緊急支援物資輸送(ERL)シミュレーションに関する基礎的検討

Abstract

In this study, simulation model of cargo trucks in disaster area was proposed for Emergency Relief Logistics (ERL). The model was a micro traffic simulation model, consisted of cargo truck agents and small vehicle agents. The model included an effect of an interruption of traffic signal, because of electric power failure due to an earthquake. Trial simulations were conducted for the central area and suburbs of Kochi City, Kochi Prefecture, and result of the simulation showed that an average speed of cargo truck was constant, 28.4 -28.5 km/h in conditions of low density traffic. In contrast, the simulation also showed 'Grid lock' traffic jam around some intersections, and cargo trucks could not access to a stock-yard in traffic conditions of a specific density and higher density.
