The City Council of Bydgoszcz in Poland made a decision to support public safety system adding Fleet Vehicles Navigation module based on distributed real-time GPS data. Multi user GPS real-time emergency car positioning is realized over the Internet.
Vehicles are equipped with GPS/GSM unit and a client-server system passes GPS position data from the vehicles to the Command Center. In addition to position messages, vehicle alarm status and text messages can be sent between in order to control and supervise the operation. Moreover, areas on the GIS map can be defined as alarm zones and if a vehicle enters such an area, an alarm will be generated and followed on the map and all positions are recorded. In this condition, the red alarm label appears, an alarm signal is generated and the vehicle is zoomed.
