Abstract
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.
