CTDOT Green Light is a transportation initiative that will update Connecticut’s traffic signal system timings. This will result in a wide range of transportation economic and environmental improvements that increase people’s quality of life by meeting user needs. The project offers better traffic flow to improve safety, reduce congestion, save fuel, and improved air quality.
There are several key components of CTDOT Green Light that are wide reaching and include:

This project is currently implemented in the Capital Region Council of Governments (CRCOG) area. This is a multi-phase project in which all four phases have been completed. Annual benefits resulting from signal timing changes include the following performance measures.
Cumulative Performance Measure Phase Results
Each phase of the project consisted of improvements to signal timings of approximately 300 signals across the CRCOG area. CTDOT will continue to monitor the traffic signal operations and update every three to five years.
