Abstract

Transportation plays a critical role in the economic sector in Bangladesh. Since its independence, infrastructure has been developing rapidly, including land, water, and air transportation. National economy is increasing at a relatively high rate, leading to the better-off of people’s lives. As the living standards keep improving, people are more concerned about safety issues in transportation. This article makes an analysis of the status quo of traffic safety in Bangladesh and compares the Bangladeshi code with American code AASHTO from the geometric aspects of horizontal and vertical alignment, in an eff ort to provide reference to the highway design in Bangladesh. Through a reasonable design, the traffi c safety will be under control and accident rate as well as economic loss will be minimized.
