| 摘要： | 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. |
