes and receive feedback • Interface with ATIS to request dissemination of traveling information such as alternative route(s) • Interface with Performance Measures System to validate system performance • Conduct system performance reporting 15 Envisioned Deliverables for 7.4—1. A suite of software and hardware components developed and established to provide functionalities of the DSS module. 2. A report containing description of how functionalities from the list above are achieved and executed. The report should show and explain conceptual methods and interfaces between various STREETS' modules reinforced with a number of screenshots and other visual aids (and other system outputs) to prove STREETS' ability to perform listed functionalities. 7.5 Advanced Traveler Information System (ATIS) ATIS is an essential component of the STREETS system.ATIS provides the users of the transportation system with real-time information that could be used to make decisions about route choices, estimate travel times, and to avoid congestion. Existing and proposed DMS,a traffic website(i.e. 511)and a smart phone application are envisioned to provide this data to the users. • Dynamic Message Signs (DMS) — DMS provides en-route information to drivers regarding traffic and roadway conditions such a travel time and recommended alternative routes. • Smart Phone App —A free smart phone App for STREETS operation is to be included in STREETS to provide alternative route information and verify motarist's adoption of suggested route. • 511 — Existing or enhanced 511 system is used for dissemination of travel time and traffic route recommendation by STREETS. • Future in-car Information dissemination system • Consider use of The Road-Side Units (RSUs) (installed along US 20) and DSRCs to provide drivers with relevant information as they pass key points along the intersection. Perhaps such messages could be dynamic,reflecting changed traffic conditions. Envisioned Deliverables for 7.5 — 1. Software interfaces between STREETS and other relevant software and hardware components necessary for dissemination of the necessary information to the travelers. This deliverable should include any smartphone apps developed to disseminate relevant STREETS information to the travelers. 2. A report documenting how STREETS interacts with relevant dissemination modules (e.g. DMS, 511) supported by several visual aids to document STREETS interfaces and information dissemination. 7.6 Adaptive Signal Control Technology (ASCT) The STREETS contains an ASCT system to dynamically change signal timings based on observed and predicted congestion as estimated by the Micro Simulation Model. The ASCT is expected to be fed by DSS with recommended timings, which is an action triggered after optimal traf�c flows are determined through a traffic assignment procedure. The ASCT then takes control and utilizes it is own adaptive algorithm to adjust signal timings in a partial and progressive fashion while confirming that the proposed routing changes are implemented in the field. Most of the existing ASCT systems require eXtensive vehicular detection. The ASCT deployed under STREETS shall work with both field detection data and data fed by DSS. The proposed ASCT must be integrated in the STREETS properly to enable signal timing changes to be made in real-time without creating disruptions to the field operations. The ASCT shall also have a Software-in-the-Loop (SIL) capability which is compatible with the field traffic controllers. Changes made in the SIL database of the ASCT need to be seamlessly transferrable to the field controllers. The ASCT shall also contain a feedback loop which suggests signal timing changes. The adopted ASCT should only fully implement signal timings change, for optimal traffic rerouting, after the assurance from the field that the drivers are adopting/following on the suggested routing strategy. In the case that the STREETS is malfunctioning(e.�., DSS not feeding data to ASCT), the ASCT shall still work as an inde�endent system to adjust si�nal timin�s for the deploved network. 16 It should be noted here that some of the intersections within the City of Dubuque will be equipped with Automated Traffic Signal Performance Measures(ATSPM)which is a system that could be used in functional coardination with the intended ASCT. Actually, several signal technology vendors already developed ASCTs which interface well with the ATSPMs and thus this option could be explored when deciding how to integrate signal performance measures, and necessary signal modifications, into the STREETS. Envisioned Deliverables for 7.6—1. A functional ASCT system, either commercial of-the-shelf or developed for the purpose of this project. If the latter option is used extra efforts are eXpected to prove validity and quality of the ASCT operations. It should be specifically documented that operations of the ASCT are accounted by the micro/meso model so that the DSS module can base decisions on relevant interaction between route-choice and dynamic traffic signal timings, as occurring in the field and mimicked in the simulation model. 2.A report containing description of the hardware (e.g. field devices) and software used to provide ASCT functionalities within the STREETS. This report should describe all fundamental processes used by the ASCT but also supported by visual aids from ASCT/STREETS documenting realization of the intended methods and processes. 