基于多源交通大数据的高速公路易堵节点甄别分析

Discrimination and Analysis of Freeway Easy-to-block Nodes Based on Multi-source Traffic Big Data

高速公路交通拥堵对高速公路交通运行状态产生非常严重的影响。高速公路管理者应该在交通拥堵发生之前对其进行判别。首先分析了高速公路交通拥堵的演化过程,通过高速公路交调数据、手机数据、多源数据三个方面分析了高速公路易堵节点自动判断及动态甄别技术。以宁沪高速公路为例对其国庆期间易堵路段进行了甄别,并分析了拥堵可视化展示的意义。

Expressway traffic congestion has a very serious impact on the state of expressway traffic.Highway managers should judge traffic jams before they occur.First,it analyzes the evolution process of expressway traffic congestion,and analyzes the automatic judgment and dynamic discrimination technology of expressway easy to jam nodes through three aspects:expressway traffic data,mobile phone data and multi-source data.Taking Nanjing-Shanghai Expressway as an example,the road sections that are prone to congestion during the National Day were screened,and the significance of visual display of congestion was analyzed.
