The final report for Human Factors Evaluation of an In-Vehicle Active Traffic and Demand Management (ATDM) System, submitted by Kayla Sykes, M.S., has been released.

Report Abstract:

This research study focused on the development and subsequent evaluation of an in-vehicle Active Traffic and Demand Management (ATDM) system deployed on Interstate 66 in Northern Virginia. The ATDM elements inside the vehicle allowed drivers to remain consistently aware of traffic conditions and roadway requirements even if external signage was inaccessible.

Forty participants were accompanied by a member of the research team and experienced the following in-vehicle device (IVD) features: 1) dynamic speed limits, 2) dynamic lane use/shoulder control, 3) High Occupancy Vehicle (HOV) restrictions, and 4) variable message signs (VMS). This ATDM system was equipped with auditory and visual alerts to notify the driver when relevant information was updated. The research questions addressed distraction, desirability, and driver behavior associated with the system. Participant data was collected from the instrumented vehicle, various surveys, and researcher observation.

Several key findings were uncovered related to each research category: 1) the IVD would not be classified as a distraction according to the National Highway Traffic Safety Association (NHTSA) distraction guidelines, 2) 73% of participants would want the in-vehicle technology in their next vehicle, and 3) the speed limit alert motivated participants to alter their speed (based on both survey results and actual participant speed data).

Kayla Sykes was honored at the Council of University Transportation Centers (CUTC) 2015 Annual Awards Banquet on January 9, 2016. For the past 24 years, the U.S. Department of Transportation (USDOT) has honored an outstanding student from each UTC at this special ceremony held during the Transportation Research Board (TRB) Annual Meeting. This year, students were recognized during the ceremony by the Assistant Secretary of Transportation for Research and Technology, Greg Winfree, and CUTC President, Joel Volinski. During the banquet, U.S. Secretary of Transportation Anthony Foxx gave the keynote address and Norman Mineta, former U.S. Secretary of Transportation, and Edd Hauser, director of the Center for Transportation Policy Studies at University of North Carolina-Charlotte, were honored with Lifetime Achievement Awards.

Kayla was selected for the 2015 Outstanding Student of the Year Award from the CVI-UTC for her outstanding academic performance and excellence in research. Kayla is a Graduate Research Assistant for the Virginia Tech Transportation Institute (VTTI). She completed her graduate coursework for her Master’s Degree in Civil Engineering from Virginia Tech in Fall 2015. Kayla has presented several posters related to her research with VTTI at both the Undergraduate Research Symposium and the Civil Engineering Research Day at Virginia Tech. Kayla also presented a poster regarding her CVI-UTC project and Master’s research at the 9th Annual UTC Spotlight Conference on Connected and Automated Vehicles on November 4, 2015.

Kayla’s Master’s thesis focuses on a human factors analysis of an in-vehicle Active Traffic and Demand Management (ATDM) system. She worked closely with VTTI employees to create an in-vehicle device that provides the following information to the driver: 1) dynamic speed limits, 2) dynamic lane use/shoulder control, 3) High Occupancy Vehicle (HOV) restrictions, and 4) other traveler information through variable message signs (VMS). The study’s research questions address driver distraction, desirability, and driver behavior while using the in-vehicle system in various traffic conditions. The results of this study will add to the body of knowledge for the effectiveness of in-vehicle signage and ATDM features.

Kayla has accepted employment with Toxcel following graduation and plans to continue to focus on improving transportation through human factors research and implementation.
