Path data for Traffic Analytics

HERE offers path analysis as an additional option in Traffic Analytics. When you select this option, HERE uses the power of the HERE Map to determine the route that a vehicle takes between two sequential observation points. It allocates the time between those two points across the whole path, and calculates an effective speed. Also known as “space mean speed” analysis, this technique effectively adds more independent observations to the overall data set, increasing both coverage and quality. You can select this option for each Traffic Analytics query.

If you choose to include paths, then Traffic Analytics adds data to the dataset derived from the paths traveled between probe points. Using the highly accurate HERE Map, Traffic Analytics calculates the route taken by that vehicle, and if it can do so with high confidence, it applies the space mean speed observations (distance travelled / time taken) from that path to all the map links traversed by the path. Path speeds are equally weighted with probe speeds in calculating the mean and percentile speeds, as shown in the following image:

Harmonic mean, vehicle distance traveled (VDT), and probe count rely on path data. To access these enhancements, you must select "Path Data" exclusively as the source data, as shown in the following image:
