The embodiment of the invention provides a data analysis method and device for an urban road network, and the method comprises the steps: determining a space-time influence range of an emergency according to the obtained speed data; according to the space-time influence range, determining a space-time propagation rule of the emergencies in the urban road network; and expressing the space-time propagation rule in a linear constraint manner, and estimating the space-time influence of the emergencies of the urban road network through the optimization model. Compared with the existing method, the estimation method provided by the invention considers the space-time propagation rule of the influence of the emergency on different road topological structures, and the estimation result of the model meets the propagation rule of traffic waves, so that the reasonability of the estimated space-time influence range is ensured.

    本发明实施例提供的一种城市路网的数据分析方法和装置,包括:依据获取的速度数据,确定突发事件的时空影响范围;依据时空影响范围确定突发事件在城市路网的时空传播规律;将时空传播规律以线性约束表达,通过优化模型对城市路网的突发事件的时空影响进行估算。相比于已有的方法,本发明所提出的估算方法考虑了突发事件影响在不同道路拓扑结构的时空传播规律,并且模型的估算结果满足交通波的传播规律,确保了所估算时空影响范围的合理性。
