congestieaanduiding

Congestieaanduiding is a term used to describe the practice of communicating current and anticipated road congestion to road users. In Dutch traffic management, it refers to systems and procedures that provide travelers with timely information to help distribute traffic and improve network performance.

It relies on data from road sensors, cameras, and traffic models, which are combined with historical patterns to produce forecasts. The information is distributed via dynamic message signs, in-vehicle navigation, mobile apps, and radio traffic updates. Content typically includes estimated travel times, current speeds, queue lengths, and suggested alternatives.

Signage and interfaces often use concise messages and color codes to indicate congestion levels. In addition to signs, congestion indications can include speed advisories or ramp metering instructions and may be integrated with broader dynamic traffic management centers that coordinate incidents, roadworks, and weather effects.

The goals are to reduce peak-period congestion, spread demand more evenly, improve travel reliability, and increase safety by avoiding abrupt speed changes and bottlenecks. Congestieaanduiding also supports informed route choice for commuters and freight operators.

Challenges include ensuring accuracy and timeliness of information, preventing overload of drivers with too much data, and maintaining public trust in the guidance. Effectiveness depends on integration with other mobility services and on user acceptance of recommended routes or speeds.
