  • Patent number: 11987261
    Abstract: A lead autonomous vehicle (AV) includes a sensor configured to observe a field of view in front of the lead AV. Following AVs are on the same road behind the lead AV. A processor of the lead AV is configured to detect a road structural change on the particular road. The processor updates driving instructions of the lead AV to navigate through the structural change using driving instructions related to the structural change. The processor sends a first message to the operation server indicating that the structural change is detected. The operation server updates the first portion of the map data, reflecting the structural change. The operation server sends the updated map data to the one or more following AVs.

  • Patent number: 11427224
    Abstract: Systems and methods for generating a virtual environment in a flock of vehicles are provided. In this method a reflector is utilized to define a coverage area. Sensory data from autonomous vehicles within this coverage area is collected, along with non-vehicle data. Then a virtual environment may be replicated using the data at a local computational device on each of the vehicles via the transmission of messages through the reflector. Each vehicle can use this data to make decisions regarding movements, as well as having the traffic patterns optimized based upon an objective. When traffic flow is being optimized it is also possible to assign weights to the vehicles to provide them preferential treatment in the traffic flow model. The traffic flow model that is generated may be a fluid dynamics model, or may be based upon deep learning techniques. The objective for the model is generally to maximize total vehicle throughput in order to reduce overall traffic congestion.

  • Patent number: 10896602
    Abstract: A method of determining whether one or more navigable elements of a navigable network within a geographic area are still affected by a precipitation weather event. A quantity parameter is associated with each segment of an electronic map representing the navigable network and indicates the amount of precipitation remaining on the navigable element or portion thereof represented by the segment. The value of the quantity parameter increases in the presence of any precipitation weather event, and decreases according to a predefined function with respect to time in the absence of any such precipitation weather event. A speed of travel of one or more devices along the navigable element or portion thereof represented by a segment is determined and compared to an expected speed of travel for the segment; the value of the quantity parameter being decreased based on the comparison.

  • Patent number: 10755558
    Abstract: An approach is provided for detecting venue trips and related road traffic. The approach involves, for example, processing probe data to identify a trip related to the venue. The trip is traveled by a probe vehicle generating the probe data within a timeframe associated with an event occurring at the venue. The approach also involves generating an influence graph comprising one or more roads used by the probe vehicle during the trip. The approach further involves determining a traffic parameter for the one or more roads of the influence graph. The approach further involves computing a traffic impact score for the venue, the event, or a combination thereof based on the traffic parameter.

  • Patent number: 10748421
    Abstract: The present invention relates to a method for estimating distribution of urban road travel time in considering operation state of taxi, and belongs to the technical field of urban transportation planning and management. The distributions of path travel time are respectively estimated according to different operation states of the taxi. When the distribution of the path travel time is estimated, adjacent road sections in the road network are not independent. In the present invention, the Markov model is added to describe the correlation of the travel time distribution between the adjacent road sections, so as to increase science and accuracy of the estimation result. In the present invention, the weight is set according to the proportion of the number of the vehicles under two different operation states to obtain the final distribution of the path travel time.

  • Patent number: 10565865
    Abstract: A plurality of instances of pre-intersection and post-intersection probe data are received. Each instance of pre-intersection probe data corresponds to traveling along a pre-intersection road segment before traveling through an intersection. Each instance of post-intersection probe data corresponds to traveling along a post-intersection road segment following traveling through the intersection. Instances of pre-intersection probe data are clustered into pre-intersection clusters based on a post-intersection road segment identified by the corresponding instance of post-intersection probe data. Instances of post-intersection probe data are clustered into post-intersection clusters based on the post-intersection road segment identified thereby. A traffic level indicator is determined for each cluster. A traffic level indicator difference is determined for each pair of corresponding pre-intersection and post-intersection clusters.

    Abstract: Disclosed herein is method and system for preventing traffic congestion of vehicles. Real-time traffic data related to a primary route being traversed by a vehicle, and location information of the vehicle are collected and analyzed to determine one or more alternative routes having less traffic congestion than the primary route. Further, congestion weightages are assigned to each of the alternative routes to identify an optimal route, having least traffic congestion, among the alternative routes. The optimal route is recommended to a user of the vehicle, thereby preventing traffic congestion. In an embodiment, the present method obtains the real-time traffic data directly from a computing device and/or one or more sensors integrated in the vehicle, and thereby accurately identifies the optimal route for the vehicle.
