Regional Traffic Signal Upgrades

Replace 99 traffic signal controllers at 99 intersections with upgraded equipment in unincorporated Clackamas County and areas within City of Lake Oswego, Wilsonville, Oregon City, Milwaukie, Gladstone, and West Linn. 

The new controllers will allow for improved timing at intersections and to use performance data tracking that will inform future changes of the traffic signal. The upgraded traffic signal controllers will connect with the region's central signal system. The central signal system allows agency engineers to monitor operations, making changes in real-time, and receive alerts and information to better inform signal operations and repairs. 

These upgrades are a regional priority supported by TransPort, a group that makes recommendations on transportation system management and operations needs in the region to the Metro’s Transportation Policy Alternatives Committee. The project is supported by Metro's Transportation System Management and Operations Program. 

Why

To increase reliability of traffic signal system, improve travel times and increase safety for all modes of travel at intersections.
