The Equity Effect of Road Charges: Calculating Lorenz Curve Differentials Through Sample Enumeration
In order to investigate the equity effect of road pricing, a realistic transportation network modeling exercise has been undertaken, simulating a first-best road pricing strategy as well as various second-best strategies as implemented in the Oslo toll ring. The model predicts trip generation, destination choice, mode split, and route assignment, separately for the peak and off-peak periods. Relying on the prototypical sample enumeration technique, the paper will subdivide the population in each zone into eight brackets defined in terms of household income per consumption unit. The paper will compute costs, benefits, and demand effects within each income bracket and show how equity impacts can be described in terms of differential Lorenz curves and Gini coefficients.
