PROPULSION SYSTEM PERFORMANCE REQUIREMENTS FOR GUIDED URBAN TRANSIT SYSTEMS

A methodology is presented for analyzing different performance levels, such as acceleration, deceleration, top speed and peak power to weight ratios, of transit vehicles. The optimization of these levels is desirable to attain certain performance objectives, including the maximization of travel time, capital costs, operating costs and energy consumption. Presented is a method which analyzes the trade-offs involved to achieve various levels of these objectives. The report describes the measures of propulsion system performance and the factors to be considered in their determination, and relates them to the design characteristics and parameters of a typical light rail transit (LRT) system. Additional factors which may affect the selection of performance parameters are discussed, namely the effect of curves, grades and spot speed restrictions. A set of values is recommended which could be used as design guidelines until more definitive studies can be performed on specific applications. /Author/
