Development of Strategies to Enhance the Safety at Roundabouts

The amount of road accidents and fatalities at intersection in worldwide is alarming. A large number of traffic accidents take place at intersections on urban roads in India. These statistical data indicate that intersections are the place of serious safety concern. Roundabout is a type of intersection which is designated for safe and smooth channelization and movements of vehicles in desired direction through a central island. Weaving, Crossing, merging, diverging are some process, which leads to complex movement conditions at roundabouts especially on mix traffic condition in Indian roads. It may be said that roundabout intersections are among the most hazardous locations on Indian roadway system. Hence, objective of this study is to develop some strategies that can be useful to enhance the safety at roundabout. There are a total number of fifteen factors which effects the roundabout safety and among them we present the major three of them in our study. The proposed strategies are illustrated with the help of three roundabouts of the capital city of Bhopal. It may be concluded from the study that the strategies proposed are useful to enhance safety at roundabout. Thus, it is expected that this analysis may be useful for enhancing safety on urban roads in India.
