Traffic Signal Replacement



Project Name: Traffic Signal Replacement

Department: Public Works Department

Start Date: 7/01/2023

End Date: Ongoing


These funds will be used for the replacement/upgrade of traffic signal hardware and electronic equipment that is beyond its useful life. Including mast arms, signal heads, electronic controllers, vehicle detection loops, conduit, wiring, uninterruptible power supplies, and switches.


Objectives: To proactively fund the replacement cycle of the City's aging traffic signal infrastructure for traffic conveyance efficiency, asset integrity, and safety

Status: Public Service is currently partnered with an engineering firm and conducting a Traffic Signal Condition Survey to full evaluate the physical and electronic status of the City's traffic signal infrastructure. A priority based report should be available by end of this year for Phase 1 and Phase 2 of this condition survey effort detailing the condition of the asset inventory. Due to the documented condition recorded during the survey we recently received an itemized cost estimate for five (5) of our "Priority 1" intersections that were identified based on a very poor assessed condition (please see attachment). The total estimated replacement costs for these 5 critical condition signal intersections is $3,628,785. Inflation and prolonged material lead times makes this extensive outlay more difficult as current estimates put required material and installation out 8-12 months upon order. Based upon these factors and early input from the consultant it would be ideal to get on a 2 intersection replacement cycle per year in order to start working through the backlog of poor condition based traffic infrastructure. The estimate funding amount to accomplish this is $1 million per year.


Chapter 6 : Transportation

Goal 1. Complete Streets

Create and maintain a connected network of safe, convenient, and pleasant accommodations for pedestrians, bicyclists, and transit riders, including people of all ages and abilities.

Goal 3. Efficient Mobility and Access

Maintain a safe and efficient transportation system to provide mobility and access.

Chapter 9 : Community Facilities and Services

Goal 1. Efficient Planning for Facilities and Infrastructure

Prioritize efficient construction and maintenance of all community infrastructure and facilities, and ensure that infrastructure capacity is built and maintained in line with growth or declining demand, as appropriate.

Cost Estimate

Operating Impacts

Equipment will continue to degrade and will generate exponentially more repair work and downtime, causing added costs and negative impacts to traffic conveyance. The age and condition of the identified critical intersections also presents safety concerns that need to be addressed as soon as possible, and then moving forward on a proactive replacement cycle
