A Study of Emission Modeling and a Path-Based Solution Algorithm in Traffic Equilibrium Assignment

Abstract

This paper mainly demonstrates a traffic assignment model with emission effects under different engine operating modes. In particular, it is a non-additive path costs traffic assignment model. Based on Venigalla’s work, we explicitly perfect the traffic assignment model with emission effects under different engine operating modes. In addition, we use a path-based gradient projection (GP) algorithm to solve it. We also apply the model as well as the GP algorithm into Charlotte network as a numerical example. Compared with the F-W algorithm, it can be shown that GP algorithm has a rapid convergence speed than FW algorithm. The results also illustrate that GP algorithm could be widely used in solving the traffic assignment problem with nonadditive path costs.
