If you?re a cyclist in Aarhus, Denmark, you may soon be able to pedal from home to work or school in the morning without stopping at a single red light. As part of a pilot program to encourage biking, the city has engineered a popular intersection to be responsive to cyclists. Riders will attach a tag on their wheel that triggers a sensor and turns the light green in their favour. By making the streets more bike friendly, city planners hope that they can cut car congestion and pollution.
