While autonomous personal vehicles seem to be in the news nearly every day in one form or another, less has been publicized about the rise of autonomous transit. One new experiment, Autonomous Rail Transit (ART), will be appearing in Zhuzhou, China in 2018.
ART is a mixture of train, bus, and tram. ART does not require fixed infrastructure, but does follow specially painted lines on pavement, so it’s a hybrid between fixed rail and an open ended autonomous environment that is harder to control but easier to adapt. Having the ability to follow a track of painted lines opens the options to allow ART on any paved street relatively quickly and predictably and no new infrastructure would be necessary. It can be quickly materialized in cities that are willing to re-draw the lines on streets; potentially providing the flexible option that cities need for public transit to compete with personal vehicles. ART is a cheap way to move a lot of people, it’s the size of a small train but costs about as much as a bus, which is why cities favoring public transit are drawn to efficient and cost-effective solutions such as ART. Routes could be easily and inexpensively redrawn to adjust to behavior, or increased ridership, or land use changes, or just to tweak the system appropriately. Public transit is critiqued as being slow to implement, slow to change, and expensive. ART, by comparison, is none of these things.
Will the future of autonomous transit be a combination of fixed lines, semi-fixed routes like ART, and fully flexible neighborhood micro-transit?
