In order to follow up the indicative spirit of developing state-level virtual simulation experimental platform under the outline of the national medium and long term educational reform and development, Chang’an University increased the investment for virtual experiments on the basis of current material foundation, and constructed virtual experimental platform with the background of traffic information and control. This paper states intension and requirement of the virtual experiment, framework and implementation method. Test for more than one year showed that the platform has run well with the ratio of 89.1 percent of virtual experiments to traditional experiments, and has been acclaimed by students and teachers.
