The objects of the research are to develop models and/or techniques for developing efficient diversion strategies in the event of blockage of portion of and urban network due to congestion-causing events, and to develop computer programs for real-time implementation of diversion strategies. To achieve this, a two-pronged research approach is being adopted. In the first approach, namely, the user-optimal approach, the basis of diversion is to re-route the motorists through the best alternate paths to their destinations. In the second approach, namely, the system-optimal approach, attempt is made to effect diversions to optimize the utility of system facility. The report centers on the user-optimal approach, where information on traveller destinations is a key to effective and efficient diversions. After reviewing state-of-the-art systems for traffic management, a mathematical model is developed to estimate traveller destinations, utilizing link traffic volumes. It is based on linear programming approach, employing the efficient column generation technique. Model testing, evaluation, and comparison with other models of similar function are presented.
