Concurrent lighting system on roads in practice

The concurrent lighting system was developed for interactive control the street luminaires located along the chosen road. The individual light spots are switched on and off, depending on the needs arising from the of user presence. After more than a year of operation, presented system was evaluated by economic effects. Real consumption of electrical energy by operating concurrent lighting system was compared with other standard lighting control systems such as steady light all the time and power reduction during deep night, realized on the installation of the same nominal power.
