  • Patent number: 11145200
    Abstract: Systems, methods, algorithms, and software for DSRC-actuated traffic control are presented. The invention leverages the presence of DSRC radios in vehicles and gives priority (by displaying green light) to approaches (roads) that include DSRC-equipped vehicles.
    Type: Grant

    Inventors: Ozan K. Tonguz, Rusheng Zhang
  • Patent number: 11069236
    Abstract: Disclosed herein is an implementation of a Virtual Traffic Lights (VTL) application implemented as an app on a mobile computing device in which online mapping services provide information necessary to determine a lead vehicle among one or more vehicles approaching an intersection. The lead vehicle controls status of virtual traffic lights at the intersection. The information retrieved from in the online mapping service may be used to determine whether vehicles approaching intersection are moving closer or farther apart from each other, the direction of travel of the vehicles, the geographic location of the intersection, and the distance between each vehicle and the geographic location of the intersection.

  • Publication number: 20200265717
    Abstract: A system and method for providing virtual traffic lights in non-ideal situations in which vehicle-to-vehicle communication between IDLE vehicles approaching an intersection may be blocked by buildings or other obstructions at the corners of the intersection is presented. The method, using a distributed artificial intelligence approach, requires that vehicles approaching an intersection, unless receiving a message indicating that another vehicle at intersection has been declared the lead vehicle for purposes of controlling access to the intersection, must slow down or stop at the intersection to and assume the role of lead vehicle.

  • Publication number: 20190347933
    Abstract: A method of implementing an intelligent traffic control apparatus comprising providing a traffic control apparatus with a reinforcement learning based control system for a given traffic location; training the reinforcement based control system for the given traffic location on a simulator that simulates the given traffic location in a training environment, wherein the reinforcement learning based control system receives only partial traffic detection in the training environment on the simulator; and coupling the reinforcement learning based control system to the traffic control apparatus at the given traffic location after training. Specifically, the reinforcement learning based control system to the traffic control apparatus can function with improved results over current controls when less than 80%, and generally at least 5%, of vehicles are detected.

  • Patent number: 10077060
    Abstract: A system includes a transceiver for receiving one or more communications from a communication device in a railway vehicle; a microcontroller that is configured for communication with the transceiver and that is configured to control a position of a switch in the railway; and an electronic subsystem for interfacing with the microcontroller and with the switch; wherein the transceiver is configured to transmit to the microcontroller at least one of the one or more communications received from the railway vehicle; wherein the microcontroller is further configured to extract a command from the parsed contents; wherein the microcontroller is further configured to transmit the command to the electronic subsystem to cause the electronic subsystem to transition the switch to a position specified by the command; and wherein transitioning of the switch to the specified position enables the railway vehicle to cross the switch.

  • Patent number: 9524642
    Abstract: A method performed by one or more processors, comprising: receiving a notification message indicative of an occurrence of an event; determining that a position of a vehicular device that is associated with the one or more processors is located on a boundary of a reachability area surrounding a source of the event; determining that a direction of movement of the vehicular device is towards the source; responsive to determining that the position is on the boundary of the reachability area and that the direction of movement of the vehicular device is towards the source, entering a roadside unit state; detecting one or more vehicular devices that are uninformed of the occurrence of the event and that are located outside of the reachability area; and broadcasting the notification message to the one or more uninformed vehicular devices.

  • Patent number: 9478142
    Abstract: A method performed by a first rolling stock, comprising: receiving one or more communications from one or more second rolling stock, with a railroad network comprising the first rolling stock and the one or more second rolling stock; executing, by the first rolling stock, one or more of a local rule and a global rule; determining, based on executing, a speed for the first rolling stock relative to a speed of at least one of the one or more second rolling stock; and controlling the speed for the first rolling stock in accordance with the determined speed, wherein controlling promotes avoidance of a collision between the first rolling stock and the at least one of the one or more second rolling stock.
