This section of the IPD Road Pricing Revenue website provides access to nearly 30 technical reports prepared for a variety of road pricing studies conducted around the United States in the past decade. The reports have been categorized by the eight tolling types shown in the links below. Within these sections, the reports are listed alphabetically by state. If multiple reports are available for individual projects they are listed chronologically. In all cases the links to the reports themselves are accompanied by a paragraph providing a detailed description of the contents of the reports to help users of the IPD website determine whether they would be interested in viewing the reports.
