"American communities are at a crossroads. Transportation and related land use decisions are central to building healthy places for healthy people. The past decade has seen a notable rise in demand and opportunities for people to walk and bike, shared cars and bikes have quickly become a staple of metropolitan life, and many cities are now growing substantially around walkable neighborhoods and transit access. Small towns and rural communities are also seeking ways to increase walking and biking, largely for economic and health reasons. Auto-centric community design is still the norm, but we are seeing more exceptions to the rule and newfound willingness to address tough issues, like speed management and parking requirements. Further, communities are now beginning to grapple with potentially disruptive technologies, such as automated vehicles, which could support or undercut trends favoring human-centered mobility."
