On campus they wait at the main cafeteria, as well as at the bus stop by the pedestrian overpass opposite campus on Phuttamonthon 4 Road. In Pinklao they wait in Q8 Gas station close to Central Department Store.
Regular free shuttle buses for staff and students also commute between the Office of the President building and Bangkok in every half an hour from the early morning to late afternoon. For current scheduling details, please see the relevant webpage on http://www.mahidol.ac.th/en/shuttle_bus.html.
