In the same road conditions and similar traffic environments, vehicle speeds vary although drivers are operating the same types of vehicles with identical performances: some of the actual speeds are higher than the design speed of the road, and some are lower. The deep reason behind this problem is this: the desired speed established by the different individuals varies. Based on the analysis of the forming process and factors influencing driver's desired speed, single-factor simulation experiments were designed, and a three-dimensional scene model was established using a virtual scene generation system. Sixteen subjects were selected to participate in the experiments, and a statistical analysis was made using the SPSS software base on experiment data. Analysis of results reveals that lane number, lane width, and shoulder width influence the desired speed; the relationship between desired speed and lane numbers, lane width, the shoulder width is respectively regressed. Finally, based on the results of the desired speed simulation experiment, an integrated model has been built, and guidelines are offered for assessing the impact of lane number, lane width, shoulder width, driver conditions and vehicle conditions, explaining how to select a correction coefficient.
