Where trucks outscore passenger vehicles, the data suggests this may partly reflect off-peak scheduling and professional routing that reduces exposure to the most congested conditions.
Trucks idle at 8.5% of total fuel consumed, compared to 13.2% for passenger vehicles in the same city.
Dublin: the hidden passenger vehicle cost Dublin's 14-point truck advantage (truck score 57, passenger score 43) shows up most sharply in the idle data.
Amsterdam: a mixed picture Amsterdam's 10-point truck advantage (truck score 65, passenger score 55) holds at the overall level, but the fuel data introduces a complication.
Its trucks idle at 18.2% of total fuel consumed, the highest truck idle rate of any city, yet trucks still significantly outperform passenger vehicles on the overall efficiency score (truck score 46, passenger score 31).
