Spatio-Temporal Study of Road Traffic Crash on a National highway of Bangladesh

Abstract

Road traffic crashes (RTC) have now become a great social alarm in Bangladesh and the situation is deteriorating day by day. The road infrastructure of this nation is not standard and compatible with the rapid growth of urbanization and motorization. Which is why, the dimension of this problem is too challenging to solve. Though crashes do not show any regular pattern, but scientific research can reveal some common phenomenon like location, time, collision type and so on. The best option for a country to address the road crash is making the whole route safe by providing all required measures. But for a developing country like Bangladesh where investment comes on the basis of priority cannot manage all those standard. In this situation characteristic analysis and black spot identification would be a compromised way to ensure road safety. The methodology of this study incorporates a framework on the basis of spatial-temporal study to identify most RTC occurrence locations or hazardous road locations by using kernel density (KDE) tool of Arc GIS. In this study, an essential and economic corridor like Dhaka to Sylhet national expressway has been connected the technique. This examination suggests that KDE technique for distinguishing proof of Hazardous Road Location (HRL) could be utilized for all other national roadways in Bangladesh and furthermore for other creating nations. proposals have been recommended for policy maker to lessen RTC in Dhaka-Sylhet particularly in black spots.
