Abstract:
1. A method of pre-processing probe data, the method comprising: examining a sequential dataset for a route of travel between two points; identifying at least one anomaly in the sequential dataset; identifying at least a first and a second datum of the sequential dataset wherein said first datum occupies a sequential position adjacent to the identified at least one anomaly; and inserting at least one non-anomalous datum to occupy a sequential position of the identified at least one anomaly in the sequential dataset, the at least one non-anomalous datum being determined based on one of extrapolation, smoothing and interpolation of the at least first and second datum, wherein the at least one non-anomalous datum is further determined based on at least one inference derived from at least one characteristic of the route, the at least one characteristic of the route being information other than vehicular data corresponding to the route of travel between the two points.
