Traffic signal priority clears the way for your vehicles

Traffic signal priority systems are a type of system that allows the normal operation of traffic lights to be preempted. The most common use of these systems is to manipulate traffic signals in the path of an emergency or transit vehicle to give it right-of-way, to help reduce response times, assist with on-time performance, and enhance traffic safety. 

Traffic signal priority prevents traffic delays and congestion

Traffic Signal Priority (TSP) reduces dwell time at traffic signals for transit vehicles by holding green lights longer or shortening red lights. TSP may be implemented at individual intersections or across corridors or entire street systems. Signal Priority is used to provide extra green time at intersections to larger and street-running transit vehicles, such as trucks, buses, light rail, and streetcars. By helping the bus or truck avoid a stop at a red light, this additional time can help the bus arrive at stops on-time, and can prevent traffic delays and congestion

Traffic signal prioritization boosts service reliability

The benefits of Traffic Signal Priority for public transport vehicles are to reduce delays at intersections, and hence reduce overall running time. Reducing the variance of time spent stopped at traffic signals, improves service reliability.

Each customer had quite different traffic signal control systems

We have integrated our ITS solution to traffic signal priority systems for each of these transit agencies as part of our ITS solution.

After completion, a Traffic Signal Priority is requested for vehicles running trips that are late by a configurable threshold measured from the last timepoint.

TSP systems we have integrated with

  • Opticom/GTT/Miovision type beacon systems SCATS
  • Peek Traffic
  • Siemens, TRL SCOOT systems
  • Iteris

    In each case, we investigated the nature of the system, worked out the integration approach and successfully deployed our solution.

"When we started looking for a replacement ITS system in 2006, I stated that I wanted a partner rather than a vendor. Now that I'm retiring, I wanted to call you and let you know that we found that partner, and it was you."
