By Charles Pekow — A Complete Streets project in Pittsburgh doubled or nearly tripled bike traffic while reducing auto trips. That's what an evaluation of a corridor found. Morning bike traffic went up 160 percent and evening use a whopping 280 percent. Part of the increase, though may have come from changes in transit culture as well as adding bike lanes on the road, says Travel Impacts of a Complete Streets Project in a Mixed Urban Corridor, the final research report of Carnegie Mellon University's Mobility21, a National University Transportation Center for Mobility sponsored by the US Department of Transportation.
Not only did cycling increase, but reduced traffic meant bike riders breathed cleaner air. And the number of accidents didn't climb. But more long term monitoring is needed to evaluate safety, the researchers found.
