Summary: 
Traffic control/operation system based on information gathered from probe vehicles has attracted a great deal of attention. In this paper, we propose and evaluate a novel traffic management to provide information with anticipatory stigmergy which shares the locations of probe vehicles in near-future and searches an alternative route to avoid expected congestion. Because it might be ineffective if all drivers follow the fastest path searched by anticipatory stigmergy, we introduce new strategies for assigning a driver to a path based on the residual distance to his/her destination or the time involved in congestion from his/her departure. In addition, the impacts of driver's route choice behavior to follow the recommended route are examined as sensitivity analysis. The results of our numerical experiment show that our proposed anticipatory stigmergy with assignment strategy works better than the conventional way.
