چکیده مقاله
Recently, gradient projection GP has been extended as efficient algorithms for solving the traffic assignment problem TAP In this paper, two distinguished GP methods for TAP are investigated Theyare an algorithm to apply Bertsekas s GP method and an algorithm to apply Rosen's GP method They confront the problem in the same way, but with various descent directions and step sizes The efficiency of the algorithms is compared using large scale test networks Algorithms are developed ina same platform and compared based on the computational efforts for reaching given accuracies The results show that the algorithm using Bertsekas s GP converges more rapidly than another using Rosen's GP
