===Regulatory concerns===
Possible regulatory concerns include emergency safety, headways, and accessibility for the disabled. Many jurisdictions regulate PRT systems as if they were trains. At least one successful prototype, CVS, failed deployment because it could not obtain permits from regulators.<ref>See the references in [[Computer-controlled Vehicle System]]</ref>

Several PRT systems have been proposed for [[California]],<ref>See [http://www.santacruzprt.com/ www.santacruzprt.com] {{Webarchive|url=https://web.archive.org/web/20110208110916/http://santacruzprt.com/ |date=2011-02-08 }}.</ref><ref>[[Skytran]] was proposed for [[Orange County, California]], by its inventor, Maliwicki, who lives in that area</ref> but the [[California Public Utilities Commission]] (CPUC) states that its rail regulations apply to PRT, and these require railway-sized headways.<ref name="cpuc.ca.gov">{{cite web|url=http://www.cpuc.ca.gov/PUC/documents/go.htm|title=We're so sorry, your page was Not Found!|url-status=dead|archive-url=https://web.archive.org/web/20091231144823/http://www.cpuc.ca.gov/PUC/documents/go.htm|archive-date=2009-12-31}}</ref> The degree to which CPUC would hold PRT to "light rail" and "rail fixed guideway" safety standards is not clear because it can grant particular exemptions and revise regulations.<ref>California General Order 164-D, ibid. Sections 1.3,1.4</ref>

Other forms of automated transit have been approved for use in California, notably the Airtrain system at [[San Francisco International Airport|SFO]]. CPUC decided not to require compliance with General Order 143-B (for light rail) since Airtrain has no on-board operators. They did require compliance with General Order 164-D which mandates a safety and security plan, as well as periodic on-site visits by an oversight committee.<ref>{{cite web|url=http://docs.cpuc.ca.gov/published/Agenda_decision/22480-07.htm|title=Walker Agenda Dec - Order Concluding that Commission has Safety Jurisdiction Over SFO AirTrain}}</ref>

If safety or access considerations require the addition of walkways, ladders, platforms or other emergency/disabled access to or egress from PRT guideways, the size of the guideway may be increased. This may impact the feasibility of a PRT system, though the degree of impact would depend on both the PRT design and the municipality.
