SPR-4606: Overweight Divisible Loads: Permit Administration and Impact on Indiana’s Road Infrastructure and Safety

The study will provide information to Indiana Department of Transportation (INDOT) to support deliverables to the legislature. It will also determine the actual infrastructure performance at permitted routes; and identify any need to revise permit fees to incentivize user behavior. The study will measure the anticipated changes in infrastructure consumption due to any fee changes, document impacts of fee structures on shippers, and explore financial levers to facilitate permitting. Deliverables will include a permit Calculator (for carriers) to calculate benefits of axle addition, and a dashboard (for INDOT) to monitor permitting impacts. Finally, carriers will be surveyed for their perspectives and possible responses to future overweight (OW)-permitting initiatives.
