Drive cycles are stereotypical vehicle journeys representing typical motor vehicle trips in a given study area. This paper will concentrate on the derivation of drive cycles that will represent typical driving for Adelaide, in this way allowing accurate and reliable emissions models to be developed for studies of air quality and greenhouse gases. Highly detailed analysis of driving in Adelaide was performed using second by second time, position and speed data collected from GPS receivers in the vehicles. This allows for a very detailed statistical analysis of what a typical drive is. Furthermore the level of detail of the data allowed the typical drive to be disaggregated further into peak period driving and inter peak driving. The results showed quantifiable differences between the stop start nature of peak period driving and the more free flowing nature of interpeak driving. These factors have large influence on total vehicle emissions, hence a much better understanding of the contribution of traffic emissions throughout the day can be considered.
