报告摘要：The traffic assignment problem (TAP) aims to determine a traffic flow pattern by allocating the origin-destination (O-D) demand trip table to the transportation network based on some route choice principle. It is an essential and fundamental step in transportation planning and management. Hence, developing effective solution algorithms for solving TAP in large-scale transportation networks is of interest to both practice and academic research. In this seminar, I will first review the basic TAP and its associated traffic assignment algorithms used in practice and state-of-the-art research. Then I will focus on the path-based gradient projection (GP) algorithm due to its efficiency and flexibility in solving a wide range of applications in transportation. To conclude, I will provide some recent developments and new ideas for future research.
