| 摘 要： | 给出一种考虑排放约束条件下的交通分配均衡模型,在所定义的广义出行费用中明确考虑捧放因素.通过将变分不等式同题转换成等价的最优化问题.引入改进投影算法求解该模型.在所给出的数值算例中考虑两类对排放不同偏好的用户,采用均衡算法求解二次规划子问题,所得的弧及路径最优解收敛.且均满足Wardrop平衡条件.

| Abstract: | This paper presents a traffic assignment equilibrium model considering emission effects.The model explicitly introduces emission proportion in the generalized costs.By inverting the variational inequality problems into an equivalent optimization problem,an algorithm called modified projection method is adopted.Meanwhile,two classes of travelers are considered in numerical example,which have different emission preference.Using the equation algorithm,the quadratic programming subproblem is solved by iteration... |
