摘要
为解决道路交通状态数据的缺失或异常等问题,本文提出了一种道路交通信息模板的有效设计方法。该方法首先对道路交通状态信息的规律性进行了分析,然后基于不同的划分标识对道路交通运行模态进行了有效划分,最后对不同模态下的道路交通状态的规律性信息进行了有效提取,最终实现了道路交通信息模板的有效设计。选取了北京市典型快速路对该方法进行验证,结果证明基于道路交通信息模板修复的道路交通状态数据具有高精度,在实际应用中是可行的。
To solve the problems of road traffic state data invalid or data deletion, an effective design method of road traffic information template is presented to repair the road traffic states data. First, the regularity of road traffic state information is analyzed. Then, the road traffic running modes are effectively divided into several different modes based on different partition identifications. Finally, the regularity information of road traffic states under different modes is effectively abstracted, and the effective design of the road traffic information template is realized. Some typical freeways in Beijing are adopted for verification. The results prove that the traffic states data recovery based on road traffic state information template is feasible and can achieve a high accuracy.
