摘　　要：随着城市规模的不断扩大,道路拥堵已经成为制约经济发展以及影响居民生活的一个重要因素,根据道路交通速度发现拥堵成为了解决这一问题的首要手段。道路交通速度计算的准确性和时效性是影响动态交通管理措施实施效果的关键因素。本文利用GPS浮动车技术获得的流数据,引入实时计算和流式计算平台Storm对数据进行分析处理,通过道路速度计算达到实时发现拥堵交通的目的,为交通管理部门疏导交通以及广大用户出行的道路选择提供参考依据。With the expansion of city scale,road congestion has become an important factor which restricting economic development and influencing residents'life.Discover congestion according to road traffic speed is the primary method to solving this problem.The accuracy and timeliness of road traffic speed calculation are the key factors of the implementation effect of dynamic traffic management measures.This thesis provides reference for traffic management department to analyze traffic jam and to channel traffic and road choice for users by using stream data acquired from GPS floating car and technology and introducing the real-time calculation and stream computing platform Strom to calculate the road real-time speed.
