【摘要】：貨車限行措施能夠有效提高高速公路的通行能力,緩解交通擁堵。通過(guò)建立微觀交通仿真模型,分析貨車限行措施及貨車事故對(duì)高速公路交通狀態(tài)的影響�；诰┎馗咚俟返膶�(shí)地調(diào)研數(shù)據(jù)標(biāo)定模型參數(shù),設(shè)定5個(gè)不同的貨車限行時(shí)間段仿真方案,并模擬貨車事故發(fā)生后的疏散情況。結(jié)果表明貨車禁行最合適的時(shí)間段是7:00~19:00,小客車旅行時(shí)間降低了10%,且貨車在8:00之前完成疏散;其他方案則會(huì)導(dǎo)致貨車滯留,影響第二天早高峰的交通狀態(tài);貨車事故會(huì)導(dǎo)致車輛在高速路上大范圍排隊(duì)滯留。
[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.
