headways enough to be worthwhile, by automating the steering as well the operational costs can also be reduced compared to crewed vehicles.

One key problem in an automated system is the steering system's negotiation of turns in the right-of-way. The simplest solution is to use a rigid guideway, like conventional rails or steel rollercoasters. For lighter AGTs, these solutions were over-specified given the size of the vehicle, so the guideway was often separate from the running surface. Typical solutions
