Abstract In a transportation system, a merging control strategy is necessary to avoid collisions between vehicles at a merging section with entry lines. In this study, under the assumption that each entry line is assigned time‐independent priority, we analyze traffic congestion with a stochastic model. A quantitative estimation of the congestion is successfully obtained in terms of the average queue length and the average queuing delay. On the basis of analytical results, we propose a control strategy that changes the priority periodically. Using simulation, it is clarified that the proposed control strategy gives arbitrary values of the queue length and the queuing delay on each line. © 2012 Wiley Periodicals, Inc.
