Abstract: 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.

Abstract: Example embodiments relate to methods and systems for performing management of a luminaire network. One example embodiment includes a method of performing management in a luminaire network that includes a plurality of luminaires and a control system. Each luminaire of the plurality of luminaires is configured to operate in accordance with at least one profile which defines one or more settings of the luminaire in function of time. The method includes retrieving, by the control system, traffic data from at least one traffic database, preferably vehicle and/or pedestrian traffic data. The method also includes retrieving, by the control system, weather data. Additionally, the method includes predicting, by the control system, for each luminaire motion related conditions for a future period of time based on the retrieved traffic data and the retrieved weather data, preferably motion related conditions influencing the motion behavior of vehicles and/or pedestrians circulating in the vicinity.

Abstract: Among other things, equipment is located at an intersection of a transportation network. The equipment includes an input to receive data from a sensor oriented to monitor ground transportation entities at or near the intersection. A wireless communication device sends to a device of one of the ground transportation entities, a warning about a dangerous situation at or near the intersection, there is a processor and a storage for instructions executable by the processor to perform actions including the following. A machine learning model is stored that can predict behavior of ground transportation entities at or near the intersection at a current time. The machine learning model is based on training data about previous motion and related behavior of ground transportation entities at or near the intersection. Current motion data received from the sensor about ground transportation entities at or near the intersection is applied to the machine learning model to predict imminent behaviors of the ground transportation entities. An imminent dangerous situation for one or more of the ground transportation entities at or near the intersection is inferred from the predicted imminent behaviors. The wireless communication device sends the warning about the dangerous situation to the device of one of the ground transportation entities.

Abstract: The disclosure provides a system, a method, and a computer program product for updating map data. The system, for example, receives, from one or more user equipment, at least one road works observation. The at least one road works observation is associated with a road works object. Further, the system, determines a first lane and a second lane. Further, the first lane is associated with the at least one road works observation and the second lane is associated with the road works object. Further, the system determines traffic density associated with a region in vicinity of the road works object. Further, the system detects the road works zone based on the first lane, the second lane and the traffic density.

Abstract: A vehicle control device includes an external situation recognition unit configured to recognize a crossing person who crosses over a path of a vehicle and acquire information on the crossing person and information on an environment where the crossing person crosses, a scheduled departure time deciding unit configured to decide a scheduled departure time of the vehicle based on the information on the crossing person and the environment where the crossing person crosses when the crossing person is recognized by the external situation recognition unit, and an informing controller configured to perform a control to inform an outside of the vehicle of the scheduled departure time. The scheduled departure time deciding unit predicts a crossing completion time at which the crossing person recognized by the external situation recognition unit completes the crossing and decides the scheduled departure time based on the crossing completion time.

Abstract: A vehicle control device mountable on a vehicle includes a warning device that warns a current driver of the vehicle, and a control system including a processor and a memory that are communicably coupled. The control system obtains, a numerical value indicating an acceleration operation and/or a deceleration operation for each past driver of the vehicle, and the numerical value as past operation data. When an occupant other than the current driver matches any past driver, the control system sets the past operation data of the any past driver as reference data. The control system obtains a numerical value indicating an acceleration operation and/or a deceleration operation by the current driver as current operation data, and controls the warning device to warn the current driver when the current operation data deviates from the reference data by an amount more than a warning threshold.

Abstract: A method of estimating an accident risk level of a first traffic participant based on interactions or negotiations of the first traffic participant with one or more other traffic participants is provided. The method includes generating a plurality of virtual trajectories of the first traffic participant based on a recorded initial position, a recorded final position of the first traffic participant, and a recorded initial position of each of the one or more other traffic participants. The plurality of virtual trajectories of the first traffic participant are associated with a plurality of virtual behaviors of the first traffic participant. The method further includes identifying a virtual trajectory that is most similar to a recorded trajectory of the first traffic participant. The method enables an automatic interpretation of an actual maneuver of the first traffic participant based on the virtual behavior of first traffic participant associated with the identified virtual trajectory.
