Identifying and Labeling Potentially Risky Driving: A Multistage Process Using Real-World Driving Data

Figure 1

Converting TP data to MP data—using a vehicle moving at a constant velocity as an example. The red diamonds represent TP observations and the blue and green rectangles represent MP observations. Each MP observation contains 30 TP observations and a new MP observation begins every 10 TP observations. Of importance, it is to be noted that there is an overlap in each MP. The fourth, fifth, and sixth monitoring periods are colored green in order to improve visual readability of the figure—the color distinction does not hold further meaning.
