Abstract

PURPOSE:To improve more the detection accuracy of occurrence of an accident by outputting an accident occurrence signal when a specific vehicle sensor outputs consecutively a sensing of presence of a vehicle in response to a sensing signal group given for the prescribed number of times secularly from the vehicle sensor. CONSTITUTION:Plural vehicle sensors 3 sense vehicles for a prescribed time interval and the sensors 3 are arranged at an interval below the mean vehicle length, then all vehicles on a road 1 for the set section are detected surely. Then if an accident takes place and the same vehicle is sensed consecutively by the same sensor 3, the specific sensor 3 outputs consecutively the sensing signal specific to the vehicle and an accident detection means 6 outputs an accident generating signal. Thus, since the accident occurrence signal is outputted when the vehicle stops at a position corresponding to the specific vehicle sensor, the accident is sensed surely independently of the quantity of traffic and the detection accuracy is improved.
