A data system for provisioning transit stops in a transit system is such that each transit stop has its own unique identity. The data system includes a central computer, at least a microprocessor at each transit stop, first communication means at each transit stop, second communication means on each transit vehicle, a security activator at each transit stop and annunciator means at each transit stop to provide visual and/or audible announcements. The central computer analyses the present location or driving condition data for any specific transit vehicle, and transmits data to a specific transit stop concerning the then estimated arrival time of a specific transit vehicle at that specific transit stop, at any instant in time, in real time. The central computer is adapted to receive a signal indicating an emergency situation at any specific transit stop at any instant in time, and to notify public authorities of that emergency situation.
