How this atlas is made · What “last verified” means · What “source-checked” means · The full record behind this page

A 1990 flat toll built for revenue only started pricing behavior in 2017 — rush hour and diesel cost more, electric cars far less. Whether that actually cut traffic is still an open question no one has independently checked.

Oslo has tolled entry since 1990, but only from 1 October 2017 did pricing become time- and emission-differentiated: rush-hour and diesel cost more, electric cars far less. A third ring, Indre Ring, followed in 2019. Fjellinjen — 60% owned by Oslo, 40% by Akershus county — now runs 83 stations across three rings.

Live 📅 since 2017

📊 Impact

There is one traffic figure and it belongs to the operator. Fjellinjen's economy director told Dagbladet that in the days before Easter 2018, half a year after the reform, crossings were down 4.5% on the same period in 2017 — and said himself that the raw March-on-March figure of 13.8% is mostly an Easter-calendar artefact. The behavioural response the tariff was built for faded fast: in the first three months after the new rates, crossings in the half hour from 06.00, just before the rush window opens, were up 8.2% year on year; by March 2018 that increase was 1.9%. The city's own climate accounting is blunter still — the Climate Agency writes that almost the entire effect of today's toll rates already sits in the reference trajectory, so its table of emission reductions counts only the later rate changes. The revenue side is not in doubt: 3,387 million kroner in 2020 rising to 4,680 million in 2024.

🎓 Lesson

A toll ring can be thirty years old and still be a blunt instrument, because the age is in the hardware and the pricing is the policy. Oslo's ring opened in 1990 and was fully automated on 2 February 2008 — neither of those dates changed what a driver pays for choosing a time or a fuel. That started on 1 October 2017, when a flat 34 kroner for every car around the clock became 44 off-peak and 54 in the rush for petrol, 49 and 59 for diesel. What happened next is the useful part. Drivers did shift their departure, and then they stopped: an 8.2% rise in pre-rush crossings in the first three months was down to 1.9% by March. Nobody has isolated the effect, because the reform raised the general rate at the same time as it differentiated, and the city's climate accounting treats today's rates as part of the baseline rather than as a measure with an effect to claim. What is documented is who pays: an analysis for the city found men pay more than women because they drive more, and middle- and high-income households more than low-income ones.

What the mapping says
Store norske leksikon dates Oslo's toll ring to 1990. Dagbladet states that on 1 October the previous year time- and environment-differentiated rates were introduced, so that a rush-hour crossing then cost 54 kroner for petrol cars and 59 for diesel against 44 and 49 outside the rush, where previously it cost 34 kroner for all cars around the clock.

Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Dagbladet quotes Fjellinjen's economy director Magne Liestøl Larsen: total March traffic was down 13.8 per cent against March 2017, but much of the decline is because Easter fell in March this year and April last year; looking at the days before Easter, traffic was down 4.5 per cent.
Caveat
A self-reported figure relayed by the press, not an independent evaluation; and the October 2017 reform combined time and emission differentiation with an overall rate increase, so no part of the change can be attributed to differentiation alone.
