1 1 1 1 1 NetMAS NetMAS NetMAS One-dimensional Model for Fast Evacuation Simulator Shunsuke Soeda, 1 Tomohisa Yamashita, 1 Masaki Onishi, 1 Ikushi Yoda 1 and Itsuki Noda 1 We propose the one-dimentional pedestrian model, which simplifies the representation of space for fast calculation. The model was implemented into NetMAS, an evacuation simulator. The validity of the model was confirmed by comaring simulation results with data observed from an evacuation drill. The effectiveness of the model was confirmed by running many simulations. 1. 1 National Institute of Advanced Industrial Science and Technology (AIST) Strategic level Tactical level Operational level 1),2) Strategic level Tactical level Operational level Operational level NetMAS NetMAS 2. 3) 4) 6) 7) 9) 1 1 c 21 Information Processing Society of Japan
