ROADWAY DECISION MAKING AND IMPLICATIONS FOR ENERGY USE: SOME ECONOMIC CONSIDERATIONS

Energy costs are discussed in relation to the many other factor costs that are considered as a part of the complex resource allocation problem that is at the center of every roadway design problem. Efforts (housekeeping measures, non-output-related investments, capital turnover) now under way to conserve energy in the industrial sector are considered and similarities between this area and those in the roadway area are suggested. Potential areas for saving roadway energy are distributed between actions involving capital use and factor substitution and measures to stop waste through little or no use of capital. In this category, ways to change procedure and thereby reduce energy use are listed and include; judicious use of maintenance vehicles; minimize double handling during construction; reduce frequency of maintenance operations; and minimize waste of materials. In the factor substitution category are direct substitutions of capital for energy as well as more subtle forms of substitution of one material for another. Examples are listed of possible material substitution decisions with consequences for first and life-cycle energy costs. The dependence of product prices on the energy prices is discussed and a set of calculations is provided for energy price increases associated with President Ford's 1974 proposed deregulation and tax program. It is pointed out that energy use considerations requirea broad look at several implications.
