Actually, because a PRT system will have a large number of small vehicles, rather than a relatively small number of large vehicles, the chance of an individual becoming involved in a failure will reduce in proportion to vehicle size if the reliability of each vehicle is the same. But, because of the use of checked redundancy and advanced failure-management strategies possible within the confines of a PRT system, and the benign environment within the guideway, the reliability of it will be substantially higher than a conventional transit system. It has been shown that the requirements for dependability in a PRT system are independent of system size.
