【摘要】：当高速公路有交通事故发生时,怎样进行科学高效的决策,对事故路段的车辆进行有序的疏导,最大限度的降低车辆的延误,已成为高速公路运营管理部门亟需解决的关键问题。现有的交通疏导方式主要是通过可变情报板、交通广播等信息发布设施向车辆发布诱导信息,或是路政交警等人员对事故现场的车辆进行疏导,但是这些方法无论是从覆盖率或效率等方面来说,都有一定的局限性。论文针对现有的高速公路事故路段交通疏导方法的不足,在现有的智能手机及3G/4G网络的迅速发展与广泛普及的基础上,结合事故信息、路段基本信息、路网拓扑结构信息、历史交通流数据信息以及实时的交通流信息及通行能力等,提出一种新型的基于点对点导航的高速公路事故路段交通疏导方法。基于点对点导航的高速公路事故路段交通疏导方法以手机APP/车载GPS导航为载体,将针对事故的交通疏导策略点对点的发布给事故路段的车辆,实现对车辆点对点的指挥。论文分析了不同类型车辆的转弯半径、排队长度、车型比例、实时通行能力及实时交通流量对疏导策略的影响,应急调度指挥中心针对不同的事故信息,生成相应的的疏导策略,发布给受事故影响的车辆。基于点对点导航的高速公路事故路段交通疏导方法以车辆的延误时间最小为原则,同时考虑了驾驶员的心理因素,做到兼顾公平性,分析了事故造成道路阻断情况下车辆的疏导模型,并制定不同模型下的疏导策略,最终进行比选,选出最优的交通疏导策略。论文的特色是智能化的疏导方法替代现有的疏导方法。基于点对点导航的交通疏导方案由计算机确定,综合考虑各种因素,做出最优的交通疏导策略,模块化有序的疏导车辆,减少车辆之间无序状态下的冲突,降低时间延误,更加智能化,且策略的生成由计算机后台运行完成,更加高效;对于车辆运行时间的计算或交通警戒设备的计算更加精细,准确性高。
[Abstract]:When there are traffic accidents on the freeway, how to make scientific and efficient decision, how to arrange the vehicles in the accident section in order to minimize the delay of the vehicles, It has become a key problem that the highway operation management department urgently needs to solve. The existing traffic dredging methods mainly through the variable information board, traffic broadcasting and other information distribution facilities to vehicles to release guidance information, Or road traffic police and other personnel to carry out the vehicles at the scene of the accident, but these methods are no matter in terms of coverage or efficiency. The thesis aims at the deficiency of the existing methods of freeway traffic diversion, based on the rapid development and popularization of the existing smart phone and 3G/4G network, combines the accident information, the road section basic information, Network topology information, historical traffic flow data information, real-time traffic flow information and traffic capacity, etc. In this paper, a new method of freeway traffic diversion based on point-to-point navigation is proposed. The method based on point-to-point navigation is based on mobile phone APP/ vehicle-borne GPS navigation. The point-to-point traffic diversion strategy for the accident is issued to the vehicle in the accident section, and the vehicle point-to-point command is realized. The turning radius, queue length and vehicle model ratio of different types of vehicles are analyzed in this paper. The influence of real time traffic capacity and real time traffic flow on the dredging strategy. The emergency dispatch command center generates the corresponding dredging strategy according to different accident information. Based on point-to-point navigation, the traffic diversion method of highway accident sections is based on the principle of minimum delay time of vehicles, and the psychological factors of drivers are taken into account, so that fairness can be taken into account. This paper analyzes the vehicle grooming model under the condition of road blocking caused by accident, and formulates the grooming strategy under different models, and finally makes comparison and selection. The characteristic of this paper is that the intelligent grooming method replaces the existing grooming method. The traffic grooming scheme based on point-to-point navigation is determined by the computer and all kinds of factors are considered synthetically. Making the optimal traffic diversion strategy, modularizing orderly grooming vehicle, reducing the conflict under the disorder state between the vehicles, reducing the time delay, more intelligent, and the generation of the strategy is completed by the computer backstage operation, more efficient; The calculation of vehicle running time or traffic warning equipment is more precise and accurate.
