The Colorado Department of Transportation (CDOT) conducted an operational pilot of the Road Usage Charge (RUC) concept as a possible transportation funding replacement to the state gas tax. The Colorado Road Usage Charge Pilot Program (RUCPP) involved a total of 147 participating vehicles that used one of three mileage-reporting mechanisms to record miles traveled and simulate fees based on that travel. Overall support for the operational pilot and the RUC concept itself remained high among pilot participants and there were no major technical issues encountered. A number of policy-related issues were identified throughout the course of the pilot. This report provides a summary of the RUCPP.
