If you are a regular bus user, or if you have a connection with the CPTM (Metropolitan Transit Organization of São Paulo), you may have already used VouD.

VouD is the best way to plan your trip and be on time. It allows you to check when the transport will pass at the point or station of your choice, giving you the opportunity to plan to be there at the desired time, without having to waste time waiting for the transport. This is especially useful for people who work shifts and for whom the schedules are not published in advance.
