摘要
高速公路交通事件的有效检测对保证交通安全、提高运输效率具有重大的经济效益和社会效益。文章首先对高速公路交通事件进行了种类划分,分别分析了常发性交通事件和偶发性交通事件对交通流的影响。采用交通仿真软件TSIS(traffic software integration systems)获取研究所需的数据,研究和分析如何进行交通事件检测算法的参数选择。通过对仿真数据的分析,发现以车辆占有率作为交通事件的检测参数更为合理。
The cffeefive detection of motorway traffic incidents has great economic benefits and social benefits in ensuring traffic safety and improving transportation efficiency. Motorway traffic incidents were categorized. The influences of recurring traffic incidents and non-recurring traffic incidents on traffic flow were analysed. The traffic simulation software traffic software, integration systems （TSIS）, was adopted to obtain relevant data to determine parameters of traffic incident detection. The simulation results indicate that it is more reasonable to choose the lane occupancy rate as detec- tion parameter of traffic incidents.
