I found a great module for Joomla ...
http://extensions.joomla.org/component/option,com_mtree/task,viewlink/link_id,5734/Itemid,35/

But why is there not a script for PHP?
I gotta keep looking ... there must be one.

EDIT:
Getting Closer ...
See Google API - GDirections
(towards the bottom of the page, directions by walking or by driving).

The Joomla extension is just a PHP script ;)

I know that google can manage a route between 2 points. But I need to do between 30-60 points. The docs seem to imply that its possible but theres no working example of it - I'll have to fiddle with it and see what I can come up with.

Nancy ...

Maybe you can create a simple text file with the routes ...

Like this -- 2 destination pairs separated by pipe "|"

123 Elm St., St. Paul, Minnesota|334 Oak Ave., St. Paul, Minnesota
334 Oak Ave., St. Paul, Minnesota|5234 Summit Ave., St. Paul, Minnesota

etc.

Then, with PHP, loop through, generating a route from one to the other ... etc.

Like Point A to Point B, Point B to Point C, Point C to Point D ... etc.

I do notice that sometimes Google picks main routes, not the shortest route.

EDIT:
Nancy ...
Here you go ... PHP/MySQL bus route script:
