Speed of vehicles is one of the major reasons for road crashes. Implementations of traffic calming measures can reduce these kinds of crashes up to an extent. In this study we try to analyse the effects of installing tubular marker on an accident-prone study stretch. The stretch selected is a curve with overtaking behaviour leading to crashes. The pre- and post-conditions prevailing relating to vehicle speed and accident data have been taken into account for the analysis. The Infra-Red Traffic Logger (TIRTL) has been used to determine the vehicle speed and count. A sharp reduction in the average speed was observed—in case of the vehicles like Light Motor Vehicle (LMV), Medium Commercial Vehicle (MCV) and Multi Axle Vehicle (MAV)—after installing tubular marker. There was a decline in the accident rate also since over-taking was restricted. Speed reduction was found to be more effective on larger vehicles since that class would be more affected by the overtaking hindrance in-stalled. No statistical significance in mean speeds was observed for smaller vehicles like two-wheeler and three-wheeler due to their better maneuverability.
