Crosswalk Countdown Timers

Countdown timers on crosswalk signals have become so standard that most people don't notice them. But they represent a straightforward example of giving people the one piece of information they actually need: how many seconds until the light changes. Trust them to make their own decision about whether to cross. Before the timers, pedestrian signals showed a walking figure or a raised hand. The transition was abrupt. Now I can see 14 seconds remaining and decide whether to jog or wait. Visibility changes my behavior in a measurable way. Timers also reduce accidents because drivers waiting to turn can see the countdown and anticipate when traffic will move. Several studies have shown fewer pedestrian-vehicle conflicts at intersections with countdown displays. The interface is as minimal as possible: a number counting down inside the shape of a raised hand. It doesn't try to instruct or warn. It just provides data. The user interprets it based on their own speed, distance, and risk tolerance. Numbers are sized large enough to read from across the street, usually about 6 inches tall in high-contrast orange. Simplicity is why it works for every age and language group.
