TOWARDS A FRAMEWORK FOR ROAD NETWORK VULNERABILITY ASSESSMENT

The vulnerability of road networks in emergency situations is a subject of increasing importance. In general, the identification of vulnerable spots in the network is important to identify the needs for network maintenance and for the allocation of emergency services. Although it is of crucial influence on the success of acute evacuation, the vulnerability of the road network for acute mass-evacuation, is often ignored. It can help to increase the insight in the consequences of link failure on the evacuation process. Furthermore, the use of the available evacuation time can be optimized by using the road network as long as possible. This paper introduces a framework for evacuation modeling on disrupting networks using the MaDAM dynamic traffic assignment algorithm including route choice and aims to derive the importance of links in the network.
