färdvägvisning

Färdvägvisning describes the information provided to road users to guide them along a recommended route to a destination, or the next step in a journey. It is a core function of traffic information and intelligent transport systems. Färdvägvisning can be delivered through static signs as well as dynamic displays that adapt to current conditions.

Static elements include road signs showing destinations, arrows, and distances. Dynamic elements include variable message signs (VMS) and overhead gantries that can change content in real time. In addition, in-vehicle navigation devices and smartphone apps provide personalized route instructions synchronized with roadside information from centralized traffic management systems.

The purpose is to guide drivers efficiently, reduce congestion, and improve safety, especially during incidents, road works, or heavy traffic. Implementation is coordinated by national authorities and follows standardized guidelines. In Sweden, for example, major-road operations are overseen by Trafikverket, with the system designed to integrate signs, digital displays, and mobile applications. Effective färdvägvisning requires legible signs, adequate lead times, and consideration of driver behavior and information overload.
