Abstract:

This paper recites a parable, formulates a model and devises an algorithm for optimizing tolls on a road network. Such tolls induce an equilibrium traffic flow that is at once system-optimal and user-optimal. The parable introduces the network-wide congestion pricing problem, intending to emphasize the significance of the variability of users' value of time and the importance of not restricting tolls to certain links a priori. The model permits the marginal value of time to be a random variable having a different distribution for each origin-destination pair. The algorithm provides what transportation planners have never had: the ability to determine the best toll for each link in the network. It can solve networks with thousands of nodes in reasonable time on a 486-class PC.
