Traffic Signal Timing

Background


This project aims to improve traffic safety and operations through traffic signal timing, improve the coordination of traffic signals along the City's major corridor, and reduce travel times while minimizing rear-end crashes that can result from stop-and-start traffic patterns. 

The project scope includes traffic data collection; existing conditions analysis; traffic signal optimized timing plans development with implementation; and before and after travel time studies. Additionally, the project scopes allows for some minor infrastructure upgrades at a couple of intersections. 

Project Limits


The project covers 28 traffic signals citywide.
