英文摘要: Specific topological structures are defined as some simple network structures with nice topological properties and mathematical properties. They are the minimal topology for flow operations in the traffic assignment algorithms, and can be regarded as elemental blocks to study the traffic assignment algorithms. Experiences from current literatures indicate that employment of specific topological structures and their utilization methods have key effects on the convergence performance of traffic assignment algorithms. Here we emphasize the significance of these specific topological structures in analyzing and designing traffic assignment algorithms, and plan to study traffic assignment algorithms by these specific topological structures. Our research content includes: ①Collect and explore specific topological structures with potential properties for designing traffic assignment algorithms, and build the equality conditions between the traffic assignment problem and the specific topological structures; ②analyze the role of specific topological structures in designing traffic assignment algorithms and summarize well properties of advanced algorithms that can be used for others; ③analyze and compare the impact mechanism of different specific topological structure or their utilization methods on convergence performance of traffic assignment algorithms; ④improve current algorithms or design new algorithms by proper use of specific topological structures. Our research is expected to improve the current state-of-art of traffic assignment algorithms, and provide quick and efficient solutions to the planning, design and management of the urban transportation network.
