====Guideways====
Several types of guideways have been proposed or implemented, including beams similar to monorails, bridge-like [[truss]]es supporting internal tracks, and cables embedded in a roadway. Most designs put the vehicle on top of the track, which reduces visual intrusion and cost, as well as easing ground-level installation. An overhead track is necessarily higher, but may also be narrower.  Most designs use the guideway to distribute power and data communications, including to the vehicles. The [[Morgantown Personal Rapid Transit|Morgantown PRT]] failed its cost targets because of the steam-heated track required to keep the large channel guideway free of frequent snow and ice. Heating uses up to four times as much as energy as that used to propel the vehicles.<ref>{{cite web |title=The History of my Involvement in PRT and how it led to ATRA |url=https://www.inist.org/library/2019-10.Anderson.History%20of%20my%20involvement%20in%20PRT%20led%20to%20ATRA.pdf |website=INIST |access-date=3 July 2021 |archive-date=9 July 2021 |archive-url=https://web.archive.org/web/20210709185013/https://www.inist.org/library/2019-10.Anderson.History%20of%20my%20involvement%20in%20PRT%20led%20to%20ATRA.pdf |url-status=dead }}</ref>  Most proposals plan to resist snow and ice in ways that should be less expensive. The Heathrow system has a special de-icing vehicle. Masdar's system has been limited because the exclusive right-of-way for the PRT was gained by running the vehicles in an undercroft at ground-level while building an elevated "street level" between all the buildings.  This led to unrealistically expensive buildings and roads.<ref name="whymasdarscaleback"/>

====Stations====
Proposals usually have stations close together, and located on side tracks so that through traffic can bypass vehicles picking up or dropping off passengers. Each station might have multiple berths, with perhaps one-third of the vehicles in a system being stored at stations waiting for passengers. Stations are envisioned to be minimalistic, without facilities such as rest rooms. For elevated stations, an elevator may be required for accessibility.

At least one system, Metrino, provides wheelchair and freight access by using a cogway in the track, so that the vehicle itself can go from a street-level stop to an overhead track.

Some designs have included substantial extra expense for the track needed to decelerate to and accelerate from stations. In at least one system, Aramis, this nearly doubled the width and cost of the required right-of-way and caused the nonstop passenger delivery concept to be abandoned. Other designs have schemes to reduce this cost, for example merging vertically to reduce the footprint.
