Among other things, one or more techniques and/or systems are provided for providing users with access to a route for travelling. A user, of a client device, may send a request for access to the route to a route planning service. The route may correspond to a starting location and an ending location. The route planning service may query a route database to identify an entry indicating that a restricted access road segment (e.g., a high occupancy vehicle lane, a shoulder lane, a bus lane, etc.) and/or a road segment (e.g., comprising a traffic light alteration capability) exists between the starting location and the ending location. Responsive to successfully authorizing the user for travelling the restricted access road segment and/or the road segment, the route, comprising the restricted access road segment and/or the road segment, may be provided to the client device.

A computer-implemented method of generating and broadcasting telematics and/or image data is provided. Telematics and/or image data may be collected, with customer permission, in real-time by a mobile device (or a Telematics App running thereon) traveling within an originating vehicle. The telematics data may include acceleration, braking, speed, heading, and location data associated with the originating vehicle. The mobile device may generate an updated telematics data broadcast including up-to-date telematics data at least every few seconds; and then broadcast the updated telematics data broadcast at least every few seconds via wireless communication to another computing device to facilitate alerting another vehicle or driver of an abnormal traffic condition or event that the originating vehicle is experiencing. An amount that an insured uses or otherwise employs the telematics data-based risk mitigation or prevention functionality may be used with usage-based insurance, or to calculate or adjust insurance premiums or discounts.

A system and a method manage wireless traffic signals in order to aid autonomous driving systems and humans to quickly and accurately detect traffic signal changes and surrounding traffic. The system includes a plurality of road vehicles. Each road vehicle includes a vehicle receiver, a vehicle controller, and a vehicle output device. The system also includes a plurality of traffic-signal sources and a plurality of signal emitters. Each signal emitter is associated to a corresponding traffic-signal source from the plurality of traffic-signal sources. Each signal emitter processes traffic signals from the corresponding traffic-signal source and sends the processed traffic signals to the vehicle receivers. The vehicle receivers receive signals from the plurality of signal emitters. The vehicle controller processes the signals received by the vehicle receiver. The vehicle output device executes instructions that are extracted from the signals processed by the vehicle controller.

A facility for providing vehicle to vehicle event notification for connected and/or unconnected vehicles is disclosed. The facility enables a vehicle to detect an occurrence of a vehicle status trigger event and identify information describing an event type. The facility determines a priority of the vehicle status event based at least in part on the type of the vehicle status event. When the vehicle status event is to be reported to at least one other vehicle, the facility enables the vehicle to generate a vehicle status event message that includes the priority of the vehicle status event and at least a portion of the information describing the type of the vehicle status event. The vehicle status event message is then transmitted/broadcasted to at least one other vehicle.

A message transmission method for a roadside equipment includes the following steps. A plurality of external sensor information is received. A road intersection sign phase information and a road map information are inputted. An object position analysis, a speed analysis, and an sign analysis in object moving direction are performed based on the external sensor information, the road intersection sign phase information, and the road map information, and a classification of dangerous objects in different groups is outputted. According to a current transmission bandwidth limitation and the classification of the dangerous objects, a dangerous object message with a higher classification of the dangerous objects is preferentially selected and transmitted within available transmission bandwidth.

In one embodiment, an attribute application associates content with a road segment. In operation, the attribute application generates a spatial reference identifier based on coordinates associated with the attribute. The attribute application then generates an attribute based on the content and the spatial reference identifier. Finally, the attribute application transmits the road segment attribute to a navigation system that performs at least one navigation operation based on a road database and the attribute. Because the attribute is specified based on spatial referencing, the attribute application requires fewer resources to generate attributes than conventional approaches that generate different attributes for different versions and formats of road databases.

A method includes calculating a first adaptive threshold based on uncertainty of a first parameter of a first collaborative perception message (CPM) from a first node and uncertainty of the first parameter of a second CPM from a second node, calculating a second adaptive threshold based on uncertainty of a second parameter of the first CPM and uncertainty of the second parameter of the second CPM, obtaining a first association matrix by filtering out one or more pairs whose score is greater than the first adaptive threshold, obtaining a second association matrix by filtering out one or more pairs whose score is greater than the second adaptive threshold, obtaining a fused association matrix based on the first association matrix and the second association matrix, and implementing a fusion algorithm on the fused associated matrix to obtain correspondence identification among objects.

A method (and system, apparatus, and computer product) for reporting traffic data includes, in an onboard unit installed in a vehicle, generating a traffic data report packet including information identifying a location of the vehicle in a traffic network and storing the generated traffic data report packet in a transmission queue. The onboard unit stores and maintains the generated traffic data report packet in the transmission queue with other traffic data report packets in a sequence in accordance with potential transmission times associated with each traffic data report packet. At least a portion of the traffic data report packets stored in the transmission queue is selectively transmitted, as a batch transmission to a traffic center server via a communication link.

Aspects of the present disclosure include methods, apparatuses, and computer readable media for receiving a plurality of requests, from a plurality of user equipments (UEs), to exit a parking area comprising a plurality of vehicles, wherein each of the plurality of UEs is associated with a corresponding vehicle of the plurality of vehicles, determining an exit order for the plurality of vehicles to exit the parking area, and transmitting, to the plurality of UEs, a plurality of exit commands, based on the exit order, for the plurality of vehicles to exit the parking area.

An object is to share information of detected obstacles on a road among communication devices, using efficient communication. A communication device according to the present disclosure includes: a wireless receiving unit for receiving wireless information including first obstacle information of a first obstacle which is at least one obstacle, from outside; a first obstacle extraction unit for extracting the first obstacle information from the wireless information; a second obstacle detection unit for detecting second obstacle information of a second obstacle which is at least one obstacle present in an own surrounding area by a sensor; and an overlap information removing unit which, if there is overlap obstacle information between the first obstacle information and the second obstacle information, removes the overlap obstacle information from the second obstacle information, to generate difference obstacle information.
