Abstract

Abstract

In order to study the prediction of operating speed on microsection for road safety evaluation, the driver's safety perception factor sets for third-class highway were determined, 3-D simulation model including 15 sections was built by using MultiGen Creator software, and the virtual simulation system was developed by using Vega.The perception evaluation tests with 53 drivers were carried out in three-channel cylinder projection system.Based on the analysis of 795 groups test data, the evaluation model including horizontal curve radius, longitudinal gradient and sight distance for third-class highway was presented by means of fuzzy statistics method.Computation result shows that the mean nearnesses between simulation tests and road tests of the individual evaluation levels on safety perception factors are 0.63, 0.74 and 0.70 respectively.So virtual simulation test is an effective means for the prediction of operating speed.
