A new marker device (100) is provided for increased safety due to a flexible design. The marker device (100) includes a base (110) and a flexible means (142) that is positioned over the base (110). The bottom part (140) of the flexible means is attached to the base (110). The flexible means (142) maintains in an original position in absence of a natural or traffic perturbation. However, flexible means (142) deviates from this original position in presence of a natural or traffic perturbation. Moreover, the flexible means (142) restores from this deviated position back to the original position after the perturbation disappears or is removed. Furthermore, the marker device (1001) includes a cover (130) to cover the flexible means (142). |
