Arrest means waiting for the crime to be committed. With a combo of curbs, roundabouts, speed bumps, road/street narrowing you redesign the street to disallow such behavior by default. It's like putting a crosswalk far away from a bus station. It's a design that encourages ppl to illegally cross the street since crosswalk is far away. Instead you redesign the street/crosswalk in such a way that by design there's no more need to break the law. Or if you hate pedestrians you put a big fence that's impossible to cross unless you use crosswalk- again, a design that makes breaking the law hard/not relevant