7.7 STREETS Logical Process The STREETS project intends to deliver an automatic system that gives the City staff the ability to monitor traffic operations and intervene, as necessary, but does not require constant or significant manual operations. Ideally, if no significant traffic disturbance events occur, STREETS will run 24/7 without requiring operators to interfere manually with traffic operations. The system shall use CCTV videos with analytical capability, or other performance measurement systems, to automatically capture traffic change and trigger STREETS process. The project will reduce equipment costs at individual intersections by providing signal timings through a centralized Adaptive (Dynamic) Control Traffic System. The project will help the MPO measure the performance of the system by providing 24/7 traffic volumes, turning movement counts, and delays at all major corridors and intersections. Figure 5 describes the logical process of the proposed STREETS system. Envisioned Deliverables for 7.7—A report describing logical connections between various subsystems of the STREETS. Figure 5 is only a high-level proposal of how the system should work. The vendors are given freedom to modify the proposed concept with a strong justification and explanation why an alternative logical process would be superior. Deliverable for this task should contain description of such accomplished logical process. This deliverable, similar to many others, should be supported by concrete proofs of logical correlations between STREETS' components. 8. SYSTEM INTEGRATION The scope of the System Integration effort includes all application systems, online services, interfaces, and data exchanges that are envisioned to be part of the STREETS. The strategy for system integration will be to remediate, develop, and perform all testing of services that will be needed for integration of all of the STREETS components into a functional,reliable, and a user-friendly system. Wherever possible, the System Integration services will be proactively designed, constructed, and tested prior to final integration with the STREETS. A Selected Vendor is responsible for deliverables of all system remediation and services associated with applications, interfaces, and data exchanges that must be integrated within the STREETS (as shown generally in Figure 5). Figure 5 loosely depicts an expected way on integrating STREETS system components and processes into a fully operational and meaningful system, which will be able to achieve mentioned objectives. The Selected Vendor is allowed a freedom to deviate from the proposed concept if such deviations can be properly justified and required outcomes delivered. 17 Figure 5— STREETS System Process MoniiorTraffic � J ILegend .-'.- ..'-.. �a Not{vng �—No Traflic 3catus Change � � Fieid Data Performance � I� Measurement .� � Nlodeling ATMS�ASLT � Yes Run Qemand Model � � ❑55 ATI S Run Mivo-Sirnula3ion and Generate MOE Field Data I • Traffic Data � i �• ■ Signal Timing ' 6o Nothing �a#�—No-4 ��Rerouting Imprwes �•� Network?

SYSTEM VALIDATION (RESPONDING TO OPERATIONAL SCENARIOS) This section presents a number of operational scenarios that are intended to capture activities associated with operations of the system. The objective of developing operational scenarios is to capture potential and most frequent user needs. The operational scenarios capture both routinely and non-routinely performed activities. Thus, it is important that the operational scenarios are realistic and reasonable. 18 The operational scenarios include the following: • Scenario 1: Traffic Monitoring & Operations - Recurrent Congestion • Scenario 2: Traffic Monitoring & Operations - Unplanned Event • Scenario 3: Traffic Monitoring & Operations - Planned Event • Scenario 4: Traffic Monitoring & Operations - Maintenance All of the listed scenarios are detailed below for the proposed system. The Micro-simulation Model should be calibrated and ready for use,prior to the testing/applying of any operational scenarios. 9.1 Scenario 1: Traffic Monitoring & Operations - Recurrent Congestion Recurrent congestion represents a normal day-to-day operational scenario. Under this scenario, each corridor eXperiences its daily traffic variation depending on time of day; there is no drastic disparity in congestion levels among the corridors, and traffic flows are assumed to be naturally assigned within the network based on impedance perceived by travelers. The ASCT shall be well calibrated based on the traffic characteristic of each corridor and function independently per corridor to adaptively optimize signal timings based on traffic variations. The performance measurement module constantly monitors traffic, however, no drastic traffic changes (over historical patterns) are observed and performance data are archived by the individual components (i.e., Acyclica, CCTV data storage). The outputs from the performance measurement module should be able to document seasonal and weather variations, preempt interruptions, and similar recurring events. 