Applications of Dynamic Partitioning of Intersection Group

An urban intersection group consists of a set of intersections which are geographically adjacent and strongly correlated with each other [1]. It is the minimal network for traffic control and coordination control. In this paper, based on the dynamic partitioning results of the intersection group provided by the software and data collected by traffic flow detectors, the features of dynamic partitioning software for intersection group are further explored from two aspects: traffic control and emergency response to traffic accidents, using the method of green-wave control and traffic guidance respectively.
