本文讨论了交通排放外部性内在化的相关问题，在道路网络与固定的出行需求。除了边际社会成本定价（MSC）拥挤收费计划被认为是产生一个交通流分布的最小总行程时间为第一最好的。我们给出了一个反例表明，MSC和其他最好的拥挤收费计划并不一定会导致更少的交通排放。在不使用任何补贴的情况下，我们指出，总是存在一个收费计划，诱导交通流量分布与最小的排放量。我们还提供了一个约束的百分比减少交通排放量的任何收费计划，然后提供计算收费的方式，使决策者之间的权衡两个相互冲突的目标，缓解拥堵与减少交通排放量的方法。(c)2006爱思唯尔有限公司保留所有权利。
This paper addresses issues relevant to internalizing traffic emission externality on road networks with fixed travel demands. In addition to marginal social cost pricing (MSC) congestion pricing schemes are considered that yield a traffic flow distribution with minimum total travel time as first-best. We give a counterexample showing that MSC and other first-best congestion pricing schemes do not necessarily lead to less traffic emissions. Without using any subsidy, we indicate that there always exists a charging scheme that induces a traffic flow distribution with minimum emissions. We also provide a bound on the percent reduction in traffic emissions achievable by any charging scheme, and then offer methods for computing charges in a manner that allows decision makers to trade-off between two conflicting objectives, alleviating congestion versus reducing traffic emissions.
