Copenhagen... began last month to create the real thing: a system of as many as 15 extra-wide, segregated bike routes connecting the suburbs to the center of the city. These are not bucolic touring paths; Copenhagen's bike highways are meant to move traffic. Nearly 40 percent of Copenhagen rides a bike to work. On Norrebrogade, a two-mile street in the center of the city, 36,000 cyclists clog the bike lane every day.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.
Virginia, under the leadership of Gov. Tim Kaine, became the first state to severely limit cul-de-sacs from future developments. New rules require that all new subdivisions attain a certain level of "connectivity," with ample through streets connecting them to other neighborhoods and nearby commercial areas.
