Development of a Value Criteria Methodology for Assessing Highway Systems Cost-Effectiveness

摘要

A resource allocation procedure was needed for selecting the most cost-effective set of countermeasures to address any given highway safety problem. The procedure developed in response to the need is divided into three phases. The methodology was applied to two highway safety problems that demonstrate its use. The best solution to the stopping-sight-distance problem combined installation of flashing beacon signs on hazardous horizontal curves; required inclusion of high-mounted, center rear brake lights on new cars; and trainingfor new drivers on how to recognize and respond to hazardous sight-distance situations. The best solution to the drunk-driving problem combined 10 countermeasures, including highway, driver, and vehicle countermeasures.
