2.6Example figures for VSL / LC signs used for roadworks#

Typical arrangement figures which illustrate the application of variable speed limit and lane control signals to various work site situations are shown in Section 2.5 of this chapter. These figures indicate a nominal spacing of 750 m; however, the spacing between gantries may be larger or smaller depending on road geometry. Work site situations which are not specifically covered by the figures should be signed by adopting the most appropriate figure according to the principles outlined in this chapter.
