Room: Galleria
Abstract:

The purpose of this study was to critically examine how the rate and pattern of crashes in the Dhaka-Chittagong National Highway (NH-1) of Bangladesh changed after the highway was converted from an undivided two-lane highway to a four-lane highway divided by a median. The crash data of before and after this change was obtained from the Accident Research Institute (ARI) and the Bangladesh Police Department to conduct detailed analyses. The study found that head-on collision-related fatal crashes have been avoided. However, the overall rates of a few other vital types of crashes and crash-related injuries and fatalities, specifically crashes involving pedestrians, are rising. The study recommends some effective countermeasures to minimize highway crashes and their severities.

Learning Objectives:

Attendees can expect to learn the following from this session:
  • Upon completion, participant will be able to identify the need for road safety assessment of important highways.
  • Upon completion, participant will be able to conduct crash data analyses.
  • Upon completion, participant will be able to recommend highway traffic safety enhancement countermeasures.
