Abstract

Driving patterns, i.e. speed and acceleration profiles, have a large effect on emissions and fuel consumption. This study aimed at creating a typology of urban driving patterns and applying it on data of speed, acceleration and engine speed profiles etc. collected in real urban traffic. To obtain a typology of driving patterns cluster analysis was initially tested but was, however, found to yield unstable results. Instead a typology was built based on exogenous segmentation of speed, occurrence of speed changes, acceleration and stopping occurrences. Fifteen segments were found to cover more than 98 % of the total length, time of driving and exhaust emitted. The driving pattern types were described in terms of speed, acceleration, deceleration, speed oscillation, percentage of stopping,
