Traffic Signal Timing

Project Scope

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 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. This project is 100% funded through grant money from the Virginia Department of Transportation's Highway Safety Improvement Program. 

Project Limits

The project covers 28 traffic signals citywide. 

Project Schedule

Data Collection, Inventory, and Travel Time Study: June to September 2017
Analysis: October 2017
Implementation: December 2017
