In 2016, the city of Odense, Denmark implemented a new form of technology to allow for more efficient bike travel. Often, when it is raining heavily, cyclists have had to sit in the rain for long periods of time at traffic lights, and this disincentives them to cycle to work that day. To fix this problem, Odense has placed rain sensors in traffic lights along their super bike highways. These sensors interact with motion detectors which “allow the system to register when bikes are within 70 meters of the intersection.” They then automatically prolong the green light. The intersection includes a small sign that explains the system to the cyclists, and when a light goes on, they can see the system is functioning.This technology allows cyclists to experience up to 20 seconds longer of green light, and makes their overall journey more efficient, safer, and dryer.
