An objective of Automated Highway System (AHS) is a system that will be accident-free in the absence of malfunctions. The approach used in the study was to proceed in a series of steps. The first step was empirical and was used to identify the top level functions that would take place in an AHS. These functions were entry into the AHS, travel on the AHS, and exit from the AHS. The next step was heuristic, studying the General Estimates System (GES) data to learn what kinds of accidents occur most frequently on today's interstate. The third step was analytical and assessed the impacts on the system design depending upon the implementation approach. The final step showed how a deductive approach could be used as a method to quantify safety benefits achievable by the AHS. With each ERSC come added features that potentially increase the safety of the system. A method is shown how this benefit can be quantified by analyzing accident data and determining what types of accidents will be mitigated by the introduction of new technologies. From this analysis, the type and number of accidents reduced can be determined for each ERSC and a qualitative and quantitative measure of overall system safety can be made.
