摘　　要：电子商务的兴起促使城市货车交通量的激增,对交通规划与管理产生显著影响。然而,解析城市货车交通量空间分布及其影响机理的实证研究仍相当有限。因此,综合考虑经济属性、土地利用、道路基础设施等建成环境变量,通过应用空间计量模型识别城市货车交通量空间分布的主要影响因素。研究结果表明,相较于客运车辆,城市货车交通量具有更为明显的空间集聚效应,其空间分布受到大型对外交通基础设施选址、高等级道路布局的显著影响。研究结果有助于识别潜在的客货车辆混行区域的空间分布并制定管控措施。A significant increase in urban truck traffic following the advent of e-commerce has resulted in a profound impact on traffic planning and management.However,the spatial distribution and driving mechanisms behind urban truck traffic have not been extensively studied.Therefore,a comprehensive approach is adopted in this research,examining built environment such as economic attributes,land use,and road infrastructure.Spatial econometric models are employed to identify the key factors influencing the spatial distribution of urban truck traffic.It is discovered that urban truck traffic exhibits a more pronounced spatial agglomeration effect compared to passenger vehicles.This distribution is greatly influenced by the location of major external transportation infrastructure and the structure of superior road networks.These findings contribute to the identification of spatial configurations of potential areas where passenger and freight traffic overlap,thus aiding in the formulation of regulatory policies.
