Project - GEORGIA: Simulation of Pricing on Atlanta's Interstate System

The objective of the simulation was to assess the effects of converting fixed automotive insurance costs into variable driving costs. The research monitored one full year of baseline travel activity for approximately 285 participating households. Approximately 500 vehicles in these households were equipped with instrumentation that monitors the second-by-second vehicle speed and position for every trip. Travel diaries and employer commute options surveys were also collected from each participating household and employer (as well as from a control group). In Phase II of the study, the impact of mileage-based insurance incentives was examined. The third of the study was delayed. It was supposed to examine simulate freeway congestion pricing schemes. The research team was to monitor the changes in driving patterns and use statistical analyses of household characteristics, vehicle travel, and relevant employer survey data (parking costs, transit accessibility, etc.) to examine the relationships between the incentives offered and subsequent travel behavior changes. Phases II and III were expected to provide extensive data for the first time on how commuters respond to various types of pricing policies.
