【摘要】 中小城市在我国城市中占据重要地位,薄弱的路网基础与混杂的交通流构成使其交通特性不同于国外城市和国内大城市。随着我国经济的发展,中小城市交通拥堵问题愈演愈烈,研究适应于我国中小城市的交通控制策略与微观交通仿真模型,对我国社会、经济与环境都具有重要和深远的意义。本文在查阅文献与实地调研的基础上,对中小城市中动态、静态交通设施和各类交通对象的特性进行分析与总结,基于TransModeler建立路网描述模块、交通需求模块和车辆行驶模块,并结合常用的控制策略,分析适应性,建立交通控制方案生成模块；最后综合考虑环境、经济、交通的影响,提出中小城市交通评价体系。具体研究工作如下：1)对我国中小城市的动态、静态交通设施,行人流、非机动车流、机动车流的组成、特性与成因进行了系统性的分析、梳理和总结,为微观交通仿真模型的建立提供了理论依据。2)根据中小城市的道路交通环境、车流特点、经济状况等作用因素,分析了交通系统管理、交通需求管理、单路口定时控制、干线协调控制以及感应控制等国内外城市常用的具体交通改善技术在我国中小城市的适用性,得到具有中小城市特点的交通控制策略。3)考量与筛选经济、环境、交通等多方面的指标,对交叉口通行效率和公交服务系统中的重点单项指标的内容、计算公式等进行详细说明,建立起适合中小城市的交通评价体系。4)在理论分析的基础上,利用TransModeler软件建立具有中小城市特点的微观交通仿真模型。基于某城市实际调研数据设计的潮汐交通协调控制系统的仿真实验,验证了本文所建微观交通仿真模型的有效性和优越性。更多还原

【Abstract】 Small and medium-sized cities occupy an important position in China. Weak road network and the mixed traffic flow make its traffic characteristics different from foreign cities and big cities at home. With the development of China’s economy, traffic congestion problems in small and medium-sized cities are growing more and more serious. Studying suitable traffic control strategy and microscopic traffic simulation model have important and far-reaching significance for China’s society, economy and environment.Based on the literature review and field research, the characteristics of dynamic and static transport facilities as well as all transport objects in small and medium-sized cities were analyzed and summarized. Road network description module, traffic demand module and vehicle driving module were established based on TransModeler; after analyzing common traffic control strategy and its adaptability, traffic control program module was built; finally after comprehensive consideration of environmental, economic and traffic effects, traffic evaluation system of small and medium-sized cities was proposed. The main work of this paper was as follows:(Ⅰ) The composition, characteristics and causes of dynamic and static transport facilities, pedestrian flow, non-motor vehicle flow, vehicle flow in small and medium-sized cities were systematic analyzed and summarized. It provided a theoretical basis for establishing microscopic traffic simulation model.(Ⅱ) Based on the role of traffic environment, traffic characteristics, economic conditions and other factors in small and medium-sized cities of the road, the applicability of common traffic improvement techniques such as transportation system management, transportation demand management, pre-timing control of single intersection, coordinated control and adaptive control was analyzed, and proper traffic control strategies were generated.(Ⅲ) After considering and selecting economic, environmental, transportation evaluation indices, proper traffic evaluation system was built for small and medium-sized cities. Then the content and formula of individual focus index were explained.(IV) On the basis of theoretical analysis, microscopic traffic simulation model that has characteristics of small and medium-sized cities was built by using TransModeler software. Based on the real survey data, coordinated control system of some city for tide traffic was designed, and simulation test verified the effectiveness and superiority of this microscopic traffic simulation model.更多还原
