This report summarizes the findings of a recent extensive study to determine the energy savings of TSM actions taken or planned in New York State for 1978-80. For those actions planned for implementation by 1980, both the direct energy savings and energy costs of construction and maintenance were quantified. The main determinants of an action's savings are its effect on vehicle-miles-of-travel and travel speeds. These changes were determined through various methods, including assignment-based techniques, traffic flow approaches, use of transit fare and service elasticities, and case study reviews. Energy costs resulted from the manufacture, construction, installation, operation and/or maintenance of the facilities and equipment required for each action. The analysis found net energy savings of 22.9, 25.5, and 28.1 million equivalent gallons of gasoline for 1978, 1979, and 1980, respectively. These figures represent approximately 0.5% of the total annual gas line consumption in the State. Those actions which conserve the overall largest amounts of energy are: traffic operational improvements, ridesharing activities; amentities for transit passengers; computerized traffic control systems; improved transit marketing; reduced off-peak transit fares; and park-and-ride services. Certain other TSM actions, inlcuding demand responsive transit services and express bus services, have a negative net energy impact. On the average, energy costs represent approximately 15% of energy savings. Energy savings occur in all urban areas of the State with 65% of the savings found in the New York City region. /Author/
