- Overcome Senior Driver Concerns With Occupational Therapy
The newly launched older driver video, made possible by the National Highway Traffic Safety Administration (NHTSA), provides a look into the ways occupational therapy can assist in senior drivers retaining their independence and mobility. An occupational therapy practitioner focuses on Instrumental Activities of Daily Living (IADLs), which are activities that permit individuals to live independently and contribute to overall quality of life. For older drivers, age-related illnesses, chronic conditions, and sudden changes in health, such as a stroke or a heart attack, can impair driving ability. Changes to an older driver’s health do not automatically mean giving up independence or, in this case, the keys to the car. An occupational therapist can aid older drivers in maintaining their mobility through consultation, evaluation, and recommendations to their driving experience. Watch the video to learn more about how occupational therapy practitioners can help seniors drive toward independence. Speak to your primary care physician about community mobility and partnering with occupational therapy.

Parents and caregivers can help their child by encouraging safe behaviors while walking. This resource provides tips for pedestrian safety for any walking trip, with some special considerations for the trip to and from the school bus.
- Education on Proper Use of Seat Belts on School Buses (PDF, 857 KB) January 2021; DOT HS 812 999
NHTSA sponsored a project to understand how school districts that purchase large school buses with seat belts can maximize their effectiveness and benefit by improving proper usage. The project obtained observational data related to the impact of seat belts on student behavior on buses and on bus driver distraction. This report synthesizes anecdotal data collected from school districts across the United States. Through interviews, surveys, and material collected, the project team examined the common components of the seat belt use policies, such as how policies were carried out by school bus drivers, and consequences for non-compliance, to better understand the factors that can influence seat belt use. In general, the most important factors in successful planning seem to be training, education, and enforcement. Most interview and survey respondents said they observed that seat belts on school buses contributed to calmer and less distracted environments for school bus drivers. While the opinions about seat belts often varied from driver to driver, the project team heard from drivers and supervisors that those drivers who invested more time and effort into seat belts (e.g., by maintaining and enforcing a consistent seat belt use policy) derived the most benefit.
The National Highway Traffic Safety Administration is engaged in numerous activities to reduce drug-impaired driving, including conducting research and developing tools, resources, and promising practices to assist states and local communities. To aid in evaluating efforts to address drug-impaired driving, NHTSA has developed the Drug-Impaired Driving Criminal Justice Evaluation Tool. The tool is designed to assist with identifying program strengths and opportunities for improvements. After asking two organizations to test the model to explore weaknesses and identify areas for refinement, NHTSA now wishes to learn from other practitioners what improvements and refinements could add value to the tool.

- May is Motorcycle Safety Awareness Month and National Ride to Work Day is June 21, 2021
According to NHTSA, in 2017 there were 5,172 motorcyclists killed in motor vehicle traffic crashes – a decrease of 3 percent from the 5,337 motorcyclists killed in 2016. Of the 5,172 motorcyclists killed in traffic crashes, 94 percent (4,885) were riders and 6 percent (287) were passengers. Motorcyclists are significantly overrepresented in traffic crashes and fatalities. In 2017, motorcycles made up 3 percent of all registered vehicles in the United States and accounted for only 0.6 percent of all vehicle miles traveled. Per registered vehicle, the fatality rate for motorcyclists in 2017 was 6 times the fatality rate for passenger car occupants. Even the smallest momentary lapse in a vehicle driver’s awareness can result in the death of an unseen motorcyclist.

Examination of the Traffic Safety Environment During the Second Quarter of 2020: Special Report (PDF, 1 MB) October 2020; DOT HS 813 011
The National Highway Traffic Safety Administration is reviewing national changes in roadway travel and changes in drivers’ behavior that have occurred since the start of the COVID-19 public health emergency, with an emphasis on the second quarter (Q2) of 2020. Most important, we are learning about the impact on motor vehicle crashes and fatalities. This report draws from an array of sources to bring together as much information as possible to provide an understanding of our current traffic safety environment, and to better address our changing traffic safety needs. Prior economic downturns, such as the financial crisis of 2008, provide some comparison for reduced roadway travel and changes in travel patterns. As this report documents, although there are some similarities with that time frame, there are many differences in impact on speeding and other dangerous driving behaviors, such as reduced seat belt use. This report explores changes in countermeasure use including traffic enforcement and public communications and outreach. This report also examines the question of whether some people – who continued driving even when many communities had stay-at-home guidelines – may be inherently higher-risk drivers. The report draws on sources such as emergency medical services (EMS) and hospital trauma center data as we examine this issue.
