from the New York Times 9th annual year in ideas

Copenhagen has begun to create a system of as many as 15 extra-wide, segregated bike routes connecting the suburbs to the center of the city. The Bicycle Office of Copenhagen’s design calls for service stations (with air pumps and tools for simple repairs) and plans to employ so-called intelligent transportation systems — not unlike the technology that makes the E-ZPass possible. Using handlebar-mounted RFID or GPS technology, for example, commuters could detect other riders on the routes, helping them to assemble into pelotons or “bike buses.” These groups could in turn emit signals that trip traffic lights in their favor, resulting in a “green wave” of bicycle momentum.
