Intersection Group Dynamic Subdivision and Coordination at Intraregional Boundaries in Sudden Disaster

Algorithm 1

Step  1. Takes the signalized intersection as the central intersection in intersection group, delivers outward

the coordination traffic signal cycle sequentially.

Step  2. Obtains the common signal cycle of intersection group, let .

Step  3. Reassignment the expected traffic signal cycle to the intersection in intersection group of

intra-regional boundaries.
