초록
High fatality rate in road accident of Bangladesh warrants immediate repair of the faulty roads. But due to limited amount of resources, it requires a prioritization of road improvement functions. One of the important factors for road maintenance prioritization is road safety. Road fatality risk is lavishly used for measuring road safety. Most deserving tool for measuring fatality risk exposure – “fatalities per million kilometers traveled” requires information over road fatality and vehicles per hour in every specific links of national roads. The Road Maintenance Management System (RMMS) of Roads and Highway Department (RHD) of Bangladesh provide vehicle per hour information based on road links that belongs to multiple administrative segments of Bangladesh. On the other hand, Bangladesh Roads Transport Authority (BRTA) provides information over road fatalities corresponding to administrative segments. This creates problem in priority score calculation and allocating limited funds among many administrative segments so that the reduction of road fatalities can be achieved in best possible way. However recent adaption of geographic information system (GIS) for administrative and road information allows revealing road length data and thus approximating the information required for measuring fatality risk exposure. This research explains a methodology to identify a verified fatality index for prioritizing national road maintenance and also ranks the districts of Bangladesh using such methodology. The Ministry of Communication and Transportation, RHD and the respective district administration can use this methodology for scheduling the required maintenance of national main roads and thereby can reduce road accident fatalities in Bangladesh.
Abstract
