Abstract:Nonlinear pricing refers to a case in which the price or tariff is not strictly proportional to the quantity ; purchased. While economists have studied nonlinear pricing for quite some time, its application to road pricing ; is relatively unexplored in the transportation literature. The number of articles on nonlinear road pricing is few, ; and many address only its impacts via empirical evidence. There has been little attempt to determine an optimal ; nonlinear pricing scheme, e.g., that maximizes the social welfare, especially for large road networks. ; The objective of this research is to develop methodologies for determining optimal nonlinear road pricing ; schemes for realistic road networks and explore its impacts, e.g., on congestion, equity, and other factors. ; In this study, we establish new results concerning nonlinear road pricing. In particular, the conditions under ; which link-based equilibrium conditions exist are of particularly importance in theory. New and efficient ; algorithms for determining optimal pricing structures are developed. These algorithms are useful to various ; transportation agencies and private companies in developing and analyzing nonlinear pricing schemes for the ; roads under their jurisdiction.
