I was in hopes that you received input on your questions as I would also be interested in what others have tried. We have had several students with transportation issues.
One resourse that we do offer is circulating an "Exchange List" where students can sign up with their name, town they live in, email, and areas they would like to get together with other students. We are considering adding a checkbox for carpooling. Though I'm not sure of success as it hasn't been impletmented yet.
