【摘要】：随着近几年我国进出口贸易量的迅速增长,港口进出口货物量激增,使得港口集疏运系统也面临巨大的压力。对集疏运系统进行改造优化以提高其运行效率,从而提高港口运行效率,成为很多港口所面临迫切需要解决的首要问题。在这些问题中,一些闸口、卡口等出入口,如港口保税物流园区出入口作为进出保税物流园区的咽喉位置,更是发生交通拥堵的瓶颈之一,特别是出口系统,其运营过程在高峰期存在的交通拥堵现象,成为制约港口集疏运系统必须解决的首要问题。基于此,本文对保税物流园区出入口尤其是出口系统进行优化,主要内容为:(1)保税物流园区出入口系统分析:在讨论系统基本要素、环境因素和交通特点等的基础上,寻找系统问题所在,讨论分析了区域的机动车行驶动特性,确定了各个子系统和相关模型参数,为建立出口CAM提供可能。(2)保税物流园区出口CAM的建立:针对以大型货车为主,并有部分小型客车的港区交通流,采用交通流对称型双车道(symmetric two-lane Nagel-Schreckenberg,STNS)元胞自动机模型建立保税物流园区出口CAM,根据系统分析结果,定义各区域机动车行驶规则和各项参数,为仿真实验提供基础。(3)基于CAM的保税物流园区出口优化设计:针对天津港保税区已有交通问题和具体约束,提出关于出口卡口、交织区和交叉口的改造方案,应用已建立的CA模型进行仿真实验,综合考虑通行效率、通行时间、资金成本、系统匹配度四方面因素,建立出入口系统综合评价体系,通过对实验各项指标的系统评价,确定最优设计方案。(4)基于CAM的保税物流园区管理措施优化:针对天津港保税区出口交通流时空分布严重不均衡特性,应用信号灯在线调整、VSM等技术手段对交叉口、卡口的时空资源进行合理分配,通过CAM仿真确定高峰期、非高峰期的适用管理方案。
[Abstract]:With the rapid growth of China's import and export trade in recent years, the port import and export cargo volume has increased sharply, which makes the port transportation system also face great pressure.In order to improve the operation efficiency and improve the port operation efficiency, it is an urgent problem that many ports need to solve.Among these problems, some gate, bayonet and other entrances and exits, such as the entrance and exit of port bonded logistics park, as the throat position in and out of bonded logistics park, are also one of the bottlenecks of traffic jam, especially the export system.The traffic congestion in the peak period has become the most important problem which must be solved to restrict the port transportation system.Based on this, this paper optimizes the entrance and exit system of bonded logistics park, especially the export system. The main content is the analysis of import and export system of bonded logistics park. On the basis of discussing the basic elements of the system, environmental factors and traffic characteristics, etc.To find out the problem of the system, discuss and analyze the driving characteristics of the vehicle in the region, determine the parameters of each subsystem and relevant model, and provide the possibility of establishing export CAM. 2) the establishment of export CAM of bonded logistics park.And the traffic flow in port area of some minibuses is established by using the cellular automata model of symmetrical two-lane two-lane Nagel-Schreckenberg STNSS to establish the exit CAM of bonded logistics park. According to the results of system analysis, the driving rules and parameters of each region are defined.To provide the foundation for simulation experiment. (3) optimal design of bonded logistics park export based on CAM: aiming at the existing traffic problems and specific constraints in Tianjin Port bonded area, this paper puts forward the reconstruction scheme of exit bayonet, interlaced area and intersection.By using the established CA model to carry out the simulation experiment, the comprehensive evaluation system of the entrance and exit system is established by considering the four factors of the passage efficiency, the passage time, the cost of funds and the matching degree of the system, and through the systematic evaluation of each index of the experiment.To determine the optimal design scheme. (4) optimizing the management measures of bonded logistics park based on CAM: aiming at the serious imbalance of the spatial and temporal distribution of export traffic flow in Tianjin Port bonded area, applying the signal lights online adjustment and other technical means to intersections,Through CAM simulation, the suitable management scheme for peak and off-peak periods is determined.
