Method for energy generation and traffic regulation using traffic movement
11312250 · 2022-04-26 · ·

A traffic regulation system and method which combines energy harvesting from the movement of a plurality of vehicles on a roadway with wireless directional power beam transmission using the harvested energy to encourage compliance with traffic regulations. Electric power is generated from the movement of the moving vehicles by using a wind turbine to harvest wind energy from the movement of vehicles or by piezoelectric plates which harvest compression energy from the weight of the vehicle tires on the road surface. The electric power is transmitted to electric or hybrid vehicles which comply with the traffic regulations. The traffic regulations are one of driving at a posted speed and driving at a safe following distance. A control system adjusts the traffic regulation based on measurements received from a plurality of detectors.

Latent space model for road networks to predict time-varying traffic

A method for traffic prediction of a road network includes receiving past traffic information corresponding to multiple locations on the road network. The method further includes determining, by a processor and based on the past traffic information, temporal characteristics of the past traffic information corresponding to changes of characteristics over time and spatial characteristics of the past traffic information corresponding to interactions between locations on the road network. The method further includes predicting predicted traffic information corresponding to a later time based on the determined temporal and spatial characteristics of the past traffic information. The method further includes receiving detected additional traffic information corresponding to the later time. The method further includes updating the temporal characteristics of the traffic information and the spatial characteristics of the traffic information based on the predicted traffic information and the detected additional traffic information.

Interactive Traffic System, Method and Control Devices
20220013009 · 2022-01-13 ·

A traffic control device system and method for communicating with autonomous and semi-autonomous vehicles. The traffic control device includes a base adapted to be placed on a surface, a body portion joined to the base portion and extending therefrom, and a communication module joined to or integral with the base or body portion. The communication module includes a transmitter adapted to transmit a signal from the traffic control device to one or more autonomous or semi-autonomous vehicles, wherein the signal includes information that can be used by the one or more autonomous or semi-autonomous vehicles to affect or control at least one system of the vehicle.

Restricting areas available to autonomous and teleoperated vehicles

A vehicle policy server maintains a set of policies for constraining operations of one or more remote vehicles. The policies may specify areas, locations, or routes that specified vehicles are restricted from accessing based on a set of acquired information. An application programming interface (API) enables programmatic updates of the policies or related information. Policies may be enforced by transmitting control signals fully or in part to onboard vehicle computers or to a teleoperation support module providing remote support to the vehicles using human teleoperators and/or artificial intelligence agents. The control signals may directly control the vehicles or teleoperation, or may cause a navigation system to present known restrictions in a suitable fashion such as generating an augmented reality display or mapping overlays.

Marker detection method and vehicular system

A marker detection method in which a magnetic detection unit (11) of a vehicle side that includes a plurality of magnetic sensors arranged in a vehicle width direction is used to detect magnetic markers (10) that are laid in a road, the method executes detection of a center position in the vehicle width direction of a magnetic distribution that acts on the magnetic detection unit (11) and processing of an index representing a degree of a positional change of the center position when a vehicle (5) passes over the magnetic markers (10) to determine a possibility of the presence of magnetic generation sources that causes disturbance, thereby suppressing erroneous detection of the magnetic markers (10).
