This paper presents a comprehensive literature review on road traffic accident prediction
models (APMs) and crash modification factors (CMFs). The focus is on motorways and …

This study presents an empirical investigation of the impacts of real-time weather conditions
on the freeway crash severity. A Bayesian spatial generalized ordered logit model was …

This study attempts to examine the main and interaction effects of roadway and weather
conditions on crash incidence, using the comprehensive crash, traffic and weather data from …

Road transportation is more favoured as it is less expensive and relatively faster than other
modes of transportation. A higher probability of getting involved in crashes reveals its …

Recent studies have begun to shed more light on the crashes experienced on rural roads by
examining the influence of a road's pavement surface condition. In a bid to contribute to this …

Improving road safety through proper pavement maintenance is one of the goals of
pavement management. Many studies have found that pavement conditions significantly …

This paper examined the accident risk factors associated with highway traffic and roadway
design, for each of three highway classes in the United States using a bivariate modeling …

The objective of this study is to quantify the safety performance of horizontal curves on two-
way, two-lane rural roads relative to tangent segments. Past research is limited by small …

The geometric design of the combinations of horizontal and sag vertical curves (sag
combinations or sag combined curves) is vital to road safety. However, there is little research …

Highway agencies continue to show interest in measuring pavement condition effects on
safety. This paper estimates univariate negative binomial (UNB) and random-parameters …
