A Users' Guide to Positive Guidance in Highway Control

Abstract

Positive Guidance is an approach to enhance the safety and operational efficiency of hazardous locations. This approach joins the highway engineering and human factors technologies to produce an information system matched to the characteristics of the location and the attributes of drivers. The Users' Guide to Positive Guidance is used to both analyze the location and develop the most effective solution. The Guide provides a procedure consisting of six major functions: Data collection at problem locations; problem specification; definition of driver performance factors; definition of information system requirements; determination of positive guidance information; and evaluation.
