This document currently contains the results of a study of young drivers (5-15) of All Terrain Vehicles (ATVs), Bicycles (Bic) and Motorcycles (Mot). It was part of a more comprehensive study of young victims of motor vehicle crashes that resulted in three closely related analyses of passengers and drivers in motor vehicle crashes with the […]
This PowerPoint presents a model of data integration of geo-located weather and roadway data for decision making with the US Department of Transportation, the National Weather Service, and end- users who need integrated data for better roadway weather decision making. The application of this Roadway Weather Data Implementation (RWDI) in Alabama and Georgia serves as […]
Green. Yellow. Red. Go. Slow. Stop. Simple instructions commanded by a seemingly simple machine – the traffic light. The technology is as old as the Industrial Revolution, with the first light, two gas-powered flames, controlling traffic in London in 1868. They have improved since, of course.

The purpose of this report is to update the quantitative relationships between wet weather (and resulting wet pavement) on crash frequency and severity that were original reported in a Power Point presentation in 2014. The objective of this second update is to determine the degree to which the dramatic increase in fatal crashes in CY2016 […]

This document reports the results of a study to determine on average over a large number of cases, which driver is more apt to be at fault in two-vehicle crashes that involve two types of drivers (e.g., large truck and car; car and pedestrian, car and bicycle, car and motorcycle, etc.). This information is essential […]
This document presents the results of a comparison of ID crashes compared to non-ID crashes over a recent three year period (FY2015-2017). An over-represented value of an attribute is a situation found where that attribute has a greater share of ID crashes than would be expected if it were the same as that same attribute […]
