DESIGN AND IMPLEMENTATION OF A SYSTEM TO RECORD DRIVER LATERAL POSITIONING

An important indicator of driving performance is steering or tracking accuracy. Previous attempts to measure this variable have suffered from a variety of limitations. Previous attempts are reviewed, and numerous criteria are specified for an optimal tracking-system design. These criteria are used to develop a novel photooptic system that mounts on a test vehicle and continuously records lateral lane positions. The device uses a photodiode array to detect the position of the vehicle relative to the pavement shoulder line. System design, data reduction procedures, and practical implementation considerations are discussed. System performance is demonstrated by recording driver tracking performance over shallow right and left curves. The system is sensitive to the differences in driving behavior on the 2 curves. The device is presented as a flexible, reliable, and accurate instrument for recording vehicular track.
