Helsinki records zero traffic deaths for full year

Someone has to put a chart near it, describing the decline in driving in the city. When you're limited to 30kmh, you might as well get a scooter...

https://www.tomtom.com/traffic-index/ranking/ 30 km/h is equal to 20 min/10km, 50 km/h is 12 min/10km.

So Helsinki city center is at 21km/h travel speeds, metro area at 31km/h. A speed limit of 30 km/h doesn't really affect these travel times much.

I can't find 2023 data to compare, however by other data on the net these are very common average speeds for any city in Europe even those with plenty of 50 km/h speed limits.

If more people take up public transport, bikes or scooters in fear of an average travel speed reduction of 1-2 km/h - that is a total win for everyone involved including drivers.

Average speed means you have both above and below speeds? When you lower the speed limit, the average will also go down?

But yes, in a city cycle time of traffic lights has a larger effect than max speed.
