Device for monitoring traffic violating and for recording traffic statistics
First Claim
1. A traffic monitoring device comprising:
- (a) sensor means responding to the passage of vehicles for providing vehicle passage signals,(b) means for detecting violations of traffic regulations by passing vehicles and signalling a camera means,(c) photographic camera means for recording such a vehicle, the photographic camera means being released to take a photograph upon receiving said signalling from the violation detecting means,(d) clock means for providing time information associated with said passage of said vehicles.(e) electronic memory means arranged in said traffic monitoring device and connected to said sensor means and to said clock means for memorizing, for later evaluation, the number of all said vehicle passage signals and the respective times of passage of said vehicles past said sensor means, irrespective of whether or not a violation of traffic regulations has occurred,(f) wherein violation detecting means and said clock means are arranged in a unit arranged at the side, where the traffic is to be monitored, and said memory means are also arranged in said unit.

Abstract
A photographic traffic monitoring device comprises a sensor responding to passing vehicles, for example, an induction loop imbedded in the road for monitoring traffic lights or a Doppler radar. From a signal evaluation it is determined whether a detected vehicle has violated a traffic regulation, e.g. exceeded the allowed maximum speed limit. When such a violation takes place, a camera is automatically released and the monitored vehicle is photographed. In order to collect data for statistical purposes about traffic events obtained with such devices, a memory function is provided. This function records events detected by the device, events which are not restricted to violations of traffic regulations.

5. A traffic monitoring device comprising:
-
sensor means responding to the passage of vehicles for providing vehicle passage signals, clock means for providing time information associated with said passage of said vehicles. means for detecting violations of traffic regulations by passing vehicles, said violation detecting means comprising means for measuring the speed of vehicles passing by and the means for detecting violations associating with means for signalling to a camera means upon detecting a violation, said violation detecting means and said clock means being arranged in a unit located at the site, where the traffic is to be monitored. photographic camera means operable for photographing, on a photographic film, only violating vehicles, said camera means being controlled to take a photograph upon receiving a signal from said means for signalling associating with the violation detecting means and electronic memory means arranged in said unit of said traffic monitoring device and connected to said sensor means and to said clock means for memorizing, for later statistical evaluation, the number of said vehicle passage signals and the respective times of passage of said vehicles past said sensor means, irrespective of whether or not a violation of traffic regulations has occurred said speed measuring means being also connected to said electronic memory means for memorizing the speeds of said vehicles for later statistical evaluation regardless of whether such speeds are excessive or not. - View Dependent Claims (6)
