Abstract: A method for calculating traffic flow changes includes detecting a traffic event. The method further includes determining an affected area of the traffic event and determining an investigation area based on the affected area. The method further includes selecting at least one vehicle located within the investigation area and calculating a change in traffic flow due to the traffic event based on a comparison of a predicted traffic flow with a current traffic flow, wherein the current traffic flow is based on information received from the at least one vehicle. The method further includes updating the affected area based on the change in traffic flow and calculating an updated change in traffic flow based on the updated affected area when the updated affected area is larger than a predetermined threshold area.

Abstract: An ability of a power transmission device to transfer electric charge in a power-transmission area at a particular point in time is identified. The ability comprises a threshold number of vehicles to which the power-transmission device can transfer electric charge with at least a threshold efficiency. A predicted number of electric vehicles that are likely to be requesting electric charge within the power-transmission area at the particular point in time is calculated. The number of electric vehicles that are likely to be requesting electric charge within the power-transmission area at the particular point in time is adjusted based on a determination that the predicted number of vehicles is not bound by the threshold number of vehicles.

Abstract: A method, computer system, and a computer program product for supplementing learning data to determine a Most Probable Path (MPP) for a user driver is provided. The present invention may include determining a change associated with a set of map data. The present invention may then include extracting a set of trajectory data in response to the determined change associated with the set of map data. The present invention may also include performing a rerouting calculation for the extracted set of trajectory data, wherein the performed rerouting calculation generates a rerouting result, wherein the generated rerouting result is added to a set of learning data in a learning data database. The present invention may further include adding one or more trajectory patterns to the learning data based on an increase frequency after the determined change associated with the set of map data.

Abstract: Generating routes based on aggregated path data includes accumulating trajectory data from a plurality of users, wherein data entries in the trajectory data each include an origin and a destination. When a request for a route from a designated location to a particular destination is received from a particular user, one or more of the data entries are identified as relevant to the request for the route when the origin of a particular data entry is similar to the designated location and the destination of the particular data entry is similar to the particular destination. Route recommendations are generated for the particular user based on one or more data entries identified as relevant.

Abstract: A method, system, and computer program product are provided. At least some received event candidate information concerning a possible event is stored as an event candidate in a database. A dialogue is generated with an occupant of a vehicle located in a vicinity of the possible event to obtain and store information to resolve any insufficiency or ambiguity regarding the event candidate in the database. When the information stored in the database regarding the event candidate is determined to be sufficient and unambiguous the event candidate is made into an event in the database. The event is reported to at least one vehicle approaching a location corresponding to the event.

Abstract: A method for transferring data among communication devices. The method includes a first communication device receiving, from a second communication device, data to be transferred and a condition defining a range of data transfer. The first communication device then determines whether a third communication device satisfies the condition defining the range of data transfer. On condition that the first communication device determines that the third communication device satisfies the condition, the first communication device directly transfers the data and the condition to the third communication device.

Abstract: A computer identifies social media displayed by a social media platform. The computer determines that a user has viewed the social media and saves the viewed social media in associated with the view date/time. The computer identifies and saves the interests associated with the user at the date/time the social media post was viewed by referencing the user profile and recent social media activity of both the user and associated users. The computer receives a social media query and cluster period from the user in regards to a previously viewed social media post. The computer displays the viewed social media that matches the search query as well as the interests associated with the user during each cluster period in which a matching social media post was viewed.

Abstract: A method and/or system for managing a database that stores space-time context objects is provided. The system receives a query range in a multi-dimensional space. The system maps the query range into a set of fragments of a space-filling curve that fills the multi-dimensional space in all dimensions of the multi-dimensional space. The system uses each mapped fragment in the set of mapped fragments as a key to query the database for space-time context objects that are mapped to the space-filling curve. The system queries the database by identifying one or more context objects that intersect the mapped fragment at the space-filling curve.
