SPR-4861: Updating Cost Allocation and Revenue Attribution

Indiana’s road expenditures are financed primarily by highway user fees. The basic principles of highway financing are user-fee equity and statewide revenue adequacy. It is only through analysis of past costs and revenues that Indiana can develop an equitable pricing structure for its road users and an efficient revenue generation system to cover expenditures. Such studies are needed periodically to ensure user equity and revenue efficiency keep pace with changing travel demand and distributions, construction technology and materials, and above all, new/emerging vehicle technologies including electrification. This proposal is based on a request made to Indiana Department of Transportation (INDOT) by Indiana’s Legislature, to update Indiana’s 2016 Cost Allocation Study. The goal is to measure/predict/address the impacts of alternative-fuel technology (particularly, electric vehicles) on Indiana’s highway revenue adequacy and equity.
