Abstract There are few users of a bus at a depopulated area. The abolition of the bus line is a serious problem for children and the senior citizens in the area. Therefore, the bus service of the on-demand bus system has been proposed, which is operated in response to users’ request. This paper deals with the Demand Responsive Transport (DRT) which is operated between points requested by users. The demand is generated stochastically and one car serves users in the order of their requests. The car can process multiple requests simultaneously, which is different from the ordinary taxi in Japan. The car will move to the specified waiting point if there is no requests and no passengers. For this system, we propose a model based on the discrete time Markov chain to calculate the expected waiting time. The waiting time is defined as the time from the request epoch to the arrival epoch to the destination. The value is used to evaluate the system, and useful to determine the waiting point to minimize the value, when there are several candidates of the point.
