Implications of Marginal Cost Road Pricing for Urban Travel Choices and User Benefits
A model that combines origin-destination, mode and route choice into a single, consistent formulation and solution method is used to analyze the effects of marginal cost pricing of roads in the Chicago region. The solution of the system-optimal version of the model corresponds to minimizing the total cost of travel, subject to behavioral and definitional constraints. These results are compared to the standard user-optimal version of the same model and interpreted in graphs showing the effects of variations in total travel demand during the morning peak period, as well as the effect of alternative road pricing strategies.
