Trip definition

Our algorithms analyze the probe traces coming from each device. The analysis recognizes the pattern of a regular trip within any area. Probe traces are sequences of probe points that come from the same device. These sequences define the concept of a trip.

Our systems behind the O/D Analysis tool connect all these probe points, also known as GPS pings, with a single line and that line of connected pings creates a single vehicle trip, with its start and end points.

The GPS pings of a trip originate from the same anonymous device ID to make sure we are dealing with the same unique journey while calculating the analysis results.

The trips come from completely anonymized data and guarantee a high level of security. This protects individual devices from being associated with specific drivers.

Selected Link analyzes the portion of each trip that passes within the Radius you set around the selected link or region. Anything a trip does beyond that radius is trimmed and left out of the results.

For both a link and a region, results split into Incoming and Outgoing trips — those that end or start their journey near the selected geometry. A region also adds a third case: Inside trips, which pass all the way through. An Inside trip shows the path a vehicle took from the entrance it used to enter your region to the exit it used to leave it, letting you see how traffic flows between different entrances and exits.

NOTE! Keep in mind that due to privacy precautions, the true starts and ends of a trip are trimmed in addition to this radius-based trimming. For example, if a vehicle ended its journey at a specific household address, it will not be possible to pinpoint that trip to a specific person living in that area.
