Consumer Response to Road Pricing : Macro and Micro Modeling Tools for Socioeconomic Evaluation and Pricing of Managed Lanes

This report summarizes the analysis of observed commuting changes after conversion of an existing carpool lane into a high-occupancy toll lane, on 15.5 miles of Atlanta I-85. The team explored the correlations between observed changes in travel behavior and the socio-spatial characteristics of the users using 1.5 million license plate observations coupled with census demographic data. Commuter response was evident in the observed changes in commuter choice to continue to use the new managed lane, or move to the general purpose lane after conversion. Aggregate-level socio-spatial analysis of the impacts of the Atlanta I-85 HOV to HOT conversion across demographic groups and socio-economic attributes are presented in this report. This study enhances the ability of modelers to integrate managed lanes into travel demand models, with respect to travel demand response across user characteristics. The report also introduces a comprehensive modeling framework for socioeconomic analysis of managed lanes. The methods developed through this can inform future Traffic and Revenue Studies and help to better predict the socio-spatial characteristics of the target market.
