Car use efficiency

This indicator shows the average occupancy during car trips.

1.8 passengers/car

Over the years, an average of 1.8 people sit in a car. This number has decreased slightly.

What do we see? 

Between 2010 and 2022, we see that the number of occupants in cars is around 1.8 people. This number has decreased slightly: at the beginning of the measurement period, it was around 1.84 while in recent years it is around 1.78. The high value for data year 2019 may concern an outlier.



What’s the aim?

In a circular economy, we aim to maximise car occupancy. Carpooling is effective because a car journey with more occupants is more efficient than meeting the same mobility needs via individual journeys, primarily in terms of fuel consumption. If carpooling becomes more established as a mobility option, it can also play a role in reducing the size of the car fleet.

What does this indicator measure?

This indicator shows the average occupancy rate of all trips by car as reported in the Travel Behaviour Survey organised almost every year from the Department of Mobility and Public Works.
