Research Overview
 

Meghan is currently involved in two research projects. The first of these projects is working on a team to research the consequences of driver distraction on situational awareness. With the overwhelming popularity of in-vehicle information systems, concerns have been raised as to how these may affect driver attention to the roadway and consequently, driver safety. Many previous studies have shown that distractions have a negative effect on driver performance; however, these studies focus on performance outcome measures and not the effects on driver cognitive functions that may drive performance. The objective of the driving simulation study is to understand how visual and cognitive distraction affects driver situation awareness (SA) and, consequently performance.

Meghan’s second project is to analyze the effects of nine panel logo signs on driver visual distraction and performance. At many interchanges on North Carolina freeways, the number of businesses providing certain services exceeds the current maximum permissible number of panels per logo sign (six). In 2005, the North Carolina Department of Transportation (NCDOT) began experimenting with nine-panel signs at some of these locations. However, current DOT policy (the Manual on Uniform Traffic Control Devices) maintains that “no more than six logo sign panels shall be displayed on a single specific service sign.” A concern of some highway system researchers is that more signs or signs with more information might add to driver distraction. The present study will extend previous research by determining whether increased glances or scans of signs along the highway cause distractions that adversely affect driver ability to safely navigate on roadways.

Meghan also spends time each week working at the Ergonomics Center of North Carolina on a variety of projects.

 


January 2010


Meghan helped Dr. Buckner of the Mechanical Engineering department by aiding his daughter with her research on texting while driving. Meghan supported the research by operating the STISM driving simulator.

February 2010


Meghan continued her work with the driver distraction study by finalizing the code for one of the driving tasks, developing a plan for data reduction of the situational awareness probes, and helping recruit subjects.
Meghan also started work on a project to assess veterinary hospital ergonomics by visiting the facility and collecting data from interviews and standard operating procedures to complete a task analysis of their current work practices.

March 2010


Meghan continued her work with the driver distraction study by running recruited subjects through the experiment. Once the data was collected, Meghan worked on the Situational Awareness probes data reduction. For her veterinary hospital project, Meghan continued work by analyzing a variety of commonly performed tasks and determining the frequency and severity of risks of WMSDs to which workers are exposed. Once the high risk jobs were determined, Meghan worked with her teammate to provide recommendations of ergonomic interventions.

April 2010


Meghan completed her veterinary hospital project by writing the final report for the Triangle Veterinary Emergency Clinic. She has continued to work on the data reduction and statistical analysis of the SA probes from the driving experiment. Also, she has started a new project working with The Ergonomics Center of North Carolina to aid in job screenings for the Perdue chicken processing plant.

August 2010


Meghan began her work on the nine panel logo sign project by attending interdisciplinary team meetings and drafting the study plan for the experiment. Meghan also worked on the driver distraction project by working on a journal article of the findings.

September 2010


Meghan finalized the study plan for the nine panel logo sign and presented it to the NCDOT for review. She also submitted an abstract based on the research from her previous small animal veterinarian clinic project to the 2011 Applied Ergonomics Conference and attended the 54th Annual HFES Meeting.

October 2010


Meghan continued her work on the nine panel logo sign project by formulating and submitting the IRB protocol. She also wrote and submitted an abstract to the 2011 HCI International conference based on the situation awareness results from the driver distraction study.

Meghan also attended a workshop on using the Lumbar Motion Monitor in the Ergonomics Lab.

November 2010


Meghan worked on reviewing the literature for the nine panel logo sign project in order to determine an acceptable legibility distance for which to start capturing eye tracking data. She also wrote the participant instructions script for the experiment. She continues to work with a teammate to finalize the journal article based on the research completed during the driver distraction study.

December 2010


Meghan helped finalize the experiment set-up for the nine panel logo sign project. The team ran pilot participants and began scheduling and running test participants during December.

January 2011


Meghan submitted an article to the IIE magazine based on her work studying ergonomic risk factors in small animal veterinarians. The article is scheduled to be published in the March edition. She also drafted a paper based on the situation awareness results from the driver distraction study to be published in the 2011 HCI International conference proceedings.

Meghan continues to run participants for the nine panel logo study as well as spend her time helping at the Ergonomics Center of North Carolina.

February 2011


As part of the nine panel logo sign team, Meghan finished running participants through the simulator experiment. She also started analyzing the collected data, as well as began drafting the final report for the DOT project. Specifically, Meghan transferred the video files collected for all participants into audio files and started breaking down each audio file to determine at what point in the simulator trial the participant was able to identify a target business panel logo. Meghan also worked on collecting the signal detection data measured as part of determining any effect logo sign type has on signal detection performance.

Meghan also began collecting data for her thesis assessing the risk factors for work related musculoskeletal disorders seen in large animal veterinarian tasks. Along with the help of fellow NIOSH trainee, Kinley Taylor, Meghan began shadowing a variety of equine veterinary services offered at the Veterinary Teaching Hospital located at the College of Veterinary Medicine of North Carolina State University.

Meghan finalized and submitted two conference proceedings papers, one for the Human Computer Interaction International conference and a second for the Applied Ergonomics Conference. These papers will be published as part of the conference proceedings.

March 2011


Meghan continued her work as part of a team project for the NCDOT by aiding with data reduction and analysis. Also, she was one of the leads on the report write-up. The report and final presentation will be given to the DOT in the near future.

Meghan attended the Applied Ergonomics Conference where she presented her work on the ergonomic risk factors at a small animal veterinarian clinic. She also continued to collect data for her thesis by shadowing the equine veterinarians at NCSU's College of Veterinarian Medicine.

Meghan worked on a team to conduct a literature review for a project being conducted by the Ergonomics Center of North Carolina as well as helping formulate design requirements for a software revision. Finally, she completed a team journal write up for a paper on the optimal monitor position in endoscopic surgery. The paper is currently being revised for a journal submission.

April 2011


Meghan helped finalize the initial draft report on the logo sign project. This report was sent to the NCDOT for review. Along with the report, the project and its outcomes were shown to the NCDOT by means of a final presentation. Currently, journal articles are being prepared by the team.

Meghan also worked on a project for the Ergonomics Center that included a literature review used to build a presentation on the background of ergonomics and the benefits of implementing an ergonomics program.

Meghan and Kinley began data analysis involving subjectively screening the videos they had collected to identify potential risk factors in equine veterinarian daily tasks.
