A system (and method) includes at least one traffic server to receive traffic information reports transmitted from vehicles located on a traffic network serviced by the at least one traffic server. The traffic network is segmented into a plurality of predefined links, each predefined link associated with a priority level, a reporting latency, and an identification code. An onboard unit in a vehicle transmits traffic information reports to the at least one traffic server. The onboard unit is configured: to determine a current location of the vehicle; based on the current location, to determine on which of a link of the predefined links in the traffic network the vehicle is currently located; to determine a link identification code that corresponds to the link on which the vehicle is currently located; and to generate a traffic data packet to be potentially transmitted by the onboard unit to the at least one traffic server. The determined link identification code serves as indicia of location in the traffic data packet.

Filtering infrastructure description messages

A method for filtering infrastructure description messages packed in data packages, the messages being transmitted in a vehicular ad hoc network, along with positional information messages for the localization of individual participating nodes, in order to describe the status of the vehicular ad hoc network and/or a street on which the participating nodes are located. The method includes the following steps: receiving one of the infrastructure description messages at a participating node; evaluating the received infrastructure description message as to whether a response is required; and filtering the evaluated infrastructure description message based on a predetermined criterion for whether a response is required.

INFORMATION PROVIDING APPARATUS FOR VEHICLE

An information providing apparatus includes a traffic information database and a data processing device. The data processing device detects, based on the traffic information data, an impediment event. The data processing device extracts the impediment event potentially encountered by an assisted vehicle. The data processing device calculates, based on the traffic information data, a certainty level of the impediment event. The data processing device provides a driver of the assisted vehicle with a straightforward notification regarding the impediment event potentially encountered by the assisted vehicle and having the certainty level equal to or higher than a straightforward notification threshold. The data processing device provides the driver with an euphemistic notification, which is different from the straightforward notification, regarding the impediment event potentially encountered by the assisted vehicle and having the certainty level less than the straightforward notification threshold.

Broadcasting details of objects at an intersection

Methods and apparatus consistent with the present disclosure may receive different sets of image or sensor data that may be compared for inconsistencies. Each of these sets of received data may include images of a roadway or intersection that are processed to identify objects and object locations at or near the roadway/intersection. In certain instances data received from a camera at a traffic control system may be compared with data received from a computer at a vehicle. Alternatively or additionally, different sets of data acquired by a same or by different cameras may be compared for discrepancies. When one or more discrepancies are identified in different sets of received data, corrective actions may be initiated. In certain instances, such corrective actions may include recalibrating an image acquisition system or may include sending message to a vehicle computer that identifies the discrepancy.
