My understanding is that these services vary from 'fixed route-variable times' through to completely random routes. Another question is if the services stop anywhere on the route or only at fixed points or possibly there are some fixed points and then anywhere on the route in addition. If there are fixed points then these can be added as stops. In the UK we have 'hail-and-ride' which are linear sections of route where the vehicle will stop which are treated like bus stops. We also have share taxi 'demand responsive' services and can defined 'flexible zones' as polygons where the service will pick people up from anywhere within the zone. These can then all treated as being 'bus stops'. It is still hard to describe the services themselves. Fixed routes can be added a bus routes (as in your example). If not then you may be more on your own! Here is a diagram and some modeling details from the UK schema if that helps. http://www.dft.gov.uk/transxchange/schema/2.0/examples/flexible/ I will be very interested to hear how you get on with this one.
