在Venigalla的基础上，我们主要构建了考虑排放效应的多类别、多模式非加性路径成本交通分配模型。然后，我们使用基于路径的梯度投影（GP）算法来求解我们提出的数学模型。之后，我们将该模型和GP算法作为数值实例应用到Charlotte网络中。特别地，我们在模型中考虑了不同的网络结构和不同的位置，使其能够模拟道路上的车辆情况。通过与F-W算法的比较，可以看出GP算法比FW算法收敛速度快。结果还表明，GP算法可广泛应用于求解具有非加性路径代价的交通分配问题。
Based on Venigalla's work, we mainly constructed a multiclass, multimode nonadditive path costs traffic assignment model with emission effects under different engine operating modes. Then, we used a path-based gradient projection (GP) algorithm to solve the mathematic model we put forward. After that, we applied the model as well as the GP algorithm into Charlotte network as a numerical example. In particular, we considered different network structures and different locations in the model so that it can simulate on-road vehicle situation. Compared with the F-W algorithm, it can be shown that GP algorithm has a rapid convergence speed than FW algorithm. The results also demonstrate that GP algorithm could be widely used in solving the traffic assignment problem with nonadditive path costs.
