Abstract

Road bumps are elevated pavements placed transversely to the road, forcing the driver to reduce the speed of their vehicles. They play a crucial role in increasing safety at sharp curves, residential streets and accident prone areas by controlling the speed of the vehicles. The amount of speed reduced mainly depends on length, height, and type of speed breakers. Major types of speed breakers generally adopted are speed bumps, speed humps, and artificial speed breakers. This paper aims to find the variation of speeds of different class of vehicles at speed breakers and to develop a model for finding the bump height that should be provided at that particular road for a given safe speed limits of different types of vehicles on that road section. To achieve this, three locations were selected, two locations in Hyderabad and one location near Autonagar area of Vijayawada city. Volume counts for the above roads were observed for every 15 -minute intervals. The video was recorded during peak hours and the variation of speeds before and after 10 m from speed breakers were calculated at these locations. The average reduction in speed of vehicles with respect to the approaching speed at the distance of 10 m from bump is 52.69% at KPHB, 64.5% at ORR, and 39.26% at Vijayawada.
