HDR ONE COMPANY m ~ Many Solutions'" (1 1 To: Steve Brown, The City of Dubuque From: Will Sharp, PE, Tara Kramer, PE, Courtney Sokol, PE, Project: East-West Corridor Connectivity Study Mike Forsberg, EI, Anne Peterson, RLA cc: Date: November 3, 2008 DRAFT Job No: gg080 RE: East-West Corridor Study: ECIA model review and screening analysis Introduction The purpose of this memorandum is to document: • Data collection efforts along four primary corridors • An overview of the travel time runs performed for the initial study corridors (includes four primary corridors as well as additional corridors) • The 2031 travel demand model review for the Dubuque metropolitan area • The findings of 18 capacity improvement scenarios ran in the 2031 travel demand model to be used to identify the corridors and improvements to be studied in further detail • Complete street considerations to be incorporated into the corridor improvements Data Collection Information was gathered along Asbury Road, Pennsylvania Avenue, Loras Boulevard and University Avenue to determine possible corridor improvements. This information included existing speed limits, typical cross section and locations of on-street parking and sidewalks. The data collected is summarized in Figure 1. Travel Time Run Summary Travel time runs were performed for the study corridors. Each corridor was traversed at least three times in each direction during the morning and afternoon peak hours. Information gathered included east/west travel time between major intersections, stop duration and observed queues on all approaches. Queues were reported as the maximum lane-queue observed, not the total number of vehicles queued on a multiple lane approach. Additionally, a delay was reported if the average speed between intersections was less than 15 miles per hour. A summary of the travel time runs for each corridor is provided below. The summary was developed to help identify bottleneck areas, thus only possible bottlenecks/capacity issues were identified. I should be noted that delays were experienced at the NW Arterial intersections, but were not noted in the summary below since analysis of the NW Arterial intersections are not included in this study.

Major projects included in this 2031 LRTP (Base) model include: SW Arterial. This facility is coded as four-lane, 55 mph with daily directional capacities of 17,720 (4 lane divided, minimal side friction, with left turn lanes). North Cascade. The speed on this facility was reduced to reflect residential development in the area and numerous access points along the southern portions of this corridor (Southwest Arterial to Cedar Cross). It is coded as 10 mph in the year 2031 on the southern portion, as directed by the City of Dubuque. The speed on this section of N. Cascade is coded at 35 mph in the 2005 model. Daily directional capacity is 6,030 (2-lane undivided, minimal side friction, without turn lanes). Grandview Extension. The extension of Grandview Ave from W. 32nd Street to the NW Arterial is included in the 2031 LRTP travel demand model. The extension is coded as 35 mph with a daily directional capacity of 7,005 (2-lane undivided). The base 2031 assignment on the Grandview extension, just south of the NW Arterial, is approximately 15,000, which is at daily capacity. By comparison, JFK Road just south of the Northwest arterial assignment is approximately 5,000, which is well under its daily capacity of 15,300. The Grandview extension provides a major travel path in the 2031 model: from the area north of the NW Arterial/ JFK/ Plaza Drive ~ NW Arterial -~ Grandview Ave ~ 32nd Street ~ US-52. NW Arterial. Same as existing: coded speed at 50 mph +/- 5 mph. Daily directional capacity is 17,720 (4 lane divided, minimal side friction, with left turn lanes). Reviewed the volume to capacity ratios of the 2031 LRTP model assignments. Capacities reflect a Level of Service (LOS) D. Therefore, a V/C of 1.0 represents the LOS D threshold, V/C of 1.1 represents LOS E threshold. By inspection, the corridors with V/C above 1.0 include Asbury Road, US-20, Grandview Ave, Cedar Cross Road, Loras Blvd, and Pennsylvania. Avenue. Along Asbury Road, the 2031 V/C ratio changes from 0.84 to 1.0 at Spring Green Drive. Verified that Pennsylvania Avenue is coded as 3-lane roadway, reflecting the recent conversion from 4-lane to 3-lane adjacent to Hempstead High School. The daily directional capacity is 6,995 (2 lane undivided, heavy side friction). Refer to Figure 2 for a summary of the existing traffic volumes and capacities. Refer to Figure 3 for a summary of the 2031 projected traffic volumes and capacities. Corridor Improvement Scenarios Below are 18 corridor improvement scenarios that were run in the 2031 travel demand model by HDR in October 2008. These corridor improvement scenarios were developed by HDR and approved by the City of Dubuque. The purpose of running these scenarios was to help identify which capacity improvements should be studied in further detail in the next phase of the East West Corridor Connectivity Study. The corridor improvements including coding modifications necessary to replicate the corridor improvements as well as the results are summarized for each scenario. It should be noted that similar capacities were used for 2-lane undivided with left-turn lanes and 3-lane corridors, thus more capacity may be realized fora 3-lane cross section given the high number of driveways along the study corridors. Figures 4 - 21 summarize the resulting volume differences and capacities of the Scenarios 1 -18 corridor improvements, respectively.

