Abstract: The disclosure provides a method, a system, and a computer program product in accordance with at least one example embodiment for detecting a roadblock zone. The method comprises receiving one or more road object observations, determining a map-matched link based on the received one or more road object observations, and calculating, at one or more locations associated with the map-matched link, heading difference data associated with a difference between a heading of each road object observation of the one or more road object observations and a heading of the map-matched link. The method further comprises identifying a set of locations from the one or more locations associated with the map-matched link where the heading difference data is more than a first predetermined threshold for each location in the set of locations and detecting the roadblock zone on the map-matched link based on the identified set of locations.

Abstract: An approach is provided for estimating lane pavement conditions based on street parking events. For example, the approach involves map-matching a vehicle park-in event, a vehicle park-out event, or a combination thereof to a lane of a road segment. The approach also involves calculating an adjusted pavement condition of the lane based on the map matched park-in event, the map-matched park-out event, or a combination thereof, wherein the adjusted pavement condition accounts for a reduction of a weather effect on a pavement condition of the lane caused by one or more vehicles parking in the lane. The approach further involves providing the adjusted pavement condition of the lane as an output.

Abstract: Embodiments described herein may provide a method for generating a local hazard warning boundary and at least one confidence band therein. Methods may include: receiving a plurality of probe data points from a plurality of probes within a region, where each probe data point includes location information and an indication of a hazardous condition; generating, based on the plurality of probe data points, a boundary within the region identifying an area within which the hazardous condition is determined to exist with at least a first degree of confidence; generating, based on the plurality of probe data points, a confidence band within the boundary within which the hazardous condition is determined to exist with a second degree of confidence; and providing for an indication of the boundary and the confidence band to at least one of an autonomous vehicle control or to a driver assistance system.

Abstract: A system, a method, and computer program product are provided for generating placement data of a road sign are provided. The method comprises obtaining a set of road sign observations that comprise sign placement label data and a first lateral offset value of each road sign observation of the set of road sign observations, determining, using a probabilistic model, a lateral threshold value based on distribution of the sign placement label data and the first lateral offset value of each road sign observation, and obtaining a second lateral offset value of the road sign. The method further comprises generating the placement data of the road sign based on the lateral threshold value and the second lateral offset value of the road sign.

Abstract: A system, a method, and a computer program product for validating a road sign are provided. The method comprises determining a transition location associated with the road sign using map data. The transition location is at least one of a map region start location or a map region end location. The method further comprises determining road sign data associated with the road sign using a sensor data cluster. The method further comprises determining a validity of the road sign based on the road sign data and the transition location.

Abstract: An approach is provided for operating a vehicle using vulnerable road user data. The approach, for example, involves determining a road link on which the vehicle is traveling or expects to travel. The approach also involves querying a geographic database for a vulnerable road user attribute of the road link. The approach further involves providing a notification to activate or deactivate an autonomous driving mode of the vehicle, a vehicle sensor of the vehicle, or a combination thereof while the vehicle travels on the road link based on determining that the vulnerable road user attribute meets a threshold criterion.

Abstract: An approach is provided for determining a navigation route based on vulnerable road user data. The approach, for example, involves generating one or more candidate navigation routes for a vehicle. The approach also involves querying a geographic database for vulnerable road user data for a respective set of road links comprising each of the one or more candidate navigation routes. The approach further involves selecting the navigation route from among the one or more candidate navigation routes based on the vulnerable road user data.

Abstract: An approach is provided for determining a negative observation of a road feature (e.g., traffic sign). The approach involves, for example, querying a spatial data structure for a set of location points based on a spatial radius around a location of the road feature. The spatial data structure stores a plurality of location points from a plurality of location traces that did not have a road feature observation. The approach also involves map matching each location trace in the set of location points to a matched path of road links. The approach further involves determining that said each location trace is a negative observation of the road feature based on determining that the location of the road feature falls between two map-matched location points of said each location trace that are on the matched path of road links.

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.
