摘要
为探索土地利用紧凑性与城市交通拥堵之间的联系,以武汉市为研究区域,以大规模出租车数据为数据基础,结合拥堵识别指标,简要分析武汉市常发性拥堵时空特征。以路段的拥堵属性和路段之间的空间邻近关系为参数,采用谱聚类等方法将武汉市分为42个交通小区。然后,结合第一次地理国情普查数据,计算各交通小区内的景观指数和交通运行指数。最后以交通运行指数为因变量,各景观指数为自变量进行多元回归分析。结果表明,紧凑的城市发展模式和合理的土地利用模式可能会降低拥堵发生的概率,改善道路交通运行状况。
To explore the relationship between land use compactness and urban traffic congestion,we take Wuhan as the research area,use large-scale taxi data and congestion identification indicators to briefly analyze the spatio-temporal characteristics of frequent congestion in Wuhan.And then Wuhan is divi ded into 42 traffic zones through spectral clustering and other methods while taking the congestion properties of road sections and spatial proximity relationship between them as parameters.Next,landscape indexes and traffic performance indexes are calculated with data from the first national geographic census.Finally,multivariate regression analysis is performed with the traffic performance indexes as the dependent variables and each landscape index as the independent variable.The results show that compact urban development may reduce the probability of congestion and improve urban traffic condition.
