Masdar opens its first PRT, as shown in this CNN report hosted on the prtconsulting.com website. Alas the report says the system is being "scaled down". (I would have been curious to see this thing scaled up, and whether cars that work in isolation still work in a more complex environment).
Nevertheless, it is interesting how PRT and autonomous vehicles are now almost the same thing. It looks like we have transportation convergence between cars and transit.
