摘要: 介绍了单线圈在交通参数测量中发挥的作用,阐述了单线圈模式下进行交通流参数估算,主要是交通速度估计的意义和目前采用的主要算法.在此基础上,利用交通流仿真软件PARAMICS并应用此软件搭建单线圈路网模型,通过它获得单线圈模式下交通速度估计的仿真数据,并对数据进行了分析.

关键词: 交通流, 参数估计, 交通速度, 交通仿真

Abstract: in the paper a detail traffic parameter estimation method on single loop detection is shown, speed is mainly focus, there are two methods that are used in the paper, using traffic simulation software-PARAMICS simulation data can show the result of estimation methods. The advanced traffic information system can be set up supported by these data.
