The Transportation-Energy-Emissions Model (TEEM) was developed to study the varying effects upon energy use and air quality due to the implementation of several alternate traffic systems in a metropolitan area. Given certain information on number of persons using each part of the transportation system, time allocation of use, modal split, and certain characteristics of the transportation system, it estimates energy use and emission of SOx, NOx, CO, and HC. Emphasis of this study is based on the fact that the way a system is used affects energy use and pollutant emissions, and demonstrates how the volume of flow affects energy-emission rates by automobile, bus, and BART-type train use. Tentative results indicate that: (1) during peak congestion periods, arterial road use implies higher rates of fuel consumption than freeway, but during off-peak periods the situation is reversed; and (2) switching 30 percent of passenger miles from auto to either buses or trains improves the energy use and emissions situation significantly.
