RE: Application Authorization for a Traffic Safety Improvement Grant to assist
with funding proposed Northwest Arterial and John F Kennedy Road
Intersection Northbound Left Turn Lane Improvement
INTRODUCTION
The attached resolution provides the authorization for the City of Dubuque to officially
submit an application for a Traffic Safety Improvement Grant to assist with funding for
proposed improvements to extend the eastbound Northwest Arterial dedicated left turn
lane onto John F Kennedy (JFK) Road.
BACKGROUND
Based on the operational and capacity challenges the City has experienced at the
Northwest Arterial and JFK Road intersection, in 2018 the City completed the
construction of new 250-foot exclusive right turn lane along the existing northerly
approach on JFK Road.
Now with the improved operations of the northerly approach right turn lane at the
Northwest Arterial and JFK Road intersection, staff is proposing to focus on
implementing capacity improvements to the existing eastbound Northwest Arterial
exclusive left turn lane onto JFK Road.
EXISTING CONDITIONS
The existing eastbound Northwest Arterial dedicated left turn lane onto JFK Road is
approximately 125' in length and is currently under capacity with left turn traffic
movements regularly backing up into the inside eastbound thru-lane. Based on existing
conditions, the left turn lane onto JFK Road does not have adequate que storage length
to support traffic volumes and does not efficiently handle left turning traffic movements
during peak travel times.
PROPOSED TURN LANE IMPROVEMENT
Based on the current operational and capacity challenges the City is experiencing at the
NW Arterial - JFK Road intersection, the proposed left turn lane improvement includes
extending the existing eastbound Northwest Arterial dedicated left turn lane onto JFK
Road to an approximate 400' storage length. Attached is an aerial photo exhibit which
shows the proposed turn lane improvements.

RECOMMENDATION
I recommend that the City submit the grant application with the lowa Department of
Transportation for a Traffic Safety Improvement Grant to assist with funding for
proposed improvements to extend the eastbound Northwest Arterial dedicated left turn
lane onto John F Kennedy Road.
BUDGETIMPACT
This grant application is requesting funding from the State of lowa's Traffic Safety
Funds. The total cost of this improvement is estimated at $161 ,000.00 of which
$133,000 would be requested as part of the grant. If awarded, the Traffic Safety
Improvement Program funding would cover 83°k of the improvement cost and the City
would need to provide an additional $28,000 to cover engineering design and
construction administration related costs which would be budgeted in FY 2021 .
Construction is anticipated to take place in the summer of 2021 .
There is no other fee associated with the application process since the City is utilizing
the services of the East Central Intergovernmental Association (ECIA).
ACTION TO BE TAKEN
The City Council is requested to adopt the attached resolution authorizing the filing of
the application with the lowa Department of Transportation for Traffic Safety
Improvement Program funding to assist with funding for proposed improvements to
extend the eastbound Northwest Arterial dedicated left turn lane onto John F Kennedy
Road.

B. NARRATIVE
Existing Conditions
The project proposed in this application will in�pro��e saTety at the intersection of Northwest Arlerial I
Iowa Highway 32 (\�orthwest 9rterial) and John F Kennedy Rd (JFK Rd} in Dubuque, Iowa. Iowa High-
way 32 {Northwest Arterial} is a five-n�ile long state highway that primarily runs north and south across
the western portion of the Gitv of Dubuque.Northwest Arterial's northern tern�inus is at its intersec-
tion with US Highway 52 and its southern tern�inus is at its intersection with US Highway 2U. JFK Rd
is a 11-Sinor Arterial that runs north and south across the Gitv oi Dubuque. Northwest Arterial is a vital
transportation corridor in Dubuque, as is one of Tour corridors that carry the nzajoritv eastlwest trafiic in
the citv.
Geometry of the Intersection
• The intersection af Northwest Arterial and JFIC Rd is a faur-way signalized intersection.
. The east leg of the inlersecrion has one left turn lane and two through lanes.
• `llre west leg of the intersectian has ane left turn lane and two thraugh lanes.
• The north Icg oi'lhe interseclion has onc Icfi lurn lane and one lhrough anil one righl lurn lane.
• The south leg of the intersection has one left turn lane and one through!right hzrn lane.
The wesl leg approach of thc Norfllwesl Artcrial and JFK Rd intcrseclion has t��o tllrough (ai}es and
one left lurn lane. The]eft turn movement to go north is a��ery heavy movement. This left turn lane is
favored bv mann dricers going norfll becausc if]eads fo a ten fic(d soccer comp(ex, a retia( c<»nmercial

tioa}s :1na(ysis in 2()()7. Thc Iow�a i?epartment of Transportation commissioned both studies. Thc studics
indicatea that operationa] and safetv concerns will continue to increase with the dramatic growlh of traf-
fic volumes in this corridor. The staristica] data of the 2035 and 2040 Dubuque 1'Ietropo(itan Area Trans-
portation Study Long Rai}gc p(ai}s validates that Norfhw�est Arterial al Pei}nsylvania flvc intersection has
a significanf"cras11 intcresf':
Praject Concept
The proposed improcements at Norfllwesf Artcrial and JFK Rd consist c�f adding more storage to fhe
left lurn only laa}e by ia}crcasing the lane length on to thc cvest. Ia}creasing thc storage of thc dedicafed
left lurn ]ane w�ould allow frce fratlic moeements for thc through lanes. TIZis imprc>ecment in e(�iciencv
wou(d result in minimized qucuc lengths and hloc kages of through lanes bv Ict`l tura}ing vchic les. These
lane im�rovements would also allow sustained coordination of thc Northwesl Arterial, which wou(d

