Abstract: An approach is provided for traffic data blending based on road segment travel time reliability during traffic prediction. The approach involves, for instance, retrieving real-time traffic information and/or historical traffic information for each road segment within a geographic area. The approach also involves aggregating traffic flow speed data in the real-time traffic information to compute traffic pattern data for each road segment. The traffic pattern data includes static speed data of each said road segment. The approach further involves aggregating traffic flow speed data in the historical traffic information to compute travel time reliability index metric(s) for each said road segment. The approach further involves determining, based on the travel time reliability index metric(s), to use the traffic pattern data, a mean, or a percentile of a road segment travel time distribution in the historical traffic information for traffic prediction associated with each said road segment.

Abstract: An approach is provided for providing hybrid traffic incident identification. The approach, for example, involves processing traffic incident information received from at least one incident source to classify the traffic incident information as either well-formatted data (matching at least one previously stored incident code) or non-well-formatted data (not matching the previously stored incident code). The approach also involves converting the well-formatted data to an incident reporting format to generate a first output portion. The approach further involves extracting incident content from the non-well-formatted data. The extracted incident content represents the traffic incident information based on the at least one previously stored incident code. The approach further involves converting the extracted incident content to the incident reporting format to generate a second output portion. The approach further involves providing the first output portion and/or the second output portion as a hybrid incident output.

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: 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: An approach is provided for determining road work zone travel time reliability based on vehicle sensor data. The approach involves, for instance, aggregating telematic data generated by vehicles traveling within a geographic area, to detect a road work zone and/or active time period(s) thereof. The approach also involves identifying a start location and an end location of the road work zone. The approach further involves identifying a starting time point when one of the vehicles approaching the start location and an end time point when the vehicle passes the end location. The approach further involves calculating a time difference between the start and end time points as a travel time through the road work zone. The approach further involves aggregating the vehicle travel times, to compute work zone travel time reliability index(es) for the road work zone. The approach further involves providing the travel time reliability index(es) as an output.
