MARKOV MESOSCOPIC SIMULATION MODEL OF OVERFLOW QUEUES AT MULTILANE SIGNALIZED INTERSECTIONS

This paper analyzes the interdependency between the dynamics of queues at isolated signalized intersections and the lane-changing behavior of vehicles approaching the intersection. A dynamic queuing model based on Markov Chain renewal process is combined with a lane-changing behavior model in order to simulate the vehicle distribution in time. We applied this simulation to a two-lane intersection, showing how queues influence lane changing before the intersection. Finally we study the case including an accumulation lane, showing how the spillback effect can also influence travelers’ lane changing.
