Evaluation and decision of bus route for bus route reorganisation

世界上许多大城市的公交网络未必有效。低效率的情况之一是“群集效应”，即几个总线聚集在一起，这会导致实际频率降低。因此，为了在大城市实现高效的公交网络，本研究提出了两种模式；第一个模型是考虑车辆到达站点之间相关性的公交分配模型，第二个模型是考虑乘客行为更准确地同时确定公交网络配置和频率的模型。并将后一种模型应用于广岛市公交网络。

Many of the bus networks in the big cities all over the world is not necessity efficient. One of the inefficient situation is the "bunching effect" where several buses is aggregated, which causes reduction of actual frequency. Therefore, in order to realise a efficient bus network in the big cities, this study proposed two types of model; the first one is a transit assignment model considering the correlation between vehicles' arrival at stops, and the second one is a model for simultaneously deciding the transit network configuration and frequency considering the passengers' behaviour more accurately. Furthermore, the latter model was applied to Hiroshima bus network.
