Traffic Light Priority System


A traffic light priority system is used to control traffic lights to permit a much more fluid circulation of your vehicles in zones where no dedicated lane is available. Infodev's traffic light priority system is different from other such systems in that it uses a distributed architecture that requires no human intervention. Our sophisticated data acquisition systems know when to require a lengthening of the green light or a shortening of the red one, and simply do so automatically.





  • Our distributed system is completely automated and requires no intervention from the driver or a central operator.
  • Interface with the traffic light controller is simple and easy to set up.
  • Helps reduce lags caused by traffic jams and improve schedule adherence.


Infodev's traffic light priority system uses a distributed architecture where equipment is installed in the vehicles and the traffic light controller.

The data from the vehicle and the traffic light controller computers can be downloaded for analysis with our proprietary software or any commercially available spreadsheet software.
