Independent driving pattern factors and their influence on fuel-use and exhaust emission factors

摘要

This study is aimed at finding independent measures to describethe dimensions of urban driving patterns and to investigate whichproperties have main effect on emissions and fuel-use. 62 drivingpattern parameters were calculated for each of 19 230 drivingpatterns collected in real traffic. These included traditionaldriving pattern parameters of speed and acceleration and newparameters of engine speed and gear-changing behaviour. By usingfactorial analysis the initial 62 parameters were reduced to 16 inde-pendent driving pattern factors.
