The authors explore the properties of various types of public and private pricing on a congested road network with heterogenous users allowing for elastic demand. Heterogeneity is reprensented by a continuum of values of time. The network consists of both serial and parallel links, which allows...

Some road-pricing demonstrations use an approach called "value-pricing", in which travelers can choose between a free but congested roadway. Recent research has uncovered a potentially serious problem for such demonstrations: in certain models, second-best tolls are far lower than those...
