Walking (in 1971) has an energy intensity of 1,380 Btu/passenger mile (PM) and a labor intensity of 0.75 jobs/million PM. Additional food requirements to sustain the body while walking account for the direct energy cost and 10.4% of the total energy cost. An average walker, for purposes of this study, weighs 130-150 lbs., walks on a level surface at 2.17 mph, and consumes 3.3 calories or 13.2 Btu's per minute. Indirect costs include shoes, which measure 345 Btu/PM and .75 jobs/million PM… CONTINUE READING
