Emergency Management System for Major Traffic Accidents Based on New Model and Algorithms
Scientific and effective emergency evacuation traffic management plays an important part in improving event reaction ability of urban traffic system, saving rescue time and reducing property losses. A new approach for real-time traffic management under emergency evacuation is proposed in this paper. Distinct from the well-studied evacuation planning, realtime traffic management for evacuation aims at dynamically controlling traffic flow under evacuation in such a way that certain system objective like minimization of evacuation time could be achieved We take into account the idea of feedback in the executing process based on the real-time information obtained from sensors and other surveillance technologies. Updating the evacuation plans is essential and brings the following two advantages: firstly, it prevents congestion, by creating new evacuation routes and thus avoiding the already crowded areas; and secondly, it decreases congestion by directing traffic on currently congested routes to disperse on alternative routes. A numerical example is given to illustrate that the proposed approach can be effectively carried out in emergency evacuation.