Child Passenger Safety
- Awareness and Availability of Child Passenger Safety Information Resources (PDF, 3.45 MB) December 2020; DOT HS 813 035
Child restraint systems (CRSs) are an effective method to reduce the risk of child injury in motor vehicle crashes. Research indicates that hands-on instruction demonstrating the installation and use of CRSs is effective in reducing misuse of CRSs. Child passenger safety technicians (CPSTs) currently provide one-on-one instruction on the proper use and installation of CRSs at thousands of child car seat inspection stations nationwide. The primary objective of the Awareness and Availability of Child Passenger Safety Information Resources (AACPSIR) survey was to estimate the degree of awareness parents and caregivers have of CPST inspection stations. The researchers recruited a nationally representative sample of caregivers who drove children regularly. Key data analysis methods included descriptive analyses, cross-tabulation analyses, weighted linear regression or logistic regression analyses, and causality analysis to determine the effects of distance on the use of child car seat inspection stations. In addition, exploratory linked analysis to the National Survey of the Use of Booster Seats (NSUBS) data was conducted to examine the relationships among selected AACPSIR outcome variables and selected explanatory variables from the AACPSIR and NSUBS data. The study found that two-thirds of adults who drove children on a regular basis had heard of inspection stations (67%). Drivers who transport children frequently indicated they were confident their CRSs were installed correctly. However, the AACPSIR survey found that 19 percent of children were not riding in the correct CRS for their height and weight. There were higher rates of improper selection in the 2- to 3-year-old and the 8- to 9-year-old age groups than among other ages.
- Evaluation of Correct Child Restraint System Installation (PDF, 2.8 MB) July 2020; DOT HS 812 976
This research project used an experimental design, called an “incomplete factorial” type, with a convenience sample of 75 novice and 75 experienced child restraint system (CRS) users to test whether user experience, child’s age/weight/height, vehicle characteristics, and CRS characteristics are associated with installation errors. This study identified conditions related to correct and incorrect CRS use to inform programming and education with the goal of increasing correct use. The results help frame the target population for programming and education as not only novice users, but also experienced users, as the study did not find a significant difference in errors by experience.
- A Guide to Implementing Child Passenger Safety Inspection Stations (PDF, 378 KB) March 2021; DOT HS 812 692
This guide provides recommendations for implementing child passenger safety inspection stations. Inspection stations are an effective way to increase the proper use of car seats, booster seats and seat belts. This guide is intended for anyone looking to implement an inspection station in their community.
- Distracted Driving Enforcement Demonstrations: Lessons Learned (PDF, 1.94 MB) December 2020; DOT HS 812 505
At any given daylight moment in America in 2017, some 481,000 drivers were using cell phones while driving. In that year 3,166 people died in crashes involving distracted drivers. In 2015 there were 391,000 people injured in distraction-affected crashes. In 2016 there were 457 fatal crashes that involved drivers with cell phones. Police crash reports said that in all these fatal crashes the drivers were talking on, listening to, or manipulating cell phones. The strategies and approaches in this guide focus on the complexity of the problem and enforcement strategies to combat texting while driving and cell phone use. “Distraction” includes several serious types of driver inattention such as eating, grooming, or talking to other passengers, among other causes. Two of the most common are texting and talking on a cell phone while driving. In 2016 more than 1.939 trillion text messages (SMS and MMS kinds) were sent in the United States. This guide describes three NHTSA-funded enforcement demonstration programs held at six sites, Hartford, Connecticut; Syracuse, New York; Sacramento Valley, California; Delaware; the southwest area surrounding Danbury, Connecticut; and a suburban area north of Boston, Massachusetts. Key lessons learned describe insights and ideas for law enforcement and State Highway Safety Offices to consider as tactics to combat distracted driving. These include spotters on overpasses and elevated roadways and using taller SUVs and trucks to get better elevated observation angles. Police know texting offenders frequently commit traffic violations such as lane departure, traveling too slowly, or weaving on high-speed highways. Targeted enforcement using stationary patrols, spotters, and roving patrols also result in high levels of observed violations.
