dc.description.abstractAccording to the World Health Organization’s 2015 global status report on road safety, nearly 1.25 million people are killed in road accidents each year, and millions more suffer serious injuries with long-term adverse health consequences. In Sri Lanka, road traffic fatalities have increased alarmingly from 3.0 to 10.8 deaths per million population per year, from 1938 to 2013.In this study, we carried out a micro-level analysis of accidents occurred on two major intercity highways (A001 and A004) in Sri Lanka. This study was mainly focused on analyzing crash-frequency and crash-injury severities on both highways A001 and A004. The traditional negative binomial (NB) regression model was used to predict the frequency of crashes of a specific severity level, as a function of explanatory variables and, multinomial logistic regression (MLR) was used to analyze the factors that prevailed in a specific crash leading to a certain crash severity, including site-specific factors on sections of both highways A001 and A004. Average daily traffic (ADT) and number of lanes were found as significant contributing factors in increasing the crash frequencies on both A001 and A004 highways. Urbanicity, weather and light condition, traffic control, casualty gender and age, protection, element type and collision type were the most vital ten crash injury severity contributors found on both A001 and A004 highways.en_US
