2013 Regional Transportation Authority Plan Report

RTA Ballot No. 36INTeRsecTIoN sAfeTy ANd cAPAcITy UPgRAdes

overview

Intersection Safety and Capacity Upgrades (RTA Ballot No. 36) are part of the Safety Element of the RTA plan adopted by voters in May 2006. The sub-element for intersection upgrades was allocated $100 million, or 5 percent, of the project funding identified in the plan to improve regional mobility.

The RTA plan did not identify specific intersection im-provements to be constructed as a part of this sub-ele-ment but showed in an illustrative fashion a distribution of intersection projects across the region, including intersec-tions that would be built on regional corridors listed on the ballot as Roadway Element projects.

Outreach materials of the RTA plan shared with the public prior to the vote indicated a total of 200 intersection im-provements to be built across the region.

Progress To date

Through March 2013, RTA member jurisdictions have completed102 Intersection Safety and Capacity Upgrades. Additionally, another 21 major intersections have been improved as a part of Roadway Element projects, bringing the total number of improved intersections to 123. After nearly seven years into the RTA plan, the volume of com-pleted intersection improvements compares favorably to the pre-election commitment to improve 200 intersec-tions over the life of the RTA plan.

The scope of improvements varies substantially, from the upgrade of traffic signal components to complete intersection reconstruction to add more turn lanes and drainage improvements. The costs of these improvements have been just as varied, ranging from as little as $26,000 for the installation of countdown pedestrian signals at 15 Oro Valley intersections to $7.8 million for the Grant Road and Craycroft Road intersection improvement.

While the vast majority of the completed projects funded under the sub-element have been modest in size, the costs on 14 projects exceeded $900,000, constituting 76 percent of the total funds programmed in the sub-element.

The RTA Board has approved $63,901,000 (63.9%) in project commitments out of the sub-element’s $100 mil-lion budget. To date, $48.9 million in project reimburse-ments have been made, with $44.1 million of that amount expended on projects which are now complete. Pima

Intersection safety and capacity Upgrades

County, the cities of Tucson and South Tucson, and the towns of Oro Valley, Sahuarita and Marana have received project funding. The distribution of project funding is shown on the following graph.

Programmed funding for RTA Ballot No. 36, Intersection Safety and Capacity Upgrades

Of the 102 intersection projects completed, 11 required supplemental funding due to project cost increases. Of these 11 projects, two received additional funding from the implementing jurisdiction; the remaining projects received supplemental funding by RTA Board action. The total amount added to these projects was $3.68 million. It should be noted that one project, the Wilmot/Park Place intersection, returned approximately $1.48 million which was determined to be overprogrammed. The 14 largest projects (those over $900K) included four of the projects which required supplemental funding (including both of the projects with additional jurisdictional funding). The to-tal amount of RTA funding programmed for these projects was $36 million, of which $33.4 million was expended. The remaining balance of $2.6 million represents a 7.2 percent savings from the programmed amount.

Recognizing the savings from the completed, previously programmed projects, the RTA Board programmed an ad-ditional six projects, with a combined funding amount of $3.9 million, at its January 2013 meeting.

The following pages show the specific benefits of the 14 largest intersections (costs exceeding $900,000) funded through the Intersection Safety and Capacity Upgrades sub-element of the RTA plan.

RTA Ballot No. 36

Intersection safety and capacity Upgrades

grant Road and craycroft Road Intersection

ToTal projecT cosT: $7.968 million $7.772 million pro-grammed

scope of work:Double left-turn lanes added in all directions.

Right turn lanes added in all directions.

Reconstruct Alamo Wash bridge on Cray-croft.

New median islands on Craycroft Road.

New bus pullouts on Grant Road with shelter at TMC.

Construct continuous sidewalks.

Upgrade traffic signals.

Reconstruct or overlay existing pavement through project limits.

compleTed: FY 2010

The Grant Road and Craycroft Road intersection was one of the first major intersection projects completed with RTA funding and is the most expensive intersection project to date. The project received an initial $4.5 million funding allocation, which was increased to $7.772 million due to escalating costs. The project was originally bid in 2007, but the bids were rejected due to the bids exceeding available funding. The project was downscaled to reduce

costs and additional funding was programmed.

The completed project substantially improved intersection performance, with significant reductions in overall delay. The project has reduced delay at the intersection by 24 percent during the morning rush hour, with the evening rush hour delay reduced by 37 percent.

Before reconstruction

After reconstruction

ToTal projecT cosT: $4.77 million $4.997 million pro-grammed.

scope of work:Right turn lanes added in all directions.

New bus pullouts on Campbell (north of intersection) and Ft. Lowell Road (east & west of intersection) with shelters.



Drainage improve-ments.


compleTed: FY 2011

ft. lowell Road and campbell Avenue Intersection

The Ft. Lowell Road and Campbell Avenue intersection improvements were completed at a cost of $426,000 below the programmed amount. Additional funds will be returned as a result of the sale of the remnant parcel at the northwest corner of the intersection. The improve-

ments are estimated to reduce the average intersection delay (per entering vehicle) in the evening peak period from 50.9 seconds to 35.9 seconds, a reduction of nearly 30 percent.



starr Pass Blvd. and Mission Road Intersection

ToTal projecT cosT: $3.878 million $4.65 million pro-grammed.

scope of work:Reconstruct ramp from northbound Mission to eastbound Starr Pass.

Reconfigure intersec-tion to have Mission Road tee into Starr Pass, with Grande Street tee into Mission Road.


Reconstruct traffic signal.


compleTed: FY 2011



The Starr Pass Boulevard and Mission Road intersection improvements were designed to simplify operations at the intersection and favor the heaviest traffic movements with improved geometry. The changes also helped to reduce

traffic through the adjacent neighborhood. The final project costs were over $700,000 below the programmed amount. The improvements are estimated to reduce delay per vehicle by 9 percent in the evening peak hour.

ToTal projecT cosT: $1.475 million $1.7 million pro-grammed (after $1.48 million released).

scope of work:Reconstruct continuous flow Tee intersection (Florida Tee) to provide three lanes of continu-ous northbound travel.

Add southbound right turn lane to improve safety.

Reconfigure median island.



CoMPLeTeD:

FY 2010

Park Place and Wilmot Road Intersection



The Park Place and Wilmot Road intersection improve-ments established a continuous flow intersection. Prior to the project, two of the three northbound lanes were con-tinuous flow. However, the 3rd, inside lane was subject to

signal operations. This created driver confusion and delay. Total vehicle delay has been reduced during the evening peak hour by 15 percent.

Houghton Road and sahuarita Road Intersection



This project reduced congestion and enhanced safety. It included replacing the stop sign controlled intersec-tion with traffic signals, removing the existing median and adding turn lanes on the approaches; adding a westbound and southbound right turn lane; construct-ing drainage improvements such as culverts, pipes and

ditches, and adding bicycle lanes, pedestrian access ramps and crosswalks for pedestrians. The project was completed at the programmed amount. However, local funds were required to fully fund the improvements. The project re-duces delay by 13 percent in afternoon peak, and address-es a number of safety deficiencies previously identified.

This project included realignment of the intersection along with widening both roads from two to four lanes. Turn lanes and multi-use lanes also were added to miti-gate congestion and improve safety. The project was

delivered for the programmed amount (in conjunction with Silverbell Road improvements) and has reduced peak hour intersection delay by 48 percent.
