| Abstract: | This dissertation documents the development of a nodal capacity-restricted dynamic network model for evaluating corrdor traffic management strategies. The basic requirement of corridor control models is that the models should consider both the diversion and restriction aspects of the corridor traffic management philosophy. Currently, simulation models have been used for evaluating the restriction effects of corridor traffic control strategies, but dynamic traffic assignment techniques for evaluating the diversion effects of those strategies are not well developed. The purpose of this study is to develop a new dynamic assignment model that is compatible with simulation models for corridor traffic management purposes. A special feature of this model is its ability to manage different flow characteristics for freeways and arterials, queue and queue spillback, and uncompleted trips for freeway/signalized arterial corridors. The process of dynamic nodal capacity-restricted network model was illustrated with a directed example network. The model was also applied to a portion of the Southwest Freeway corridor in Houston. Comparisons of both the logic of the modeling concepts and the consistency of assignment and simulation results suggest that the nodal capacity-restricted dynamic network model is superior to the existing models for corridor traffic management applications. |
