This thesis investigates the effect of headlight glare on driving Case on BahirDar to Gondar Road in Ethiopia. The study aims to examine the frequency and severity of headlight glare experienced by drivers, identify its impact on driving behavior and collisions, and explore potential solutions to address this safety issue. Data was collected through a survey of 385 drivers, capturing information on their experiences with headlight glare, the effects of glare on driving, causes of collisions, and training in low-light driving and headlight adjustment. The findings reveal that a majority of drivers (60%) experienced headlight glare, with temporary blindness being the most common effect. Headlight glare was reported as a significant contributor to collisions by 40% of participants. Moreover, most drivers (69.6%) had not received any formal training on low-light driving or headlight adjustment. The study highlights the need to reduce headlight glare on the BahirDar to Gondar Road and suggests potential solutions such as better road lighting, driver education, and enforcement of headlight regulations. The analysis of relationships between variables and demographic factors provides insights into the effectiveness of different strategies to reduce headlight glare and improve driving safety. The study also conducts field data analysis, examining the impact of headlight glare on driving performance by considering factors such as illumination levels, discomfort glare, and discomfort glare rating among different vehicle types. The results underscore the variability of discomfort glare levels influenced by factors such as vehicle type, distance, and angle. These findings contribute to the existing knowledge on road safety and provide a basis for developing targeted interventions to mitigate headlight glare effects. The study concludes by discussing the implications for driving safety, suggesting potential solutions, highlighting limitations, and recommending further research to address the gaps in knowledge.
