Abstract:

The paper aimed at the important technique problem of how to quantify theevaluation of quality in line design during road safety audit. Based onanalyzing the researches at home and abroad, and practice investigations,westructured the quantity evaluation model of line design quality in freeway,andhave found out the inherence contact between the cost of quantity evaluationmodel and accident rate per 100 million vehicle kilometers. The paper validatedthoroughly the adaptability and validity of the model. Finally it presents theevaluation standard of freeway line design.

Key words:

freeway; quality of line design; evaluation model; speed and trafficaccident rate
