Many algorithms have been presented to solve the traffic assignment problem. Recently, Bar-Gera introduced the concept of “last common node” into an origin-based algorithm to solve the traffic assignment problem. However, how to find the last common nodes has not been investigated in detail. In this paper, we present a matrix method for finding the last common nodes in an origin-based traffic assignment...
Frank-Wolfe (FW) algorithm is widely used to solve traffic equilibrium assignment problems. It has the characteristics of simple implementation and modest memory requirement. However, it also faces some problems such as slow convergence, no providing path information, and so on. In order to improve its implementation efficiency, the FW algorithm is furthermore studied from three flow update strategies...
