A multivariate analysis of crash and naturalistic driving data in relation to highway factors
This report documents the second phase of a two-phase project under the Transportation Research Board’s second Strategic Highway Research Program (SHRP 2) Safety Project S01C. A primary part of this work involved conducting a multivariate analysis of crash and naturalistic driving data in relation...
Assessment of the effectiveness of advanced collision avoidance technologies
This report describes the current state of knowledge regarding the effectiveness of several advanced collision-avoidance technologies (ACATs) and presents an assessment of the effect of each technology on traffic safety. The report covers only ACATs for light-duty vehicles. The literature reviewed...
Road safety in 170 low-, middle-, and high-income countries
Earlier this year, the World Health Organization published a comprehensive assessment of road safety in the individual countries of the world (WHO, 2013). The present study used the WHO data for individual countries but focused on differences based on the level of development. The goal was to...
A comparison of CAFE standards and actual CAFE performance of new light-duty vehicles
In August 2012, the U.S. Environmental Protection Agency (EPA) and the National Highway Traffic Safety Administration (NHTSA) announced the final standard governing new-vehicle fuel economy for model years 2017 through 2025. The new standard maintains the current system of incremental increases in...
Reverse innovation for the new mobility
The confluence of increasing urbanization with climate change, and the associated need to decarbonize the economy, is driving urgency for the global adoption and diffusion of sustainable scalable solutions. IT-enabled, multi-modal transportation, often referred to as the “new mobility�, is...
Tire operational and sustainability tradeoffs
This report forecasts likely changes in passenger car and light truck fuel economy through 2025 as a result of projected tire evolution with respect to aspect ratio and design inflation pressure. Tire-material evolution over the last decade is expected to continue. Tire aspect ratios from 55 to 85...
A survey of driver opinion about carbon capture in vehicles
An online survey of driver opinion was conducted to determine how receptive drivers would be to in-vehicle technologies that reduce carbon emissions. In particular, the survey was designed to help understand whether drivers considered such technology attractive and, if so, what level of cost would...
Trucks involved in fatal accidents codebook 2010
This report provides documentation for UMTRI’s file of Trucks Involved in Fatal Accidents (TIFA), 2010, including distributions of the code values for each variable in the file. The 2010 TIFA file is a census of all medium and heavy trucks involved in a fatal accident in the United States. The...
The seated soldier study : posture and body shape in vehicle seats
Designing vehicles for the safety and comfort of occupants requires detailed information on posture, position, and body shape . This report presents the methods and results of a study of soldiers as drivers and passengers in vehicle seats. A total of 257 ma le and 53 female soldiers were measured...
Anthropometric Evaluation of THOR-05F
An exemplar THOR 05F was compared to the anthropometric specification from the Anthropometry of Motor Vehicle Occupants (AMVO) study on a wide variety of dimensions, including segment lengths, masses and CG locations; relative joint and landmark positions; and external body contours. Overall, the...
