| Subject |
| Resolution 2017-23 - Authorizing an Agreement with Kimley-Horn and Associates, Inc. for Traffic Signal Optimization Study |
| Background |
The City of Brentwood applied for and received $216,000 in federal funding for a Congestion Mitigation and Air Quality (CMAQ) grant through the Metropolitan Planning Organization (MPO) and the Tennessee Department of Transportation (TDOT). Staff plans to utilize the CMAQ funding to improve traffic flow along four of the City’s primary arterials: Concord Road (SR-253), Moores Lane (SR-441), Wilson Pike (SR-252) and Murray Lane. All four of these roadways are classified as ‘Urban Minor Arterial’ based upon the Tennessee Department of Transportation’s urban functional classification system prepared by the Long Range Planning Division. These four corridors include 31 of the City’s traffic signals. This grant is 100% reimbursable with no match; therefore, there is no out of pocket cost for the city.
This project provides for the development of synchronized/optimized signal timings along each corridor. Optimized signal timings will result in improved mobility by reducing traffic delays, pollutants emitted while vehicles are idling, and fuel consumption. Additionally, roadway capacity will be preserved, which will result in an extended life for the existing roadway network.
Primary activities of the signal timing portion of the project include the collection of data, analysis of the corridors, implementation of the signal timings, and documentation of recommended improvements. The data required for analysis includes full traffic counts, including turning movements at each intersection, existing signal timing data, and travel time runs. The data collected will be entered into Synchro (traffic simulation software) to validate existing conditions and develop coordinated signal timing plans. Once the timing plans are complete, they will be implemented and adjusted as necessary by the consultant to provide maximum efficiency.
In addition to improving traffic flow at 31 signalized intersections, a preliminary engineering phase will be conducted for these intersections. The preliminary engineering phase will assess curb ramp compliance with ADA regulations. Additionally, this phase will provide an up-to-date signal inventory and identify any pedestrian signal deficiencies and any faulty vehicle detection equipment at each of the traffic signals. This will allow for improved management of Brentwood’s signal system and improve safety for drivers and pedestrians. A list of the intersections involved in this study is included in the attached consultant agreement and a map is also attached to this agenda item.
Staff advertised for statements of qualifications from transportation consultants on January 4, 2017. A copy of the Request for Qualifications (RFQ) is attached. Five responses were received, and the responses were reviewed by the City's Consultant Evaluation Committee. Each response was evaluated based on the criteria specified in the RFQ. Kimley-Horn and Associates, Inc. received the highest score. (See scoring matrix, attached.) Based on the scoring, and in accordance with our consultant selection policy, staff contacted Kimley-Horn and negotiated the fee to provide the desired professional services. A copy of the fee proposal/agreement with Kimley-Horn is attached. The fee to accomplish the project is $212,000 which is within the $216,000 grant funding. Staff recommends approval of the agreement with Kimley-Horn. If approved, staff intends to begin work immediately and with a targeted completion of six to eight months.
Please direct any questions to the Engineering Director. |
| Staff Recommendation |
| Staff recommends approval of the proposed agreement with Kimley-Horn. |
| Previous Commission Action |
| At its June 27, 2016 meeting, the City Commission approved an agreement with TDOT to allow the City of Brentwood to locally manage this CMAQ grant project. |
|
| Fiscal Impact |
|
|
| Fiscal Impact: |
| The grant is a reimbursable type grant with no match. The city will pay invoices using funds established in the approved CIP and then request reimbursement from TDOT. Kimley Horn's fee is $212,000 and the city may incur some administrative costs such as advertising and document reproduction charges, therefore staff is requesting authorization to utilize the full grant funding of $216,000 if necessary. |
