    Case Study on the Impact of Treating Sleep Apnea in Commercial Motor Vehicle Drivers: Sleep Apnea Programs from Two Leading U.S. Carriers and Focus Group Findings
    Mabry, J. Erin; Baker, Stephanie Ann; Hickman, Jeffrey S.; Hanowski, Richard J. (National Surface Transportation Safety Center for Excellence, 2012-09-28)
    Approximately one in four commercial motor vehicle (CMV) drivers in the U.S. are estimated to possess mild or higher levels of obstructive sleep apnea (OSA), the most common sleep-breathing disorder that is associated with significant medical consequences (including cardiovascular disease and diabetes). A major symptom of sleep apnea is excessive daytime sleepiness, which is highly correlated to impaired driving performance and may result in an increased risk of being in traffic--or work-related incidents. The most prescribed and cost-effective first-line treatment for OSA is nasal continuous positive airway pressure (CPAP). Two leading U.S. carriers partnered with commercial sleep apnea providers to implement obstructive sleep apnea (OSA) programs that screen, diagnose, treat, and manage their OSA-positive CMV drivers. This case study provides an overview of these OSA programs; outlines each carrier's screening, testing, and compliance protocols; and compares and contrasts their approaches. Focus group research was also conducted with drivers and staff involved in each program to assess their perceptions and opinions of their respective OSA programs. While the majority of drivers expressed overall satisfaction participating in their carrier's OSA program, both drivers and staff stressed the difficulty of healthy eating, exercise, and weight loss as adjunct OSA treatments. Finally, staff expressed the importance of coordination between the carrier and the OSA provider to provide driver support.

    Consumer Driving Automation System Education: A Learning and Retention Assessment
    Trimble, Tammy E.; Baker, Stephanie Ann; Russell, Sheldon M.; Tidwell, Scott (National Surface Transportation Safety Center for Excellence, 2020-07-08)
    For the potential safety benefits of driving automation systems to be fully realized, drivers must understand the capabilities and limitations of these systems. This study explored a range of materials that drivers may access when trying to learn about driving automation system safety features: owner’s manual only, owner’s manual and OEM website video or animation, and owner’s manual and MyCarDoesWhat.org videos. Three vehicles, a 2015 Infiniti Q50, a 2016 Honda CR-V, and a 2015 Chevy Tahoe, were selected to represent a range of vehicle types, sizes, technologies, and price points. Each training condition was tested with each vehicle for a total of nine possible testing scenarios. Thirty-six participants were recruited for the study, with an equal number of males and females from two age groups, 25–39 and 40–54 years old. Participants were balanced across the nine possible testing scenarios. A two-part study was conducted to assess participants’ ability to learn from existing training materials and to determine how well participants were able to retain what they learned. When taking into consideration participants’ self-reported learning styles, average scores across all technologies were fairly comparable across style, and participants were able gain at least a rudimentary understanding of the operation and purposes of driving automation system technologies. However, participants were less sure of the specifics associated with the technologies (i.e., activation, alerts or warnings, and appropriate use). Those in the multimedia testing conditions reported feeling more familiar with the technologies than those in the owner’s manual only condition. Participants found the videos to be an entertaining and easier-to-understand alternative to the manual. Several indicated that they would refer to the video first to see how the technology worked and then refer to the manual to gain a more in-depth understanding. Videos with sound and additional details were preferred to the simpler animations.

    Development of Curriculum for the Virginia Driver's Licensing Ceremony
    Duke, Rebekah; Klauer, Charlie; Baker, Stephanie Ann (National Surface Transportation Safety Center for Excellence, 2017-12-06)
    In Virginia, to receive the actual driver’s license (as opposed to the temporary driving permit), both a parent and the teenage driver must appear before a family district court judge and participate in the Virginia Driver’s Licensing Ceremony. This is an opportune moment when safety information is disseminated to parents and their novice drivers. These ceremonies are written and created primarily by district court judges. While some judges have taken a great deal of time and compiled excellent information, others are unsure about the information that should be relayed. The purpose of this project was to develop a PowerPoint presentation and handout based on contemporary teen driving research and to disseminate the materials to district court judges throughout the state of Virginia for use in their licensing ceremonies. The PowerPoint presentation included the slides but also was accompanied with a script for the judges to use during the presentation. The slides and script provide parents and teens with key safety information, including the driving risks teens face, the Graduated Driver Licensing (GDL) laws in Virginia, and how to use a parent-teen driving contract as a mechanism for risk reduction and parental management.

