2008年四川大震災後の交通ネットワークの信頼性改善法の研究

抄録

This paper presents a method for network reliability improvement of the road network of Mianyang City after the 2008 Sichuan earthquake in China. In order to improve the network reliability of Mianyang traffic system, the damage of the traffic system in this earthquake and the problem on the traffic system is stated firstly. Secondly, the present condition of disaster prevention planning in China is introduced. Since it is very difficult to obtain the exact values for the set ofthe link reliability of Mianyang road network after this earthquake, an assumption for calculating link reliability is proposed. Based on this set of link reliability, road network reliability is improved using the Importance Analysis. At the sametime, cost-benefit analysis is calculated with two cost-reliability functions.
