While the prevailing assumption is that "livable"; street treatments, such as street trees, on-street parking, narrower lanes, and adjacent roadside development, have a negative impact on transportation safety, empirical evidence indicates that these designs are actually safer than conventional roadway designs. In analyzing crash data for several livable and comparable sections of roadway, livable sections had fewer fixed-object, multiple vehicle, and pedestrian crashes as well as fewer injuries and fatalities.
