Many transport and other service problems come down to simple network choices: what mode and/or route to take, when some of the routes and modes are congested and their use can be priced or not priced by different operators. The operators can have different objectives and face different market...

In this paper we study the problem of a city with access to two subcentres selling a differentiated product. The first subcentre has low free flow transport costs but is easily congested (near city centre, access by road). The second one has higher free flow transport costs but is less prone to...

This article introduces the contributions of this special issue on modelling of urban road pricing and its implementation. The issue focuses on the design of urban road pricing schemes, and their spatial and temporal impacts, using quantitative transport (and land use) models. The policy...

In this paper we study how trip chaining affects the pricing and equilibrium number of firms. We use a monopolistic competition model where firms offer differentiated products as well as differentiated jobs to households who are all located at some distance from the firms. Trip chaining means...

This paper develops a model for the monopolistic competition of subcenters for the shoppers and workers of a central city. The model is an extension of the de Palma & Proost (2004) model that is limited to the symmetric case. Inhabitants of a CBD can choose one of the subcenters to buy a...

This paper presents a spatial model to study imperfect competition with congestion. The model is used to examine the price and wage setting of subcenters of a city. Residents live in a city while they shop and work in subcentres. Each subcenter o.ers one di.erentiated product and one...

A proposal has been made to build a new tunnel under the Scheldt river near the centre of Antwerp in order to relieve traffic congestion on the ring road and in an existing tunnel. The new tunnel is expected to cost more than €1 billion, and tolls have been suggested to help finance...
