The automated passenger counting system market is poised for significant growth, projected to expand from US$5.14 billion in 2024 to US$9.1 billion by 2031, with a CAGR of 8.5% during this period. This growth is primarily driven by the increasing demand for accurate passenger data in public transportation, which aids in optimizing routes, schedules, and fleet management. The integration of AI, IoT, and machine learning is enhancing the accuracy and efficiency of these systems, further propelling market expansion. Display systems are expected to capture a significant share of the market, while infrared technology currently leads with a 40% market share. Regulatory mandates and funding for public transportation modernization, especially in North America and Europe, are also key factors driving the adoption of automated passenger counting systems. Major players such as Iris-GmbH, Infodev EDI, and DILAX Intelcom GmbH are leading the market with innovative solutions.