Emergency Medical Services
- Characterizing Ambulance Driver Training in EMS Systems (PDF, 1.26 MB) December 2019; DOT HS 812 862
Reducing ambulance crashes due to human error is a priority for the National Highway Traffic Safety Administration. One possible way to address the issue is by limiting driver errors through ambulance operator education and training. Little, however, is currently known about existing practices. The primary objective of this project was to characterize ambulance operator education and training across the United States through discussions with personnel in State EMS offices and through an Internet-based survey of local EMS agencies to determine their operator training and supervision practices. The study also examined selected existing ambulance Emergency Vehicle Operator Course (EVOC) training programs to determine their content and consistency with the state-of-the-art. The results of this study suggest that most ambulance operators receive some form of training, but the survey responses and the review of existing EVOC training programs by subject matter experts suggest that the duration, content, and overall quality of the training may not be sufficient to have the desired impact on ambulance operator safety performance. A lack of state-level oversight and documentation limit the ability to make any definitive statements as to how many ambulance operators in each state are completing EVOC and which programs they are completing.
- Fatigue in Emergency Medical Services Systems (PDF, 558 KB) August 2019; DOT HS 812 767
This project produced five evidence-based guidelines (EBGs) for fatigue risk management tailored to Emergency Medical Services (EMS) operations using the National Prehospital EBG Model Process and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology. 1) Use fatigue/sleepiness survey instruments to measure and monitor fatigue in EMS personnel. 2) EMS personnel work shifts shorter than 24 hours long. 3) EMS personnel have access to caffeine as a fatigue countermeasure. 4) EMS personnel have opportunities to nap while on duty to mitigate fatigue. 5) EMS personnel receive education and training to mitigate fatigue and fatigue-related risks.
- Best Practices for Implementing a State Judicial Outreach Liaison Program (PDF, 1.4 MB) March 2019; DOT HS 812 676
This report was previously published under the title Guidelines for Creating State Judicial Outreach Liaisons, Report No. DOT HS 811 783, in July 2013. This edition was revised and re-titled in March 2019. It now has two parts: Part I is for the State Highway Safety Offices (SHSOs) and includes information on the scope and purpose of the State Judicial Outreach Liaison (JOL) program; Part II is focused on launching the program and includes information helpful to both the SHSO and the new State JOL. The criminal justice system plays a critical role in deterring unsafe driving behaviors and assigning appropriate consequences for impaired driving and other traffic offenses. From arrest to prosecution to sentencing, it is important that all stakeholders in the criminal justice system are aware of the efforts being made to reduce traffic fatalities. To that end, peer-to-peer training, education, and outreach are used in promoting proven and promising practices. NHTSA has supported the development of a network of criminal justice professionals who utilize peer-to-peer education.
- Law Enforcement Phlebotomy Toolkit: A Guide to Assist Law Enforcement Agencies With Planning and Implementing a Phlebotomy Program (PDF, 1.2 MB) March 2019; DOT HS 812 705
A law enforcement phlebotomy program is a proven strategy to mitigate the time and cost issues associated with drawing blood from drivers suspected of driving while impaired (DWI) and therefore obtain the evidence necessary to prosecute impaired drivers. This toolkit provides information and resources to aid state and local law enforcement agencies in the implementation of a law enforcement phlebotomy program. The information in this toolkit is compiled from existing, successful law enforcement phlebotomy programs.
