发明名称 SPEED DETECTOR
摘要 A system used for monitoring the flow and speed of traffic has a strip member (1) comprising electrical contacts (3, 7) on distinct layers (2, 6) separated by a dielectric spacer layer (4), such that, when a vehicle drives over the strip, the weight of the vehicle on the strip closes the contacts through holes (5) in the dielectric spacer to cause a monitoring and/or timing means to be activated and subsequently deactivated. The monitoring and/or timing means is programmable to distinguish vehicle types and between a plurality of vehicles passing over the strip at the same time.
