3.00m wide lanes are safer than wider ones at the city

It is commonly accepted that drivers with more room tend to drive faster, hence collisions do more harm than those ones at a lower speed.

There is a new study confirming that 10-foot lanes (3.05m) make safer intersections, at least in Tokyo and Toronto.

The report also states that  traffic capacity in Toronto was actually highest for lanes right around 10-feet wide. “Traffic delays on urban roads are principally determined by junctions, not by midblock free flow speeds,” he writes. “Reducing lane width to 3.0m [~10 feet] in urban environments should therefore, not lead to congestion.”

So, why not reducing the width of the road and return that space to pedestrians or, even better, to cyclists? After all, adding bike lanes reduces traffic delays