    Draft Final Report: Development of Hazardous Materials (HM) Shipper Prioritization Program
    Schaudt, William A.; Bowman, Darrell Scott; Marinik, Andrew; Baker, Stephanie Ann; Trimble, Tammy E.; Hanowski, Richard J. (Virginia Tech Transportation Institute, 2009-02-28)
    In the mid-1990s, an attempt was made to develop a performance-based prioritization for Hazardous Materials (HM) shippers. During this attempt it became apparent that there was insufficient performance data to develop such a system. In response, FMCSA developed the HM Package Inspection Program (HMPIP) to focus on inspecting individual shipments of HM at the roadside or on carriers’ docks. Due to the improvements made over the years to the package inspection data collected during HMPIP inspections, HM incident data, and improved departmental data identifying companies involved in shipping HM, FMCSA has begun a second effort to develop a performance-based prioritization of HM shippers. The purpose of the current project was for the Virginia Tech Transportation Institute (VTTI) to review, document, and recommend improvements to FMCSA’s HM Shipper Prioritization Program. This project consisted of six major tasks, all of which were successfully executed by VTTI. After the kick-off meeting and the successful completion of a detailed work plan, a peer review committee was formed. Members of the peer review committee were to participate in two peer review meetings during the course of the project. The purpose of the first peer review meeting was to have the study methodology and data collection techniques reviewed by the committee. The purpose of the second peer review meeting was to review the study findings and conclusions. Another major step in this project was to review and examine the current Hazardous Materials (HM) Shipper Prioritization Program, which included two distinct prioritization algorithms, and to develop software titled the HM Shipper Prioritization Application (HMSPA). HMSPA was then beta tested in states with existing shipper programs. The focus of these onsite tests was usability testing with potential end users. Both subjective and objective data were collected by way of questionnaires and performance tasks. All results were very positive indicating that the beta version, with minor modifications based on user recommendations, should move forward into a fully functioning application for FMCSA.

    Driver Coach Study: Using Real-time and Post Hoc Feedback to Improve Teen Driving Habits
    Klauer, Charlie; Ankem, Gayatri; Guo, Feng; Baynes, Peter; Fang, Youjia; Atkins, Whitney; Baker, Stephanie Ann; Duke, Rebekah; Hankey, Jonathan M.; Dingus, Thomas A. (National Surface Transportation Safety Center for Excellence, 2017-12-08)
    Novice teenage drivers have the highest rates of fatalities and injuries on U.S. roadways compared to any other age group. This experimental research was conducted to see if presenting novice teenage drivers and their parents with feedback on teen driving performance could decrease rates of crash/near-crash (CNC) involvement. Ninety-two newly licensed teens had their vehicles instrumented with a data acquisition system (the Virginia Tech Transportation Institute’s MiniDAS) and received driving feedback in the form of a light and a tone when a potentially risky behavior was detected. Behaviors, such as swerving, speeding, lane changing without a turn signal, hard braking, hard turning, and fast starts, were used to determine when feedback was administered. Feedback continued for six months and then was turned off for one month (in the seventh month) to determine if risky behaviors returned after feedback stopped. These data were compared to a separate study (the Supervised Practice Driving Study [SPDS]) of 90 teenage drivers in the same geographic location who did not receive feedback. Parental involvement was examined by tracking which teen/parent groups checked the website and which did not. Results suggest that real-time and post hoc feedback produce a relative reduction in the rate of CNC involvement, but only when the parent is logging in to the website. If parents do not log in to the website to review the coachable events, real-time and post hoc feedback do not improve CNC rates. The analyses also indicated that once feedback was turned off in Month 7, teen CNC rates returned to baseline levels, which suggests that 6 months of feedback is not enough time to instill safe driving habits in novice drivers. This result also suggests that parental involvement in driver education must continue through the independent driving phase to improve teen CNC rates. In general, these results support previous research on monitoring and feedback, which suggest that parental involvement is critical in improving teen driving safety. These results also support current Graduated Driver’s Licensing (GDL) policies and provide research-based evidence that these policies should be strengthened.