- The Status of College Impaired Driving: A National Call to Action (PDF, 78.7 MB)
In this report, Students Against Destructive Decisions (SADD) worked to determine the scope of impaired driving among 18- to 24-year-olds on traditional and non-traditional college campuses, and developed strategies that can be used to address the problem. This required an extensive review of existing programs and literature on impaired driving among this demographic, and a comparison of implemented countermeasures to understand where programmatic gaps exist. Utilizing its College Leadership Council, SADD also conducted two listening sessions with college students to learn more about social norms on campuses today. Based on these findings, SADD determined that programming must be tailored to specific risk factors such as gender and age, focused on correcting social norms in order to reduce risky behavior, and deployed by students to achieve peer-led behavioral change. SADD also intends to work within existing university systems to add impaired-driving programs and education.
- Alcohol Ignition Interlock Use Rates Following Changes in Interlock Legislation (PDF, 1.47 MB) November 2020; DOT HS 812 989
Ignition interlocks are effective at preventing driving under the influence (DUI) of alcohol while installed on vehicles. However, the rate of interlock use is low relative to the numbers of DUI arrests and convictions, even in states that mandate interlock use for all DUI offenders. Accordingly, there is interest in identifying ways to increase interlock use, including by expanding the types of offenses for which an offender is eligible or required to use an interlock. This study examined how changes to interlock law affected interlock use in Florida and West Virginia. Each state had expanded the types of DUI offenses that result in mandatory or voluntary use of an interlock. The study compared the number of new interlock installations, interlocks-in-place (interlocks currently installed), installations as a proportion of those eligible to use interlocks, and lack of use or low use of the vehicles with interlocks, before and after the states modified their laws. The analyses found statistically significant increases in interlock use in both states after changes were made to their interlock laws. The Florida data showed increases of 21.8 percent in all DUI offenders mandated to install; 69 percent in first offenders mandated to install; 122.3 percent more installations overall; and 27.8 percent more installations for first offenders mandated to install. The West Virginia data showed an increase of 242 percent in interlock installations after a 2010 change in the interlock law, and an increase of 60 percent after a 2014 change to interlock law; however, the measure “interlocks-in-place” did not reveal changes, which may be due to limitations in the data used to capture the number of installations and removals. The results showed an increase in interlock installations after changes to DUI law expanded the types of DUI offenses, such as a “high-BAC” offense, that mandate or permit an alternative sanction, interlock use. This outcome, though not surprising, suggests that previously some offenders avoided enrolling in interlock programs. Results also showed that barriers to interlock use can emerge when the law requires that offenders fulfill obligations unrelated to their DUI charge to qualify for interlock programs, such as paying past fines or child support. Finally, the study highlights the importance of interlock data systems for states to track trends in interlock use and evaluate interlock programs.
- Drug and Alcohol Prevalence in Seriously and Fatally Injured Road Users Before and During the COVID-19 Public Health Emergency (PDF, 1.2 MB) October 2020; DOT HS 813 018
A gap in knowledge exists regarding drug use among drivers and other road users (pedestrians, bicyclists) who are seriously or fatally injured in crashes in the United States. This study examines the prevalence of alcohol as well as selected over-the-counter, prescription, and illegal drugs in the blood of seriously or fatally injured drivers and other crash victims near the time of their crashes before and during the COVID-19 public health emergency. Data was collected at Level 1 trauma centers and medical examiner offices. The 3,003 participants represent a convenience sample of roadway users who were seriously or fatally injured during the study period. Trauma centers and medical examiners made available small volumes of blood for toxicological analyses from the total collected during their normal clinical procedures. The results indicate drug prevalence was high among seriously and fatally injured roadway users before the public health emergency began and was even higher during, especially for alcohol, cannabinoids (active THC), and opioids. Drivers in particular showed significantly higher overall drug prevalence during the public health emergency, with 64.7 percent testing positive for at least one active drug, compared to 50.8 percent before. Drivers also showed an increase in testing positive for two or more categories of drugs going from 17.6 percent before to 25.3 percent during the public health emergency. Of particular note, active THC was more prevalent among drivers during the public health emergency than alcohol (32.7% versus 28.3%), and opioid use among drivers almost doubled from 7.5 percent to 13.9 percent. Overall, the results of this study suggest the highway safety community should be concerned about the impact of other drugs as well as alcohol. In particular, the observed cannabis and opioid prevalence rates before and during the public health emergency could be indicative of a growing problem. These findings are prevalence rates only and cannot be used to determine whether the people were impaired at the time of their crash.
