    摘要: There is provided a method for generating traffic data indicative of a traffic volume and/or traffic density within a navigable network in an area covered by an electronic map, the electronic map comprising a plurality of segments representing navigable elements of the navigable network. The method generally comprises obtaining data indicative of a count of devices associated with vehicles traversing the navigable element represented by the segment in respect of a given time, wherein the count of devices is based on positional data and associated timing data relating to the movement of a plurality of devices associated with vehicles along the navigable element represented by the segment; and using the determined count data and an scaling coefficient to obtain data indicative of an estimated traffic volume for the segment in respect of the given time, wherein the scaling coefficient is time dependent.

    摘要: An apparatus and method are provided, which allow vehicle drivers to be efficiently warned of approaching accident-prone road sections. For this purpose, geographical coordinates of a moving vehicle of a driver are compared with geographical coordinates of boundaries of each of one or more pre-stored accident-prone road sections within a geographical area of interest. As a result of said comparison, an approaching accident-prone road section is determined for the moving vehicle. When the distance between the moving vehicle and the approaching accident-prone road section is equal to a threshold distance, a warning signal is generated and outputted to the driver. The warning signal comprises information about the approaching accident-prone road section that is defined based on accident-related data for each traffic accident occurred on the approaching accident-prone road section during a time period of interest.

    摘要: The systems and methods herein utilize interactive Gaussian processes for crowd navigation. For example, an encoder receives sensor data and context information. The encoder also extracts interaction patterns from observed trajectories from the sensor data and context information. The encoder further generates a static latent interaction graph for a first time step based on the interaction patterns. A recurrent module generates a distribution of time dependent static latent interaction graphs iteratively from the first time step for a series of time steps based on the static latent interaction graph. The series of time steps are separated by a re-encoding gap. The decoder generates multi-modal distribution of future states based on the distribution of time dependent static latent interaction graphs.

    摘要: A method can be used to provide smart notifications to avoid collisions while the vehicle maneuvers in a tight structural environment, such as a home garage or an underground parking lot. The method includes receiving historical vehicle-trajectory data. The historical vehicle-trajectory data includes the location and the heading of the vehicle for each of the plurality of historical trajectories along the structure. The method further includes clustering the plurality of historical trajectories of the vehicle along the structure by types of maneuvers to generate a plurality of trajectory clusters. The method also includes creating a probability distribution bitmap using the plurality of trajectory clusters and creating a topographic map based on the probability distribution bitmap.

    摘要: The invention relates to a method and to a device for analyzing a sensor data stream, which characterizes a vehicle environment, with respect to a presence of traffic scenarios. The invention further relates to a method for guiding a vehicle. A similarity measure, which indicates the degree of correspondence between a section of the sensor data stream and at least one template stored in a database, is determined by mapping the section of the sensor data stream to the at least one template, preferably by means of dynamic time normalization. The template thereby characterizes a known traffic scenario. The known traffic scenario is assigned to the section of the sensor data stream, if the similarity measure satisfies a predetermined similarity criterion.
