Passenger traffic refers to the movement of people traveling from one location to another, typically using various modes of transportation such as airplanes, trains, buses, and cars. It is a key indicator of the demand for travel services and can be influenced by factors like economic conditions, tourism trends, and seasonal variations. Monitoring passenger traffic helps transportation companies and governments plan and manage infrastructure, ensuring that there are enough resources to accommodate travelers. This data is crucial for improving safety, efficiency, and overall travel experience, as well as for making informed decisions about future transportation projects.
