That would not be possible with this map. Looks like you need an app, or just an open web page, that the bus driver has to keep updating his position, and a map page that periodically updates to show the last known location for all buses and their routes. Would need a custom app for that.
All you did was upload the .tar file you downloaded from the marketplace, right? Are you able to install other apps? Have you verified the directory permissions as stated in the error?
