基于Storm的高速公路实时交通指数评估方法的研究与实现

随着高速公路飞速的发展，出现的拥堵增加、监控困难等问题也日益严峻。首先本文在北京市城市交通拥堵指数的基础上，提出了利用交通指数对高速公路运行状况进行评估的方法，然后基于Storm大数据平台，实现了交通指数评估系统中的数据处理、分析、指数后台计算关键算法，最后通过手机APP、微信公众号等形式，实时地发布高速公路交通指数。实验结果表明：高速公路交通指数不仅可以反映整体的高速运行状况，也可以反映特定高速或者特定高速区间的实时拥堵情况，还可以实时监测高速路网的拥堵情况，为居民出行提供参考，对缓解道路拥堵起到积极作用。

Research and Implementation of the Real-time Highway Traffic Performance Index Evaluation Method Based on Storm

With the rapid development of highway, the emergence of increased congestion, monitoring difficulty and other issues are increasingly seriously. Firstly based on the urban traffic performance congestion index of Beijing, this paper proposes a method to evaluate the status of highways through utilizing traffic performance index. Then based on the big data platform of Storm, this paper implements data process, data analysis and key algorithms of index background calculation. Finally the real-time traffic performance index is published in the form of mobile phone APPs and official accounts of Wechat.The experimental results show that highway traffic performance index can not only reflect the overall status of highways, but also can reflect the real-time congestion situation of specific highways or specific highways range, but also can real-time monitor the congestion situation of highway road network, which provides a reference for people and play a positive role to ease road congestion.
