摘要
基于对快速路交通状况的分析,提出建立先进交通监控系统的必要性.构建了由外场设备、通信系统及监控中心构成的系统总体架构.建立了交通检测数据优化模型、交通状态自动辨识模型和实时行程时间预测模型,并应用于快速路交通监控系统建设和运行.
According to an analysis of current traffic condition of Shanghai urban expressway, this paper advocates it is very necessary to build a reliable and efficient advanced traffic management system （ATMS）. This paper introduces the general framework of ATMS which is composed of field equipments, communication system and control center. The paper also presents three key traffic models including traffic data optimization model, traffic state identification model and travel time forecast model which have been applied to the ATMS for Shanghai urban expressway.
