Abstract: This paper introduas a method of photog rammetric surveying the road trsffic accident sites using a common cameraand mapping the road traffic ardent sites by microcomputer.This method costs less time and energy than that of mannulsurveying,and overcomes the weakness of slow speed and poor quality of mannul mapping.This mehtod is at low cost,easy to be grasped, and the accuracy is in accordance with the requirement,and can beused as a proof in court.

Key words: photogrammetric surveying, road traffic accident, computer, site map
