A simple method for the recording, documentation, and analysis of metric measurable traffic accident information using photogrammetric related techniques is presented. Using nonmetric cameras and perspective grid theory, this economical system will meet or exceed the quality of traffic accident diagrams prepared using conventional investigation survey techniques. Integrated procedures for stereoscopic coverage and extension from planimetric to three dimensional mensuration are developed. A literature review is included which describes the European use of stereometric systems applications to traffic accidents and their success with these systems. Reference is also made to courtroom admissibility of the accident diagrams and photography. Also, a pilot project conception is offered. This conception minimizes training burdens, can be initiated in phases and can be evaluated without disrupting current procedures. Author
