  • 定义时空对象代替空间对象作为基本研究单元, 改进传统Moran's I指数为时空Moran's I指数, 以便适于分析道路交通的时空特性; 通过Moran散点图给出时空自相关意义下的交通流时空状态特征分类: 拥堵聚集、畅通聚集、拥堵异质和畅通异质.为说明改进时空Moran's I指数分析法的实际应用价值, 以北京市二环快速路外环方向的车流速度数据为例, 进行时空自相关指标计算, 并从全局与局部自相关两个方面分析时 空自相关指标所反映的交通状态时空分布与演化规律.
    An improved Moran's I method is proposed to describe the spatio temporal features of road traffic flow based on the traditional Moran's I. The spatio temporal distribution classification of road traffic status including homogenous congested and uncongested traffic, heterogeneous congested and uncongested traffic is then given through Moran plotting graph. To verify the applicability of the proposed method, the traffic flow data along the second ring-shape urban expressway in Beijing is introduced for analysing the spatio temporal distribution and evolution of road traffic status from global and local autocorrelation through using the proposed method.
