Wireless and Distributed Intelligent Signal Heads

The traditional traffic signal system with 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:
