摘　　要：交通路网是连接不同经济主体,促进区域经济协调发展的重要基础设施。作为人文地理学和区域经济学研究领域的热点问题之一,在交通路网对社会经济的支撑和带动作用等方面已经积累了大量的研究成果。然而,现有研究聚焦于从区域路网的角度分析交通区位优势及其对经济社会发展的影响,较少考虑到不同等级公路在交通效率和通行能力方面的差异及其对区域经济的影响。文中研究了不同等级交通路网密度空间分布格局,提出了基于道路等级和道路密度的长三角区域公路交通协同指数构建方法。以长江三角地区41个城市的交通路网为例,验证文中提出的区域交通协同指数计算方法,并分析了交通协同指数和以GDP为代表的经济统计数据之间的相关性。结果表明,文中提出的区域交通协同指数计算方法可以较好揭示区域内的交通路网空间分布特征,指数计算结果与GDP数据之间呈现显著的正相关性,可以用来反映经济发展趋势。Traffic road network is an important infrastructure that connects different economic entities and promote the coordinated development of regional economies.As one of the hot spots in human geography and regional economics research area,the support and driving role of the traffic road network on the economy has accumulated lots of research results.However,the existing achievements mainly focus on the advantages of transportation location and its impact on economic and social development from the perspective of the overall regional road network.They failed to take into account the differences in traffic efficiency and capacity of different grades of roads and its impact on regional economy.This paper analyzed the spatial distribution characteristics of the road density with different grades and proposed the construction method of traffic coordination index model in the Yangtza River Delta based on road grade and road density.It takes the traffic road networks of 41 cities in the Yangtze River Delta as examples,verifies the calculation method of regional traffic coordination index proposed in this paper,and analyzes the correlation between the traffic coordination index and the economic statistics represented by GDP.And the results show that the calculation method of regional traffic coordination index proposed in this paper can better reveal the regional spatial distribution characteristics,and there is a positive correlation between the GDP data and the data calculated by the regional traffic coordination index model,which can be used to reflect economic development trends.
