摘要
居民出行信息是进行城市路网规划、交通评估、交通管理与运营等相关工作的基础数据。传统的OD信息是通过调查的方式如路边询问调查、电话咨询或是发放调查问卷等形式获取。调查过程往往因被调查者隐瞒或遗忘等情形而造成所获取的出行数据基本不可信,失去可以利用的价值。CDMA系统手机定位获取交通信息技术因其可用性高、便捷、使用范围广等优势而越来越受到人们的青睐。介绍CDMA系统的手机定位技术,以及该项技术在居民出行信息采集中的应用,并在文章最后列出在实现过程中可能遇到的问题。
Resident＇s trip OD data is the basic information for urban road network planning,traffic assessment,transportation operation and management,and other relative works. Investigators got the traditional OD information through varieties means such as roadside survey,telephone consultation or in the form of a questionnaire. The obtained trip data is incredible as respondents concealed or forgot the issue in the survey process. Mobile phone positioning technology using CDMA system to obtain traffic data become more and more popular for its high availability,convenience,wide using range and other advantages. This paper describes the mobile phone positioning technology using CDMA system,and its applications in resident＇s travel data,finally listed the problems that may be encountered in the implementation process.
