The development of accurate and efficient accident location systems is of prime importance to the highway and traffic engineer. During the past two years the maine state highway commission had developed a location system that is based on network principles widely used in the highway planning field. This paper describes the development of the systems, beginning with a review of alternative methods available and ending with an evaluation of the initial results as applied to the 4,600 miles of federal-aid and state highways. In brief, this initail experience with the node-link method of accident location suggests that it is an economical and flexible tool that has greatly enhanced the capability of the engineering staff to utilize factual data in the safety program.
