Definitions

  • the present invention refers to a method for improving the traffic of emergency vehicles, in which the emergency vehicles using this method on the road network have a terminal with access to a wireless network (for example, the mobile phone network). Knowing the position of the emergency vehicle by means of the beacons placed on different spots of the road network, the network informs the rest of the vehicles in the road network, provided they are within short distance from the emergency vehicle of the security parameters (such as maximum speed allowed, safe distance from the preceding vehicle) and other requirements which must be fulfilled in order to facilitate the movement of said emergency vehicle, minimising accident risks.
  • the security parameters such as maximum speed allowed, safe distance from the preceding vehicle
  • the method object of the invention solves the hereby stated problem by informing the drivers for them to clear the roads for the emergency vehicles and therefore reducing the time it takes for them to reach their destination, plus increasing safety, especially at crossroads.
  • the present invention refers to a method for improving the traffic of emergency vehicles through the use of beacons, according to claim 1 and claim 6, in its two alternative solutions. Preferred embodiments of said method are defined in the dependent claims.
  • PATSEMB Traffic Accident Prevention for Emergency Services using Beacons
  • the method described in claim 1 comprises the following stages for each vehicle subscribed to the PATSEMB service:
  • the emergency vehicle subscribed to the PATSEMB service can end its subscription to said service when said emergency vehicle does not contact the network in a predetermined time, T EXP , or when said emergency vehicle sends the network a request to end the subscription to the PATSEMB service.
  • the TE of the emergency vehicle can send the network the PATSEMB service identifier and the IDVE TEMP temporary identifier belonging to said terminal; the network will later verify that the validity of said IDVE TEMP has not expired.
  • Emergency vehicles subscribe to the PATSEMB service if they wish the other vehicles to be informed about their presence.
  • the vehicles which participate in the PATSEMB service are those connected to the wireless access network, through a terminal in each vehicle, and can receive information from the PATSEMB service warning them about the presence of an emergency vehicle.
  • Those vehicles which do not have a terminal to access the wireless access network do not participate in the PATSEMB service; therefore, they cannot receive messages from the wireless access network.
  • Those vehicles which do not take part in the PATSEMB service may be informed by means of information signs controlled by the PATSEMB service itself and located at troubled spots of the road network (for example in those areas in which the beacons are placed).
  • the PATSEMB service obtains the corresponding permission, traffic lights and other traffic signs could be controlled, in order to warn all surrounding vehicles of the presence of an emergency vehicle.
  • the TE belonging to the emergency vehicle sends out a request to the wireless access network to subscribe to the PATSEMB service, and along with that request, it sends the PATSEMB service identifier being requested, a single ID VE identifier for the emergency vehicle and optionally, a password IDVE PASS to have access to the service for that ID VE -
  • the wireless access network verifies the validity of the TE subscription and sends to the TE of the emergency vehicle a temporary IDVE TEMP identifier.
  • the TE is set to listening mode to receive information of the positioning beacons in the communication channel used by said beacon to communicate with the emergency vehicles using the PATSEMB service.
  • the TE verifies, after receiving a message sent by a positioning beacon, that the service provided by said beacon corresponds to the PATSEMB service, in which case each time it receives a message from a beacon, and if considered necessary, the TE sends to the positioning beacon its IDVE TEMP identifier and optionally, the ID B identifier thereof. Every time the beacon receives such information from the emergency vehicle, said beacon sends to the wireless access network the IDVE TEMP identifier, and its ID B identifier.
  • the wireless access network informs a plurality of vehicles from the rest of the vehicles moving along the road network about the presence of an emergency vehicle near that beacon.
  • the procedure the wireless access network follows to inform the rest of the vehicles about the presence of the emergency vehicle is identical to the one previously described.
  • the procedure to end the subscription to the service and to ask for a new subscription is also identical to the one described in the first method.
  • the method object of this invention is based on the availability in emergency vehicle 1 of a TE 3 which is used by the driver of said vehicle 1; TE 3 has a client application installed.
  • the method uses positioning beacons 6 fixed to the rails and/or mobile beacons 6 (being the latter usually equipped with means to determine their position) which use any kind of wireless technology, usually short-range such as RFID.
  • Beacons 6 broadcast within their reach, in diffusion mode, or they can be activated by means of a vehicle sensor so that their ID B identifier and the ID PATSEMB service identifier provided are not continuously broadcasting.
  • the procedures used to implement it are the following:
  • the information sent to said vehicles will depend on where they are located:
  • the parameters the network will send in the step subscription P1 will be the PATSEMB service identifier and the temporary identifier IDVE TEMP of the emergency vehicle 1.
  • the network will verify that said IDVE TEMP has not expired and therefore, access to the service is guaranteed.
