A subscription trip is a trip that is
regularly repeated between the same origin and destination and at the same time.
Subscription service is not a requirement of the ADA. ADA
Regulations 49 CFR, Part 37, Section 37.133 permit transit agencies to establish waiting
lists or other capacity controls and trip purpose restrictions (e.g., work trips only) or
priorities for participation in the subscription service. Subscription service may not
absorb more than fifty (50) percent of the number of trips available at a given time of
day, unless there is non-subscription capacity.
