针对城市交通基础设施数据采集中的瓶颈问题,对个人数字助理(persona l d ig ita lass istan t,PDA)在交通基础设施数据采集中的应用进行研究,从数据结构和软件结构两方面进行分析,介绍基于PDA的数据采集系统软件的开发和应用,该系统已在我国各大城市的城市交通基础设施的数据采集中得到应用。

Aiming at the bottleneck problem of data collection in City Transportation Infrastructure Management System （CTIMS）, this paper dealt with the application of Personal Digital Assistant （PDA）to data collection. Then, the data structure and program structure were analyzed. Moreover, the data collection system based on PDA was developed. The system has been successfully applied to city transportation infrastructure data collections.
