Abstract
  • Many hazardous locations exist on our local and street highway systems. Such hazards contribute to the frequency and severity of traffic accidents. The elimination and mitigation of the hazards reduces accident frequency and severity, as measured by the number of fatalities, injuries and property damage resulting from the accidents. The accident potential and the accident severity for the existing situation and for improvements are estimated to determine the number of fatal, injury and property damage only accidents. The reduction in accidents because of the safety improvement are used to measure the safety benefits. These benefits are compared with the costs of the improvements using economic analyses techniques. A decision making framework is developed which employs economic evaluation methods and takes account of budget limitations, to rank safety improvements. This approach leads to the selection of the most cost-effective safety improvement alternatives for highways and streets in local jurisdictions.
