摘要：PROBLEM TO BE SOLVED: To facilitate processing, and to enhance detection precision. SOLUTION: A road monitoring system for analyzing a monitored image data provided by imaging a road using a camera 2 to monitor a situation as to a vehicle traveling on the road is provided with a vehicle detecting means 16 for finding an existence area of the vehicle traveling on the road, based on the monitored image data, to detect a vehicular position in the existence area, and a vehicle tracking means 17 for finding a speed using a distance difference and a time difference between the last vehicular position and this time vehicular position, for conducting weighting corresponding to the vehicle using a predetermined prescribed speed as a reference, and for detecting generation of the stopped vehicle based on an accumulated weighting value for the one vehicle to track the vehicle.