- Motorcyclists’ Attitudes on Using High-Visibility Gear to Improve Conspicuity: Findings From a Focus Group Study (PDF, 3.13 MB) May 2019; DOT HS 812 704
In its Moving Ahead for Progress in the 21st Century (MAP-21) Act, Congress directed NHTSA to establish a cooperative program the National Cooperative Research and Evaluation Program (NCREP) to conduct research and evaluations of state highway safety countermeasures. NCREP was continued in the Fixing America’s Surface Transportation (FAST) Act. This program is administered by NHTSA and managed jointly by NHTSA and the Governors Highway Safety Association (GHSA). Each year, the states (through GHSA) identify potential highway safety research or evaluation topics they believe are important for informing state policy, planning, and programmatic activities. One such topic identified by GHSA, the reasons why motorcyclists use or do not use high-visibility gear, formed the basis for this project. Prior research on multi-vehicle motorcycle crashes suggests that difficulty detecting motorcycles is a relevant factor. A potential countermeasure to this phenomenon is for a motorcycle rider to wear high-visibility gear, especially at night or in low-light conditions. Yet, many riders do not wear high-visibility gear. This report describes a study that explored why riders choose, or do not choose, to wear high-visibility gear. Eighteen focus groups of 137 riders in Rockville, Maryland; Los Angeles, California; Austin, Texas; and Ann Arbor, Michigan, discussed their attitudes, beliefs and preferences regarding high-visibility gear. As much as possible, the groups consisted of riders of the same gender and who ride the same motorcycle type (cruiser, touring motorcycle, or sport motorcycle). Findings revealed that a minority of participants regularly wear high-visibility gear, and most of these cited a history of being in a crash or knowing others who had been in crashes with other vehicles as the reason for using high-visibility gear. Primary reasons for not wearing high-visibility apparel were objections to its appearance and the belief that it does not fit with their riding culture. Participants indicated that, to increase its acceptance among motorcyclists, the comfort and look of high-visibility gear must improve.

- Older Drivers’ Self-Regulation and Exposure (PDF, 1.42 MB) April 2020; DOT HS 812 930
This study’s goal was to gain insights into the extent to which older adults appropriately self-regulate their driving behaviors as their functional skills decline. The study examined relationships among functional abilities as assessed by a clinical test battery, behind the wheel (BTW) driving performance as measured during an on road evaluation, and naturalistic driving behaviors (exposure) captured by video and tracking devices over a month of naturalistic driving. Many of the functional assessment measures predicted performance on the BTW evaluation. Notably, reduced visual acuity and contrast sensitivity, as well as poorer scores on Trail Making Tests A and B, simple and choice reaction times, and Snellgrove Maze Test completion times reliably predicted worse BTW performance. Analyses of the exposure data showed that many of the participants who exhibited poorer performance on the functional and BTW assessments limited their driving to less demanding contexts. Worse functional and BTW performance were associated with participants’ driving lessons’ demanding driving contexts, especially higher speed and nighttime driving. The findings suggest that many people who experience functional declines may regulate to a certain extent when, where, and how they drive. However, some of those with the poorest functional and/or BTW scores did not appear to limit their driving.
