The experiment was carried out by the automation and robotics center of the Spanish Council of Advanced Scientific Research (CSIC). The GPS sensors allow, for instance, that if one bus detects traffic, it can then send this information to the central communication system.
Then management can decide to send a message out to other buses with the same affected stops to see if they can avoid this particular stretch of road or warn passengers that they may want to alter their commute for just one day. Likewise, once an ambulance moves or an accident is cleared up, a signal can be sent that the route has re-opened.
