Abstract: Lane Departure Warning System (LDWS) is advanced technology used now days and developed for assisting the driver. The main purpose is to detect the lanes and warn the driver for lane departure. Various techniques are available for detection of lanes. This paper describes different lane detection methods. The most effective technique is FPGA based Hough transform which shows reduced logic area and optimum memory utilization.

Keywords: Lane departure warning systems, Lane keeping, Lane detection, Hough transform.
