    • 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.
    • 用于监测交通流量和速度的系统具有带状构件(1),其包括在由介电隔离层(4)分开的不同层(2,6)上的电触头(3,7),使得当车辆 在条带上驱动,带上的车辆的重量通过介电间隔物中的孔(5)封闭触点,以使得监视和/或定时装置被激活并随后被去激活。 监视和/或定时装置是可编程的,以区分车辆类型以及在同一时间通过条带的多个车辆之间。