9.2 Scenario 2: Traffic Monitoring & Operations - Unplanned Event This scenario represents a typical STREET operation when traffic re-routing is needed. Under this scenario, the performance measurement model constantly monitors traffic status; an unplanned event,typically a crash, is reported either by the third party system, or by established incident detection algorithm (i.e. unusual travel time or delay). This triggers STREETS to run Micro-simulation Model to estimate the impact of this event. Event location (i.e., mile post of the corridor) and severity (i.e., # of lane closure) is verified via CCTV cameras, and relevant inputs are entered in the simulation model. The model run is performed to reassign the traffic among the corridors on the roadway network. This results in simulated performance measurements and a new set of traffic flows on affected corridors. The simulated traffic flow data are fed into the DSS module. The DSS compares the simulated traffic flows and field traffic flows,with a set of predetermined criteria, and suggests new timings for each intersection on the impacted corridors.Presumably the intersections on corridar where the event occurs will receive `more relaxed' signal timings whereas those on corridors where traffic is reassigned will receive `more restrictive' signal timings. Before sending these suggested timings to the ASCT system, the DSS will also examine other conditions such as truck routes, school zones which may restrict or limit the deployment of new timings, etc. Once approved,the new timings are forwarded to the ASCT system, which may (or may not) further adjust the timings before field implementation. At the same time, the DSS disseminates the recommended route information to the ATIS module such as DMS, 511 and mobile apps to inform the motorist and encourage detour. The ASCT finalizes recommended timings (including the feedback from the streets, on the actual traffic rerouting) and deploys the timings in the field. Then, it continues to operate based on its own adaptive algorithm to adjust timings based on varying traffic flows. 9.3 Scenario 3: Traffic Monitoring & Operations - Planned Event This scenario represents another typical STREET operations case (e.g. road reconstruction, a bridge closure) when traffic reassignment is needed. Under this scenario, a planned event such as a game,is scheduled ahead. 19 The city staff shall use historical data to estimate the impact of the scheduled event and new O/D trip patterns for use in Micro-simulation Model to predict the increased traffic demand on the roadway network. Prior to the planned event, STREETS runs Micro- Simulation Model with recommended O/D pairs, and predicts traffic flows based on the field data while the performance measurement module constantly monitors traffic state. The simulation model then feeds the simulated traffic flow data into the DSS module. The DSS compares the simulated traffic flows and the field traffic flows, based on a set of predetermined criteria, and then selects new signal timings for each intersection within the impacted corridors. Similarly,to the previous case,the intersections on corridor where the planned event occurs will receive `more relaxed' signal timings, whereas those on corridors where traffic is reassigned will receive timings modified to accommodate extra traffic. Before sending these timings to the ASCT system, the DSS will also examine other conditions such as truck traffic on the routes, school zones and other conditions which may restrict or limit the deployment of new signal timings. Once approved, the new timings will be forwarded to the ASCT system, which may(or may not) further adjust the timings before field implementation. At the same time, the DSS disseminates the recommended route and special event information to the ATIS module such as DMS, 511, and mobile apps to inform the motorists. The ASCT finalizes recommended timings (including the feedback from the streets, on the actual traffic rerouting) and deploys the timings in the field. Then, it continues to operate based on its own adaptive algorithm to adjust timings based on varying traffic flows. 9.4 Scenario 4: Traffic Monitoring & Operations - Maintenance This scenario represents another typical case of STREET operations when reassignment of traffic flows is needed. Maintenance can be scheduled as a routine (preventive) maintenance or as an emergency maintenance. For a routine maintenance, a series of activities should be pre-evaluated using Micro-simulation model such as: duration of the maintenance, number of lanes blocked, and scheduled Maintenance of Traffic (MOT) plans. The results should be a set of traffic flow variations. Prior to the scheduled maintenance, STREETS runs Micro-simulation model based on the field data to verify pre-evaluation conditions. Then it feeds the simulated traffic flows into the DSS module. The DSS then receives the new traffic flows, generates a response plan, alerts the ASCT to modify signal timings, and prompts ATIS to disseminate information about the event and recommended routes. The routine maintenance shall be scheduled within the DSS. Once the maintenance activity is completed and verified, the City staff shall command the STREETS to end the maintenance scenario and resume normal operations. The STREETS will utilize performance data and CCTV videos to verify the recovery of traffic state before commanding the system to a"normal" operation scenario. For an emergency maintenance, STREETS treats the traffic conditions in the same manner as for an unplanned event. Under this scenario, STREET triggers Micro-simulation Model to predict the increased traffic demand on the roadway network. After verifying with the field data,it feeds the DSS module with the simulated