Design and Development of Virtual Simulation Experiment for Active Control of Intelligent Freeway

针对高速公路实验教学难以现场开展,现有仿真软件交通流运行模型相对固定,难以有效支持交通流理论和应用的实验开展的现状,开发了《智慧高速主动管控虚拟仿真实验设计与建设》实验项目,基于Unity 3D构建轻量化交通流仿真平台,可复现不同天气环境下高速公路“主线+出入口匝道”交通流运行场景;学生可通过模型调参观察交通流运行特性,设置并评价高速公路主动管控策略,也可开发个性化交通流模型。该实验可帮助学生实现知识点的融会贯通,引导学生探索学科前沿,提高创新实践能力。

In view of the situation that freeway experiments are difficult to carry out on site,the existing traffic flow models are relatively mixed,which is difficult to effectively support the experiments of traffic flow theory and application,the project of“Virtual Simulation Experiment for Intelligent Freeway”is developed,which is based on Unity 3D to build a lightweight traffic flow simulation platform to reproduce the traffic flow operation scenario of“main line+entrance/exit ramp”under different weather conditions;students can observe the traffic flow operation characteristics through model tuning,and evaluate the active control strategy on freeway.Students can also develop personalized traffic flow models.The experiment helps students integrate the knowledge points,and guides them to explore the frontiers of the discipline,improve their innovation and practical ability.
