Abstract
A system, method and storage medium for providing an emergency vehicle alert includes first device transmitting EV data including a current location of an EV to a management server, management server receiving the EV data from the first device, the management server determining a geofence for the EV at least based on the received EV data and geographical map data near the EV, and management server transmitting the determined geofence to a second device. The first device is associated with the EV, and the second device is associated with the another vehicle.
Claims20
A system for providing an emergency vehicle (EV) alert, comprising:
- a first device associated with the EV, the first device configured to transmit EV data including a current location of the EV to a management server;
- and
- the management server configured to:
- receive the EV data from the first device;
- determine a geofence for the EV at least based on the received EV data and geographical map data near the EV;
- and
- transmit the determined geofence to a second device associated with another vehicle;
- wherein the management server comprises a processor, to determine the geofence, the processor is configured to:
- receive the geographical map data from a storage device;
- define at least one zone on a map rendered using the geographical map data;
- determine a zone, among the at least one zone, to which the current location of the EV belongs;
- and
- determine the geofence based on the determined zone on the map, and
- wherein the at least one zone comprises a first zone and a second zone separated along with a forward direction of the EV, and the first zone and the second zone are separately defined at least based on whether a road on which the EV travels has a median strip.
A system for providing an emergency vehicle (EV) alert, comprising:
- a first device associated with the EV, the first device configured to transmit EV data including a current location of the EV to a management server;
- and
- the management server configured to:
- receive the EV data from the first device;
- determine a geofence for the EV at least based on the received EV data and geographical map data near the EV;
- and
- transmit the determined geofence to a second device associated with another vehicle,
- wherein the management server comprises a processor, to determine the geofence, the processor is configured to:
- receive the geographical map data from a storage device;
- define at least one zone on a map rendered using the geographical map data;
- determine a zone, among the at least one zone, to which the current location of the EV belongs;
- and
- determine the geofence based on the determined zone on the map, and
- wherein the at least one zone comprises a first zone and a second zone, and the first zone and the second zone are separately defined at least based on whether there is at least one another road allowing a vehicle traffic flow into or from a road on which the EV travels.
A system for providing an emergency vehicle (EV) alert, comprising:
- a first device associated with the EV, the first device configured to transmit EV data including a current location of the EV to a management server;
- and
- the management server configured to:
- receive the EV data from the first device;
- determine a geofence for the EV at least based on the received EV data and geographical map data near the EV;
- and
- transmit the determined geofence to a second device associated with another vehicle,
- wherein the management server comprises a processor, to determine the geofence, the processor is configured to:
- receive the geographical map data from a storage device;
- define at least one zone on a map rendered using the geographical map data;
- determine a zone, among the at least one zone, to which the current location of the EV belongs;
- and
- determine the geofence based on the determined zone on the map, and
- wherein when the determined zone includes an underpass or overpass crossing a road over which the EV travels, the determined geofence is defined to exclude the underpass or overpass.
