Development of in-vehicle system for evaluating the "quality of driving"

In this paper, we propose the concept of "QOD (quality of driving)". We have developed a real-time system, which measures the stability of driving condition and evaluates the "QOD". There are several items to measure the stability of driving condition. So, we selected the following three parameters: "the degree of meandering", "the rightness of the velocity", and "the sufficiency of the distance between the driver's own vehicle and the other vehicle ahead". In our experiment, we installed a CCD camera on the dashboard of our vehicle, and we obtained three parameters form the sequence of the image taken by the camera, and evaluated the "QOD".
