Red lights are the momentum-sucking bane of any bicyclist—they add time to the trip and kill your physical efficiency (just ask a physicist!). But thanks to some weird, animal-based technology in the Netherlands, riders may soon be able to sail through the city on a magic wave of green lights without having to worry about stopping for cars.
Flo, a traffic system that went into place last week in Utrecht, is a tall, blue kiosk abutting a bike path. Using sensors, it determines cyclists’ speed from hundreds of feet out and displays several kinds of symbolic advice. If cyclists need to speed up to catch a green light at the next intersection, they get a hare (not to be confused with a rabbit).
