Implementation and Analysis of Epoke Research

With an annual expenditure of approximately $50 million (inclusive of labor, equipment, and materials), the single largest cost item in the maintenance budget for Ohio Department of Transportation (ODOT) is snow and ice control. ODOT strives to provide an adequate level of service to the motoring public, which is measured by regain time or the amount of time to recover after a snow event by increasing the vehicle speed to within 10 miles per hour of the speed limit. The Epoke Sirius S4902 AST Combi Bulk Spreader (Epoke) is a type of material spreader used for winter maintenance activities. Recently, a research project was conducted (SJN: 134651) that demonstrated the potential for financial savings and efficiency improvements through the incorporation of the Epoke into winter maintenance operations. The previous study demonstrated that the Epoke is capable of spreading salt and brine up to three lanes wide and found it could reduce salt usage by 12%. When determining the costs savings and payback period of the Epoke, the researchers only considered the realized savings. There may actually be other costs savings that arise from the use of the Epoke, including roadway user savings, delay savings, and crash reduction savings. To ensure the Epoke is utilized appropriately, an implementation study has been commissioned to focus on four objectives: (1) validate the 12% salt savings estimate, (2) confirm the deployment strategy for the Epoke developed in the initial study, (3) estimate the cost savings of the Epoke including indirect user costs, and (4) develop a strategy for an ongoing evaluation of the Epoke by ODOT. Winter maintenance is a time- and resource-intensive task for ODOT. This implementation study will provide increased insight into the benefits and implementation of the Epoke. The results may include a cost savings associated with the Epoke, indirect user savings, and an implementation plan that shows how to best utilize the Epoke system. ODOT will also be provided with a method for tracking the future savings associated with the Epoke to ensure the appropriate use of the equipment to receive the maximum return on investment.
