Safer intersection design using an expert system.

This paper outlines the development of an expert system. The aim is to determine the most appropriate form of intersection treatment and control. The software package is being developed using an expert system shell. It can be further developed and easily modified for local or international use.It prompts the user for a wide range of information ranging from road network planning, to flows, to accident history. The software package will firstly determine the appropriate form of treatment and control from the four main intersection categories. The parameters taken into account are safety, capacity, and delays. The package attempts to determine the most appropriate form within these category options. This requires a higher degree and less well-defined evaluation level.
