Thesis Details    

Road safety at intersections is a critical aspect of urban traffic management, as intersections are among the most complex and high-risk elements of the roadway network. They serve as convergence points for multiple traffic streams—vehicles, cyclists, and pedestrians—moving in different directions, often leading to conflicts and potential crashes. The safety performance of an intersection depends on several factors, including its geometric design, traffic control systems, visibility, land use patterns, and driver as well as pedestrian behavior. Poorly designed intersections, inadequate signage, lack of pedestrian infrastructure, and violations of traffic rules are major contributors to intersection-related accidents, which frequently result in severe injuries or fatalities.

In developing countries like India, the problem is more pronounced due to rapid urbanization, mixed traffic conditions, and insufficient enforcement of safety measures. Intersections in urban areas often experience congestion, risky maneuvers such as red-light jumping, and unsafe pedestrian crossings, further increasing the likelihood of crashes. Research has shown that a significant proportion of road traffic accidents occur at or near intersections, emphasizing the urgent need for systematic safety evaluations and improvement strategies.Enhancing road safety at intersections requires a multidisciplinary approach involving engineering, enforcement, education, and emergency response. Implementing context-sensitive designs—such as roundabouts, signalized intersections with appropriate cycle timing, raised pedestrian crossings, and channelization—can significantly reduce conflict points and improve traffic flow. Moreover, integrating smart technologies like adaptive traffic signals, red-light cameras, and real-time data analytics can enhance compliance and reduce human error.Ultimately, ensuring safety at intersections is not just a matter of infrastructure improvement but also of behavioral change and policy commitment. A holistic approach combining design innovation, data-driven assessment, and public awareness can lead to safer, more efficient, and sustainable urban mobility systems.
