An efficient approach to lane tracking system vehicular telemetics

To measure a vehiclepsilas lateral position relative to the lane of the road a low cost system can be developed to measure it. While operating the system during day and night it has the capability to track white or orange lines, solid or dashed edge lines. The system is comprised of two ldquooff the shelf ldquoblack and white charge coupled devices (CCD) video cameras along with commonly available electronic components. The lane system is capable of outputting real time data at 30 Hz through an analog output. Using the data from this sensor system it is possible to detect the lane changes, determines the magnitude, duration of lane exceedance and other metrics used by researchers in transportation community. This paper will discuss the design and performance of the system, processing of raw lane trackers data, and benefits and limitations of the technology.
