In 2019, the Uniform Law Commission (the “ULC”) finished drafting the Uniform Automated Operation of Vehicles Act (the “Act”), which proposes uniform state legislation that would regulate the operation of automated motor vehicles.1 This report summarizes the key sections of the Act, identifies areas of legislation not addressed, and reviews the current automated vehicle regulation […]
TUSCALOOSA, Ala. — The worst region for flash floods in the continental United States is likely the Southwest, according to a recent analysis of flash floods by The University of Alabama. Using hydrologic data, along with socio-economic information, researchers at the UA Center for Complex Hydrosystems, led by center director Dr. Hamid Moradkhani, mapped the hotspots for […]
This document contains examples of water buildup locations on mileposted and non-mileposted roadways. While these examples may be used by some statewide agencies (e.g., ALEA and ALDOT) to address potential problems that could either be fixed or mitigated by enforcement, they also have value in training of local agencies. This training should include instruction on […]
Wet Pavement Hot-spots are determined to help law enforcement officers know where crashes are more likely to occur during and shortly after wet weather. This will enable them to prevent crashes by law enforcement presence, which tends to slow the traffic and make the drivers more attentive. It will also be useful to positions law […]
The goal of this report is the improvement of traffic safety by mitigating young-driver (aged 16-20) risk-taking. We recognize that there is a wide range of problematic risky behaviors in addition to, or separate from, risk-taking while driving. A significant number of young people are identified and in need of direct help to address serious […]
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 current three-light system and electricity came in the […]
There are more fatal crashes during the days surrounding Independence Day than the rest of the year, according to an analysis of state traffic records by researchers at The University of Alabama. During the past five years, the five days around the Fourth of July averaged three fatal crashes a day, 29% higher than the […]
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 […]
