Stockholmers opposed the charge before they had lived with it. The 2006 trial cut cordon traffic about 22% against a 10–15% target, the referendum that followed said yes, and the cameras stayed on.

A congestion charge Stockholm's voters backed in a 2006 referendum. After a 2006 trial cut cordon traffic far more than forecast, Sweden made the ANPR-camera charge permanent in 2007 to ease inner-city gridlock; its revenue was earmarked for road investment. Most residents opposed it at first; it later won lasting majority support.

Live 📅 since 2006

📊 Impact

Cordon traffic fell about 22% during the Jan–Jul 2006 trial, against a 10–15% target, cutting queue times 30–50%. A September 2006 referendum in the City of Stockholm backed the scheme (53% of valid votes), and it became a permanent national congestion tax on 1 August 2007. Five years on, the traffic reduction had held and grown slightly once external factors were controlled for. A 2016 increase went partly to financing the Stockholm Metro extension; in 2026 the charge was capped at 135 SEK per vehicle a day.

🎓 Lesson

Run a real, honest pilot first — public support for congestion pricing tends to arrive only after citizens actually experience the freer-flowing, cleaner streets it produces.

Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Slides by Staffan Algers of the trial's evaluation expert group give the target (cut traffic on the most congested roads by 10–15%), the result (20–25%) and 30–50% less time in morning-peak queues; Börjesson et al. give 20–22% for March–June 2006; the peer-reviewed overview confirms that congestion fell more than anticipated.
Caveat
The 22% is the Swedish authorities' headline figure; the five-year evaluation gives 20–22% for March–June 2006 after a 28% overshoot in January, and the evaluation group's slides give 20–25%. The peer-reviewed overview's abstract confirms the effect was larger than anticipated but its figures sit behind the publisher's paywall.
