Truck-involved crashes have higher crash severity than non-truck-involved crashes. There have been many studies about the frequency of crashes and the development of severity models, but those studies only analyzed the relationship between observed variables. To identify why more people are injured or killed when trucks are involved in the crash, we must examine to quantify the complex causal r...

Injury due to road traffic crash is a major cause of ill health and premature deaths in developing countries. Taxis provide a main mode of public transport in Vietnam but there has been little research on the risk of crash for taxi drivers. This retrospective study collected information on taxi crashes for the period 2006-2009 by interviewing drivers from five taxi companies in Hanoi, Vietnam, ...

Article history: Received 14 May 2013 Received in revised form 21 January 2015 Accepted 22 January 2015 Available online 30 January 2015 This paper examines the effect of a firm's crash-risk exposure on its speed of leverage adjustment (SOA), and how this effect is influenced by the information environment of the country in which the firm is located.We employ a panel of 19,247 firms across 41 c...

In the absence of suitable crash data, speed observation data can give an indication of the effectiveness of speed-related road safety countermeasures. It is proposed that the use of risk-weighted data is more appropriate. The aim of this investigation was to develop a method for risk-weighting speed observation data in both urban and rural areas for use as an evaluation tool. Speed observation...

This study estimates the dose-response relationship between body mass index (BMI) and crash risk in operators of heavy commercial motor vehicles. Intake data were collected during the first two weeks of instruction from 744 new truck drivers training for their commercial driver's licenses at a school operated by the cooperating trucking firm. Drivers were then followed prospectively on the job ...

OBJECTIVE Signalized intersections are accident-prone areas especially for rear-end crashes due to the fact that the diversity of the braking behaviors of drivers increases during the signal change. The objective of this article is to improve knowledge of the relationship between rear-end crashes occurring at signalized intersections and a series of potential traffic risk factors classified by ...

PURPOSE Faced with an aging driving population, interest is increasing in the use of restricted licenses or "graduated delicensing" for older drivers to allow them to safely retain a driver's license. The primary purpose of this study was to determine whether restricted licenses are successful at mitigating number of crashes per year and whether they can extend the period of crash-free driving ...

Novice teen drivers have disproportionally elevated crash rate compared to older drivers’. The high crash rate among novices is generally attributed to multiple risk factors, including driving inexperience, young age, risky driving behavior, vehicle accessibility, time of day, and driving with teenage passengers. The current naturalistic driving study with novice-teenagers evaluated the associa...
