Assessment of then Freeze probing and Real-time-probing Strategies for Situation Awareness Evaluation in Pedestrian Environments

Author(s): Mark Huang

 The surroundings has an impact on a pedestrian's safety. Because people walk often during the day, there is typically a reduction in pedestrian awareness. Situation Awareness (SA) tests can assess a pedestrian's capacity to respond to their surroundings. This is a reference to the significance of being aware of the SA of pedestrians using reliable measuring techniques. This study compares the freeze probing and real-time probing approaches to assess SA measurement methods based on how well they capture SA in a pedestrian environment. Eleven pedestrians (7 men) with an average age of 22 (SD 1.3) years and daily walking habits of 15 (SD 8.5) minutes participated in the study. A video of a person using a treadmill with three speed settings was shown to the participants. In several settings, SA was measured via frozen and real-time probing. Based on spoken procedure, performance was assessed. Real-time probing has more sensitivity but higher intrusiveness issues. This probe exhibits higher predictive outcomes in low workload situations, which is consistent with the features of the pedestrian domain, based on the regression results between predictors in the form of SA scores and performance as dependent variables. Real-time probing is thought to be more efficient for SA measurement demands in pedestrian contexts that are often straightforward, steady, and do not result in significant workloads due to its benefits. In order to improve the notion of SA and create new designs or procedures in the pedestrian environment, an effective assessment method must produce an accurate measure of SA score.
