Automatic traffic condition control system.

摘要

Vehicle traffic is controlled by equipping each vehicle (2) with a memory-card or chip-card reader (3) connected to receiving means for receiving a signal emitted by a traffic control post (5) or station. The use of such cards permits generalised usage by avoiding the need to standardise the devices to be installed permanently on the vehicles (and which can therefore be of varied technology) and by limiting the standardisation only to limited elements: the chip cards (4). <IMAGE>
