Abstract:This report identifies and evaluates the application of new technology to known highway safety problems, including an assessment of functional requirements, feasibility, costs, and potential safety benefits. Findings are documented for the following subjects: (1) a typology of prevalent accident/crash types, (2) functional descriptions of 18 postulated countermeasure systems for mitigating the consequences of prevalent crash types, (3) the relationship of advanced technology to the sensing, processing, communications, and display needs of the postulated countermeasure systems, (4) potential safety benefits of countermeasure systems as expressed by estimates of the reductions in risk and severity in selected accident types, and (5) estimates of the costs of countermeasure systems and their rate of penetration into the driver-vehicle-roadway system. Conclusions and recommendations concerning the development of safety applications of advanced technology are delineated in chapter 3 of the report. The crash countermeasures identified as having high safety potential are headway control for rear-end crashes, lane-edge detection for run-off-road situations, lane-keeping systems, night vision enhancement as a crosscutting measure for various crash types, longitudinal control for pedestrians, cyclists, animals, etc., in the road, and impaired driver warnings as a crosscutting measure for various crash types.
