This study evaluated traffic signal systems for four intersections along Marshall Avenue in Williston with respect to condition and compliance with current state and federal design standards.  Recommended high-priority, medium-priority and low-priority improvements were identified including probable upgrade cost estimates depending on the existing conditions and functionality of the current signals system.

This study is a supplemental to the Exit 14 Signal Systems assessment study to investigate traffic operations at the Williston Road and Dorset Street, Dorset and Kennedy Drive intersections.  This study analyzed traffic operations with an alternative lane use by converting one of the two existing westbound left turn lanes on US 2/Williston Rd. into a third through lane and limit use of the far-right westbound lane to traffic destined to the Holiday Inn or the I-89 northbound ramp, and converting the exclusive northbound right turn lane on Dorset Street into a shared through/right turn lane at the Kennedy Drive intersection.

This study evaluated traffic signal equipment  for 13 intersections along US Route 2 and Dorset Street in the vicinity of I-89 Exit 14 in Burlington and South Burlington for compliance with current signal design standards and ability to support new traffic control technologies. The study identified short, medium and long range improvements and developed cost estimates for proposed improvements.

This study focused on evaluation of traffic signal systems for eleven intersections along the Vermont Route 15 corridor in Winooski, Colchester, and Essex for compliance with current signal design standards and for their ability to support new traffic control technologies. Recommended traffic signal infrastructure improvements were identified and prioritized. Cost estimates for these improvements were also provided.
