HUB-to-HUB Journeys

Let us consider the case where the SH and DH are in the same region. The first thing to do is to have point-to-point bus routes between a given HUB and the HUBs relatively near that HUB. If, however, there are ten HUBS in a region we will have a large number of routes connecting each HUB with every other HUB in that region and it will be difficult to provide buses every five minutes on those routes. In such situations, we will choose one of the HUBS, somewhere in the middle of that region, as a SUPER HUB and connect it with all the HUBS within that region. This is somewhat like the simple theoretical model (Bus Hopping), where M is like a Super Hub. In some regions, it may be convenient to have more than one Super Hub.
