【摘要】 系统研究了以PDA(个人数字助理)为平台的公共交通系统的设计思路,详细阐述了各模块的功能和关键技术的实现方法。最后利用组件技术在Dotnet环境下实现了基于PDA的公共交通系统的原型系统。以北京市公交数据为实验,实验结果表明该系统能够很好地满足城市公交信息的查询,为以后的公共交通系统的设计和实现提供了理论和实践基础。更多还原

【Abstract】 This paper systemically studies the design of PDA(Personal Digital Assistant)-based public transportation system,and specifies functions and key techniques of every module.Then the prototype system is realized in Dotnet environment using component technique.Public transportation data in Beijing is chosen to be the study data.Experiment result shows that system can satisfy the query of city public transportation information,and be the based on which further public transportation design and realization can be studied.更多还原