traffic flows. Then, the DSS compares the simulated and the field traffic flows, based on a set of predetermined criteria, and it selects new timings for each intersection along the impacted corridors. Before sending these plans to the ASCT system, the DSS will also eXamine other conditions such as truck traffic on the routes, school zones and other conditions which may restrict or limit the deployment of new signal timings. Once approved, the new timings are forwarded to the ASCT system, which may (or may not) further adjust the timings before field implementation. At the same time, the DSS disseminates the recommended route and special event information to the ATIS module such as DMS, 511, and mobile apps to inform the motorists. The ASCT finalizes recommended timings (including the feedback from the streets, on the actual traffic rerouting) and deploys the timings in the field. Then, it continues to operate based on its own adaptive algorithm to adjust timings based on varying traffic flows. Once the maintenance activity is completed and verified, the City staff shall command STREETS to end the maintenance scenario and resume normal operations. STREETS will utilize performance data and CCTV videos to verify the recovery of traffic state before commanding the system to a"normal" operation scenario. 20 9.5 Acceptance Testing This section identifies specific verification reviews and acceptance testing (which could happen `at will') for the STREETS deployment. The acceptance test is expected to include multiple reviews and will include one or more of the following elements: • Demonstration of integration of the STREETS' different software modules • Demonstration of automated data(volume, SPaT) input to the Micro-Simulation Model • Demonstration of data retrieval (volume, SPaT) automatically from the Micro-Simulation Model • Demonstration of Traffic Demand Modeling data(O-D) output • Demonstration of the Micro-Simulation Model's data and output accuracy • Demonstration of Performance Measurement System's data outputs, including peak and turning movement counts by time of the day • Demonstration of transmitting SPaT data to the Decision Support System (DSS) • Demonstrations of the Decision Support System (DSS) • Demonstration of the Advanced Traveler Information System(ATIS),including dynamic messaging from RSUs • Field demonstrations of detection system's data accuracy • Demonstration of City's existing Video Data Analytics system's data accuracy • Demonstration of the STREETS system's full functionalities on hand-held devices (smart phone, tablet etc.) for the STREETS system operator • Demonstration of the STREETS system's full functionalities on hand-held devices (smart phone, tablet etc.) for traveler • Demonstration of the eXisting City owned travel time system (Acyclica) data accuracy • Demonstration of archiving data (volume, SPaT) sent to the Microsimulation Model on both local and cloud-based storage • Demonstration of archiving data (volume, SPaT) output from the Microsimulation Model on both local and cloud-based storage • Demonstration of STREETS graphic summary screen showing all of the inputs and outputs at work • Demonstration of ability to sharing general traffic information with public and developers • Monitoring queue management at user-specified locations • TOC test of communications • Remote monitoring and control of the ASCT and other components of the STREETS • Review of training materials The verification and acceptance testing will be accomplished at approved City of Dubuque locations and at specific field locations within the City. All acceptance test procedures shall conform to the approved acceptance test plans. These tests will be completed and documented by the System Vendors and supervised by the City of Dubuque Project Manager. Operational documentation of the field components is expected to 21 be completed with a laptop, internet connection, and associated cabling. The System Vendors will need to provide multiple staff in the field and at the TOC to document acceptance of certain tests. A verification test case is a logical grouping of functions and performance criteria that are to be verified together.

NATIONAL ENVIRONMENTAL POLICY ACT COMPLIANCE In compliance with the National Environmental Policy Act (NEPA), Environmental Concurrence for the initial phase of this project has already been acquired. However, depending on the STREETS system selected, the vendor may be required to implement upgrades or installation of additional ITS equipment and material such as communication enhancements, signal enhancements, advanced detection, etc. The Selected Vendor will be obligated to prepare environmental reports and documentation including but not limited to a concept statement, determination of effect for threatened and endangered species, archaeological investigations, etc., as applicable, and submit them to Iowa DOT for review on the city's behalf to acquire environmental concurrence for this construction work. As a consequence, the Selected Vendor should plan to allow ample time for this process to be completed between the identification of the improvements needed and the approval for construction to proceed. Based on experience in the city of Dubuque, this may take anywhere from a few weeks to six months from submittal of documentation to approval to proceed. This delay will need to be integrated into the project timeline. 17.
