To study the relationship between deceleration and facility setting mode of expressway reconstruction area, selecting factors to be independent variables such as the number of traffic signs and the distance between continuous construction area. Four different virtual scenes are built, and 30 different experienced drivers are organized to finish the simulated driving test to obtain data such as speed and acceleration, and adapt questionnaires to obtain.According to the data, obtaining the influence of drivers in warned area under different variables. The result shows that the longer the distance between construction areas, the higher the instantaneous speed and the speed of deceleration starting point. The setting mode has a greater influence on the average deceleration during the decelerating period, and it become lower when the step-by-step speed limit is set. Drivers experience has significant influence on deceleration starting point, experienced drivers tend to slow down beforehand. The results above provided evidences and references for the setting mode of facilities and protecting drivers in expressway reconstruction area.
