A Before-and-After Guide to Safer Streets

EDITOR'S NOTE: I think this one in particular might be a good solution to some of the wide, one-way streets in Columbus, such as Spring, Long, 3rd, or 4th.

3. Make the invisible visible. Clear sight lines can improve a street's safety significantly. Curbs lined with parked cars can make it hard for a turning vehicle to see what's in another part of the street. That problem can be addressed by removing some of the parking spaces closest to the corner — a process called "daylighting," which increases visibility considerably (so long as parking enforcement is strict). Curb extensions that bring pedestrians further into the street have a similar effect.
