STUDY OF ENTRY/EXIT EFFECTS ON NETWORKS WITH PRIVATE HIGHWAYS

摘要

Lots of researches focused on networks with toll roads these years. However, a problem emerges that the inefficient entries/exits of the toll roads may affect the equilibrium of the whole network. This paper is denoted to find out the quantitative effects of toll roads entries/exits. First, an abstract road network with toll roads is constructed, and the travel time functions of different kinds of links are gained. A user equilibrium model of networks with capacity constraints of the tolling sub-network's entries/exits is presented, and an Augmented Lagrangean Dual Algorithm is applied. Finally, a numerical example is given.
