A benefit/cost analysis method for evaluating transportation projects, where the base standard of value is net energy rather than the traditional monetary units, is described. Mathematical models and/or tables are constructed to estimate energy requirements for construction and equipment investments, operations and maintenance requirements, and road user requirements at the project level. The technique was applied to a bus/car pool systems demonstration project in Miami, Florida. Results showed considerable differences between the values obtained by the energy-based benefit/cost method and those obtained by an economic analysis. Assessment of car pool occupancy showed that a change from 3 to 4 persons per vehicle affected running costs only slightly relative to the do-nothing alternative (typically less than 3%). This indicated that the vast portion of energy savings achievable arises from the auto-to-bus shift. For constant speed situations, it was observed that fuel requirements typically made up about 80% of the total running cost energy. For speed change situations, the combined requirements of oil, maintenance, depreciation, and tire wear were about the same as for fuel. /HRIS/
