Projects

 

Traffic Injury Research Foundation’s mission to reduce the road crash problem is accomplished by undertaking nearly two dozen research projects each year. With the opening of TIRF USA, we can now expand the breadth of expertise and outreach, sharing the knowledge that saves.

Below you may find some of the projects that are currently in progress or recently completed in partnership with Traffic Injury Research Foundation Canada.

TIRF USA Annual Ignition Interlock Survey: United States

The Traffic Injury Research Foundation USA, Inc. (TIRF USA) in partnership with the Association of Ignition Interlock Program Administrators (AIIPA) and TIRF in Canada conducted a national survey of the number of total installed and active installed ignition interlocks in the United States in 2016 and 2017. These data provide a comprehensive picture of interlock installations across the United States and are a useful benchmark for state ignition interlock program administrators and the impaired driving community to measure interlock program participation. Trends based on comparisons with data from 2014, 2015 and 2016 are described.

New TIRF USA, Inc. Project: Educational resource for effective communication about the impairing risks of prescribed pain medication while driving

The Traffic Injury Research Foundation USA, Inc. (TIRF USA), in partnership with TIRF in Canada, is pleased to announce they have received funding from the US Food and Drug Administration (FDA) to develop and evaluate an educational resource. The purpose of the resource is to develop more effective communication tools to help prescribing health care professionals (HCPs) talk to patients about the impairing effects of prescribed pain medication and the risks associated with driving. The TIRF organizations have also partnered with Washington University School of Medicine in St. Louis to inform the development of this important resource that will benefit HCPs and the public alike. The research team will use TIRF’s established Knowledge Translation (KT) model to collect and synthesize focus group information and results will be used to inform the development of the resource. It will also be evaluated based on a comparison of HCPs and patients who are using the resource versus a control group of HCPs and patients who are not using it.

The anticipated completion date for the project is September 2018.

TIRF USA, Inc. Project: National Opinion Polls on Alcohol-Impaired Driving in the United States

The Traffic Injury Research Foundation USA, Inc. (TIRF USA), in partnership with TIRF in Canada and with sponsorship from the Anheuser-Busch Foundation, released the fifth annual Road Safety Monitor (RSM) on alcohol-impaired driving. This fact sheet provides a general overview of key results related to the prevalence of alcohol-impaired driving, reasons for engaging in this behavior and characteristics of drivers, as well as concern about this and other road safety topics. The number of alcohol-impaired driving fatalities continues to decrease for the second time in a row, which is indicative of progress achieved. According to crash data from the National Highway Traffic Safety Administration, the number decreased from 10,996 deaths in 2016 to 10,908 in 2017 and 10,511 in 2018, meaning hundreds of lives were saved in the past two years. Other positive trends include the increase in the number of drivers stating they relied on safe rides as an alternative strategy to avoid alcohol-impaired driving.

The number of drivers indicating they had been a designated driver, used a designated driver, used a taxi or public transportation or ridesharing rose from 177 million drivers in 2017 to 187 million in 2019. Results of this RSM also show that the percent of respondents who reported driving when they thought they were over the legal limit in the last 12 months significantly increased from 11.6% in 2018 to 20% in 2019. This is the highest prevalence reported during the past five years of data collection. While more data are needed to monitor trends, the significant increase in self-reported alcohol-impaired driving is a concern. It is an early warning that the number of alcohol-impaired driving fatalities in 2019 may increase without continued and increased efforts.

Regarding marijuana use and driving, public awareness is often characterized by misperceptions about its impairing effects. RSM results found that 58% of respondents perceive marijuana/THC-impaired drivers to be a serious problem. Furthermore, 53% perceive driving after consuming or vaping CBD/cannabidiol to be a serious problem, even though its impact on crash risk is not fully understood with the available evidence. Misperceptions and misunderstandings about the impairing effects of marijuana on driving can have a direct impact on the rates of marijuana-impaired driving and marijuana-impaired crashes. More research is needed to better understand the complexities of the science, as well as targeted educational strategies and increased awareness campaigns about the effects of both alcohol and marijuana impairment.