Traffic
tiVith the growth of the Gity of Dubuque to the west and north, the daily traffic aoluine entering the
intersection has increased. A review of the Iowa DOT Annual A��erage Dai1y Traffic(AADT} inaps Tor
the Gitv of Dubuque found that over 20,300 vehicles per day traveled through the intersecrion in 2017. A
review of historical9ADT data for the intersection is shown in the following table.

Using the results oT the HDR study, slaff calculated an annual aaerage traffic growth rate oT 4.Os°io. to
be conservative staff used 1.5% as a rate oT increase in annual traffic growth in the&enefitlGost Safety
Anal��sis.
Crashes
Grash data Tor the intersection was coinpiled using the Iowa Crash 9nalysis Too1 (IC9T} online data by
the Iowa DOT. There ha��e been a total of 62 crashes at this intersection over the Iast 11 years, an a��er-
age of 5.6 crashes per year Trom 200&through 201s.�Vhile none oT these crashes ha��e in��oh�ed fatalities,
approxinzately 51.6% (33 of the 62 crashes) have resulted in personal injuries and 4&.4%are property
damagc.
OT b2 crashes,� happened because vehicles were following dose and did not have sufficient tin�e to react
to a situation. 7 of them ran the traffic signal as the wait is too long at the intersection and 16 accidents
happened due to Iost control.
The intersection also has pedestrian safety concerns due to geometry(wide intersection} and allowance
oT right turns on red. �Sany children cross the intersection before and aTter school as this intersection is
located dose to an eleinentary school. However, there is no notable crash history.
Glear Zone Requirenzents
The proposed in�pro��einent along Northwest 9rterial includes a 20-Toot clear zone, as ineasured froin the
outside pavement edge, Tor deternzinarion of embanlrnzent width.Whi1e Iowa Statewide Urban Design
and Specificarions (SUDAS) guidelines recoininend an ls-foot distance Tor higher speed transitional
facilities, 15-Teet plus a�-foot curb and gutter.Whereas, the An�erican Association of State Highway and
Transportarion Officials (9ASHT0) Roadside Design Guide suggest a range oi values for the giv�n trai-
fic and design speed of 20 to 22 Teet The slightly larger value was considered appropriate Tor the current
operational charter oi Northwest Arterial.
Manual on Unifornz Traffic Control Devices Requirenzents
The 2004 �Sanual on UniTorin Traffic Control I}��nces (�NTCD) Nnth Re��ision Nunzbers 1 and 2 incor-
porated dated 11-Say 2012 wi11 be utilized for the construction and design of the proposed iinproveinents.
Traffic control (temporary and permanent}, signing and paaement marking guidelines fronz the 1YIUTGD
w�il1 be used.
Preferred Alternative
The recoininended alternatiae from the HDR study{Pag� 22 of Northwest 9rterial Traffic Operations
Study) was to lengthen northbound IeTt-turn lane on the west leg of\�orthwest 9rterial and inake in�-
proaen�ents to trafiic sib a1 to accon�n�odate n�ore pedestrian crossings.
Increasing the len�lh of left turn Iane would a11ow unrestricted through n�oveinents. This inzproven�ent
in effidency would result in n�inin�ized queue Iengths and blockages oi through lanes. These lane im-
proaen�ents would also a11ow sustained coordination oi Northwest Arterial,which would n�inimize rear
end accidents and a11ow pedestrians to cross the intersection safely:

B. NARRATIVE
Docuinentation froin the Crash�Sodification Factors Glearinghouse shows that this inzproaeinent can
reduce the total nuinber oT crashes at the intersection by 33.&% (http:!?v+ryvw.cmTdearinghouse.orgldetail.
cfin?facid=6045). However, the in�pro��ement is not an ofFset but increase the storage of leTt turn lane.
Staff used 25% reduction in tota l nun�ber of crashes as they are not able to find a Crash 1Ylodification
Factor for this iinproveinent.
Benefit
A Benefit-Cost analysis was completed to assess the overall efFecriaeness oi the proposed iinprovenzents.
The analysis assunzed a conzbined crash reduction Tactor (CRF} of 30 based on aaailable research fron�
the Grash Modification Factors Clearinghouse and the docuinented annual growth in traffic voluines of
1.5U°o.Even though the Northwest Arterial study is shotinng a 4.Us90 increase in traffic aoluine staff used
1.5U°o as the traffic growth (growth fronz 2UU9 to 2017) to be conservative.Based on the estinzated cost
oT the project oT$160,715 and the historical crash data for the intersection, the calculated benefit of the
project was�1,745,444 equating to a &enefit-Cost Ratio of&.45 Tor the proposed improven�ents.
