Effects of Highway Geometric Factors on Mountainous Roadway Crash Rate, Case Study: Lo Xo Pass, Ho Chi Minh Highway - Vietnam

Abstract

Road traffic accidents kill more than 1.2 million people worldwide each year. There are more than 8,000 deaths per year, an average of nearly one death related to road accidents per day in Vietnam. Due to terrain difficulties and limited construction costs, highway geometric factors do not meet the road safety standard and are always supposed to be the main factor contributing to crash on roads in mountainous areas This article presents some results of preliminary analysis on the effect of basic geometric factors on the crash rate on the Ho Chi Minh Highway, Lo Xo Pass segment, with crash data collected during 12 years of operation. The results presented in the article are useful reference for designers and road management department
