【摘要】：近年来,我国高速公路货车比例不断增长,货车不断向着大型化、重载化的方向发展,货车对于高速公路运行效率及交通安全方面的影响日益严重。针对这一问题,目前常采用客货分道行驶静态控制方法进行管理,其是基于道路交通的历史数据对客货车道进行划分,当车道划分完成后基本不会随交通流变化而变化,这种不是基于需求响应互相影响的控制方式仅适用于交通流简单的情况。但在实际道路中,平常日、周末和节假日等不同时段内的交通量和交通组成差别大,甚至在同一天内的白天和晚上,交通组成差异也较明显,随着交通量的逐年快速增加和交通组成的日益复杂,客货分道行驶静态控制将与交通需求不适应。为此,本文提出高速公路客货分道行驶动态控制管理方法,以解决客货分离行驶静态管理方法的缺陷,提高道路的通行能力。本文首先在研究国内外客货分离行驶静态控制管理方法的基础上,对高速公路客货分离行驶静态控制方法和动态控制方法进行对比,提出静态控制存在的问题以及动态控制的优势。其次在分析客货分道行驶动态控制车道划分原则的基础上,对动态客货分道划分的基本参数进行研究,提出了基于需求车道数的双向六车道、八车道以及十车道的车道划分方法。从道路条件、交通条件、天气条件和人的感受四方面分析了高速公路客货分道行驶动态控制速度的影响因素,提出了基于模糊综合评价法和模糊推理理论针的动态控制限速模型。最后,通过借鉴国内外城市潮汐车道控制的实践以及相关研究成果,提出了适用于高速公路客货分道行驶动态控制管理的信息采集技术、信息处理技术和信息发布技术,为高速公路客货分道行驶动态控制管理方法的有效实施提供保障。
[Abstract]:In recent years, the proportion of freeway freight cars in China has been increasing, and the freight cars have been developing towards the direction of large-scale and heavy loading. The impact of freight cars on the efficiency of expressway operation and traffic safety is becoming increasingly serious. In order to solve this problem, the static control method of passenger and cargo traffic is often used to manage, which is based on the historical data of road traffic to divide the lanes of vans and trucks, which will not change with the change of traffic flow after the completion of lane division. This control method, which is not based on the interaction of demand response, is only suitable for simple traffic flow situations. However, in the actual road, the traffic volume and traffic composition vary greatly in different periods such as ordinary days, weekends and holidays, even during the day and evening of the same day. With the rapid increase of traffic volume and the increasing complexity of traffic composition, the static control of passenger and cargo traffic will not adapt to the traffic demand. For this reason, this paper puts forward the method of dynamic control and management of highway passenger and cargo traffic separation, in order to solve the defects of the static management method of passenger and cargo separation and improve the traffic capacity of the road. Firstly, on the basis of studying the static control methods of passenger and cargo separate driving at home and abroad, this paper compares the static control method and dynamic control method of highway passenger and cargo separation. The problems existing in static control and the advantages of dynamic control are put forward. Secondly, on the basis of analyzing the principle of dynamic control lane division of passenger and cargo traffic, the basic parameters of dynamic passenger and cargo lane division are studied, and the bidirectional six lanes based on the number of required lanes are put forward. Eight lane and ten lane division method. From four aspects of road condition, traffic condition, weather condition and people's feeling, this paper analyzes the influencing factors of dynamic control speed of highway passenger and freight separation. A speed limiting model for dynamic control based on fuzzy comprehensive evaluation method and fuzzy inference theory needle is proposed. Finally, through drawing lessons from the practice of urban tidal lane control at home and abroad and related research results, the paper puts forward the information collection technology, information processing technology and information release technology, which are suitable for the dynamic control management of highway passenger and cargo traffic. It provides a guarantee for the effective implementation of the dynamic control management method of highway passenger and cargo traffic.
