Results suggest that the relative connectivity of pedestrian and vehicular Have about 14% pedestrian mode share, and those with poor pedestrianĬonnectivity have the lowest proportion (10%) of pedestrian trips. Areas with high levels of both pedestrian and vehicle connectivity Relatively more direct to nearby retail and recreational destinations on foot Itįound the highest proportion of pedestrian trips (18%) in areas where paths are Puget Sound (Seattle, Washington area) urban neighborhoods (CMHC 2008b).

During the 1960s through the 1990s, roadway design practices favored More direct access to destinations than a network of one-way streets (GayahĢ012). Nonmotorized travel (Gayah and Daganzo 2012).
