Effectiveness of Alternative Skid Reduction Measures. Volume III. Users Manual

摘要

A computerized benefit-cost model is presented for use by state highway departments in the selection of accident-reduction countermeasures to be applied to investigated sites. The model has capability to evaluate both surface modifiction countermeasures, which increase frictional supply, and geometric and traffic control countermeasures, which reduce frictional demand. The model considers the effectiveness of each countermeasure under both wet- and dry-pavement conditions. The model logic is described briefly to familiarize the program user with the type of analysis performed. The information needed by state highway department to use the model as a decision-making tool is presented in detail. Such information includes input requirements, input formats, output formats and interpretation of analysis results.
