This paper was prepared to educate the transportation planner/engineer in some of the rudiments of ecology and with the hope of systematizing current approaches to ecological assessment. Considerations of energy, or bio-energetics, have been found to be singularly applicable to transportation impact assessment. This method of evaluating the effects of environmental impacting factors on environmental elements is outlined herein. The method can be applied to the analysis of the ecological impact of all types of activities, and with particular pertinence to transportation.

The energy theory is based on analysis of the amount of energy which is required by plants or animals or ecosystems or subsystems, to permit their growth or stability to continue. The numerical calculations involved permit quantification of impact effects of transportation facilities.
