摘　　要：居民出行OD数据是交通规划中最重要的基础资料之一。传统的利用纸和笔、电话调查以及路边询问等调查方式虽然简单,但存在较大局限性。随着信息技术、移动技术等的发展,手机信息和定位技术应用于交通数据采集是研究的热点之一。在CDMA通信网络和gpsOne手机定位技术的基础上,对出行者进行连续位置跟踪,通过数据处理提取出行者的起讫点位置信息,再结合已有交通区划分,根据点与多边形关系的算法中的面积判断算法得到出行者的OD信息。最后利用所提出的方法对重庆市九龙坡区杨家坪地区进行了OD调查,得到OD发生集中专题和OD线专题。Origin destination （OD） traffic data is one of the most important basic data in the tragic planning. Although the traditional traffic inquiries with pen, paper, telephone etc. are simple, they also have many limitations. With the develop- ment of information and mobile communication technologies, it is a hot issue to collect tra^c data by mobile phone location technology. The consecutive location of travelers is traced by CDMA communication network and gpsOne technology. Then the information of beginning and end points location is extracted by data processing. Combining with the given traffic region division, the OD data of travelers can be obtained by area-judgment calculation, which is a part of the algorithm between point and polygon. Finally, the proposed method is used to make an OD survey at the area of Yangjiaping in Jiulongpo Dis- trict in Chongqing, and topics of OD centralized occurrence and OD-line are obtained.
