【摘要】 在拥挤的城市交通网络中,当考虑所产生的尾气污染总量时会出现反常现象,即.对交通网络的所谓“改善”可能反而导致尾气总量的增加。Nagurney(2000)用具体的例子阐述了三种不同的尾气污染悖论现象,并建议在交通网络设计问题(NDP-Network Design Problem)中,采用有效的定量分析方法以避免尾气污染总量的增加。本文首先利用备用能力(reserve capacity)概念和尾气污染总量控制思想,建立了两个等价的NDP双层规划模型,该模型能够同时消除这三种尾气污染悖论;然后,我们把Meng等人(2001)提出的算法进行推广,给出了本文模型的求解算法.最后用一个网络例子验证了本文模型与算法的有效性。更多还原

【Abstract】 Paradoxical phenomena can occur in congested transportation networks as regards the total emissions generated, which demonstrate that so- called ’ improvements’ to the transportation network may cause increases in the total emissions. Nagurney (2000) identified three distinct emission paradoxes through specific illustrative examples. In this paper, firstly, two alternative bi - level programming models for the network design problem (NDP) are established by using reserve capacity concept and total emissions control thought, which can avoid the three emission paradoxes effectively. Then an extended algorithm based on the algorithm proposed by Meng et al. (2001) is proposed. Finally, the proposed approach is illustrated through a network example.更多还原
