Speed is not the enemy, but it can be deadly and detrimental to our cities when applied improperly; it’s time we fixed that.
Safe Systems determines the right speed to design for by considering the vulnerability of humans, so that if a collision occurs, it’s much less likely to be severe.
Design speed has a profound effect on our communities. Impacting far more than just safety, design speed influences urban design, walkability, public health, and even traffic lights.
When engineers and policymakers decide a speed to design for, they are also pre-determining the character of the roadway, who it’s going to be built for, and who will be excluded.
We can all recognize a road that feels like it’s meant for fast or slow travel, but what are the actual design elements that create this environment?
