Estimation of Optimal Trip Matrix Considering Emergency Vehicles in Earthquake Disaster

Abstract

This paper presents the estimation method of optimal OD trips matrix for the traffic control policies in relief management of earthquake disaster. The problem to be addressed is a multi-commodity, 2-modal network flow considering the emergency vehicles (supplies and relief personnel) and private cars. The formulation of problem is based on the concept of network flow theory and Linear Programming. The OD traffic pattern of private cars is analyzed by the upper and lower bound of OD traffic volumes and two kind of unit OD traffic volumes.
