Hello Harald,
Thanks for your suggestions
a)  I agree that using the same attribute name for two related but subtly
different things is adding unnecessary confusion (I fact, confusion was
recently observed).
Since the 'period' attribute of flows has a lot of history behind it I'll
keep this unchanged.
However, I renamed route attribute period to 'cycleTime' (see
https://github.com/eclipse/sumo/issues/7168).

b) Incidentally, I was thinking about the same thing recently and came up
with this: https://github.com/eclipse/sumo/issues/7164
For an example. see
https://github.com/eclipse/sumo/tree/master/tests/sumo/devices/rerouting/stops/public_transport_implicit_route

c) This is already working with the recent fix:
https://github.com/eclipse/sumo/tree/master/tests/sumo/devices/rerouting/stops/public_transport_implicit_route_depot


@Dillip Rout: I generally avoid adding new input definitions as long as the
existing ones can be used to achieve the desired results. Also, you may
find that there is good reason in keeping the edges/stop-list separate from
definition of the vehicles that run these stops (especially, when the
departure times of the vehicles are not spaced regularly over the whole
day).
In terms of changing ambiguous names, there is a large cost associated with
changing things that have been used by many people over many years. The
case of route attribute period / cycleTime is special insofar that the
feature was added recently and thus will not have been widely adopted yet.
This is not to dismiss thoughts on improvements but rather to point out
some of the constraints. Feel free to point out things that are confusing
and/or inefficient.

regards,
Jakob
