Vehicular Speed Behaviour Along Road Construction Corridors
The road construction and maintenance activities are an integral part of road life cycle. The accident rate is more in construction corridors. Lower speeds are necessary along construction corridors considering safety of road users and construction crew. This study is conducted to investigate the actual vehicular speeds maintained along the construction corridors on national highways, as compared to the standards. Also, an attempt is made to quantify the effectiveness of road safety adopted on heterogeneous traffic speed behaviour along the construction corridors. Speed studies are carried out along ten construction corridors, identified enroute where upgradation of existing 4 lane divided carriageway to six-lane national highway, connecting Bengaluru to Mysuru, in the state of Karnataka, India. The geometrics onsite have been compared with the standard requirements. The rate of speed reduction through the advance warning zones towards the work zone for the vehicular traffic was found to be around 23%. The rate of increase in the speed was observed to be around 18% for the vehicles exiting the work zone. The studies concluded that the heterogenous traffic exceeded the permissible speed limit by 75–88% along the construction corridors. However, the rate of speed reduction and increase was found to vary for different vehicle categories. This study forms a window to understand the traffic behaviour along the construction corridors in similar geographical areas.