- Activity Level, Performance and Exposure Among Older Drivers (PDF, 4.43 MB) September 2019; DOT HS 812 734
This project explored the relationship between the fitness of older people – operationalized through multiple measures of physical activity level and cognitive status – and their driving performance and exposure. A certified driver rehabilitation specialist conducted on-road evaluations for a study sample (n=67; mean age=78.6) recruited from senior residential communities in the vicinity of Chapel Hill, North Carolina. GPS and video recorders installed in study participants’ own vehicles collected naturalistic driving data for approximately one month. Functional status assessments included measures of head/neck/torso flexibility; lower limb strength, balance, and proprioception; visual search with divided attention; and executive function. Activity levels were gauged through the Phone-FITT questionnaire; the VO max questionnaire and body measurements; and a pedometer that participants wore around their ankle for a month to record active minutes per day, steps per day, gait speed, and daily distance. Because of their complementary nature, the physical activity measures were combined into a single, continuous scale ranging from 1 (lowest level of physical activity) to 100 (highest level of activity), termed the Unified Physical Activity Index (UPAI). Subsequent correlations between UPAI scores and road test scores (operational, tactical, strategic, and total) showed that, while higher physical activity levels generally were associated with better road test performance, in all cases relationships were very weak, accounting for less than 3 percent of the variance in the performance evaluations. Similarly, UPAI scores failed to account for more than 1.5 percent of the variance in multiple measures of trip frequency, distance, or time, or of scanning behavior as characterized by frequency of side glances and over-the-shoulder checks. Correlations between functional status measures and performance and exposure also were very weak; the strongest (inverse) relationships, accounting for about 5 percent of variance, were between head/neck flexibility and shoulder checks per minute and between trails B score and minutes of driving per day. Logistic regression found that Trails B and Snellgrove Maze Test scores significantly predicted pass/fail outcomes on the road test, and a multiple regression model relating trails B (and other variables) to driving minutes per day indicated that the trails B relationship was statistically significant.
Seat Belt Use
- Psychological Constructs Related to Seat Belt Use, Volume 1: Methodology Report (PDF, 840 KB) December 2020; DOT HS 813 032
The Psychological Constructs Related to Seat Belt Use (PCRSBU) survey was designed to “go beyond” demographic correlates of seat belt use (e.g., age, income, race) and identify psychological constructs that may help explain additional variance in seat belt use among the general U.S. population. The survey was administered in 2018 to a representative sample of U.S. residents 16 or older who reported driving or riding in a car in the past year. This volume, methodology, is the first of two describing the survey and its results. Volume 2 is the results report.
- Psychological Constructs Related to Seat Belt Use, Volume 2: Results Report (PDF, 906 KB) DOT HS 813 029; December 2020
The Psychological Constructs Related to Seat Belt Use (PCRSBU) survey was designed to “go beyond” demographic correlates of seat belt use (e.g., age, income, race) and identify psychological constructs that may help explain additional variance in seat belt use among the general U.S. population. The survey was administered in 2018 to a representative sample of U.S. residents aged 16 years or older who reported driving or riding in a car in the past year. Analyses of survey results demonstrated that people with greater willingness to delay gratification, greater life satisfaction, more aversion to risks, greater perception of risk in various driving situations, greater loneliness, and more resistance to peer influence were more likely to be full-time seat belt users. People with greater impulsivity and inclination to engage in risky behaviors as acts of “social resistance” were less likely to be full-time belt users. Additionally, mediation analyses revealed that the psychological constructs fully explained some of the observed effects of demographic variables (age, sex, and one regional difference) on seat belt use. The results of this study may be useful both for identifying people at higher risk of seat belt non-use and for developing countermeasures targeted at high-risk occupants. The current volume is the second of two volumes describing the survey and the results. The other report is Volume 1: Methodology Report.
- Characteristics and Predictors of Occasional Seat Belt Use Using Strategic Highway Research Program 2 Data (PDF, 3.93 MB) February 2020; DOT HS 812 840
The National Highway Traffic Safety Administration estimates that despite the recent trend towards higher national seat belt use rates, 10% of drivers still only use seat belts occasionally. The current study examined occasional seat belt use among participants in the Strategic Highway Research Program 2 (SHRP2) Naturalistic Driving Study. The study was exploratory research with the specific objectives of: (1) identifying individual factors that differentiate seat belt user groups, and (2) identifying the impact of situational factors in seat belt use patterns of occasional seat belt users. Seat belt use data were available for 895 SHRP2 participants, and researchers examined belt use within and across each driver’s trips. Approximately 10 percent of study participants were clearly occasional seat belt users. The data provided evidence for two types of occasional seat belt users: those who made a pre-trip decision to buckle or remain unbuckled for the entire trip, and those who made a within-trip decision to buckle or unbuckle for part of the trip. Occasional seat belt users were more likely to be older and male, in addition to differing across several other demographic and psychological variables. Situational factors, such as trip distance, average speed, and start time also predicted occasional seat belt use.
