Accident Hotspot Identification using Geometric Problems and Characteristics in Selected Road of the Dhaka-Aricha Highway (N5)
Abstract
The Dhaka-Aricha highway is an important link for west-south interregional road network in Bangladesh. According to police accident records (each year about 75 km road segment, 180 accidents and 120 fatalities occurs) it is also the most dangerous in terms of per kilometer accidents and fatalities. Total 25000 number of vehicles of all types including motorized and non-motorized run through this highway every day. Road accident is a regular phenomenon of this highway. The data for this study have been collected from field survey, local police stations, Roads and Highway Department, Road Safety Department, Accident Research Institute, BUET and by using MAAP software. The results of the 150 samples reveal that 38 percent of the fatalities were between the ages of 20 and 35. Buses (83.33 %) and trucks are the most common vehicles involved in accidents (62%). At 6am to 12pm is the most accident accruing time. The other result shows pressure of vehicles, geometric characteristics, overtaking in speed by competing drivers, are the major causes of road accidents in this highway. The most vulnerable points of road accident are Dhamria town, Golara, Joypura, Kalampur, Bathuli, Mulzan, Tepra Bus stand, Paturia intersection of the district. To reduce the rate of accidents in this highway some geometric measures and awareness building among the road users should be bring together to reduce accident.
