短时交通流动态预测系统设计

Design of Short-Term Traffic Flow Dynamic Prediction System

随着交通智能化、城市智慧化的发展,短时交通流动态预测系统在ITS建设中愈显的不可或缺。论文旨在对如何完成一套实用性强、性能高的城市道路短时交通流动态预测系统设计的研究。文章围绕系统的逻辑及物理构架,详细分析了各层次、模块单元的业务逻辑及主要功能,又根据实际需要规划出了具体的系统功能模块及内部详细的预测处理流程与预测模型构建思想,预测结果模拟、评估与存储的方法,又分析了该系统的应用与行业意义,最后根据整个系统设计思路,实现了针对西安市的短时交通信息动态预测系统的原型开发,验证了设计思路的合理性及科学性。

With the development of intelligent transportation and intelligent city,the more and more important of shortterm traffic flow dynamic prediction systems in ITS have constructed.The aim of this paper is to study the design of a shorttime traffic flow dynamic prediction system for urban road with strong practicability and high performance.Around the system of the logical and physical architecture,the hierarchical,modular unit of business logic and its main functions are analyzed in detail,And according to the actual need to plan the specific system function module and the internal detailed prediction processing process and prediction model construction thought and prediction results simulate,evaluate and storage methods,and analysis the system application and industry significance,finally according to the system design ideas,the realization of the for Xi＇an short-time dynamic traffic information prediction system prototype is developed to verify the rationality of the design ideas and scientific.
