Improved Methodology For Developing Non-Motorized Safety Perfomance Functions, Keneth Morgan Kwayu

Masters Theses

This study aimed at improving the methodology for developing statewide non-motorized safety performance functions (SPFs). Due to lack of pedestrian and bicyclist counts, the methodology proposed a procedure for developing statewide surrogate non-motorized exposure measures using data that are available at statewide level. Eleven years non-motorized crashes at signalized urban intersections joining Arterial and Collector roads in Michigan were used to test the procedure.

The study also explored the use of Bayesian approach for modeling non-motorized crashes as an alternative to traditional classical count data models. Classical count data models that were considered as potential fit to the data include; …

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 …
