GPStrafikk

GPStrafikk is a traffic management and information platform used by road authorities to monitor, analyze and influence vehicular flow in real time. It aggregates data from roadside sensors, CCTV, weather feeds and user reports to create a common view of current conditions and to support incident response, traveler information and traffic optimization. The system is designed for interoperability with other ITS components and public information channels.

GPStrafikk emerged from intelligence transportation system initiatives in the late 2000s and was designed to replace fragmented data silos with an integrated platform. Early deployments focused on urban corridors, with regional and national expansion following as standards and data feeds matured.

The architecture comprises data collection, traffic state estimation and dissemination layers. Data sources include sensors, cameras, GPS probes and weather services, with results distributed through traveler information portals, dynamic signs and APIs for operators. GPStrafikk supports standards such as DATEX II and GTFS-RealTime to facilitate cross-system exchange and open data sharing, while applying privacy controls.

Operations are typically centralized in traffic management centers with 24/7 coverage. Staff coordinate incident handling, congestion management and lane use, in collaboration with police, emergency services and weather authorities. Governance generally involves national or regional transport authorities and formal data policies.

In regions with dense sensor networks, GPStrafikk can reduce travel times, shorten incident durations and improve public-facing traveler information. Limitations include gaps in rural coverage, data latency, and varying data quality, which ongoing upgrades aim to mitigate.
