TRAFFIC SIGNING

Simply defined, yet although the signs around us play an essential part of our daily lives, they are often taken for granted.

As the first line of communication, the impact of a quality sign in today's image conscious world should not be underestimated.

CKG provides the complete service including Advice, Consultation, Site Investigations, Sign Inventories and Surveys, Detailed Design, Schedules Location Plans, manufacture and installation.

Clear and high quality signing can improve the Environment. By guiding the appropriate traffic along the correct routes,  may reduce congestion, thus reducing vehicular pollution. With modern approaches, consideration and materials, the design of the signs can be rationalised for the surrounding area/junction which in turn can reduce street clutter, obstructions, distractions and visual pollution. Certain direction and warning signs no longer require illumination, therefore eliminating light pollution.

Signing using the latest materials (may also be using in conjunction with road markings, traffic regulation orders etc) can influence: movement of traffic and types of traffic, average speed of traffic, reduce traffic conflict and in doing so, reducing the number of crashes and their severity.

Clear signing makes it easier for the user to read, which can reduce a drivers hesitation on the road, often a cause of collisions!!!

Good signing can save businesses money by reducing the amount of time that goods are lost by drivers looking for a specific destination or route.
