The U.S. Department of Transportation (DOT) is leading a Safety Data Initiative (SDI), to enhance the analysis and visualization that informs safety policy decisions. In support of the SDI, Volpe applied machine learning techniques to assess the potential for crowd-sourced roadway data such as Waze alerts to serve as a reliable indicator of police-reportable crashes.

This research brief utilized data from the AAA Longitudinal Research on Aging Drivers (LongROAD) study to examine the amount and types of medications used by older drivers. Many medications – such as antihistamines, narcotic analgesics, central nervous system (CNS) drugs, muscle relaxants and tricyclic antidepressants – have been associated with increased crash risk. 1,2 We […]
Summary of Recommendations Speed Reduction Increase in patrol officers both at the ALEA and local levels Comprehensive demonstration speed reduction projects Legislative action to recognize problem and increase funding to ALEA specifically for field officers Continue hot-spot selective enforcement targeting and assure compliance to it Roadway improvements: trees, rollovers, utility poles, ditches, embankments Seat-belt (Restraint) […]
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 […]
The International Transport Forum collected mobility and road safety data from 31 cities, the majority of which in Europe, 10 in the Americas and 2 in Oceania. Indicators were developed to evaluate, monitor and benchmark road safety outcomes. A network of road safety experts was developed in parallel to support data collection and to exchange […]

In the previous five reports in this series, I examined recent changes in the number of registered light-duty vehicles (cars, SUVs, pickups, and vans), and the corresponding changes in distance driven and fuel consumed. The units of the analyses were both the absolute numbers and the rates per person, per driver, per household, and (where […]

The Fatal Crash Comparison (2016 vs 2014) study has been updated to include the new recommendations page at the top of the power point presentation.
The overall objectives of this study were to: Identify and explore alternative safety data sources and analysis perspectives Demonstrate the potential utility of these alternative approaches in increasing understanding of precipitating events and predisposing factors for crashes occurring on horizontal curves and at unsignalized intersections along rural two-lane roads.
