Impact of driving styles on exhaust emissions and fuel economy from a heavy-duty truck: Laboratory tests

This study focuses on the impact of the operator's driving style on emissions and fuel efficiency. Three styles were used in conjunction with the standard 5-mile cycle driving test procedure, with acceleration rates modified accordingly. The original cycle represented the 'aggressive' driving style, with 100% of the available vehicle acceleration rate. The 'normal' and 'technical' styles were assumed to use 60% and 30% of the maximum vehicle acceleration rate. The results are qualitatively expected in terms of the relative magnitudes for the three driving styles. However, they show significant quantitative differences in emissions and fuel consumption among the three driving styles, that suggest the modification of the operator's habits, if the 'technical' driving could be part of intelligent transportation systems.