    Enhanced Rear Signaling (ERS) for Heavy Trucks: Phase III – Development of Field Operational Test
    Schaudt, William A.; Bowman, Darrell Scott; Trimble, Tammy E.; Medina, Alejandra; Bocanegra, Joseph L.; Baker, Stephanie Ann; Marinik, Andrew; Wierwille, Walter W.; Hanowski, Richard J. (Virginia Tech Transportation Institute, 2010-09)
    The Enhanced Rear Signaling (ERS) for Heavy Trucks project was directed at investigating methods to reduce or mitigate those crashes where a heavy truck has been struck in the rear by another vehicle. Prior to the current effort, two phases of work had been completed on this project. The purpose of the current effort, Phase III, focused on exploring the benefits of the countermeasures developed in previous phases, and to develop a plan for a large scale Field Operational Test (FOT). During crash database analyses in the current project it was found that, in 2006, there were approximately 23,500 rear-end crashes involving heavy trucks which resulted in 135 fatalities and 1603 incapacitating injuries. Many different types of ERSs were investigated in this study across both the auditory and visual modalities. Visual warning signals were found to be the most beneficial at signaling following-vehicle drivers (more specifically rear warning-light configurations). The research team recommended that one specific configuration be selected for real-world data collection based on its high performance and the potential success of future design implementation. Overall, the final radar-based cautionary ERS system was robust in real-world driving conditions and is recommended for an FOT.

    Establishing a Methodology to Evaluate Teen Driver-training Programs
    Trimble, Tammy E.; Baker, Stephanie Ann; Schaudt, William A.; Schrader, Taryn (Wisconsin. Department of Transportation. Library and Research Unit, 2013-11)
    The goal of this research project was to develop a methodology to assist the Wisconsin Department of Transportation (WisDOT) in the evaluation of effectiveness of teen driver education programs over the short and long terms. The research effort was divided into two phases. Phase I focused on the development of an evaluative methodology that was based upon a review of the relevant literature and Wisconsin-specific policies and available data sources. This review culminated in a program assessment tool focused on four contributing areas of teen driver training and education: 1) Guardian Involvement, 2) Driver Education and Training Curricula Requirement, 3) GDL Coordination, and 4) Instructor Qualifications. The proposed methodology was presented to the Project Oversight Committee and was validated through two rounds of pilot testing using materials provided by programs and schools under the oversight of both WisDOT and the Wisconsin Department of Public Instruction. The resulting methodology informed the Phase II implementation plan recommendations. Work products included within this report are an annotated bibliography, a knowledge base documenting best practices and Wisconsin-specific data source, a methodology that may be used to analyze and evaluate the effectiveness of driver-training programs as they relate to the demonstrated safety and behavior of teen drivers in Wisconsin, and a three-phase implementation plan.

