The development of road databases and analysis of traffic accident-prone section (blacksite) based on Geographic Information System (GIS)

Abstract

Historical data on traffic accidents can provide information on blacksite areas. This can aid in the approach for reducing the number of traffic accidents. Therefore, this research aims to develop database of traffic accidents by the implementation of Quantum Geographic Information System (QGIS) and its interface uses ArcView GIS. We found that there are 69 roads which are identified as the location of traffic accidents. Of these, there are 15 roads as blacksite. The most vulnerable road is the Timor Raya road which has an accident rate (APW) of 813.2 and a UCL value of 71.55. This database provides comprehensive information on geometric conditions of the road, accident data and blacksite, and also features road photographs and cross-sectional road drawings.
