Project Overview

The Dumbarton Corridor Improvement Project (Project) aims to improve reliability and reduce travel times for transit service. The Project will include the installation of a Transit Signal Priority (TSP) system, bus queue-jumps, and bus stop improvements and relocations. These improvements will ensure that the State Route 84 corridor in the cities of Union City, Fremont, Menlo Park, and Palo Alto provides transit services that better connect residents and businesses in the South Bay to job centers in the East Bay and on the Peninsula.

Project Description

  • Installation of Transit Signal Priority (TSP) Technology, resulting in priority requests upon bus arrival and additional green light time to reduce time waiting at red lights.
  • Bus Queue-Jump Signals, leading to buses bypassing queued vehicles, typically via the right-turn lane.
  • Bus Stop Improvements, including paving planter strips and sidewalk area rebuilding to enhance rider safety and access at bus stops.
  • Bus Stop Lengthening, providing buses with additional space to align with the curb at stops, to improve boarding access for passengers while improving traffic flow.
  • Bus Stop Relocations, proposing to move select stops from the near-side (before a signal) to the far-side of intersections (after a signal). This will result in buses using the transit signal priority for faster bus travel through signalized intersections (see below).
  • Bus Stop Removal, reducing travel times by spacing out bus stop locations based on ridership, distance between bus stops and local needs.