- Education on Proper Use of Seat Belts on School Buses (PDF, 856 KB) January 2021; DOT HS 812 999
NHTSA sponsored this project to understand how school districts that purchase large school buses with seat belts can maximize their effectiveness and benefit by improving proper usage. The project obtained observational data on the impact of seat belts on student behavior on buses and on bus driver distraction. It examined how policies were carried out by school bus drivers, and consequences for non-compliance. In general, the most important factors were training, education, and enforcement. Most survey respondents said seat belts on school buses contributed to calmer and less distracted environments for school bus drivers.
- Analysis of SHRP2 Speeding Data (PDF, 6.40 MB) March 2020; DOT HS 812 858
Speeding-related crashes continue to be a serious problem in the United States and attempts to address this problem through a variety of approaches have not led to a substantial reduction in speed-related fatalities. A better understanding of speeding behavior is needed to inform the development of new speeding countermeasures. To address this issue, researchers conducted an in-depth investigation of driver speeding behavior using SHRP2 NDS data, which included numerous observations across various situations, environments, and driver characteristics. The research activities encompassed several steps. Sampling and data processing activities were conducted to obtain a set of trips that was suitable for examining multiple aspects of speeding. Key measures were then extracted from the trip data, including: (a) periods in which drivers had an opportunity to speed (which served as an exposure measure), and (b) speeding episodes within those periods. Using these data elements, situational and driver-specific predictors of speeding were examined using descriptive statistics and regression analyses. In addition, speeding episodes were used to identify different types of speeding and to develop a typology of speeders. Five types of speeders were identified, and these groups differed in terms of their aggregate speeding behavior, demographic characteristics, and attitudes about speeding and risk taking.
- Analysis of SHRP2 Speeding Data: Methods Used to Conduct the Research (PDF, 3.76 MB) March 2020; DOT HS 812 793
This report describes the methodologies and datasets used to prepare a set of data reductions that supported analyses of speeding behavior as discussed in the Findings Report from the same study (Richard, Lee, Brown, & Landgraf, 2019). Importantly, it 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. The report focuses primarily on the methods used to (1) obtain and process trip time series data, (2) prepare data reductions to extract free flow episodes (FFE) driving in free flow conditions where drivers have the opportunity to speed and (3) extract speeding episodes (SE). The workflow for preparing the data reductions consisted of three components: data acquisition, data management, and data processing. Data acquisition consisted of identifying variables of interest, selecting variables, obtaining a data sharing agreement, preparing and submitting data requests, and retrieving data extracted by the SHRP2 data contractor (VTTI). Data management included tracking the status of each trip during processing; retrieving, manipulating, and storing data in a relational database management system; database administration; data security; and data quality management. Data processing included developing and implementing data processing software tools that cleaned the data; parsed them into Trips, FFEs, and SEs; and produced data reductions suitable for analysis. Lessons learned during the conduct of the research are provided.
- Young Driver Survey (PDF, 3.09 MB) October 2019; DOT HS 812 761
The overrepresentation of young drivers in crashes and road fatalities is a serious public health concern and imposes substantial human, social, and economic costs. Contributing factors to crash risk include exposure, inexperience, distraction, recklessness, and social influence from peer passengers. Fortunately, young driver motor vehicle crashes are preventable, and proven strategies can improve the safety of young drivers on the road. The Young Driver Survey explored traffic safety attitudes and beliefs of young people 16 to 21 years old residing in Florida, Georgia, Massachusetts, Nebraska, and Oklahoma. This questionnaire explored issues with the driving experiences of younger drivers and identified key challenges to safety measures. About 18,000 respondents (n = 17,698) completed the survey.
