Zusammenfassung:	The invention relates to a road boundary identification method and system. The method comprises the following steps: acquiring each static reflection point of a radar; obtaining a left boundary transverse position and a right boundary transverse position according to each static reflection point; screening out each left boundary point and each right boundary point from each static reflection point; whether the number of middle points is smaller than a first threshold value or not is judged, wherein the middle points are static reflection points located between the left boundary points and the right boundary points; if yes, a road left boundary curve and a road right boundary curve are obtained according to the left boundary points and the right boundary points; and if not, obtaining a road left boundary curve and a road right boundary curve according to each intermediate point. According to the road boundary recognition method and system, the curvature, the curvature change rate and the course angle of the bo