    Evaluation of Light-Vehicle Driver Education Programs Targeting Sharing the Road with Heavy Vehicles: A Case Study Analysis
    Baker, Stephanie Ann; Schaudt, William A.; Joslin, Spencer; Tidwell, Scott; Bowman, Darrell Scott (National Surface Transportation Safety Center for Excellence, 2014-10-16)
    The purpose of this case study project sponsored by the National Surface Transportation Safety Center for Excellence (NSTSCE) was twofold. First, researchers investigated current light-vehicle driver education programs that contain components on sharing the road with heavy vehicles and developed a supplemental practices document on key sharing-the-road information that teachers could cover with students. Second, a case study was performed with a light-vehicle driver education program in a single state that only included a basic textbook-based component on sharing the road with heavy vehicles. Two components were introduced into different driver education classrooms and evaluated in comparison with the basic textbook-based component. The first component introduced was updated material in the form of a DVD developed by the Commercial Vehicle Safety Alliance titled Teens and Trucks. The second component introduced was a hands-on truck experience program developed by NSTSCE researchers. Each classroom of students that received one of the components was invited to take part in a survey two months later and knowledge retention of key learning points (e.g., heavy vehicle No-Zones) was measured. Focus groups were also conducted with students to explore learning preferences related to driver education, understanding of key sharing-the-road information, and ratings of the various components. The mean percentage of correct responses for all survey questions was calculated and compared across the three conditions and did not show a statistically significant difference in knowledge retention of any one condition over another. Further analyses were performed to evaluate each survey question individually across conditions. Results found only one statistically significant difference: the textbook and truck condition outperformed the textbook condition regarding the proper front No-Zone distance. Although only one survey question analyzed for knowledge retention resulted in a statistically significant difference, students and teachers found the supplemental DVD and truck hands-on demonstration to be helpful, in particular the truck experience. The conclusion would seem to be that if a truck and driver are available teachers should try to include a truck hands-on experience when teaching sharing the road with trucks. Students are likely to find it helpful and preferable to just reading about sharing the road in their textbook.

    Examining Senior Drivers Adaptation to Mixed Level Automated Vehicles: A Naturalistic Study
    Liang, Dan; Antin, Jonathan F.; Lau, Nathan; Stulce, Kelly E.; Baker, Stephanie Ann; Wotring, Brian (SAFE-D: Safety Through Disruption National University Transportation Center, 2019-08)
    Advances in the development of advanced vehicle technologies (AVTs), such as blind spot alerts, lane keep assist,lane alert, and adaptive cruise control, can benefit senior drivers by reducing exposure to hazards andcompensating for diminished cognitive abilities sometimes seen in this population. However, the degree to whichsuch benefits can be realized in this vulnerable population depends largely on the degree to which senior driverswill accept, adopt, and adapt to these features. This study investigated how 18 seniors, aged 70–79, accepted,trusted, and used mixed-function AVTs when provided an AVT-equipped vehicle to drive as they desired for a 6-week period. Researchers assessed attitudes and the effect of exposure via before-and-after exposure surveys, briefweekly check-in surveys during the driving exposure period, and focus group sessions conducted after theconclusion of the driving exposure period. Analyses revealed that seniors prefer technologies that inform, such asblind spot alert, over those that assert independent control over the vehicle, such as lane keep assist. Increasedconfidence in and willingness to use AVTs correlated positively with exposure, with adequate time for orientationand appropriate user documentation emerging as key factors determining senior drivers’ acceptance.

    Examining senior drivers' attitudes toward advanced driver assistance systems after naturalistic exposure
    Liang, Dan; Lau, Nathan; Baker, Stephanie Ann; Antin, Jonathan F. (Oxford University Press, 2020-01-01)
    Background and Objectives: The increasing number of senior drivers may introduce new road risks due to age-related declines in physical and cognitive abilities. Advanced driver assistance systems (ADAS) have been proposed as solutions to minimize age-related declines, thereby increasing both senior safety and mobility. This study examined factors that influence seniors' attitudes toward adopting ADAS after significant exposure to the technology in naturalistic settings. Research Design and Methods: This study recruited 18 senior drivers aged 70-79 to drive vehicles equipped with ADAS for 6 weeks in their own environments. Afterward, each participant was enrolled in 1 of the 3 focus group sessions to discuss their changes in attitude toward ADAS based on their driving experiences. We applied structural topic modeling (STM) on the focus group transcripts to reveal key topics deemed important to seniors. Results: STM revealed 5 topics of importance for seniors. In order of prevalence, these were (i) safety, (ii) confidence concerning ADAS, (iii) ADAS functionality, (iv) user interface/usability, and (v) non-ADAS-related features. Based on topics and associated keywords, seniors perceived safety improvement with ADAS but expressed concerns about its limitations in coping with adverse driving conditions. Experience and training were suggested for improving seniors' confidence in ADAS. Blind spot alert and adaptive cruise control received the most discussion regarding perceived safety and comfort. Discussion and Implications: This study indicated that promoting road safety for senior drivers through ADAS is feasible. Acceptance and appropriate use of ADAS may be supported through intuitive and senior-friendly user interfaces, in-depth training programs, and owner's manuals specifically designed and tested for senior drivers.

