Improved method of driving cycle construction for urban bus

An improved method is developed for urban bus driving cycle construction.Driving condition data are collected on the representative routes which are selected between the major residential areas and commercial or industrial areas according to the traffic flow.The micro-trip is defined as a trip between two bus stops.A driving cycle is then constructed with the randomly selected micro-trips according to the proportion of the driving condition.The representative urban bus driving cycle is selected by the variation of the parameter mean value.The improved method of urban bus driving cycle construction and the synthesized Dalian urban bus driving cycle are both verified with the case study of urban bus in Dalian.Driving cycle by the improved method provides the design references for the measurement of pollution and fuel consumption on the electric vehicles which are developed with the characteristics of urban bus.
