enforcement

New York City's speed cameras are an unqualified success, but they still need to be renewed.

The problem of cars evading speed, red-light and bus-lane cameras with defaced or covered plates has gotten markedly worse — with more than 7 percent of plates that triggered automated enforcement cameras last summer proving to be unreadable.

Simple messaging changes can help transportation leaders win over residents who are skeptical of automated enforcement, a new study finds — and there's even more they can do to make those programs equitable, effective, and deserving of public support.

Imagine a world where every cell phone in every pocket in America could be instantly transformed into a portable traffic camera, capable of issuing misbehaving motorists a ticket with little more than a few swipes on a touch screen.