This philosophy stresses the provision of safe access for motorists, pedestrians, bicyclists and transit users. Besides safety, other improvements to the visual and physical environment of the roadway can provide additional health and economic benefits to users. Current use may not reflect the true potential for alternative transportation use because of lack of opportunity. Local land use, such as schools, parks, shopping areas, medical centers, etc. need to be considered in examining the user character with the study corridors. Although it may not be a consideration within the scope limits of this study, access between local land uses and neighborhoods and access to the main east/west routes is an important factor in the eventual improvement of east/west connectivity. The needs of motorists, pedestrians, bicyclists and transit users may sometimes conflict, so the benefit to each user needs to be weighed within the context and constraints of each corridor. For safe and efficient travel, motorists desire minimal travel delays, minimal visual and physical conflicts or distractions and consistency in design. If walking is to be encouraged, pedestrians need more than a simple sidewalk and safe crossings to feel secure and comfortable. Protection from climate, buffering from motorists, an aesthetically pleasing environment, and access for the disabled are some of the issues to be considered. Bicyclists want a connected network of facilities that are safe and direct, they want to avoid stoppages, and they need their visibility to other roadway users improved. Transit users are defined not only by the riders, but also the drivers. Transit operators need space to operate, minimal delays to keep on schedule, and minimal conflicts with other roadway users or facilities. Riders desire accessible, comfortable and secure waiting areas placed along awell-connected network. As different scenarios are examined in this study to improve motorist connectivity, the following design elements need to also be considered. Available right-of-way will be a factor in determining how the strategies and opportunities discussed below fit with each scenario. Street Design Long, straight, wide streets encourage motorists' speed, which has an impact on the safety of all roadway users. Shorter distances between blocks encourage more vehicle stops and also provide more pedestrian access points for crossing, which in turn results in less jaywalking. Narrower streets encourage slower motorists' speeds and provide shorter widths for pedestrian crossing. Traffic calming strategies, such as mid- block bulbouts, center medians, reduced turning radii, etc. which benefit the pedestrian also need to be weighed with the needs and safety of bicyclists, and operability of transit vehicles. Dedicated bus lanes increase access and visibility for those users. For bus transit, the use of bulbouts and turnouts need to be evaluated for effectiveness. Turnouts should occur at the far side of a signal so a bus does not get delayed waiting to re-enter traffic. Bulbouts allow more room for riders waiting to access transit and can reduce delay motorists waiting behind the transit vehicle. Intersection Design Crossing features such as medians, bulbouts, pavement markings, distinct pavement types and pedestrian and bicycle signalization help to regulate different travel modes as well as increase visibility. On-demand signalization dedicated to pedestrians and bicyclists gives some additional control to those users for crossing. Medians and bulbouts provide pedestrians with additional landing areas while crossing and more space along roadway edges. Distinct paving types and pavement markings increase awareness from other motorists that this crossing space is dedicated to pedestrians or bicyclists. It can also reflect character of a neighborhood or region, which may subtly play into wayfinding strategies. Roundabouts allow vehicles and bicyclists to HDR Engineering, InC. 8404 Indian Hills Drive I Phone (402) 399-4997 Page 8 of 9 Omaha, NE 68114-4098 Fax (402) 392-6914 www.hdrinc.com continue moving through the intersection, at reduced speeds, while providing shorter crossing distances for pedestrians. They also provide opportunities for more visual interest and identifying neighborhood character. Sidewalks Sidewalks are often seen as optional or omitted due to current land use needs. When evaluating the scenarios, the land uses beyond the limited study corridors need to be considered, such as schools, parks, shopping, etc, as those are destinations from neighborhoods. Orientation and alignment are important considerations so that the walk provides an access between destinations. Pedestrians, and in some cases bicyclists, are more exposed to the environment as the users of sidewalks. This makes them more aware of the effects of sidewalk design elements such as location, width, utility interferences, shading, plantings, and the presence of amenities. A narrow sidewalk abutting the curb not only gets diminished by sharing space with utility poles, but makes the user feel less secure because there is no buffer from traffic. Conversely, a planting strip with room for trees provides buffering and shade, but require more right-of-way and may interfere with utilities. Pedestrian comfort is increased if they are buffered from passing vehicles. Some of the elements that serve as buffers include planting strips and landscaping, bicycle lanes, and on-street parking. Walking can be encouraged if the perceived distance can be minimized. Some ways to shorten a perceived distance is to create direct connections between land uses, provide mid-block crossings, and offer amenities along the way, such as benches, landscaping, defined paving, shelters and other resting area type design features. These amenities are also important design elements for transit stops. Rest areas' functions can be shared between users. The addition of water coolers and bike racks within rest areas along key points provides full service for the bicyclists. Lighting Lighting is a key element affecting roadway users' perception and safety. Motorists need better sight distances for safety, so higher levels of lighting provide better visibility. From a pedestrian level, the vehicular lighting level may not serve as well to provide the security that lower height lighting could achieve. Pedestrian scale lighting is spaced closer together and adds a higher lighting level for the user. The use of distinct poles provides an opportunity to identify a neighborhood or district. Another important pedestrian scaled lighting area is transit stop locations. Sustainable Design Opportunities Some of the strategies advocated by the complete streets philosophy, such as separation of walks and adding planting strips also provide the opportunity for additional sustainable design functions. A planting strip can also be utilized as a rain garden since it is adjacent to the curb. Runoff can be directed into these areas to be filtrated before being released which results in improved water quality and reduced velocities. Trees planted in this strip provide shade for pedestrians, bicyclists and parked cars, which results in reducing the heat island effect. Sidewalks can be constructed of porous pavements, which also reduce runoff and helps with groundwater recharge. Findings Based on the analysis it was determined that the east-west corridors that should be considered for Phase 2 Study are: ^ Asbury Road, Pennsylvania Avenue, University Avenue, Loras Boulevard Each of the corridors lack adequate existing public right-of-way width to make significant traffic capacity or Complete Streets amenities improvements without significant impacts to private property. Vehicular capacity improvements that could be considered include: ® Adding Additional Thru Lanes ® Adding Additional Turn Lanes At Selected Intersections ^ Optimizing Traffic Control • Reversible lanes ^ Roundabouts An acceptable corridor capacity improvement scenario and inclusion of various Complete Streets amenities in the conceptual design of the corridors will be determined based on input from the Dubuque City Council and the public.
