"CPI" means the Consumer Price Index - U.S. City Averages for All Urban Consumers, All Items (not seasonally adjusted) as reported by the U.S. Department of Labor, Bureau of Labor Statistics; however, if the CPI is modified such that the base year of the CPI changes, the CPI shall be converted in accordance with the conversion factor published by the U.S. Department of Labor, Bureau of Labor Statistics, and if the CPI is discontinued or revised, such other historical index or computation approved by the Commission shall be used for purposes of this section that would obtain substantially the same result as would have been obtained if the CPI had not been discontinued or revised.
"Materially discourage use" means to cause a decrease in traffic of three or more percentage points based on either a change in potential toll road users or a change in traffic attributable to the toll rate charged as validated by (i) an investment-grade travel demand model that takes population growth into consideration or (ii) in the case of an investigation into current toll rates, an actual traffic study that takes population growth into consideration.
"Real GDP" means the Annual Real Gross Domestic Product as reported by the U.S. Department of Commerce, Bureau of Economic Analysis.
Any application to increase toll rates shall include a forward-looking analysis that demonstrates that the proposed toll rates will be reasonable to the user in relation to the benefit obtained, not likely to materially discourage use of the roadway, and provide the operator no more than a reasonable return. Such forward-looking analysis shall include reasonable projections of anticipated traffic levels, including the impact of social and economic conditions anticipated during the time period that the proposed toll rates would be in effect. The Department shall review and provide comments upon the analysis to the Commission. Notwithstanding any other provision of law, the Commission shall not approve more than one year of toll rate increases proposed by the operator.
