摘要
提出了一种基于模拟驾驶的技术,用于高等级立体复合通道的安全评价。首先,实现对复合通道的三维建模和参数化设计,包括主线路段、互通立交及其连接段的几何形态和交通组织信息;然后,结合模拟驾驶技术,通过模拟不同驾驶行为和车辆类型的情景,获取驾驶人的行为特征数据,基于这些数据,可以实现对复合通道的道路安全性进行客观评价和可视化展示;最后,通过一系列试验验证了该方法的有效性和可行性。研究结果表明,基于模拟驾驶的技术在高等级立体复合通道的安全评价中具有重要的应用价值,可为设计者提供科学依据和决策支持。本研究对于高速公路设计和交通安全管理具有重要的理论和实践意义。
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.
