PRT Benefits
PRT systems usually operate on guideways, which can be on the ground, elevated or underground in tunnels. Some vehicles (Transportation Pods - or T-Pods) run on top of the guideways, while others are suspended from the guideways (this can make switching from one guideway to another more complicated).
Some systems follow magnets or wires buried in the guideway. Some use on-board navigation systems backed up by sensors that confirm the T-Pod position relative to objects along the guideway. Yet others are physically constrained by wheels that follow guideway walls or other vertical elements.
This variety of system characteristics enables some PRT systems to be more suited to a particular application than others. It can also complicate the process of choosing the best system for a specific use.
