中文摘要: 地面交通的网络空间效应及作用机理等问题是交通运输地理学、交通规划学等学科的重点交叉研究领域。地面交通快速化和网络化发展趋势使得其对区域空间结构演化产生重要影响。要求以更加精细和准确的角度来刻画地面高速交通的空间效应和空间组织绩效。现有研究在交通模式集合、空间效应精细化方面研究尚有待深入,本研究依托高速公路及高速铁路基础网络及运行数据,在可达性等传统空间分析方法基础上,以方式分担、需求差异、运输价格、容量频次、安全系数等运输组织和交通行为特征差异数据为补充,建立整合高速公路与高速铁路两种方式的空间效应测度模型,从动态(高速交通产生前后)和静态(特定时间截面)两个视角对中国地面高速交通网络的结构特征、运行效率、空间效应测度等关键问题进行量化表达和系统研究,力图建立起结构清晰、反馈明确的模型方法集,以期完善交通运输地理空间分析研究方法体系,深化高速交通网络与区域社会经济发展的互动机理认识。

英文摘要: Research on spatial effect and mechanism analysis of surface transportation network is a key cross field of transportation geography and transportation planning study.The high-speed and networked development tendency of surface transportation network makes it have an important impact on regional spatial structure evolution.More precise and accurate insight is required to depict the space effect and space organization performance of surface transportation network. Transportation pattern integration and spatial effect refine remains to be further in current research,this study based on highway and high speed railway foundation network and operation data and traditional space analysis method like accessibility measure, transport organization and traffic behavior characteristics difference factors like traffic mode split, demand difference, transportation price,capacity frequency, safety coefficient are added for supplements, make a integration spatial effect measure model to evaluate the highway and high speed railway utility synthetically.Make a quantitative expression and system research on the key issues of china's surface high-speed transportation network,such as structure characteristics,operation efficiency,spatial effect measure description from dynamic (before and after high-speed transportation produce) an
