Highway expansion projects in large metropolitan areas are usually contentious. What are the full effects of highway capacity gains and who wins and who loses. This research elaborates our earlier network impact modeling work in two important directions. First, we extend our modeling capability to include highway lanes that are tolled. Second, we apply the new model to an important prototype application, the (recently) private 10-mile segment of California SR91. The possible widening of this route via extra tolled or extra general-purpose lanes has been the subject of considerable controversy. We show that our approach can shed light on key elements of such controversies and, thereby, possibly reduce political conflict and misunderstanding. We also show that whereas congestion tolls are widely presumed to be efficient, the efficiency outcomes are complex when only a very small part of the network is tolled.
