Rutinginformasjonen

Rutinginformasjonen, or routing information, refers to the data, methods, and rules used to determine optimal paths for movement from one location to another. In transport planning, logistics, and consumer navigation, it covers the structure of the network (intersections, roads, and transit links) and the attributes used to evaluate routes, such as distance, travel time, speed limits, and mode restrictions. It also includes dynamic data that can change during a journey, such as traffic, incidents, and weather.

The information is drawn from multiple sources, including geographic information systems, road and transit networks, traffic sensors, incident feeds, and sometimes user-generated data. Quality depends on coverage, update frequency, accuracy, licensing, and the consistency of attributes across different parts of the network.

Routing information enables a range of applications: consumer navigation apps, public transit trip planners, logistics and fleet optimization, emergency response, and planning studies. It supports static planning (pre-trip routes) and real-time routing that adapts to current conditions.

Common formats and standards include GTFS for transit schedules, GTFS-rt for real-time updates, and OpenStreetMap for street networks, often used by routing engines and mapping platforms. Many systems expose routing information through APIs that allow developers to request routes, estimated times, and alternative paths.

Challenges in routing information include keeping data current, integrating multiple data sources, balancing speed and accuracy, and handling privacy and licensing considerations. Ongoing trends include multimodal routing, predictive traffic models, and deeper integration with autonomous and connected transportation systems.
