Traffic

Smooth real-time traffic control by SATEL radio modems.

SATEL’s radio modems contribute to making both private driving as well as public transportation more convenient.

Finding a parking space can be frustrating in congested traffic. Information about available spaces in different parking areas can be sent by SATEL radio modems to remote street displays. Drivers can avoid driving around in search of a free place and save both their nerves and the environment.

The passenger information relies on the Automatic Vehicle Location (AVL) system using GPS-satellite navigation and the odometer of the bus. The central equipment polls each bus. The central computer has continuously the data of the exact position of each bus along the route. This enables the central system to forecast next bus arrival times to all the bus stops. This data is used to update the real-time database of bus arrival times at each bus stop. This data is also sent directly to all bus stop display equipment.

Buses and trams can be given green waves in traffic lights by sending priority signals to traffic lights. By preventing unnecessary braking and stopping, travel times can be shortened; fuel consumption and emissions reduced and rides made smoother.
