Abstract: A method and system are disclosed for collecting and maintaining road event information, where point-based road event location data from transportation authorities, construction companies, vehicle sensors, or combinations thereof, is susceptible to location sensor errors, digital map errors, and/or map mismatching errors. Errors less than a selected threshold are filtered by categorizing or grouping reports of point-based locations into segments along links in a representation of a road, providing improved accuracy of reporting of road events.

Abstract: An approach is provided for aggregating an incident route based on high-resolution sampling. The approach involves receiving location data points representing a path traveled. The approach also involves generating an initial link set comprising a first predetermined number of traveled link options based on an initial location data point. The approach further involves determining a second predetermined number of probable matching road links of the geographic database for a next location data point. The approach further involves computing probabilities for respective pairs of the traveled link options and the probable matching road links. Each probability indicates a pair of a likelihood that a traveled route option and a probable matching road link are connected. The approach further involves aggregating the respective pairs to reduce a number of the respective pairs into the first or another predetermined number of traveled link options of a new link set based on the probabilities.
