COMPARISON OF ENERGY AND POLLUTION CHARACTERISTICS OF PROPULSION SYSTEMS OF DUAL-MODE TRANSIT VEHICLES AND THE AUTOMOBILE
A typical dual-mode trip was selected on which to base a comparison of energy consumption, energy cost, and pollution levels associated with the following vehicles and vehicle-transporter combinations: all electric bus on- and off-guideway, all electric bus using electric transporter on-guideway, diesel bus, diesel bus using electric transporter on-guideway, private automobile using conventional streets and freeways, private automobile on electric transporter on-guideway, and gasoline bus on- and off-guideway. The energy consumed in terms of raw energy sources does not significantly among the transit methods evaluated, since the overall system energy conversion efficiencies for these processes are approximately equal. Electrically powered transit methods operate at a lower cost and at much lower pollution levels than the petroleum-fueled internal combustion engine methods. Generating plant emissions are relatively easily controlled, and a lower cost fuel can be used in addition to having flexibility of fuel selection. Trip speeds were 12 mph (19.3 km/h) average off-guideway in the suburbs; 7 mph (11.3 km/h) average downtown; and 50 mph (80.5 km/h) cruise on the guideway.
