摘　　要：既有研究中关于跨域的出行特征分析主要基于单一来源数据,如手机数据或互联网位置数据,缺乏多方式的运营数据。基于长三角范围高速公路网、铁路网等骨干基础设施网络,对各区县手机信令OD、高速公路收费站OD数据、铁路站点OD数据、互联网OD数据等多源数据进行融合分析并校核,建立长三角范围基于铁路和高速公路的分方式出行及运营模型,分析了上海与长三角其他城市间的出行量、公铁分担、客货情况等出行特征。在此基础上,基于高速公路收费站OD数据及断面流量监测数据,构建上海大都市圈范围的高速公路网分配模型,评估了上海对外高速公路通道的运营服务水平、跨界流量的溯源分布情况以及上海各个片区的高速公路流量进出情况。两个模型可为长三角城市间跨界统筹交通资源、为上海大都市圈内高速公路通道精准优化治理提供决策支撑。In existing research,analyses of travel characteristics across regions primarily rely on data from single sources,such as mobile phone data or internet location data,lacking multimodal operational data.This study integrates and verifies multiple data sources,including mobile signaling Origin-Destination(OD)data,highway toll gate OD data,railway station OD data,and internet OD data,based on the Highway and railway networks.of the Yangtze River Delta region.It establishes a mode-specific travel and operation model for the Yangtze River Delta region using railways and highways,analyzing travel volumes,the division of responsibilities between public and railway transport,and passenger and freight conditions between Shanghai and other cities in the region.On this basis,using highway toll gate OD data and section traffic monitoring data,a highway network allocation model is constructed for the Shanghai metropolitan area to evaluate the service level of outbound highway channels from Shanghai,trace the distribution of cross-boundary traffic flows,and analyze the entry and exit highway traffic in different areas of Shanghai.The two models provide decision support for the coordinated management of transportation resources across cities in the Yangtze River Delta region and for precise optimization and governance of highway channels within the Shanghai metropolitan area.
