Helsinki records zero traffic deaths for full year

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.

I live in helsinki and nowhere it is 20 kmh that I know of. Might be some random streets in center. And 30km/h streets are smaller living streets that driving that speed comes almost automatically.

Major ringways and main roads are 80 kmh btw

I have driven in many many countries - Helsinki does not feel slower than any place I have driven, faster in fact because there rarely are traffic jams

I reckon he means that the average speed when driving through the city centre is 21 km/h, given that you’re stopping at lights and stuff.

The Tom Tom data is interesting, but time taken for 10 km is not really an appropriate metric. In a more densely populated city, journeys are likely to be shorter.

> When you lower the speed limit, the average will also go down?

Yes, but by much less than OP might naively expect.
