Simulation of Traffic Flow in Hurricane Emergency Evacuation Use Dynamic Control Strategy

Article Preview

Abstract:

Based on the hurricane evacuation process, the dynamic characteristics of hurricane disaster risk were analyzed. The degree of harm and endanger regional are the two aspects of dynamic characteristics of hurricane disaster risk and by use the hurricane center and hurricane levels, the risk measurement method for a given point was proposed. The new emergency evacuation strategy was based on the largest decline of unit risk which was also the main idea of vehicle steering decision function. By the hurricane evacuation examples, the case that traffic net with traffic bottlenecks was studied by simulation. The results show that the proposed hurricane emergency evacuation strategy of this paper is feasible and have practical implications.
