A motion control system for an independent cart system provides for an improved system for controlling operation of movers in areas of high traffic. A controller monitors operation of the movers to detect heavy traffic. In heavy traffic, the controller may bring a mover to a stop to avoid collisions. Once a mover is stopped, the segment controller will look at the present location of the mover and determine whether it is at the desired position set in the motion command. If the mover is not at the desired position, the stop was a result of heavy traffic. After detecting heavy traffic, the controller commands the mover to resume travel using a modified motion command. The modified motion command will command the first mover to its desired position but will command the move at a reduced rate or using a reduced response in the controller.
