Variables and explanation of computation.

Measure	Unit	Methodology of calculation
Total energy consumption	kWh	Transform wattage and voltage information provided at 1 Hz intervals to kWh using power-law and energy equation.
Total distance	Miles	Sum of speed information (mph) provided at 1 Hz intervals is divided by the total duration of the run.
Average consumption per mile	kWh/mile	Total energy consumption of the drive is divided by the total distance.
Speed	Mph	Average speed for the run.
Driver	Categorical	Drivers were differentiated by unique IDs and then numbered.
Road type	Categorical	Road types were differentiated according to the definitions of the division of Statewide Planning [29].
