  • Patent number: 9008952
    Abstract: A system for managing vehicles on a road network includes a processor that performs operations including accessing a matrix of vehicle parameters of a plurality of communicating vehicles on the road network, and representing the plurality of communicating vehicles in a graph with a plurality of nodes corresponding to the plurality of communicating vehicles and with a plurality of edges corresponding to the vehicle parameters. The system can include partitioning, with the processor, the graph to reduce disruptions to the road network below a threshold level to support safe and efficient traffic flow, and assigning one or more exclusion zones within the road network to each partition of the graph by associating the vehicle parameters for each vehicle.

  • Publication number: 20150094941
    Abstract: Techniques are described for assessing road traffic conditions in various ways based on obtained traffic-related data, such as data samples from vehicles and other mobile data sources traveling on the roads and/or from one or more other sources (such as physical sensors near to or embedded in the roads). The road traffic conditions assessment based on obtained data samples may include various filtering and/or conditioning of the data samples, and various inferences and probabilistic determinations of traffic-related characteristics of interest from the data samples. In some situations, the inferences include repeatedly determining current traffic flow characteristics and/or predicted future traffic flow characteristics for road segments of interest during time periods of interest, such as to determine average traffic speed, traffic volume and/or occupancy, and include weighting various data samples in various ways (e.g., based on a latency of the data samples and/or a source of the data samples).

  • Patent number: 8996286
    Abstract: A system and method for providing a suggested modification to road characteristics is provided. Signals indicating locations of several users are received at different points in time. A flow of traffic corresponding to the several users is determined based on an analysis of the locations of the several users at the different points in time. A high traffic area is identified in the determined flow of traffic by comparing the determined flow of traffic with a predetermined baseline flow of traffic. Road characteristics in the identified high traffic area are analyzed and a suggested modification to at least one of the road characteristics based on the analyzing of the road characteristics is provided.

  • Patent number: 8976041
    Abstract: Methods, systems, and devices for monitoring roadway traffic. A method includes transmitting wireless signals from at least one roadside equipment (RSE) device and receiving responses by the RSE device from a wireless device, the responses including a unique identifier corresponding to the wireless device. The method includes determining a signal strength of each of the responses by the RSE device and transmitting response data from the RSE device to a control system, the response data including the unique identifier, the signal strength of each of the responses, and times that the responses were received. The method includes detecting at least one vehicle by the control system using a vehicle detection device and associating the response data with the detected vehicle. The method includes determining traffic information associated with the wireless device based on the received response data and the associated detected vehicle.

  • Patent number: 8972080
    Abstract: A traffic control system sets a target value related to a travel state based on a correlation between a vehicle travel speed and a traffic volume, and controls multiple vehicles (CS) on a road in accordance with the target value as a common target value. The target value can be set based on a predicted traffic volume at a region (103) that is ahead of, in a vehicle travel direction, the multiple vehicles on the road. For example, the traffic control system sets, as the target value, a target speed or a target value of a parameter related to an inter-vehicle distance.

  • Patent number: 8972159
    Abstract: Systems, methods, software, and apparatuses for coordinating traffic proximate to a potential conflict zone, such as a roadway intersection, where travel conflicts, such as crossing traffic, can arise. Coordination involves forming an ad-hoc network in a region containing the conflict zone using, for example, vehicle-to-vehicle communications and developing a dynamic traffic control plan based on information about vehicles approaching the conflict zone. Instructions based on the dynamic traffic control plan are communicated to devices aboard vehicles in the ad-hoc network, which display one or more virtual traffic signals to the operators of the vehicles and/or control the vehicles in accordance with the dynamic traffic control plan.

  • Patent number: 8966654
    Abstract: A novel privacy control-adjustable vehicle monitoring system and a related method of operation provide a dynamically-adjustable access grant or denial of privacy-sensitive vehicle information to a vehicle monitoring personnel based on a driver's response to an electronic request made by the vehicle monitoring personnel. In one embodiment, vehicle information is categorized into a mandatory disclosure dataset and a privacy-adjustable dataset, wherein the mandatory disclosure dataset is disclosed to the vehicle monitoring personnel at all times, while the privacy-adjustable dataset is accessible if the driver grants access via a driver's user interface on an onboard vehicle user interface, or on a mobile electronic device. Furthermore, a special wild card mode visible to the driver enables the vehicle monitoring personnel to access an entire set of vehicle information for a limited period per access and for a limited number of accesses per period, based on a pre-arranged consent with the driver.

  • Patent number: 8958988
    Abstract: A system for identifying a fastest possible travel route is disclosed. A traveler data processor collects traffic speed data and associates the traffic speed data with road segments. The road segments collectively represent one or more possible travel routes from a start point to an end point. A forecast engine determines a predicted travel time for each of the road segments based on, for example, the traffic speed data for each of the road segments. A routing engine determines the fastest possible travel route from the start point to the end point. The fastest possible travel route is the possible travel route from the one or more possible travel routes with the shortest predicted travel time.
