How it Works

MISSION

A joint effort between the North American Council for Freight Efficiency (NACFE) and Rocky Mountain Institute, Run on Less is a best-of-the-best, cross-country roadshow that showcases advancements in freight efficiency. The goal of the Run is to highlight the best possible current use of the efficiency technologies, operational practices, and driver capabilities to show what the most innovative fleets can accomplish in the real world in terms of fuel economy and freight efficiency. Run on Less showcases how efficiency technologies improve the bottom line for fleets and benefit the environment by reducing greenhouse gas emissions.

Run on Less Regional will highlight how drivers and fleets deliver high efficiency in the movement of goods in regional haul applications - where the truck remains in a specific geographic region, no more than 300 miles from home.

MEASURING FUEL ECONOMY

Three main metrics will be reported throughout the Run: GALLONS, DOLLARS, & CO2 SAVED.

  • Gallons saved will be calculated by compari ng the fuel consumption of the Run on Less trucks to the amount of fuel they would have consumed if they all had the U.S. national average for like duty cycles. Various datasets were supplied to NACFE and used for this estimate.
  • Dollars saved is based on an average diesel price of $3.00 per gallon.
  • CO2 saved is based on the fuel savings and is presented in metric tons. Combustion of 100 gallons of diesel fuel emits 1.01 tons of CO2 into the atmosphere.

Miles per gallon will be calculated by combining two methods:

  • The first is by reading fuel - consumption data from the CAN bus using Geotab telematics devices installed on the trucks. CAN bus data via telematics is available in near - real time, which makes it useful for reporting over a specific period, such as for a day or a trip.
  • The second method is by tracking fill - ups. This method can be more accurate than the first method over a longer period of time since it tracks the actual fuel that goes into the truck.
  • The total truck average fuel consumption is cal culated by adding total miles driven by all trucks above a minimum threshold of 50 miles divided by total fuel consumed by those same trucks.
  • A day is defined as midnight to midnight Eastern Time.
  • Results are updated approximately once per hour.
  • Miles per gallon based on fill-ups will be compared to what the CAN bus data shows and an adjusting factor may be used on the CAN bus data for day-to-day reporting.

CONDITIONS

To portray the conditions drivers and their equipment are facing, in addition to MPG we will be showing some of the factors that are likely to affect fuel economy. These include the payload hauled, total elevation change, average vehicle speed, and other items.

  • Payload is estimated using two methods: Method one is from the bill of lading (reported by the driver). The second method is based on a calculation performed by Nevin Avenue LLC using telematics data and subtracting the tare weight of each tractor and trailer. Tare weights were measured by each fleet prior to the start of Run on Less.
  • Elevation data is collected from Google Maps based on GPS points provided by Geotab.
  • Average vehicle speed is calculated when the vehicle is traveling at speeds greater than 5 MPH.

REPORTING ONLY AVERAGE MPG

MPG and freight ton efficiency are only shown in daily and accumulated averages for all trucks. A goal of Run on Less is to highlight the effectiveness of the many different technologies, not to identify a ny specific ‘winning” combination. Also, the duty cycles are very different with re spect to payload, routes, stops per day, etc. making it unrealistic for comparisons.
