Abstract

Abstract: Currently, when static edge rate is used for vehicle speed control, cycle length of edge rate period and total length of pavement corresponding to all vehicle speeds are fixed, so it is not well-targeted and achieves no obvious effects in speed reduction. In order to make up for this defect, a dynamic speed control edge rate model for tunnel segment was established with minimum vehicle speed dispersion as objective function based on the positive correlation between accident rate and vehicle speed dispersion. Then, speed control system of dynamic edge rate was installed in central section of long tunnel on expressways for intelligent linkage studies between dynamic edge rate and traffic flow. Finally, vehicle speeds with or without control system of dynamic edge rate were compared and analyzed. The results show that speed control system based on dynamic edge rate model for tunnel sections can effectively control it with overspeed ratio decreasing by 16.69%, 85^th percentile speed, average speed and speed standard deviation decrease by 6.67%, 7.96% and 13.45% respectively, and its control effect is more remarkable than that of static edge rate.

Key words: long tunnel, dynamic edge rate, dynamic speed control, vehicle speed dispersion, edge rate optimization model
