Travel per person by car availability and by mode (source: National Travel Survey 2006
Table 5.2)
Income is the biggest single factor differentiating the population in terms of
distance travelled but not in the proportion by car. Members of households in the
highest income quintile travel over 11,500 miles a year on average of which 80% is
by car. Members of the lowest quintile travel about 4,100 miles a year of which nearly
70% is by car. Car mileage will also be influenced by whether the cars available to a
household are company owned. The average mileage of company cars is 2.3 times that
of privately owned cars. Significantly this ratio applies not just to total mileage but to
commuting mileage as well.
Car availability has a greater influence on distance travelled than via trip-making
alone. People who are main drivers in households with cars travel 10,100 miles a year
whilst at the other extreme people in households without cars travel only 3,000 miles.
On average men travel 1,600 miles a year further than women, mainly arising from
differences amongst drivers in car-owning households. Although, as one would expect,
there is a wide variation in the distance travelled by car depending on people's car
availability, there is comparatively little in the absolute distance by public transport.
In particular 'other drivers' in car-owning households travel almost as much by public
transport as members of non-car-owning households (Figure 2.10).
