Evacuation Transport Provision Design Using Network Analysis with Gis Support

The research presented in paper has focused on design of the transportation evacuation during a special flood caused by an accident at a water structure using GIS-enabled network analysis. Freely available population and address point data were used to calculate the number of residents at risk. Three scenarios of time required for each evacuation activity were determined using the PERT method, and the time required for evacuation was determined using a Gantt chart. The approach proposed in the paper is suitable for obtaining relatively quick results that can be taken into account when preparing for crisis events. The results of the case study proved that the evacuation can be carried out in the necessary time, but revealed possible shortcomings of the proposed approach. These shortcomings are discussed along with possible alternative solutions and other factors influencing the evacuation planning process.
