    Behavioral Measures for 48 Participants in Work-Zone Messaging Driving Simulation Study collected in 2016 at the University of Minnesota
    (2018-04-18) Craig, Curtis, M; Morris, Nichole L; nlmorris@umn.edu; Morris, Nichole, L; University of Minnesota HumanFIRST Lab
    This study explored the impact of in-vehicle messages to alert drivers to events within a simulated work zone. Participants used a partial motion-based driving simulator made by Realtime Technologies, Inc. Data variables include speed, speed deviation, lane standard deviation, and eye-tracking fixation counts. The data is provided here for reasons of transparency and verification.

    Simulated driver performance, error, and acceptance study of a J-turn intersection with 3 levels of signage
    (2024-01-08) Morris, Nichole L; Schwieters, Katelyn R; Tian, Disi; Craig, Curtis M; nlmorris@umn.edu; Morris, Nichole L; University of Minnesota HumanFIRST Lab
    Thirty-six participants with limited previous experience and knowledge of J-turn intersections participated in a simulation study to examine their acceptance of J-turns and left turning navigational performance at three simulated J-turn intersections in counterbalanced order, each featuring one of three signage levels (minimum, intermediate, and full). Participants navigational path was visualized and scored for error occurrence by 3 raters/coders. Eleven different error types occurred and they were classified as minor, moderate, or major severity errors. Participants provided demographic information, crash history, and acceptance of J-turn intersections (across three scales) before and after driving through the simulated J-turn intersections. The data has been deidentified and is available to provide a better understanding of common errors from drivers who are experiencing J-turn intersections for the first time and the resultant influence that their error experiences have on their acceptance of the novel intersection design.

    Sound Localization Data of 29 Participants in Bicycle Alarm Development Study collected in 2018 at the University of Minnesota
    (2020-02-26) Morris, Nichole L; Craig, Curtis M; nlmorris@umn.edu; Morris, Nichole L; University of Minnesota HumanFIRST Lab
    This data file represents de-identified raw data from a sound localization experiment with 29 participants. Participants heard an experimental sound (Sound A.wav) or a car horn sound (vehicle045.wav) and had to indicate which direction of the sound. Also included are the sound files used in the study.
