Network Congestion, Braess Paradox and Urban Expressway System

Résumé du livre

Some paradoxes, such as 'The Braess Paradox,' persist in transportation networks. This paper studies the congestion properties in networks constituted by a set of circular and diffusive expressways. We use a model with a single origin/multiple destination (E-net) to depict the evening rush hour, and one destination/multiple origin (M-net) to depict the morning rush hour. Some conditions for efficient equilibrium in such model are obtained. Policy recommendations such as capacity constraints/increases of key roads and differential parking charges are given.
