1. An integrated automatic system for monitoring traffic flow and adherence to traffic laws and regulations comprising: a passive road sensor for detecting a vehicle traveling on a road by generating and detecting a vibration caused by impact of wheels of the vehicle with a rigid member extending across a traffic lane, wherein the passive road sensor comprises a detector which provides a signal dominated by said vibration and an enclosure for housing the detector, the enclosure forming the rigid member and being positioned such that the enclosure remains exposed within an opening in the road which essentially spans the entire width of the traffic lane; and an integrated event recording and reporting system in direct communication with the passive road sensor comprising a processing unit, a video camera and a communication module, the processor unit to engage the video camera to capture an image of the passing vehicle in response to the vibration signal and to communicate data corresponding to the image to a separate control unit by means of the communication module.
