Toll Competition Among Congested Roads

Pricing Toll Roads under Uncertainty

We study the toll pricing problem when the non-toll costs on the network are not fixed and can vary over time. We assume that users who take their decisions, after the tolls are fixed, have full information of all costs before making their decision. Toll-setter, on the other hand, do not have any information of the future costs on the network. The only information toll-setter have is historical...

Effect of Off-peak Hour Toll Reduction on Toll Roads

Managing the Nepa Process for Toll Lanes and Toll Roads

The Practitioner's Handbooks are produced by the AASHTO Center for Environmental Excellence. The Handbooks provide practical advice on a range of environmental issues that arise during the planning, development, and operation of transportation projects. The Handbooks are primarily intended for use by project managers and others who are responsible for coordinating compliance with a wide range o...

Competition and Efficiency in Congested Markets

We study the efficiency of oligopoly equilibria in congested markets. The motivating examples are the allocation of network flows in a communication network or of traffic in a transportation network. We show that increasing competition among oligopolists can reduce efficiency, measured as the difference between users’ willingness to pay and delay costs. We characterize a tight bound of 5/6 on e...

Private Roads: Auctions and Competition in Networks

This paper studies the efficiency impacts of private toll roads in initially untolled networks. The analysis allows for capacity and toll choice by private operators, and endogenises entry and therewith the degree of competition, distinguishing and allowing for both parallel and serial competition. Two institutional arrangements are considered, namely one in which entry is free and one in which...
