The latter typically look at specifying operational aspects of service provision: on-time performance, availability of service, location of stops and even detailed schedule-based frequency. These are adapted to the type of services route-based bus and rail services provide but make little sense for platform-based ride services. Coverage of services, average wait times (and their distribution) for both regular services and for accessible services, for example, all focus more on the outcomes that ride services can contribute to and may be more relevant for contracting with the providers of ride services. Currently, most of the pilots looking at the delivery of ride services allocate risk to the public authority contracting the service.
