| Abstract: | This paper discusses the optimal model of road toll under elastic demand. A bi-level
programming model is developed, of which the upper-level is aimed at minimizing the whole cost of
the road network, while the lower-level is satisfied with the equilibrium model based on elastic
demand. The model meets the principle of Wordrop equilibrium. A heuristic algorithm is proposed.
The proposed model and algorithm are illustrated with a numerical example. |