    Baker, Stephanie Ann; Hintz, Rewa; Trimble, Tammy E. (United States. Federal Highway Administration, 2002-05)
    The purpose of this report is to document the historical development of the Travel Shenandoah pilot project. This report will not attempt to describe in detail the entire five-year history; rather it will focus on the major events that helped evolve the program into what it is now. The history covers the period from pre-deployment in 1997, through the evolution of the service into 511 Virginia in February 2002. By analyzing past documents, a history has been developed and is presented in chronological format in this report. This history will become the background for a formal evaluation of the new 511 Virginia service, formerly Travel Shenandoah. There are three sections to this report. The first section is a summary of the original pilot Travel Shenandoah Service. The second is a history from 1997 to 2002, including a brief description of the new 511 Virginia service. The final section is a discussion of the evolution of the Travel Shenandoah business model.

    Koper Curve Principle for Commercial Motor Vehicle (CMV) Traffic Enforcement
    Baker, Stephanie Ann; Trimble, Tammy E. (National Surface Transportation Safety Center for Excellence, 2023-08-15)
    The Koper curve principle postulates that crime deterrence can be improved with an optimal dosage of police presence at hot spot locations. With the goal of better understanding how to reduce commercial motor vehicle (CMV) crashes, a literature review was conducted to explore whether the Koper Curve principle has ever been applied to efforts aimed at reducing CMV crashes, and if so, how it was applied. In conducting the literature review, several related domains (deterrence, evidence-based policing, and high-visibility enforcement) were also considered as they apply to the use of the Koper Curve for CMV crash reduction. The literature related to the Koper Curve focused primarily on crime deterrence (e.g., robbery), not crash reduction. The literature review revealed one ongoing study that is using the Koper Curve principle toward the goal of reducing CMV crashes on specific interstate corridors (Kentucky Research Center, 2023). Two examples, from Nashville, Tennessee, and São Paulo, Brazil, showed the Koper Curve being applied to crash reduction more generally (not specific to CMVs), which may inform how the Koper Curve could be used to reduce CMV crashes. The literature provided a few best practices that may be helpful to practitioners seeking to reduce crashes in high-risk corridors: (1) use data to target behaviors leading to crashes; (2) use data to identify hot spots where crashes are occurring; (3) provide instruction to officers on how to conduct high-visibility enforcement; and (4) evaluate the enforcement effort.

    Parent Perceptions of Real-Time and Non-Video Feedback from the Driver Coach Study
    Baker, Stephanie Ann; Klauer, Charlie; Baynes, Peter; Dingus, Thomas A. (National Surface Transportation Safety Center for Excellence, 2020-04-24)
    Motor vehicle crashes are the leading cause of death for teens. Research indicates that an effective way to improve teen safety is through the use of in-vehicle monitoring devices that provide feedback to teens and parents. Monitoring devices provide teens with real-time feedback on their driving behavior and parents with post hoc feedback that allows them to monitor their teen and coach them as they learn to drive. The aims of this analysis were to understand if the parents of teens who participated in the Driver Coach Study utilized the non-video feedback tools on the website and to summarize their opinions about the real-time and non-video feedback provided. Key takeaways were that (a) training would help parents and teens make the most of the tools available to them, (b) real-time feedback was seen as beneficial at improving teens’ driving, (c) monitoring systems should notify parents when post hoc feedback is available, and (d) non-video monitoring tools such as graphs and coaching notes should be informative and provide a comments section for user feedback.

