Lane separation method using eye-gaze guiding posts and eye guidance sign post

摘要

PROBLEM TO BE SOLVED: To provide a traffic lane separation method, using a delineator sign pole, that can improve visibility of a suppression bar and improve adjacent-lane-entry suppression effect even when a driver is at a long separation distance from the delineator sign pole, and the delineator sign pole.SOLUTION: In a lane separation method of performing lane separation by installing a plurality of delineator sign poles 1, each having a suppression bar 13 formed at an upper part of a sign pole body to project to one or both sides in a lateral direction, at intervals along a travel direction of a road, respective suppression bars 13 of the delineator sign poles 1 are protruded obliquely to a direction parallel with the travel direction of the road to face the travel direction. Each suppression bar 13 has a base part 131 which is formed as a different body from the sign pole body and fitted to an upper end part of the sign pole body, and a bar part 132 protruded from the base part 131, and the base part 131 is provided to rotate around the axis of the sign pole body and to be fixed at a predetermined rotational angel &thetas;.
