上海市主城区公共交通分担率与土地利用相关性

上海市主城区近30年公共交通与土地利用发展历程充分体现了公共交通分担率与人均城市建设用地面积的紧密关系。利用上海市综合交通调查数据和交通模型，定量分析主城区土地利用效率与公共交通分担率的相关程度，指出人均城市建设用地面积越大、公共交通分担率越低，且公共交通分担率存在阈值。同时探讨城市功能空间布局对公共交通分担率的影响，上海市主城区不同区域、不同出行方向的公共交通分担率有明显差异。最后指出，公共交通分担率的目标设定需要结合城市用地开发同步考虑和深入研究，不能一概而论。

Relationship between Transit Travel Mode Share and Land Use in Main Urban Area of Shanghai

The development history of public transportation and land use of main urban area in Shanghai over the past 30 years has sufficiently illustrated the close relations between transit travel mode share and average urban land use development per capital. Based on the data obtained from Shanghai comprehensive transportation survey and transportation planning model, this paper analyzes the relationship between land utilization efficiency and transit travel mode share in main Shanghai urban area, which indicates that the larger the per capita land use area, the lower transit travel mode share under the maximum share of transit service. The impact of the spatial layout of urban functionalities on transit travel mode share is also dis-cussed, which shows great difference in locations and travel directions in main urban area of Shanghai. Fi-nally, the paper points out that the targeted share for transit should be simultaneously considered with ur-ban land development and thorough research.“One-size fits all”solution does not exist.
