Abstract: An approach is provided for detecting a presence of a physical divider on a road segment. The approach, for example, involves receiving sensor data from a vehicle traveling a road segment. The sensor data indicates a distance from the vehicle to the physical divider, a cross-sensor consistency of detecting the physical divider between at least two sensors of the vehicle, or a combination thereof. The approach also involves determining that the sensor data indicates the presence of the physical divider based on determining that the distance is within distance criteria, the cross-sensor consistency is within consistency criteria, or a combination thereof. The approach further involves updating data provided by a physical divider signal from the vehicle to indicate the presence of the physical divider on the road segment.

Abstract: An approach is provided for detecting false positive slippery road reports. For example, the approach involves receiving a slippery road report from a vehicle. The slippery road report, for instance, indicates that a slippery road event is detected at a location based on sensor information collected by the vehicle. The approach also involves map matching the location of the slippery road report to the mapping data to evaluate a proximity of the location to at least one geographic feature that is designated as an area where driver behavior is expected to be at least one cause of the slippery road event. The approach further involves classifying the slippery road report as the slippery road false positive report based on the evaluation.

Abstract: An approach is provided for interpolating weather forecast reports for a forecast location having limited weather station access. The approach involves segmenting a plurality of weather forecast reports according to a plurality of segmentation categories, the plurality of segmentation categories representing respective one or more forecast parameters. The approach also involves determining respective values of the plurality of segmentation categories from each of the plurality of weather forecasts. The approach further involves selecting a representative value from the respective values for each of the one or more segmentation categories. The approach further involves combining the representative value for said each of the plurality of segmentation categories to generate an interpolated weather forecast report.

Abstract: A method, system, and computer program product is provided, for example, for identifying a type of road sign. The method may include receiving a plurality of observations for the road sign. The method may also include clustering the plurality of observations based on at least a location and a heading of the road sign. Further, the method may include filtering the plurality of observations in the cluster based on a speed value and a lateral offset of each of the plurality of observations. Also, the method may include identifying the type of the road sign based on the filtering.

Abstract: A method, apparatus and computer program products are provided for matching a transit vehicle to a trip. An example method may comprise receiving probe data, the probe data comprising at least one of identity information, location information, or time information corresponding to the transit vehicle, causing placement of the probe data into a queue, wherein a placement in the queue is dependent on how much of the trip the transit vehicle has completed as indicated by the probe data, and causing assignment of the transit vehicle to a single candidate trip from among a set of candidate trips comprising a scheduled arrival time at a next closest stop closest to a calculated arrival time.

Abstract: An apparatus is configured to perform a method for generating warning polygons for weather events in a geographic region. The method includes receiving measurement data from one or more sensors, identifying at least one location from the measurement data, identifying a map tile within a predetermined distance to the at least one location, generating a map tile cluster based on analysis of the at least one map tile, accessing an end-use constraint of the end-use device, the end-use constraint indicative of a constraint in processing on the end-use device, and calculating the warning polygon based on the map tile cluster and based on the end-use constraint such that the polygon intersects the geographic region.

Abstract: A method, system, and computer program product is provided, for example, for assisting a user of the vehicle in following a prescribed speed limit while travelling in the vehicle. The method comprises providing a speed limit related recommendation to the user of the vehicle. The method further comprises receiving an image data representing a posted sign, in a vicinity of the vehicle, the image data being detected by one or more image capturing devices. Additionally, the method comprises processing the image data received to determine an observed numerical value. The method further comprises calculating, by a processor, a sign reliability factor based on a function of at least the observed numerical value, a historic mean of one or more vehicle speeds at the time of sign observation and a standard deviation of the one or more vehicle speeds at the time of sign observation. Additionally, the method may include providing data for an indication of the speed limit to be followed by the vehicle.

Abstract: An approach is provided for publishing a road event message according to a hysteresis. For example, the approach involves processing a road report to determine a road event associated with a geographic location and a confidence metric of the road event. The approach also involves initiating a publishing of a road event message to indicate the road event for the geographic location based on determining that the confidence metric is greater than an upper threshold of a hysteresis. The approach further involves processing one or more other road reports to update the confidence metric of the road event. The approach further involves initiating a cancelling of the road event message based on determining that the updated confidence metric is less than a lower threshold of the hysteresis.

Abstract: An approach is provided for generating a volatility index for weather data. The approach involves retrieving weather data collected from one or more weather sensors over a temporal domain, a spatial domain, or a combination thereof. The one or more weather sensors provide the weather data for at least one geographic point. The approach also involves processing the weather data to determine volatility data for at least one weather attribute, wherein the volatility data represents how much the at least one weather attribute changes over the temporal domain, the spatial domain, or a combination thereof. The approach further involves generating a volatility index to represent the volatility data.

Abstract: An approach is provided for a confidence-based road event message. For example, the approach involves aggregating road event reports (e.g., slippery road event reports) from vehicles traveling in an area of interest. The approach also involves retrieving weather data records for the area of interest for a time period corresponding to the reports. The approach may further involve determining a data freshness parameter based on an age of the reports, and a number of vehicle generating the reports. The approach further involves calculating a confidence level for the road event based on the weather data records, data freshness parameter, number of the one or more vehicles, or a combination thereof.
