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.
