A Method to Improve the Route-Based Algorithm for Traffic Assignment by Eliminating Route Dependence

Along with the development of computation techniques, the storage memory is no longer a critical bottleneck to the solution algorithms for transportation network models. The researches of the traffic assignment problem (TAP) have focused on the large-scale problems with higher precise solutions. The route-based algorithms were reported to have a fast convergence speed to high precision. Thus, a new method is proposed to improve the route-based algorithms by eliminating the dependent routes in the set of active routes. The modification is carried out on the well-known projected gradient (PG) algorithm. According to the numerical experiments, the improved algorithm is demonstrated to be nearly two times faster than the original version, and is more space-saving. Other features are also analyzed from the results.
