According to the standard model of urban traffic congestion and urban spatial structure, congestion tolling results in a more concentrated city. In recent years, a new model of rush hour urban auto congestion has been developed which incorporates trip-timing decisions: the bottleneck model. In...

It is often argued in the US that HOV (high occupancy vehicle) lanes are wasteful and should be converted to HOT (high occupancy vehicles and toll lanes). In this paper, we construct a simple model of commuters using a highway with multiple lanes, in which commuters are heterogeneous in their...

Suppose that there are two congestible modes of travel from A to B - road and rail for concreteness - which are imperfect substitutes in demand. Road congestion from A to B is underpriced; this is an unalterable distortion. Compared to the first best, should the transportation planner choose a...

This paper presents a downtown parking model that integrates traffic congestion and saturated on-street parking. We assume that the stock of cars cruising for parking adds to traffic congestion. Two major results come out from the model, one of which is robust. The robust one is that, whether or...

Economists' favorite remedy for traffic congestion is road pricing. Not only is road pricing based on sound economic principles, but also given current technology it could be implemented at reasonable cost and in a flexible and sophisticated manner. But there are serious obstacles to the...

This paper discusses uniqueness and efficiency of user equilibrium in transportation networks with heterogeneous commuters. Daganzo (1983, Transportation Science) proved the uniqueness of (stochastic) user equilibrium when commuters have heterogeneous tastes over possible paths but identical...
