FUEL SAVINGS POTENTIAL OF LOW-COST TRAFFIC ENGINEERING IMPROVEMENTS
The objective of this project was to develop priorities for certain low-cost urban traffic engineering improvements based on their potential for saving fuel. The study procedure involved the use of a test vehicle equipped with a precision fuel meter. Test runs were conducted on selected routes in Albuquerque and in offroad simulated conditions. Data from the field tests were processed with linear regression techniques to develop a model for the prediction of a rate of fuel consumption. The principal independent variable in the model is the rate of vehicular motion, although a correction for gradient is required to provide consistency between the model and the results of field tests. The model was applied to certain traffic improvements that could not be evaluated through before-and-after field tests. With respect to fuel saving, the most cost-effective improvements were found to be flashing signal operation, use of longer curb radii, and better use of existing coordinated signal systems and one-way streets. Pedestrian grade separations at school crossings cannot be justified solely on the basis of fuel savings, and the operation of neighborhood traffic diverters was found to result in an excess of fuel use.
