Delays, congestion, or security-related incidents have an immediate impact on operations, safety and the entire transport network. AI video analysis for transport infrastructure provides the necessary transparency in real time: it analyzes movement flows, detects critical situations early and enables targeted control of security and operational processes before disruptions escalate.
