Illustrated comparison inspired by the place and case. Conceptual scenes, not a photographic before and after.
How the change works
- 01 / Public decision
Speed, junctions and protections
- 02 / Physical change
Less exposure to serious collisions
- 03 / Possible outcome
Pedestrian and cyclist safety
Safety depends on several elements: geometry of intersections, speed, controls, vehicles and rescue.
Research and local documents ↓What the evidence tells us
Helsinki recorded no deaths among pedestrians in 2019, amid a decades-long decline in road fatalities.
Conditions and limits
That year, however, three people died in traffic. A year at zero does not guarantee permanent security nor does it measure a climate benefit.
Other possible benefits
More autonomy and confidence in daily travel.
