An example operation includes one or more of receiving, via a transport, a transport audio, classifying, via the transport, a subset of the transport audio as an atypical transport audio, determining, via the transport, a possible source location of the atypical transport audio, transmitting, via the transport, the atypical transport audio and the possible source location to a server, determining, via the server, a set of potential causes of the atypical transport audio and receiving, via the transport, the set of potential causes of the atypical transport audio.

The present invention relates to a communication system which can effectively avoid congestion in ITS communications at a street intersection to properly assist the driving of autonomous vehicles. An information source roadside apparatus 3 acquires terminal movement information on movement directions of nearby pedestrian terminals, and transmits the information to an information destination roadside apparatus, which determines, based on the received information, if there is predicted congestion in the terminal-to-terminal communications at a predetermined future time. When determining that there is predicted congestion, the information destination roadside apparatus transmits an instruction for a congestion avoidance operation to the pedestrian terminals 1. Then, each pedestrian terminal performs the congestion avoidance operation by switching a communication mode from a direct communication mode using the terminal-to-terminal communications, to an indirect communication mode using communications via a roadside apparatus.

A communication device includes a target locating unit configured to locate a position of a target having a risk of approaching a moving body. The communication device includes a transmission unit configured to transmit request information including positional information of an external terminal, for which the positional information is requested, based on the position of the target located by the target locating unit. The communication device includes a reception unit configured to receive response information with respect to the request information. The transmission unit is configured to transmit warning information based on the positional information of the external terminal included in the response information.

An alert control device including: a risk area identifying unit for identifying a risk area outside a mobile object based on operation information of the mobile object; a transmission control unit for controlling transmission of risk area information containing risk area location information outward the mobile object; a reception control unit for controlling reception of response information for the risk area information; and the output control unit for controlling output of alert information at least into the mobile object based on the response information. An alert controlling method including: identifying a risk area outside a mobile object based on operation information of the mobile object; controlling transmission of risk area information containing risk area location information outward the mobile object; controlling reception of response information for the risk area information; and controlling output of alert information at least into the mobile object based on the response information.

A control apparatus includes a risk area identification unit for identifying a risk area outside a movable object with respect to a movement of the movable object based on an image captured by an image capturing apparatus mounted on the movable object, and a transmission control unit for performing control to transmit risk area information including position information of the risk area, and precision information related to a calculation precision of the position information to an outside of the movable object without designating a destination, wherein the transmission control unit transmits the position information and the precision information to cause a terminal having received the position information and the precision information to determine whether a position thereof corresponds to an inside of the risk area, and cause an alert unit included in the terminal to output an alert when it is determined that the terminal is inside the risk area.

An alert control apparatus includes an obtaining unit configured to obtain recognition information including position information of each of a plurality of targets present outside a movable object, a risk level decision unit configured to decide a risk level for each of the plurality of targets to approach the movable object, a selection unit configured to select a plurality of targets corresponding to alert targets based on the risk level decided by the risk level decision unit, a classification unit configured to classify the plurality of targets selected by the selection unit into one or more groups based on the position information of each of the plurality of targets selected by the selection unit, and a transmission control unit configured to perform control to transmit alert information including position information of the one or more groups.

A control apparatus includes a risk area specification unit to specify a risk area outside a movable object, a transmission control unit to perform control to transmit alert information related to a position of the risk area to an outside of the movable object, a reception control unit to perform control to receive response information including information related to a position of another movable object that is response information to the alert information which is transmitted by the other movable object, and a control unit to execute control of the movable object based on position information of the risk area and the information related to the position of the other movable object which is acquired, in which the alert information includes information for controlling a mode related to a transmission cycle of the response information to be transmitted by the other movable object which has received the alert information.

One embodiment of the present invention relates to a method for a reader to transmit and receive a signal to and from a tag, the method comprising: a step in which a first reader transmits a first signal to a tag; and a step in which the first reader receives the first signal reflected on the tag. The timing for the first reader to transmit the first signal is determined by using an offset value based on an ID related to the first reader.

An example operation includes one or more of initially determining, via one or more sensors on a transport, that the transport is approaching a one-way road in a wrong direction based on a slowing down of the transport and a movement of the transport toward the one-way road, notifying, via the one or more sensors, one or more occupants of the transport about the approaching, and in response to the transport continuing to approach in the wrong direction, slowing the transport, by a computer associated with the transport, to not permit entry into the one-way road.

A method for providing a maneuver message for coordinating a maneuver between a road user and at least one further road user in a communication network. The method includes: receiving the communication data and/or the sensor data in the evaluation unit; determining a possible trajectory of the road user based on the communication data and/or the sensor data, at least one trajectory parameter describing a property of the possible trajectory being ascertained; calculating a trajectory transfer priority from the trajectory parameter, the trajectory transfer priority representing a relevance of the at least one possible trajectory for the road user and/or the further road user; determining, based on the trajectory transfer priority, whether the at least one possible trajectory is to be included in a maneuver message; if so: generating the maneuver message including the at least one possible trajectory, and sending the maneuver message via the communication network.
