Summary
This study addresses the lack of dedicated research on road traffic crash (RTC) injury severity for child vulnerable road users (VRUs) in the United Arab Emirates (UAE). While RTCs are a leading cause of child mortality in the UAE, previous studies have primarily focused on vehicle occupants. This research was motivated by the higher severity of injuries sustained by unprotected VRUs—defined here as pedestrians, bicyclists, and motorcyclists—and the UAE government’s promotion of active transportation policies to combat childhood obesity. The study aims to identify factors contributing to injury severity to inform safety policies and improve outcomes for child VRUs. The researchers analyzed eight years of RTC data (2012–2019) obtained from the UAE Ministry of Interior. From an initial dataset of 39,916 records, they filtered for injuries involving children aged 17 and under who were not vehicle occupants, resulting in a final sample of 1,437 child VRU injuries. Injury severity was classified into four levels: minor, moderate, severe, and fatal. The study employed descriptive statistics, Chi-squared tests, and multivariable ordinal logistic regression to assess the association between twenty independent variables—including demographic, temporal, environmental, and crash-related factors—and injury severity. Analyses were conducted for the general VRU population and separately for pedestrians, bicyclists, and motorcyclists. The results indicated that 90.3% of child VRUs were pedestrians, with boys comprising 74% of the sample. Significant factors associated with increased injury severity for the general VRU population included the emirate of occurrence (Sharjah, Abu Dhabi, and Ajman showed higher odds), younger age (infants/toddlers had higher odds than teenagers), crash site (dual carriageways), crash type (runovers), crash cause (drivers not considering other road users), posted speed limits, and road surface condition (dry surfaces had lower odds of severe injury compared to unpaved or wet surfaces). For child pedestrians specifically, residential locations and driver negligence/inattention were also significant predictors of severe injury. For child bicyclists, crashes occurring in car parks were significantly associated with greater injury severity. No significant factors were identified for child motorcyclists in the multivariable analysis, likely due to the small sample size. The study concludes that specific environmental and behavioral factors significantly influence the severity of injuries for child VRUs in the UAE. The findings highlight the vulnerability of younger children and pedestrians, particularly in residential areas and on dual carriageways. These results provide evidence-based recommendations for enhancing road safety infrastructure and policies, such as improving traffic safety zones around schools and residential areas, and addressing driver behavior. The study underscores the need for targeted interventions to protect child VRUs as the UAE promotes active transportation modes.
