道路网约束下的事件时空交互检验方法研究

Test Methods for Space-time Interaction of Events Under Road Network Constraints

  • 摘要: 针对沿道路网分布的事件时空交互检验,构建网络约束下的事件空间权重矩阵,并利用事件本身的属性信息进行加权。在此基础上给出矩阵的计算方法,由此将Baker’s修正Knox时空交互检验方法扩展到网络空间。实验结果表明,本文方法可以灵活的衡量沿道路网分布事件的时空交互强度,从而为城市管理者提供一种道路网约束下的定量化时空交互检验手段。

     

    Abstract: Many events happen in cities are distributed along the road network. Thus traditional space-time interaction tests often produce biased results. In this paper a network-constrained spatial weight matrix is formalized,and weighted according to the inherent properties of city events. This matrix is applied to the Baker's modified Knox test. The results show that with this new matrix, test methods are more flexible and net work-based when measuring space-time interaction intensity. For city management decision makers,this is a new approach for space-time interaction tests under road network constraints.
