HSIP Signal Enhancements

Description

Overview

The County of Marin has proposed traffic signal safety enhancements at 51 signalized intersections throughout unincorporated Marin County and in 11 incorporated cities and towns. The project is a joint effort with the County of Marin acting as the lead agency coordinating with the cities and towns.

The proposed project safety improvements include: upgrading signal heads to 12" LED signal heads, adding signal head backplates, adding pedestrian countdown heads, adding audible pedestrian signals at pedestrian push buttons, updating signal hardware to incorporate Lead Pedestrian Intervals at crosswalks, and adding video or advanced detection loops for advanced dilemma zone detections.

There are no below ground excavation or earth disturbance activities associated with any of the proposed improvements. The upgrades have the potential to improve public safety by reducing the incidence and severity of collisions at the intersections.

Funding

The estimated $2.8 million budget is being funded by a California Highway Safety Improvement Program (HSIP) grant.
