摘要:手机作为一种理想的交通探测器,为居民出行信息分析提供了很好的技术选择。将手机数据映射至交通分析单元,并经信息预处理、匹配分析、交通模型分析处理、数据去噪、扩样等一系列海量数据运算处理,最终可获得居民出行特征数据。利用长期历史手机话单数据,可分析常住人口和就业人口分布、通勤出行特征、大区间OD、特定区域出行特征、流动人口出行特征等。手机信令数据能够较完整地识别手机用户的出行轨迹,可进一步应用于分析城市人口时空动态分布、特定区域客流集散、查核线断面或关键通道客流、轨道交通客流特征、出行时耗、出行距离、出行强度、道路交通状态等。根据天津手机话单数据应用案例及上海手机信令数据应用案例,验证了技术可行性。

Abstract:Because of its advanced technology features, mobile phone is an ideal tool for travel data collection. By populating cell phone locations on traffic analysis zones, this paper introduces how to obtain residents’ trip characteristics and their travel patterns by processing massive cell phone usage data for travel demand forecasting purposes. Specifically, this paper presents how to use long-term historical cell phone information (cell phone bills showing the time and locations of all calls) to estimate distributions of resident population and employment, commuting travel characteristics, OD matrix between large zones, travel characteristics of specific areas, and floating population travel characteristics. Since cellular signaling data can be used to accurately identify mobile phone user’s travel path, it can be further used to estimate the dynamics distribution of urban population, distribution of passenger flow in given areas, passenger flow at concerned locations or within key corridors, characteristics of rail transit passenger flow, travel time, travel distance, travel demand, road traffic performance, and etc. Case studies conducted in Tianjin and Shanghai are presented to demonstrate this technology application.
