    Abstract: A method is provided for partitioning probe data into a plurality of subsets, map matching a portion of the subsets and establishing a route based on the map-matched subsets of probe data. A method is provided that includes: receiving probe data points from a plurality of probes, where an uncertainty of the measurement of the probe data is a first distance; partitioning the probe data from the plurality of probes into subsets of probe data, where the subsets are created by ensuring each subset has probe data points that are at least two times the first distance apart from one another; performing map-matching on each subset of probe data; and establishing a route for each subset based on the map-matching of each subset of probe data. Establishing a route for each subset may include determining a route according to at least one of the shortest, fastest, or simplest routes.

    Abstract: In one embodiment, traffic data that originates from sensors, cameras, or observations is analyzed. The traffic data is associated with multiple repeating time epochs or intervals. The traffic data is divided into clusters using a clustering technique. The clustering technique may include clusters of variable sizes. Each of the clusters is analyzed to calculate statistical parameters including but not limited to an average value for one or more clusters and a standard deviation value for one or more clusters. In response to a request for traffic data, simulated traffic data may be generated by providing the average value and the standard deviation value for one or more of the clusters.

    Abstract: An approach is provided for node-based map matching. The approach involves processing probe data to sort a plurality of probe points according to sessions keys. The approach also involves selecting a subset of the plurality of probe points within a threshold distance of a node of a map representation of a transportation network. The approach further involves initiating a map matching of the probe points of each session key to the map representation by, for said each session key: (1) determining a closest probe point to the node; (2) determining another closest probe point to a neighboring node, wherein the neighboring node is connected to the node by at least one link; and (3) projecting the plurality of probe points between the closest probe point to the node and the another closest probe point to the neighboring node onto the link.
