  16. 16. Implications for safety & access</li></li></ul><li>Driving & the Built Environment – the 5 D’s<br />Density Population & employment by geographic unit (e.g., per square mile, per developed acre).<br />Diversity Mix of land uses, typically residential and commercial development, and the degree to which they are balanced in an area (e.g., jobs–housing balance).<br />Design Neighborhood layout and street characteristics, particularly connectivity, presence of sidewalks, and other design features (e.g., shade, scenery, presence of attractive homes and stores) that enhance the pedestrian- and bicycle-friendliness of an area.<br />Destination accessibility<br /> Ease or convenience of trip destinations from point of origin, often measured at the zonal level in terms of distance from the central business district or other major centers.<br />Distance to transit<br /> Ease of access to transit from home/work (e.g., bus/rail stop within ¼ to ½ mile).<br />Ewing & Cervero, JAPA, Summer 2010 | TRB Report #298<br />

  27. 27. Draft FTA Policy – Connectivity Nexus<br />Key requirement for determining the eligibility of a pedestrian or bicycle improvement is whether it has a functional relationship to a public transportation facility.<br /><ul><li>Pedestrian Improvements – within one-half mile
  28. 28. Bicycle Improvements – within three miles</li></li></ul><li>Connectivity & Safe Streets<br />less safe<br />safer<br />Better connected cities are safer<br />Intersection Density (better measure)& Link-Node Ratio<br />Both measures – difficult for people to understand intuitively<br />Source: Wesley Marshall and Norman Garrick | New Urban News and CNU <br />
