基于人、车、路三维互动仿真技术,研究并开发了道路交通标志三维虚拟仿真评价系统,能再现实际道路交通标志的视认性和设置效果,通过主观评价和客观测试相结合的模拟评价方法,达到对交通标志系统进行优化改造的目的。该系统主要包括:驾驶员功能模块、车辆模型生成及类型选取模块和三维路网及场景构建模块。解决了评价交通标志系统时所存在的静态测试不足和动态测试工作繁重等问题,为道路交通标志系统的前期设计和后期优化改造等工作提供了直观、可靠的在线仿真分析平台。
Based on the three-dimensional interactive simulation technology of people, vehicles and roads, the three-dimensional virtual simulation evaluation system of road traffic signs is researched and developed. The visual recognition and setting effects of the actual road traffic signs can be reproduced. Through the combination of subjective evaluation and objective test, , To achieve the purpose of optimizing the traffic sign system. The system includes: driver function module, vehicle model generation and type selection module and three-dimensional road network and scene building module. It solves the problems of lack of static test and heavy workload of dynamic test in the evaluation of traffic sign system and provides an intuitive and reliable online simulation analysis platform for the preliminary design of road traffic sign system and the later optimization and transformation.
