Analysis of Vehicle Trajectory on the Tunnel Entrance and Exit in the Large Longitudinal Slope Based on Driving Simulation

摘要

This paper investigates the vehicle trajectory characteristics of tunnel entrance and exit zone in the large longitudinal slope. The vehicle trajectory change rule of tunnel sections were concluded according to the collected operation parameters of 10 vehicle drivers by using eight (8) DOF driving simulator simulate tunnel sections in the long and steep downgrade. A regression was established model of the vehicle trajectory of the tunnel entrance and exit based on statistical methods.
