面对我国城市群地区交通系统快速建设的现象，遵循“理论与实证分析相结合、多尺度分析相结合、定性与定量分析相结合、共性与个性分析相结合”的总体思路，综合运用交通地理学、交通运输工程学、城市地理学和区域经济学等多学科领域的技术方法和思想，以我国城市群地区的交通系统为研究对象，分析交通组织的动力机制，探讨交通系统与空间经济的互动关系，构建系统动力模型、空间效应评价模型、时空数据模型等系列模型，精准模拟城市群地区交通组织的动力系统和空间效应，标定其关键参数的阈值范畴。在此基础上，科学归纳城市群地区交通网络的演化阶段、交通服务圈的组织模式以及交通经济带的发展模式，提出城市群地区协同式交通组织的技术方法。预期成果包括研究报告、学术论文和著作，可为我国“快速城镇化背景下的城市群地区空间组织优化与空间效率提升”提供理论方法，既有助于缓解城市群地区的交通压力，又能引导城市群地区朝着合理的方向发展。

Nowadays, metropolitan areas are becoming more and more important and getting continuous development as the main form of new urbanization in China. Transportation systems are also developing rapidly as an important support for the metropolitan areas. Under this background, the research on the collaborative development mode of transportation systems is of great significance for the sustainable development of metropolitan areas. Following the general idea of "combination of theoretical and empirical studies, multiple scales, qualitative and quantitative analyses, as well as similarities and differences ", this research intends to explore the organizational mechanism and spatial effects of the transportation systems in metropolitan areas. First of all, based on the theories and methods of transportation geography, transportation engineering, urban geography and regional economics etc., the organizational mechanism of transportation systems and interactive relationships between the transportation systems and spatial economy will be explored. Secondly, the system dynamic model, spatial effects evaluation model and spatio-temporal data model will be adopted to facilitate accurate simulations of the dynamic system and spatial effects of transportation organization in metropolitan areas. Meanwhile, the threshold of key scientific parameters will be calibrated. Finally, the research will produce a scientific summary of the evolutionary trajectories of transportation networks, the organizational patterns of traffic service circles as well as the development mode of traffic economic belt and propose a technical method of coordinated transportation organization in metropolitan areas. Relying on the research above, reports, papers and scholarly monographs which can provide theoretical foundations for "spatial organization optimization and spatial efficiency improvement of metropolitan areas in the context of rapid urbanization" will be published. The research will not only help to relieve the traffic pressure, but also can provide guidance for the reasonable development of metropolitan areas.
