摘要
旅行时间作为道路交通状态的重要参数,对交通信号运行方案的制定与优化有着极为重要的意义。针对道路检测器法、摄影量测法、牌照法等旅行时间检测方法存在人力物力消耗大等问题,通过对GPS轨迹数据的特点与旅行时间的估测原理进行分析,提出利用GPS轨迹数据进行城市道路旅行时间的检测方法,并利用极大似然等方法对测量的旅行时间进行处理,最后选取北京石景山区路段搭建VISSIM仿真平台,进行模型验证。
As an important parameter of road traffic condition,travel time is of great importance to the formulation and optimization of traffic signal operation scheme.For road detector method,photographic measurement method,license plat method and other traditional travel time detection method of some problems such as resources is used up big,by analyzing the characteristics of GPS trajectory data and the estimation principle of travel time.This paper proposes an estimation method of urban road travel time using GPS trajectory data,uses maximum likelihood method to deal with the travel time measured,and selects the section of Beijing shijingshan district to build the VISSIM simulation platform for model verification.
