Section 37.133 Subscription Service

As part of its paratransit service, an entity may include a subscription service component. However, at any given time of day, this component may not absorb more than 50 percent of available capacity on the total system. For example, if, at 8 a.m., the system can provide 400 trips, no more than 200 of these can be subscription trips.

The one exception to this rule would occur in a situation in which there is excess non-subscription capacity available. For example, if over a long enough period of time to establish a pattern, there were only 150 non-subscription trips requested at 8 a.m., the provider could begin to provide 250 subscription trips at that time. Subsequently, if non-subscription demand increased over a period of time, such that the 50 trips were needed to satisfy a regular non-subscription demand at that time, and overall system capacity had not increased, the 50 trips would have to be returned to the non-subscription category. During times of high subscription demand, entities could use the trip time negotiation discretion of §37.131(c)(2) to shift some trips to other times.

Because subscription service is a limited subcomponent of paratransit service, the rule permits restrictions to be imposed on its use that could not be imposed elsewhere. There may be a waiting list for provision of subscription service or the use of other capacity constraints. Also, there may be restrictions or priorities based on trip purpose. For example, subscription service under peak work trip times could be limited to work trips. We emphasize that these limitations apply only to subscription service. It is acceptable for a provider to put a person on a waiting list for access to subscription service at 8 a.m. for work trips; the same person could not be wait-listed for access to paratransit service in general.
