Analysis Of Pedestrian And Bicycle Crashes In Michigan, Ahmed Abbas Ghubin Al-Zubaidi
Masters Theses
Vulnerable road users such as pedestrian and bicyclists are more likely to sustain a severe injury when they are involved in a crash with motor vehicles. Identifying the causes of crashes involving pedestrians and bicyclists is essential to reducing the number and the severity of such crashes. This study identified the causes and risk behaviors associated with pedestrian and bicycle crashes in Michigan by reviewing selected individual crash report (i.e., UD-10). Crash reports for all pedestrian and bicycle fatal crashes (K) and a sample of incapacitating injury crashes (A) from 2010 to 2014 were reviewed and typed individually using the …
Development Of Safety Performance Functions For Non-Motorized Traffic Safety, Hamidreza Ahady Dolatsara
Development Of Safety Performance Functions For Non-Motorized Traffic Safety, Hamidreza Ahady Dolatsara
Masters Theses
This study investigates the factors which affect the safety of non-motorized transportation within the influence area of intersections to enhance development of safety performance functions (SPFs). The scope of this study is limited to the four Michigan cities of Ann Arbor, East Lansing, Flint and Grand Rapids. Due to the current lack of research regarding the appropriate size of the influence area, this study investigates the distance of crashes relative to the center of 148 intersections to identify the most probable area of influence for different crash types. For motorized and non-motorized crashes, 240 ft. and 137 ft. are proposed, …
Spatial Factors Impacting Non-Motorized Exposures And Crash Risks, Farhad Abasahl
Spatial Factors Impacting Non-Motorized Exposures And Crash Risks, Farhad Abasahl
Masters Theses
This research investigates spatial factors, that impact non-motorized exposures and crashes, and examines the relationship between exposure at signalized intersections and crash frequencies involving pedestrians and bicycles at a census tract level. The four Michigan cities of Ann Arbor, East Lansing, Flint and Grand Rapids are examined. After completing an extensive literature review to provide a list of required data, 92 intersections are selected from the four cities to collect pedestrian and bicyclist counts. Five-year crash records, special attractions, non-motorized facilities and transportation infrastructure data for the four cities are gathered for the four cities. This data are later mapped …
