| Per person travel time in Great Britain, 1985/86 | 0.92 |
| Excluding age group of 0 to 11 years (• 1.06) | 0.98 |
| Complete travel reporting (• 1.09) | 1.07 |
| CATI method (• 1.07) | 1.15 |
| Per person travel time in the Netherlands, 1985 | 1.21 |
Note: Rough adjustments to the Great Britain survey for the age group not reported in the Netherlands survey, degree of travel reporting, and computer-assisted telephone interview (CATI) technique lead to a travel time budget similar to that of the Netherlands.
