Abstract
This paper investigates the issue of increasing motorcycle injuries and fatalities worldwide, with a focus on the United States state of California due to a lack of available data in the global south. The study provides a framework for other governments to investigate factors impacting motorcycle injury severity levels and develop policies to mitigate the impact of accidents. A multinomial logit models is used to analyze the effects of roadway type, rider characteristics, lighting conditions, and other attributes on injury levels of all motorcyclists involved in an accident in California between 2015-2020. The findings suggest that injury severity factors vary for single-vehicle and multi-vehicle accidents. Alcohol consumption, no helmet use, and interstates significantly contributed to injury severity for all categories of accidents. The study recommends policies to discourage alcohol use among motorcyclists, mandate helmet use, and improve roadway infrastructure. The research also suggests additional studies to understand better relationships between age groups, roadway types, and injury severity, as well as improved data consolidation and standardization to support more efficient analysis.
