Model predicting the operating speed of passenger car on mountain slope

At the present, the vehicle operation research on slope sections in mountainous area mainly use statistical analysis to describe the correlations between operating speed and road alignment, which could not explain the vehicle's driving risks with different dynamic characteristics on slope sections. Based on vehicle dynamic analysis, a basic operating speed of passenger car is achieved by the dynamic model, then the model amended by road factors is acquired to predict the operating speed. The operating speed of passenger car on some of slope sections were carried out by MATLAB programming and GUI visualization. The comparison of observation speed with operating one shows that the accuracy of operating speed of forecast model is higher, and has a good applicability.
