• Abstract:
  This report recommends performance measures for non-motorized (pedestrian and bicyclists) ; traffic safety for Michigan cities. Based on the data collected from four Michigan cities, Ann ; Arbor, East Lansing, Flint, and Grand Rapids, the research team analyzed non-motorized safety ; at three levels (city level, census tract level, and corridor level). The census tract-level analysis ; revealed that the number of access points, higher population with lower education, and higher ; exposure measures tended to increase non-motorized crashes. Through detailed corridor-level ; analyses, safety performance functions (SPF) for intersections and mid-blocks were developed. ; The intersection SPFs showed that higher average daily traffic (ADT), more number of bars, ; less number of lanes on minor approaches were associated with higher pedestrian crashes ; while intersections with right turn lane and bus stops exhibited relatively high number of bicycle ; crashes. Midblock SPFs also revealed that ADT, the number of access points, and the number ; of bus stops were factors leading to more non-motorized crashes. This research also presents ; results of before-and-after studies for non-motorized improvements and how performance ; measures are used when determining countermeasures.
