Increasing evidence suggests that neighborhood-based measures of socioeconomic status are correlated with traffic injury. The main objective of this study is to determine the differences in associations between predictive variables and injury crashes (i.e. including injury and fatal crashes). To this end, crash data, socio-demographic, socioeconomic characteristics and road network variables ar...

There is a general belief that requesting driving assessments for older drivers without evidence of cognitive impairment is a poor use of resources. There is, however, limited empirical evidence to support this view. We prospectively followed 56 neurologically-healthy drivers aged 70–84 years for 24 months to determine whether a non-enforced pass or fail outcome on an on-road driving assessment...

Crash modification factors (CMFs) for road safety treatments are usually obtained through observational models based on reported crashes. Observational Bayesian before-and-after methods have been applied to obtain more precise estimates of CMFs by accounting for the regression-to-the-mean bias inherent in naive methods. However, sufficient crash data reported over an extended period of time are...

The significant role of pre-hospital emergency medical services (EMS) cannot be over emphasized as it encompasses minimizing the consequences of accidents and provides rapid response and relieve materials to victims of road traffic accidents at the scene of the crash. The paper therefore tries to analytically x-ray the relationship between income GDP per capital and the rate of road traffic dea...

Traffic crashes may not always result in severe or fatal injuries, but they can still have nontrivial impacts on system performance, particularly during heavy traffic conditions. One way toward reducing the frequency of such incidents is to first identify the necessary circumstances that resulted in the collision. However, road crashes, particularly intersection related crashes, are complex phe...

In October 2005, the United Nations General Assembly adopted a resolution to mark the third Sunday in November each year as World Day of Remembrance for Road Traffic Victims to honor persons killed or injured in road crashes, recognize their families and communities, and pay tribute to the emergency crews, police, and medical professionals who deal with the traumatic aftermath of road deaths an...

Numerous factors may contribute to high-severity crashes in highway work zones. Identifying these factors and then alleviating their impact is a challenging task that traffic engineers and researchers have to confront. In this study, the work zone risk factors that could increase the probability of causing fatalities when severe crashes occur were examined using a comprehensive approach. The re...

Microscopic computer models provide the opportunity to simulate vehicle and pedestrian behaviour under varying infrastructure conditions. Pre-crash and crash involvement risk at street, or even suburb level, can be explored and modified through various scenarios, such as: traffic calmed streets, pedestrian crossings, technology based infrastructure and other physical interventions. Models can s...

Motorcycle crashes constitute a significant proportion of traffic accidents all over the world. The aim of this paper was to examine the motorcycle crash patterns and rider fault status across the provinces of Iran. For this purpose, 6638 motorcycle crashes occurred in Iran through 2009-2012 were used as the analysis data and a two-step clustering approach was adopted as the analysis framework....

This study introduces the accident research system integrated with the medical and engineering network in Japan. Based on the collaborative study by Japan Automobile Research Institute (JARI), Nippon Medical School Chiba Hokuso Hospital and ITARDA (Institute for Traffic Accident Research and Data Analysis), detailed accident data have been collected, and crash, vehicle damage, and injury data w...
