Uitwijkroutes

Uitwijkroutes is a set of predefined alternative routes within a transportnetwerk that can be activated when the usual routes are unavailable due to incidents, maintenance, of emergencies. They are designed to maintain mobility, distribute traffic more evenly, and increase the resilience of the network, reducing the risk of widespread congestion.

They are used in road, rail, maritime, and sometimes air transport, and are managed by national or regional authorities and traffic management centers. In road networks, uitwijkroutes are typically detour routes signposted with temporary signs and electronic message boards; in rail, diversion routes may reroute trains via alternate tracks or adjusted timetables; in ports or waterways, detours can circumvent affected channels.

Activation is triggered by incidents, planned works, of extreme weather; decision-making involves monitoring capacity and travel times and communicating with operators, authorities, and the traveling public. Information about active detours is disseminated through road signs, dynamic messaging, websites, apps, and media.

Design considerations include capacity, expected travel times, impact on adjacent corridors, and the ability to accommodate peak demand. Routes are planned to minimize backtracking and ensure safe maneuvering of traffic; signs are standardized to avoid confusion; maintenance ensures signs remain legible.

Limitations include longer travel times on detours, driver unfamiliarity, and potential secondary congestion; thus, performance is evaluated after activation to improve future responses. Uitwijkroutes are a core element of transport resilience and contingency planning.
