| 摘 要： | 在考虑环境因素的情况下将广义备用能力的概念与城市交通离散网络设计问题结合在一起,一方面要求整个交通网络可以容纳的OD需求量与车辆尾气排放总量之差最大;另一方面,通过在交通网络中添加新的路段来提高整个交通网络的OD需求量。文中给出了环境因素下城市交通离散网络设计问题中确定最大OD需求量的优化模型。在分支定界思想的基础上设计了求解该模型的启发式算法。最后,通过简单的算例,说明该算法是可行并且有效的。

| Abstract: | In this paper, we combine the concept of generalized reserve capacity with the d iscrete network design problem under environment objective. On the one hand we t ry to maximum the gap of the travel demand and the total amount of emissions. On the other hand, we construct new road in order to increase the whole OD demand of a road network. A programming model and the heuristic solution algorithm whic h base on the idea of the Branch and Bound are proposed to solve the model for m aximal OD travel demand in urban transport discrete network design problem under environment objective. The applications of the model and its algorithm are illu strated with numerical examples. |
