摘要
从移动通信系统获取手机信令数据,根据重庆手机信令数据特点,提出了数据预处理、基站小区定位、出行链识别、分区统计及结果扩样方法,获取居住人口分布、通勤岗位分布、跨区人流OD(origin-destination)。此方法具有覆盖范围广、分析样本大、实施成本低、可长期连续监测的优势,可为城市规划提供了一种全新的数据获取手段。在重庆市城乡总体规划(2007—2020年)深化工作中,基于重庆联通手机信令数据,分析重庆主城与区县及各区县之间的人流交换,定量地评价城市间联系度及城市区位优势,以此为基础开展客流需求预测,作为优化城镇体系结构、调整区域发展战略,规划布局铁路与公路网的依据。
With the cell phone data from mobile communication system, after a series of technical methods processing such as base station positioning, data filtration, travel behavior recognition and sample expansion, the distributions of resident population and employment, OD matrix between large zones can be acquired. This method has obvious advantages of low cost, wide coverage, large sample, continuous observation, and can be used as a new means for data collection in urban planning. In Chongqing Urban-Rural Master Planning （2007--2020） , the population exchange within Chongqing was ana- lyzed based on the CQ Unicorn mobile signaling data, and quantitatively evaluated the connection degree between counties. The result was used for aligning each county＇s development strategy and as a basis for passenger demand forecasting for rail or expressway network layout planning.
