Approval of the Puget Sound Regional Council (PSRC) Federal Grant, in the Amount of $865,000, for the Adaptive Signals Downtown Project and to Add the Project to the 2023-2024 CIP
OVERVIEW STATEMENT:
recommendation
The Adaptive Signals Downtown project received a grant from the Puget Sound Regional Council (PSRC) in the amount of $865,000. Council acceptance of this grant is required. The project is not included in the 2023-2024 CIP and Public Works is requesting Council add the project to the approved CIP.
This Adaptive Signals Downtown project will install new traffic control systems in downtown, capable of adjusting signal timings, and operations in real-time. This will reduce travel times through downtown and reduce wait times for pedestrians. With the arrival of light-rail in Downtown Redmond, this updated signal system will be key in responding to the change in traffic conditions expected through downtown.

• Other Key Facts:
The project was previously an approved project funded by the City in the amount of $1,000,000. The project completed preliminary engineering in November 2020. Council decided not to move forward with the project in the 2021-2022 budget to fund other priorities.
Adaptive signal control is a technology that adjusts traffic signal timing based on real-time traffic data, aiming to optimize traffic flow and reduce congestion. It is especially effective for roads that experience variable and unpredictable traffic demand, where conventional signal systems cannot keep up with the changing conditions. Adaptive signal control can also benefit pedestrians and active transportation modes by reducing delays and improving service. Adaptive signal control can also respond to changes in traffic patterns caused by new work commute options and the opening of transit stations, which can affect the demand for different directions and movements at intersections.
OUTCOMES:
The proposed adaptive traffic signal control system will measure real-time traffic fluctuations and automatically adjust signal timings more efficiently than our current system. Other agencies have demonstrated substantial delay reduction, especially when conditions change unexpectedly due to weather, lane closures, or surges in demand.
