In earlier work a toll pricing framework for congestion pricing has been developed for both fixed and elastic demand traffic assignment models as an alternative to traditional marginal social cost pricing. It has also been extended to "second best" pricing, i.e., where tolls are disallowed on specified network links. Within the framework it is possible to define alternative objectives such as minimizing toll costs, minimizing the number of toll booths, etc. This paper will report the results of recent computational experiments on methods designed for various toll pricing objectives.
