【摘要】：随着汽车保有量的不断增加,刺激了高速公路里程的显著提升,为运输行业的蓬勃发展提供了良好的机会。高速公路具有高效、快捷、便利、封闭等特点,成为人们长途出行的重要选择。高速公路网的建设结构与经济发展密不可分,一旦重要节点及路段遭遇自然灾害或者重大交通事故导致阻断,将会对路网造成大规模瘫痪,对人民生命财产安全带来巨大威胁,所以对于路网的结构特征从不同的角度进行评价是十分必要的。高速公路网具有结构复杂、节点多样、多重复杂性融合等特征,因此可以基于复杂网络理论对高速公路网进行研究。首先,本文介绍了复杂网络及图论的基本概念,阐述了复杂网络中的基本统计指标,将国内外学者研究成果进行归纳梳理,为后续研究提供理论依据。其次,本文根据网络元素的设定方式选取Space L模型为建模方式,从微观、宏观两种表达粒度,对高速公路网建立广义网络拓扑模型。广义网络拓扑模型分为市域网络模型及全局网络模型,市域网络模型以高速收费站为节点,以收费站间的高速路段为边;全局网络模型以城市为节点,以城市间是否直接连通为边,并且针对建立的广义网路拓扑模型从微观、宏观两个层面分析静态网络的结构特征。再次,考虑道路里程、通行能力等功能属性对路网结构的影响,定义高速公路网络的连通性测度、均衡性测度和抗毁性测度,构建了市域网络和全局网络结构特征动态评价的指标体系。最后,以路网结构动态评价指标体系作为理论依据,在ArcGIS二次开发的基础上,基于java、jsp和java script等编程语言,利用My Eclipse作为系统开发工具,采用了 B/S网络架构模式,研发路网结构动态评价系统并利用系统计算相应评价指标。分别从正常交通流状态和发生阻断事件两方面,研究动态参数对路网结构的连通性、均衡性、抗毁性等性能的影响,实现路网结构动态评价,验证了评价指标的适用性。最后根据分析结果提出改进建议及措施,实现将高速公路网结构动态评价系统应用于实践的研究目的。
[Abstract]:With the increasing number of vehicles, it stimulates the highway mileage to improve significantly, and provides a good opportunity for the development of the transportation industry. Expressway has the characteristics of high efficiency, fast, convenient and close, so it has become an important choice for people to travel long distances. The construction structure of the highway network is closely related to the economic development. Once the important nodes and sections are blocked by natural disasters or major traffic accidents, the road network will be paralyzed on a large scale and the safety of people's lives and property will be greatly threatened. Therefore, it is necessary to evaluate the structural characteristics of road network from different angles. The expressway network has the characteristics of complex structure, diversity of nodes and fusion of multiple complexity, so it can be studied based on the theory of complex network. Firstly, this paper introduces the basic concepts of complex network and graph theory, expounds the basic statistical indicators of complex network, summarizes the research results of domestic and foreign scholars, and provides the theoretical basis for further research. Secondly, according to the setting mode of network elements, this paper selects Space L model as the modeling method, and establishes the generalized network topology model for the expressway network from the micro and macro representation granularity. The generalized network topology model is divided into city network model and global network model. The local network model takes high speed toll station as the node and takes the high-speed section of the toll station as the edge; the global network model takes the city as the node, and the global network model takes the city as the node. Taking whether the cities are directly connected or not, and aiming at the established generalized network topology model, the structural characteristics of the static network are analyzed from the micro and macro aspects. Thirdly, considering the influence of road mileage and capacity on the road network structure, the paper defines the connectivity measure, equilibrium measure and invulnerability measure of highway network. The index system of dynamic evaluation of local network and global network structure is constructed. Finally, based on the dynamic evaluation index system of road network structure, on the basis of the second development of ArcGIS, and based on the programming languages such as javajsp and java script, this paper uses my Eclipse as the system development tool, and adopts the B / S network architecture model. The dynamic evaluation system of road network structure is developed and the corresponding evaluation index is calculated by using the system. The effects of dynamic parameters on connectivity, equilibrium and survivability of road network structure are studied from two aspects of normal traffic flow state and blocking event respectively. The dynamic evaluation of road network structure is realized, and the applicability of evaluation index is verified. Finally, according to the analysis results, some suggestions and measures are put forward to realize the research purpose of applying the dynamic evaluation system of highway network structure to practice.
