The traditional traffic signal system with a central traffic controller cabled to all signal heads can be replaced by intelligent („smart”) signal heads realizing a wireless and distributed traffic signal control.
– Instead of a central traffic controller the built-in logics of the signal heads provide the safe distributed operation for traffic signal control via wifi network.
– The power supply is ensured by solar cells.
– Main advantages: no substructures construction and cable need, cost-efficient system and operation.
– Main elements of the test system: Siemens PLC, Arduino, Matlab, and Siemens LED signal heads.
The built test platform for system testing:
