【摘要】 智能交通系统已经成为21世纪交通运输体系的发展趋势,其实质是对交通信息的分析、共享和综合利用。通过对智能交通系统采集的初始交通信息进行预处理可以为智能交通系统中数据分析的正确性和可靠性提供保证。本文在分析采集自上海市交通路口的交通数据的基础上,对交通数据的预处理和数据恢复、路段拥塞程度分析进行了探讨,并在此基础上提出了一套进行交通数据处理和分析的计算机平台实现方案。更多还原

【Abstract】 The main trend for transportation architecture in 21 century is Intelligent Transportation Systems(ITS).The analysis and sharing and integrated usage of traffic information is Essential of ITS.The pretreatments of initial traffic information collected by ITS can make certain the correctness and dependability of traffic data analysis.Based on the analysis of traffic information collected from crossings in the city of Shanghai in China,this paper discusses pretreatments of traffic information flow and how to analyzes the degree of crowd in crossings.On this basement,this paper not only proposes a design scheme of computer platform for processing and analyzing traffic information,but also analyzes its function structure and the function requirement.更多还原
