Issue Automated vehicles hold the potential to disrupt our transportation system in the 21st century. Experts predict that vehicles could be fully automated by as early as 2025 or as late as 2035. While vehicle automation may improving safety and efficiency and expanding mobility, the technology could also lead people to drive more often and […]
This report is intended to be a guide that provides helpful insights for researchers to use when navigating the process of Strategic Highway Research Program 2 (SHRP2) data acquisition and processing. Download PDF This report describes the methodologies and datasets used to prepare a set of data reductions that supported analyses of speeding behavior as […]
A systematic and ongoing method of measuring vehicle speeds was introduced in South Australia in 2007 in order to assess the effects of speed reduction countermeasures and to monitor the speed behavior of South Australian motorists over time. More than 100 sites around South Australia have speed measurements taken for a one week period at […]
This manual is the latest version of the FARS coding manual for the period 1982 to 2018, covering auxiliary datasets.
Safety is paramount in the work we do at the Alabama Department of Transportation. It begins with our pre-construction process, where we plan and design the safest roads and bridges possible. Whether it’s planning for new construction, replacing functionally obsolete or structurally deficient bridges, or widening shoulders scored with rumble strips on rural resurfacing projects, […]
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 […]
Traffic fatalities in 2018 declined 1.0 percent from 2017, to an estimated 36,750 people, according to preliminary data from the National Highway Traffic Safety Administration (NHTSA). As American motorists’ total vehicle miles traveled (VMT) increased by 0.4 percent in 2018, the fatality rate declined to an estimated 1.14 per 100 million VMT, a drop from […]
This report explores how seamless data collection, analysis and sharing can unlock innovations in transport safety. The rise of smartphones, sensors and connected objects is relentlessly producing more data. Progress in computing power, data science and artificial intelligence make it possible to interpret them. This presents an opportunity for the transport sector in general and […]
Roadway departure (RD) is recognized as one of the eight emphasis areas in the Virginia 2017-2021 Strategic Highway Safety Plan (SHSP), and the Virginia Department of Transportation (VDOT) currently uses counts of RD crashes to identify locations for RD safety improvement. However, identifying locations based on crash counts is subject to bias and inaccuracy, leading […]
In the year 2040, Alabamians will take stock of their transportation network and how it provides for economic growth and quality of life. They will look back on decisions made in 2019 by Alabama’s citizens, business community and Legislature. Exotic and disruptive innovations such as automated and autonomous vehicles, networked ridesharing, and cars and trucks […]
