摘要:
研究高速公路紧急事件下的交通流特征,对于减少高速公路拥挤、降低二次事故、提高通行能力有重要的作用。由于高速公路紧急事件具有偶然性、不可预测性的特点,在实际调研中往往难以及时捕捉到交通事件的相应信息,导致源数据不足进而影响研究的进行。本文通过微观仿真手段,结合实地调研获得紧急状态下车辆运行参数,在AIMSUN仿真环境下加载紧急事件,建立了高速公路微观路段的仿真模型。并将路段平均车速、密度、最大排队长度等作为指标,定量计算紧急事件下各种交通参数的变化规律。最后与调研结果进行了对比,表明仿真结果与实际情况较为一致。
Abstract:
The study on highway traffic flow characteristics in condition of traffic incidents plays an important role in eliminating traffic clog, reducing secondary crashes, and improving highway capacity. However, most of the traffic incidents are occasional and unpredictable, and it is difficult to capture the information and data of traffic incidents, so the studies of traffic flow characteristics in this condition would be very difficult. Moreover, current existing studies on highway traffic flow characteristics based on simulation didnt take traffic incidences as objects. Therefore, in this article, a new study method based on simulation was presented. Considering the data of onsite investigations, the microscopic simulation model of highway sections was built by AIMSUN Microsimulator Software, and the traffic incidents were merged into the model. Then the visual and quantificational description of traffic flow characteristics were given in the form of figures with traffic parameters such as average speed, density, and maximum length of the queue. Finally, the simulation results were compared with investigation results, and the comparative results showed that they had great consistency.
