Abstract In a local area in Japan, several villages exists with small population. In such area, the buses operated in a timetable sometimes become empty, because of the small demand of the transportation. However, the bus is needed for the residents without cars and must be kept as a public transportation. To operate the buses more efficiently, on-demand bus systems are operated in several areas. Full on-demand bus is an on-demand bus system without a timetable, which moves to the place where the passengers call the bus. The bus is different from the taxi, because it may pick up other passengers at other places. This paper deals with the system with two full on-demand buses which are operated between the center of the area and villages. The demand distribution is assumed by Poisson distribution. The system is formulated by a Markov process and the expected demands satisfied by the system is calculated. The expected demands satisfied by one bus is also calculated and it is compared with the value of the system with two buses.
