The percentage of passenger vehicle drivers talking on handheld phones decreased from 2.5 percent in 2021 to 2.1 percent in 2022 (Figure 1 and Table 1). The percentage of drivers speaking with visible headsets while driving remained unchanged from the previous year’s level of 0.4 percent (Figure 1 and Table 2). Drivers’ visible manipulation of […]
A new report from the Governors Highway Safety Association (GHSA), with the support of State Farm®, examines traffic safety cameras – an underutilized tool in the fight to reduce dangerous driving behaviors that contribute to more than 100 people dying on U.S. roads every day. The report discusses the benefits of traffic safety cameras that […]
Automated vehicles have the potential to improve safety and mobility. At lower levels of automation (Level 2), drivers are required to supervise the automation and be prepared to intervene as needed to maintain safety. The consequences of these technologies on driver behavior are not yet fully understood, especially as real-world testing has been less common […]
This project started with a broad question: What can new, rich naturalistic driver data such as in the Second Strategic Highway Research Program’s Naturalistic Driving Study (SHRP2-NDS), tell us about how drivers react to roadway designs and access management techniques? To address this question, the project team reviewed and analyzed 6,209 trips that drivers in […]
MONTGOMERY — The Alabama Law Enforcement Agency (ALEA) and the Alabama Department of Transportation (ALDOT) are launching a campaign to promote safety along Alabama interstate highways. Roughly 13 percent of roadway fatalities occurred within Alabama in 2020 along interstate highways. As part of the campaign, additional ALEA Troopers will be assigned to specific locations along […]
Traffic safety professionals are tasked with the complexities of finding ways to change behavior. Significant progress has been made in addressing several risky behaviors like not wearing a seat belt and driving aggressively resulting in fewer people engaging in these behaviors. However, a small portion of the population (i.e., about 10 percent) still does not […]
With the increased use of electronic devices, distracted driving is assumed to be one of the main causes of crashes. The Illinois Department of Transportation (IDOT) has demonstrated interest in addressing distracted driving. However, the real impact of distracted driving on traffic crashes in Illinois is still unclear because of what appears to be a […]
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 […]
