  • Statewide work zone information system
    Patent number: 11869350
    Abstract: A computer system includes a memory and a processor. The processor executes instructions to perform steps that include receiving a message from an asset tracking device, the message comprising position information for the asset tracking device and a traffic control device type for a traffic control device that the asset tracking device is attached to. The processor uses the received message to determine a road that the traffic control device is positioned on and a location of the traffic control device along the road.

  • Freeway queue warning system
    Patent number: 10783787
    Abstract: A method includes using sensors to collect information about vehicles on a road and determining a plurality of crash probabilities based on the collected information. Each crash probability indicates a probability of a vehicular crash on the road at a respective point in time. The plurality of crash probabilities is averaged to form an average crash probability and the average crash probability is used to determine when to provide a message to a controller of a vehicle.
