Bad assumptions make data from Weeks 1-14 insufficient. Please see accurate data from Week 15 forward. It is Week 8 of the coronavirus pandemic, and total crash data is still on the decline in Alabama. Crashes have declined to less than 40% of their pre-COVID levels, INCLUDING speed-involved and fatal crashes. View Graph This report comes […]

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 […]
