These are most often transit-oriented, pedestrian friendly, and senior friendly. This is partly due to the mobility options possible with higher-density and mixed-use development patterns. As Malizia (2005) said, “They help make multiple destinations more accessible to pedestrians, create public spaces convenient for social interaction, and locate residences close to the street to increase safety, and so on. Compared with traditional zoning, these outcomes can promote more sustainable and healthy development patterns.” New communities are being designed where the origin and destination of people’s trips are closer to one another. Sidewalks and streets with clear crossings and slower vehicle traffic are safer and easier for older people, families with children and baby carriages, and people with disabilities who may need longer time to cross. These characteristics are also entirely consistent with pedestrian-friendly and senior-friendly concepts (Ewing, 1999, Kocher 2005).
