What grade do you teach? I teach 5th grade, so mostly the students already know what to do. For younger students, you might try use a bulletin board with the transportation options and then each morning during the morning routines have the students place their name card under the transportation they will use at dismissal. If you have a SmartBoard or other interactive whiteboard, you can make a notebook file that will do the same thing.
End-of-the-day routines can work seamlessly with end-of-activity summations and assignments throughout the day.
For example, a colleague taught me to have each student keep a special folder into which assignment instructions, permission slips, etc., were placed. At the end of the day, the folder contents undergo a quick review before going home while the folder remains at school.
By accruing tasks and projects in a guided, orderly fashion, students learn self-management skills and gain a sense of controlling their assignments rather than feeling overwhelmed by them. It is useful to remind them in appropriate language that, as they leave school, they become self-directed, independent learners. This approach can help empower them to approach tasks with confidence and energy--well, maybe in a perfect world!
In this context, transportation (for example) becomes a trivial task they can check off their list before going on to greater challenges.
