Summary

Introduction. Road safety is one of the most pressing global challenges, particularly in Ukraine. Every year, millions of people worldwide are injured or lose their lives as a result of road traffic accidents (RTAs). These are not only personal tragedies for families but also a serious burden on healthcare systems, the economy, and the social sphere.

Problem statement. In the current conditions of Ukraine’s transport system development, ensuring road traffic safety is of particular importance. Each year, a significant number of RTAs occur on Ukrainian roads, the main causes of which are speeding and inappropriate choice of speed under specific traffic conditions. These factors are recognized as the primary contributors to both the frequency and severity of accidents. Excessive vehicle speed poses a critical problem, leading to fatalities, injuries, and material losses. The growing level of motorization, inadequate infrastructure, and insufficient enforcement of traffic regulations further exacerbate risks for all road users.

Purpose. To improve road traffic safety on Ukrainian roads and reduce accident rates by implementing a set of effective organizational and technical measures.

Materials and methods. The study applies statistical data processing to analyze accident rates on public roads. Current regulatory documents on traffic calming measures were also examined.

Results. The article analyzes the impact of speed on road safety and methods to reduce it, particularly in urban areas where the likelihood of pedestrian collisions is higher. A comprehensive approach to addressing road safety issues can significantly reduce accident rates, lower the number of fatalities and injuries, and create safer and more comfortable conditions for all road users.

Conclusions. Speeding is the most common cause of fatal RTAs in Ukraine. Speed not only affects the likelihood of an accident occurring but also the severity of its consequences. The relationship between speed and injury severity is especially critical for vulnerable road users such as pedestrians and cyclists. Therefore, it is necessary to apply traffic calming measures aimed at reducing speed, increasing driver attention, and ultimately lowering the probability of accidents.
