The Methods of Analysis and Calculation of the Influence of the Heavy Vehicles on the Driver in the Rear Vehicle

This paper analyzes the potential psychological and physiological effects of heavy vehicles on the driver in the rear vehicle at basic freeway segments. First, we define the influence of the heavy vehicle on the driver in the rear vehicle. Then we studied the basic features of the influence on drivers through SP surveys. Finally, we used binomial logistic regression models and fuzzy logic to screen out significant factors and construct the calculation model for the heavy vehicle influence, respectively. We found that the influence of heavy vehicles can change the driving behavior of the rear vehicle. Moreover, passenger car drivers are more sensitive to the influence than heavy vehicle drivers. The proposed model can calculate the influence degree of the heavy vehicle quantitatively, where the factors vary for passenger car and heavy vehicle drivers.
