Travel systems refer to the organized methods and infrastructure that facilitate the movement of people and goods from one location to another. This includes various modes of transportation such as cars, buses, trains, and airplanes, as well as the networks that support them, like roads, railways, and airports. These systems are designed to improve efficiency, safety, and accessibility in travel. They often involve scheduling, ticketing, and route planning to ensure smooth operations. Additionally, travel systems can be enhanced by technology, such as GPS and mobile apps, which help users navigate and plan their journeys effectively.
