Abstract: The disclosure provides a system, a method, and a computer program product for detecting active road work zones. The system obtains first sensor data associated with a detection of a road work zone, using a first sensor type and obtains second sensor data associated with presence of at least one individual in the road work zone, using a second sensor type. Further, the system determines a confidence level associated with the detection of the road work zone based on fusing of the first sensor data and the second sensor data. The system classifies the detected road work zone as at least one of the active road work zone or a non-active road work zone, based on the confidence level. The system updates map data associated with a map of a region based on the classification.

Abstract: The disclosure provides a system and a method for virtual lane generation for a vehicle. The system may determine one or more paths associated with a lane pair of the vehicle. The lane pair may correspond to an ingress lane and an egress lane associated with a traffic signal intersection. The system may further aggregate the determined one or more paths corresponding to the lane pair, to generate a bounding path associated with the lane pair. The system may further generate a virtual lane based on the generated bounding path. The generation of the virtual lane may be based on determination of a plurality of lane shape points corresponding to the generated bounding path. The system may further store data associated with the generated virtual lane in a map database.

Abstract: The disclosure provides a system, a method, and a computer program product for validation of sensor data. The system may be configured to receive sensor data associated with a hazard. The sensor data may include at least a first time of occurrence of the hazard. The system may be further configured to determine a second time of occurrence of the hazard based on a time-space diagram associated with one or more vehicles that passed through a location of the occurrence of the hazard. The system may further calculate a validation result for the received sensor data based on a comparison of the first time of occurrence and the second time of occurrence, and an associated first predefined threshold.

Abstract: Embodiments described herein may provide a method for aggregating probe data to detect a road work event and generating, from the road work event, a work zone map overlay to inform navigational systems and autonomous vehicles. Methods may include: receiving probe data from a plurality of probe apparatuses traveling within a road network; identifying, from the probe data, a road work event within the road network; determining, from the road work event and the probe data, a work zone; generating a map overlay including the work zone, where the map overlay is independent from map data of the road network; providing the map overlay to at least one vehicle for use in combination with the map data of the road network; and providing for at least one of navigational assistance or at least semi-autonomous vehicle control based on the map overlay of the map data of the road network.

Abstract: An approach is provided for providing a recommended route and departure time combination based on real-time estimated times of arrival (ETAs). The approach, for example, involves determining a plurality of candidate routes between an origin and at least one destination. The approach also involves retrieving real-time information, historical information, predicted information, or a combination thereof associated with the origin, the destination, the plurality of candidate routes, or a combination thereof. The approach further involves calculating respective cost values (e.g., ETAs) for traveling for the plurality of candidate routes at a plurality of different departure times. The respective cost values are based on the real-time information, the historical information, the predicted information, or a combination thereof. The approach further involves determining a recommended route and departure time combination based on the respective cost values. The approach further involves providing the recommended route and departure time combination as an output.

Abstract: A system and method are provided for determining malfunctioning traffic signals and lights. A traffic signal pattern is identified. Probe reports are received from a device. A path is generated including the road intersection for the device using location data in the two or more probe reports. The path is compared to a traffic signal. An abnormal crossing is determined from the comparison. A malfunction of the traffic signal is determined based on the abnormal crossing.

Abstract: An approach is provided for traffic Signal Phase and Timing (SPaT) verification using sensor data and probe data. The approach involves, for instance, retrieving image data captured using a sensor of a vehicle traveling within proximity of a traffic light. The approach also involves processing the image data to identify at least one transition of the traffic light between one or more traffic light states. The approach further involves determining a transition time, a cycle time, or a combination thereof between the one or more traffic light states based on the identified at least one transition of the traffic light. The approach further involves performing a comparison of signal phase and timing (SPaT) data of the traffic light with the transition time, the cycle time, or a combination thereof and providing the comparison of the SPaT data as an output.
