中文摘要: 层次性作为公交网络的基本系统特性之一,在国内外的规划实践中已得到了广泛应用。实践证明,层次性有助于完善公交系统的功能和提高效率,是公交网络优化的重要方式。针对现有公交网络分层规划的工程实践缺乏必要的基础理论支持这一现实背景,本项目首先通过案例搜集与基础数据采集,研究公交网络的复杂拓扑性质,进行公交网络层次性的拓扑实证;其次,引入复杂网络演化规则的设计理念,构建公交网络的演化模型,开展数值模拟实验,研究公交网络层次性的形成机理及其与网络性能的演化关系;再者,通过交通调查研究多层次公交网络中的交通行为,构建多层次公交网络客流分配模型;在此基础上,研究如何确定公交网络层次的合理级配关系,并进一步研究基于层次性的公交网络布局优化方法。研究成果将深化对公交网络这一复杂系统的理解,为多层次公交网络的优化设计提供理论支持、分析方法和实用工具。

英文摘要: As a basic phenomenon of transit network, hierarchy property has been widely used in the bus network planning practice at home and abroad. Practice has proved that hierarchy property will improve the function of transit system and its efficiency. It is an important way for the optimization of transit network. To solve the problem of lacking theory basis in the existing transit network level planning method, the research will study the complex characteristics of transit network and prove its hierarchy property on the basis of investigation. According to the evolution laws of complex network, the transit network evolution model will be established. The formation mechanism of transit network hierarchy property and its relationship with network performance will be studied on the basis of numerical simulation experiments. On the basis of passengers' behavior investigation, the hierarchical transit passenger flow assignment model will be studied. Then, the research will analyze the optimal grade proportion of transit network and put forward its optimization method. This research will help us to understand complex system characteristics of transit network and provide theory basis and practical method for its planning and optimization.
