Apologies for sending my reply to the list. Replying directly to Alex
resulted in an 'undeliverable'.
Alex, here's my reply:
I did a similar project on bus routes when working in local government
here in Sydney. If the bus routes are in separate tables, you could have
lines of different thicknesses, colours and styles. This would allow
you to overlay one route on top of another. If the routes are in the
same table, you could take the same approach with lines styles and
shapes by creating a thematic map of the routes. Either provides the
same visual result. Hope this helps.

Subject: MI-L Parallel Bus routes over a street map
Greetings List,
Does anyone have a solution for showing parallel bus routes on a map?
Bus routes are mapped along road sections - different routes in
different colors. The user wants to retain the geographic accuracy of
each route i.e. along the road centerline but be able to see visually
that there are a number of routes on one section. That means being able
to see the different route lines along the road.
Mapping out the lines parallel to the road does not retain geographical
accuracy and has visual drawbacks when one route is selected which is
displaced at a distance, beyond other routes that were mapped nearer
and are not now shown.
Having two map schemas, one for geographical accuracy and the other for
viewing raises major maintenance problems.
A third possibility could be writing a function which will dynamically
spread, for viewing purposes only, the different lines parallel to the
road section chosen.
Any ideas, experience or suggestions will be welcome.
TIA to all responders. Will summarize received advice.
Best regards,
Alex Eshed
