SIGNAL UPGRADES PROGRAM

SIGNAL UPGRADES PROGRAM

Upgrade field infrastructure and communications for traffic signals to support current and future technologies. Determine the feasibility of implementing real time signal performance data to monitor priority locations. Establish a program to guide proactive signal timing updates.

Needs

  • Limitations in remote access for real-time signal performance data (restricts troubleshooting in advance of field visit).
  • Existing communications is incongruent, non-existent, unreliable, or isolated.
  • Some connections are reliant on cellular or radio.
  • Some signal equipment is aging and in need of upgrades to support newer arterial traffic management tools.
  • Limited ability to monitor congestion levels and initiate traffic management mitigations that can improve travel time.
  • Signal cabinet controller not consistent (limited compatibility).

Related Strategies

Scoping

  • Establish existing inventory for signal equipment (cellular, radio, fiber, etc.).
  • Establish location needs for real-time signal performance data.
  • Determine cohesive and compatible software system for the region.
  • Establish formal agreements in support of interoperable communications and systems.
  • Create an implementation plan for traffic signal equipment upgrades.
  • Define maintenance needs and schedules for preventive maintenance activities.
