Road signage is a pivotal tool for helping people find their way on roads and is among the most efficient and least costly forms of communication for Destination Management (DM) i.e. the management of visitor flows to a specific destination.

In order for signage to play its intended role, it is essential to understand the territory and appraise its characteristics. A local project has to be designed around the people who populate it or flow to it: rationalising information for road users, smoothing traffic flows, providing traffic information, separating and directing local traffic away from heavy traffic, or making driving easier at intersections or on linear routes are a few examples of essential wayfinding interventions by local authorities and agencies. However, it is worth noting that promoting the potential of visitor flow management implies paying the utmost attention to the aesthetic characteristics, and to the materials and finishes of all signs and accessories chosen, the value of which cannot risk debasing the architectural value of a monument, the magnificence of a natural site, or the historical and cultural importance of a place.
