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; …

Standardizing Functional Safety Assessments For Off-The-Shelf Instrumentation And Controls, Andrew Michael Nack
Masters Theses
It is typical for digital instrumentation and controls, used to manage significant risk, to undergo substantial amounts of scrutiny. The equipment must be proven to have the necessary level of design integrity. The details of the scrutiny vary based on the particular industry, but the ultimate goal is to provide sufficient evidence that the equipment will operate successfully when performing their required functions.
To be able to stand up to the scrutiny and more importantly, successfully perform the required safety functions, the equipment must be designed to defend against random hardware failures and also to prevent systematic faults. These design …

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 …
