In this paper an autonomous vehicle scheduling scheme is proposed in large physical distribution terminals publicly used as the next generation physical distribution bases. This scheme uses Learning Automaton for vehicle scheduling based on Contract Net Protocol, in order to obtain useful emergent behaviors of agents in the system based on the local decision-making of each agent. The state of the automaton is updated at each instant on the basis of new information that includes the arrival estimation time of vehicles. Each agent estimates the arrival time of vehicles by using Bayesian Learning Process. Using traffic simulation, the scheme was evaluated in various simulated environments. The result shows the advantage of the scheme when each agent provides the same criteria from the top down, and voluntarily generates criteria via interactions with the environment, playing an individual role in the system.
