Adaptive Traffic Control Signal Upgrades - Day Hill Road Corridor

Adaptive Traffic Control Signal Upgrades - Day Hill Road Corridor
Expected project duration: August 1st, 2016 - December 31st, 2017

Project Update - September 27, 2016

Qualifications packages were solicitied from consultants for the design phase of this project in August.  The qualifications submittals are currently being reviewed by town staff and interviews with selected candidates are expected to take place in mid-October.


Project Update - August 3, 2016

Recently, the town was awarded a grant in the amount of $1.3 Million under the Connecticut Department of Transportation's Congestion Mitigation and Air Quality (CMAQ) Improvement Program


At this time, the Town is seeking to receive the qualifications of interested traffic engineering firms to perform design services for implementation of  an adaptive traffic control signal system, utilizing Adaptive Signal Control Technology (ASCT), along Day Hill Road.  Letters of interest must be submitted by September 1, 2016.  Full details on this solicitation can be found on the Engineering Department's Main Page as well as on the Town's RFQ/RFP Section of the website.


If you have any questions at this time, please contact Victoria Houle, Project Engineer, at (860) 285-1862.

Project Background

In 2009, a study was funded by the town and completed by Vanasse Hangen Brustlin (VHB) to analyze the Day Hill Road Corridor and identify capacity improvements which would enable the Corridor to effectively manage the projected increases in vehicular traffic in future years.  The study identified three major initiaives for town consideration including: traffic signal coordination upgrades along Day Hill Road, installation of right-turn lanes at various intersections, and lane widening between the area of Lamberton Road and Interstate I-91 and Poquonock Avenue.  


Addressing the traffic signal timing along Day Hill Road was determined to be the highest priority among these recommendations.  Improving the traffic signal timing will alleviate traffic congestion and subsequently improve air quality.
