Measuring Toll Burdens: Applying Lorenz Curves to a Detailed Data Set of Users of Metropolitan Transportation Administration Bridges in New York City (11-2241)

This paper utilizes a unique survey dataset of toll revenue collection on New York City bridges administered by MTA Bridges. This dataset, which contains detailed information on road user income and location, is analysed to assess distributional equity of burden across road users of various toll facilities (both value priced and fixed rate tolls) in the New York/New Jersey region. The distributional impact is summarized using Lorenz Curves and Gini Coefficients, a standard economic measure, and through these and other measures the authors develop empirical estimates of the social equity conditions on the existing priced facilities. The authors find that burdens are least equitable on facilities where there are few alternative routes, more equitable on those with more alternatives, but that in general users of MTA Bridge facilities are higher income than the general population surrounding those facilities.
