The invention discloses a smart city road management method and system based on big data. The method comprises the following steps: step 1, obtaining a congestion characteristic curve of a smart city road; step 2, according to the smart city road environment characteristics of the congestion characteristic curve of the smart city road, obtaining the probability of occurrence of an accident on each smart city road; and step 3, according to the congestion characteristic curve of the smart city road and the probability of occurrence of the accident on each smart city road, obtaining the category of the accident on the smart city road. According to the invention, the situation that the road weather environment cannot be ensured when the congestion characteristic curve of the smart city road is obtained and the sampling frequency is low, so that the characteristic curve error is large can be avoided, and the accuracy of traffic jam or accident prediction of the smart city road is ensured.
本发明公开了一种基于大数据的智慧城市道路管理方法及系统,包括如下步骤:步骤1,获取智慧城市道路的拥堵特性曲线;步骤2、根据智慧城市道路的拥堵特性曲线的智慧城市道路环境特征,获得每条智慧城市道路上出现事故的概率;步骤3、根据智慧城市道路的拥堵特征曲线以及每条智慧城市道路上出现事故的概率,获得智慧城市道路上出现事故的类别。本发明能够避免因获取智慧城市道路的拥堵特性曲线时无法保证道路天气环境以及采样次数不多而导致的特性曲线误差较大的情况,保证了智慧城市道路发生堵车或者事故预测的准确性。
