Final answer:
Real time location systems are typically used by rail carriers, which operate on fixed routes, to optimize operations and safety. Although other transportation methods like motor, air, and water carriers could use RTLS, the rail industry's structured nature makes it a prime candidate for real-time tracking.
Step-by-step explanation:
Real time location systems (RTLS) are technology solutions that track the location of assets or people in real-time, typically within a defined space like a building or a campus. RTLS can be applied to different types of transportation for various purposes, such as asset tracking, inventory management, and improving operational efficiency. However, the question asks which type of transportation uses RTLS.
While RTLS could theoretically be applied to any transportation sector, the information provided suggests a focus on transportation systems that are not battery-reliant and use prescribed routes. With this in mind, RTLS is most commonly associated with rail carriers, as they operate on fixed tracks and can benefit from the precise tracking and management of their assets. Rail systems, such as light rail and high-speed trains, utilize electrification via overhead wires or third rails and are typically on fixed routes where RTLS can optimize operations and safety.
Motor carriers, air carriers, and water carriers could all use RTLS for asset and inventory tracking, but rail carriers' use of prescribed routes makes them a particularly suitable application for RTLS.
