- Abstract:
- Traffic congestion is one of the most important issues facing modern societies that causes many impacts such as environmental pollutions and waste of physical and spiritual energies. One of the traffic congestion mitigation strategies is network management, which encompasses a diverse range of tools. Efficient management of urban transportation network requires the transportation network information. Traffic equilibrium in the transportation network is one of the fundamental information that is required for most of network management tools. In this study, a multi-modal traffic assignment model with complementarity structure is proposed that can determine the multi-modal traffic equilibrium (with private and public modes) in which the travel demand is shared between all modes. By implementing different travel demand models, the proposed model can be used for modal split in addition to traffic assignment, in transportation networks. The proposed model was solved for several small examples using GAMS software, and two iterative algorithms, namely, mode decomposition algorithm and origin-destination decomposition algorithm. Due to the large size of the model for medium and large networks, and according to the complementary structure, an iterative solution using the ideas of decomposition, path generation and linearization was presented for solving the proposed model
