ABSTRACT
This study is a complement to the report “Equity Effects of the Stockholm
Trial” (Transek 2006:31). The main focus of the study is how the equity
effects of a permanent congestion tax system differ among various groups of
citizens.
The amount of congestion tax paid varies widely. Most car owners in the
county pay congestion tax at least occasionally, but relatively few pay a lot:
about 4% of the privately owned vehicles in the county – corresponding to
about 1.2% of county residents - accumulated a total cost of SEK 200 or
more during one two-week study period, but that 4% accounted for one third
of revenues from privately owned vehicles. Thus, a large proportion of
congestion tax payments are paid by a relatively small number of drivers.
The study presents the average effects for various groups – but variations
within groups are substantial.
If one looks at the groups that pay the most congestion tax on average, the
statistics show that:
- Residents of the inner city and Lidingö pay nearly twice as much per
person as residents of other areas
- Households with high discretionary income (income/household
member) pay nearly three times as much as households with low
discretionary income
- Employed people pay about three times as much congestion tax as
others
- Men pay about 50% more than women
- Households with children pay more congestion tax; households
made up of two adults pay more congestion tax (per person)
How revenues are used largely determines overall equity effects – the
differences in the distribution profile of equity effects among various
possible revenue uses are often greater than the difference in the distribution
profile for the actual congestion tax.