    A survey of light-vehicle driver education programs to determine the prevalence of curriculum on sharing the road with heavy vehicles: final report
    Baker, Stephanie Ann; Schaudt, William A.; Freed, J. C.; Toole, Laura (National Surface Transportation Safety Center for Excellence, 2011-12-01)
    Light-vehicle driver education programs that contain content about heavy-vehicle operation may be helpful in reducing light-vehicle/heavy-vehicle interactions. However, it is unclear as to the extent of current state curricula requirements, content, and perceived effectiveness (for both public and private programs) regarding heavy-vehicle operation and associated light-vehicle driving recommended procedures. This project involved the development of an online survey targeted at instructors and/or administrators of individual state driver education programs to identify current curricula addressing heavy vehicles (or lack thereof) and perceived effectiveness. Also, an attempt was made to locate driver education curricula and/or manuals from every state to better understand if instructors in every state have access to information on how light vehicles can safely share the road with heavy vehicles. -- Report website.

    Synthesis of Literature and Operating Safety Practices Related to Cell Phone/Personal Data Assistant Use in Commercial Truck and Bus Operations (Technical Report)
    Morgan, Justin F.; Trimble, Tammy E.; Bowman, Darrell Scott; Baker, Stephanie Ann; Pickett, Raquel; Murray, Dan; Bergoffen, Gene (United States. Federal Motor Carrier Safety Administration, 2011-04)
    There is an increasing awareness of the role of driver distraction in commercial motor vehicle crashes. This study presents the results of efforts to expand current knowledge of truck and motorcoach industry practices regarding commercial driver distraction. The project involved a thorough literature review on driver distraction. Little research specifically addressed commercial driver distraction; those studies that did examine commercial driving typically found significant degradations in driver performance due to visually demanding device use. However, the findings of automotive driver distraction research vary based on the type of examination (i.e., simulator, test-track, or naturalistic data collection methods) and the aspect of phone use. These findings, in light of the importance and potential safety risks posed by driver distraction, may help guide further research into the nature and magnitude of distraction faced by CMV drivers as part of their normal job functions.

    Tips for Sharing the Road with Commercial Motor Vehicles: A Web-Based Approach
    Dunn, Naomi J.; Baker, Stephanie Ann; Blanco, Myra (National Surface Transportation Safety Center for Excellence, 2016-01-11)
    This report documents the Tips for Sharing the Road with Commercial Motor Vehicles website (http://www.cmvroadsharing.org). The website was created by the National Surface Transportation Safety Center for Excellence to educate teen drivers about how to share the road with heavy vehicles. The website incorporates video clips of real-world driving events captured during a naturalistic driving study conducted by the Virginia Tech Transportation Institute (VTTI). The video clips provide examples of both proper and improper driving behavior. The rationale for providing examples of both types of behavior was that effective education of drivers, especially those who are young and inexperienced, needs to show not only “what not to do,” but should also illustrate the alternative “correct” road sharing behavior. The naturalistic driving video clips shown on the website are all from the truck driver’s perspective to highlight the difficulties these drivers face on the road every day due to other drivers’ improper road sharing behavior.

    Vehicle-width Measurement Technology Development: Phase I Technical Memorandum
    Marinik, Andrew; Trimble, Tammy E.; Baker, Stephanie Ann; Bryson, Jared; Schaudt, William A.; Bowman, Darrell Scott (Virginia Center for Transportation Innovation and Research, 2011-08)
    The Virginia Tech Transportation Institute (VTTI) was tasked with investigating the feasibility of developing a vehicle-width measurement and alert system to reduce over-width violations in Virginia Department of Transportation’s (VDOT) work zones. A two-phase approach was developed to investigate the measurement system feasibility. During Phase I, the focus of the current report, VTTI first generated design criteria with support from stakeholders (i.e., the Virginia Center for Transportation Innovation and Research [VCTIR] and VDOT). Next, researchers and engineers assessed existing vehicle-width measurement systems against these criteria to determine design gaps, and then explored solutions (e.g., new technologies) to these design gaps. Identified potential solutions were then tested on the Virginia Smart Road. In the end, VTTI developed a preliminary system architecture for a vehicle-width measurement system. Based on the findings of this research effort three recommendations are offered to guide future development of a vehicle-width measurement system.
