Research on Safety Evaluation of Three-dimensional Composite Channels based on Simulated Driving
This study proposes a technology based on simulated driving for safety evaluation of high-level three-dimensional composite channels.Firstly,three-dimensional modeling and parameterized design of the composite channel are realized,including the geometric form and traffic organization information of the main road section,interchanges,and their connecting sections.Then,combined with simulation driving technology,driver behavior characteristic data is obtained by simulating different driving behaviors and vehicle types of scenarios.Based on these data,objective evaluation and visual display of the road safety of composite channels can be achieved.Finally,the effectiveness and feasibility of this method are verified through a series of experiments.The research results indicate that the technology based on simulated driving has important application value in the safety evaluation of high-level three-dimensional composite channels,and can provide scientific basis and decision support for designers.This study has important theoretical and practical significance for expressway design and traffic safety management.
