... DRT passengers are generally provided a seat, unlike fixed-route service where standees may increase vehicle capacity. ADA complementary paratransit regulations are given in 49 CFR Part 37, Subpart F
From page 439...
... Transit Capacity and Quality of Service Manual, 3'd Edition Non-ADA providers of DRT service do not have any federal requirements regarding capacity. Such providers may offer capacity according to local policy and funding levels, and may adopt service policies affecting capacity-for example, prioritizing limited capacity to serve specific trip purposes such as medical, school, and work.

... Transit Capacity and Quality of Service Manual, 3'd Edition • Trip pattern type-many-to-few, many-to-one and few-to-few DRT services can group passenger trips, achieving higher productivities and requiring fewer vehicles than a service that operates many-to-many; and • Service policies, such as the size of the on-time window-the shorter the window, the more the window constrains scheduling, with a resulting need for additional vehicles. Importantly, if the DRT service is an ADA paratransit program, the service must provide enough capacity to meet the demand.
