Editing Personal rapid transit (section)

====Propulsion====
All current designs (except for the human-powered [[Shweeb]]) are powered by [[electricity]]. In order to reduce vehicle weight, power is generally transmitted via lineside conductors although two of the operating systems use on-board batteries. According to the designer of Skyweb/Taxi2000, [[J. Edward Anderson]], the lightest system uses [[linear induction motor]] (LIM) on the vehicle for both propulsion and braking, which also makes manoeuvres consistent regardless of the weather, especially rain or snow. LIMs are used in a small number of rapid transit applications, but most designs use [[rotary motor]]s. Most such systems retain a small on-board battery to reach the next stop after a power failure.  CabinTaxi uses a LIM and was able to demonstrate 0.5 second headways on its test track.  The Vectus prototype system used continuous track mounted LIMs with the reaction plate on the vehicle, eliminating the active propulsion system (and power required) on the vehicle.

[[ULTra]] and 2getthere use on-board batteries, recharged at stations. This increases the safety, and reduces the complexity, cost and maintenance of the guideway. As a result, the ULTRa guideway resembles a sidewalk with curbs and is inexpensive to construct.  ULTRa and 2getthere vehicles resembles small automated electric cars, and use similar components.   (The ULTRa POD chassis and cabin have been used as the basis of a shared autonomous vehicle for running in mixed traffic.<ref>{{cite news |title=Westfield Technology Group autonomous POD confirmed for Fleet Live 2019 |url=https://www.fleetnews.co.uk/news/fleet-industry-news/2019/08/01/westfield-technology-group-autonomous-pod-confirmed-for-fleet-live-2019 |access-date=28 June 2021 |date=1 August 2019 |archive-date=28 June 2021 |archive-url=https://web.archive.org/web/20210628030728/https://www.fleetnews.co.uk/news/fleet-industry-news/2019/08/01/westfield-technology-group-autonomous-pod-confirmed-for-fleet-live-2019 |url-status=dead }}</ref>)
