【摘要】：货车限行措施能够有效提高高速公路的通行能力,缓解交通拥堵。通过建立微观交通仿真模型,分析货车限行措施及货车事故对高速公路交通状态的影响。基于京藏高速公路的实地调研数据标定模型参数,设定5个不同的货车限行时间段仿真方案,并模拟货车事故发生后的疏散情况。结果表明货车禁行最合适的时间段是7:00~19:00,小客车旅行时间降低了10%,且货车在8:00之前完成疏散;其他方案则会导致货车滞留,影响第二天早高峰的交通状态;货车事故会导致车辆在高速路上大范围排队滞留。
[Abstract]:Van traffic restriction measures can effectively improve the capacity of freeway and alleviate traffic congestion. By establishing microscopic traffic simulation model, this paper analyzes the influence of freight car traffic restriction measures and truck accidents on the traffic state of freeway. Based on the field investigation data of Beijing-Tibet Expressway, the model parameters are calibrated, and five different simulation schemes are set up, and the evacuation situation after the accident is simulated. The results show that the most suitable time period is 7: 00 to 19: 00, the travel time of minibus is reduced by 10 percent, and the truck is evacuated before 8:00, other schemes will cause the truck to be stranded, which will affect the traffic state of the morning rush hour the next day. Truck accidents can lead to large queues on highways.
