基于感应线圈数据的城市道路交通状态判别方法

Identification method of urban road traffic conditions based on inductive coil data

以SCOOT系统感应线圈检测器采集到的交通数据为基础,设计了一种基于模糊聚类的城市道路交通状态实时判别算法及其评价方法,并提出了交通状态判别时间间隔的确定方法。以VISSIM为工具,对上述方法进行了模拟。对比分析结果表明,所提出的算法能够提高城市道路交通状态实时判别的效果。

A real-time method identifying the urban road traffic conditions and its evaluation approach were proposed based on the fuzzy clustering algorithm and the data from the inductive coil of the SCOOT traffic signal control system.A method to determine the idenlification time interval was also presented.A simulation was performed by software VISSIM to confirm the proposed methodology.A comparative analysis show positive and encouraging results.
