Blood samples from 2,500 injured drivers were analysed for alcohol, cannabinoids (measured by the presence of THC), benzodiazepines and stimulants. The relationship between the prevalence and concentration of drugs and the culpability of the driver was examined using an objective method for assessing culpability. There were no significant differences between males and females with respect to cu...

Navigation is the process of planning, recording, and controlling the movement of a craft or vehicle from one place to another. Navigating a vehicle in dynamic environment is one of the most demanding activities for drivers in daily life. American people drive 12,000 miles per year in average. Studies have long identified the difficulties that drivers have in planning and following efficient ro...

This analysis examines how the age of the vehicle at the time of the crash and the vehicle’s model year are correlated with the injury outcome of the driver of a passenger vehicle involved in a fatal crash. A multivariate logistic regression model was constructed to model the relationship between injury outcome (fatally injured versus survived) of the driver and the independent variables vehicl...

The recent decades have witnessed a fast rising number of motor vehicles. As a result traffic becomes more congested and streets become more risky. Temptations of widely varied communication and entertainment applications even make drivers more over-burdened and distracted. To relieve the continually increasing stress of drivers and reduce the number of accidents, current intelligent vehicle re...

OBJECTIVE To investigate differences in the incidence of motor vehicle crashes (MVCs) and violations among drivers with multiple sclerosis (MS) when cognitive impairment is present. DESIGN Archival evaluation of Department of Motor Vehicles (DMV) records. SETTING Medical rehabilitation research organization. PARTICIPANTS Community-dwelling drivers, 27 subjects with documented MS (14 MS wi...

OBJECTIVE Nationally, motor vehicle crashes are the leading cause of death among youth ages 16 to 20 years. Graduated driver licensing (GDL) laws have been implemented to reduce motor vehicle crashes among teen drivers. Studies have shown decreases in teen crash rates and crash-related fatality rates following enactment of GDL laws. However, GDL laws typically apply to teens only until their 18...

The population of older people continues to increase around the world, and this trend is expected to continue; the population of older drivers is increasing accordingly. January 2012 figures from the DVLA in the UK stated that there were more than 15 million drivers aged over 60; more than 1 million drivers were aged over 80. There is a need for specific research tools to understand and capture...

OBJECTIVES An experiment was conducted to assess the effects of distraction mitigation strategies on drivers' performance and productivity while engaged in an in-vehicle information system task. BACKGROUND Previous studies show that in-vehicle tasks undermine driver safety and there is a need to mitigate driver distraction. METHOD An advising strategy that alerts drivers to potential danger...

This paper presents the approach and methodology of the Large Truck Crash Causation Study (LTCCS), undertaken jointly by the Federal Motor Carrier Safety Administration and the National Highway Traffic Safety Administration. The LTCCS is a study of a nationally-representative sample of serious and fatal heavy truck crashes occurring between 2001 and 2003. The data collected provides a detailed ...

In this study we present onroad fossil fuel CO2 emissions estimated by the Vulcan Project, an effort quantifying fossil fuel CO2 emissions for the U.S. in high spatial and temporal resolution. This high-resolution data, aggregated at the state-level and classified in broad road and vehicle type categories, is compared to a commonly used national-average approach. We find that the use of nationa...
