Feasibility Study of ITS Drifting-Out-of-Lane Alert System

摘要

This investigation looked at the feasibility of using either radio frequency (RF)or infrared (IR) technology to detect roadway boundary lines. Relatively low-cost electronics were designed to sense suitable paint stripes as illustrated using either reflected IR radiation (passive sensors) or using metal-detection technology to find paint stripes that were doped with iron fillings. Results indicate that both technologies work to some extent by that further refinement is necessary, and important issues remain to be addressed. Two RF technologies based on metal detection techniques were tested. Both used transmitting and detecting electromagnetic coils to probe the magnetic characteristics of the environment, but they differ in the type of signals used to excite the transmitter coil, and also differ in the signal characteristics observed by the detector. An application of this technology to automatically assist paint stripe replacement is suggested.
