Jingtong Expressway Evening Peak Tidal Lane Options

As urbanization continues to advance, the growing size of the cities of Beijing,but the core functional areas concentrated in the main urban areas, residential areas,but the suburban counties develop relations this imbalance leads to morning and evening peak period "tidal" traffic phenomenon particularly serious, and this is one of the important factors in this project sources. Beijing Jing Tong Expressway as a typical representative of one section of the tidal phenomenon, studied tidal driveway construction and operation of the program is innovative and forward-looking.Tidal asymmetric traffic lane as an important means to solve, has been widely used at home and abroad, however, apply it with no precedent urban freeway or highway. In the study of Beijing-lane expressway tidal process, traffic and driving speed during the evening peak investigation to analyze the set tidal lane road traffic by calculating the distribution coefficient and the average vehicle in the form of speed,while establishing a variable lane mathematical model to optimize the allocation, by mathematical methods to prove the reasonableness of the lane assignment. Tidal lane scheme selected long and short two sections contrast, its important to analyze each node, building programs, entrances, section plan, technical and economic indicators, a comprehensive analysis of the risks and problems of two programs.Operational security programs is extremely important element ofJ ing Tong Expressway tidal lane project. On the daily management requires the use of standardized processes to manage start preparation, startup, shutdown, and other steps tidal lane, so that the whole process run smoothly and efficiently. In the emergency management organization first established to protect the establishment and implementation of group coordination group, followed by the development of solutions for all types of emergencies that may occur, whether it is to ensure that accidents or other emergencies are able to calmly deal with, fast processing.Through the Beijing-lane freeway tidal discussion and research, not just to solve the problem of building and operating its own terms, while survey data traffic and driving speed can be used as basic data as a basis for decision making. Moreover, lots of complex traffic and road traffic organization the right to use the processing method,and the principles of emergency rescue and management can also provide a reference for other related similar set tidal lane city roads.
