Vehicle ClassA pie chart that represents the percentage of journeys in your analysis that were performed by each vehicle class.
Vocation BreakdownA pie chart that represents the percentage of journeys in your analysis that had each vocation.
Industry BreakdownA pie chart that represents the percentage of journeys by industry as defined by the primary NAICS code. The primary NAICS code is determined by the fleet operating the vehicle that is contributing to the data.

O/D Matrix

The O/D Matrix tab displays a dropdown list of different datasets regarding your O/D pairs, presented in a matrix.

Metrics

The following metrics are available in the O/D Matrix tab:

MetricDescription
Journey Count - PercentageThe percentage of journeys between the O/D pair relative to the total amount of journeys for the entire analysis.
Journey Count - TotalThe total number of journeys between the O/D pair.
Journey Count - Daily AverageThe average daily number of journeys between the O/D pair.
Trips per Journey - AverageThe average number of trips comprising the journey between the O/D pair. If no trip chaining factor was used, this value will be 1.
Trips per Journey - MedianThe median number of trips comprising the journey between the O/D pair. If no trip chaining factor was used this value will be 1.
Distance - AverageThe average distance traveled between the O/D pair (in kilometers or miles).
Distance - MedianThe median distance traveled between the O/D pair (in kilometers or miles).
Distance - Std DevThe standard deviation of the distance traveled between the O/D pair (in kilometers or miles).
Running Speed - AverageThe average speed for all vehicles traversing between an O/D pair, excluding any time stopped (in kph or mph).
Running Speed - MedianThe median speed for all vehicles traversing between an O/D pair, excluding any time stopped (in kph or mph).
Running Speed- Standard DeviationThe standard deviation of speed for all vehicles traversing between an O/D pair, excluding any time stopped (in kph or mph).
Travel Speed - AverageThe average speed between the O/D pair including any time stopped (in kph or mph).
Travel Speed - MedianThe median speed between the O/D pair including any time stopped (in kph or mph).
Travel Speed- Standard DeviationThe standard deviation of speed between the O/D pair including any time stopped (in kph or mph).
Journey Duration - AverageThe average travel time between the O/D pair (in minutes).
Journey Duration - MedianThe median travel time between the O/D pair (in minutes).
Journey Duration- Standard DeviationThe standard deviation of the travel time between the O/D pair (in minutes).
Idling Duration - AverageThe average time spent idling between the O/D pair (in minutes).
Idling Duration - MedianThe median time spent idling between the O/D pair (in minutes).
Idling Duration- Standard DeviationThe standard deviation of the idling time between the O/D pair (in minutes).
Time at Destination - AverageThe average amount of time spent at the destination until the next journey (in minutes).
Time at Destination - MedianThe median amount of time spent at the destination until the next journey (in minutes).
Time at Destination - Standard DeviationThe standard deviation of the amount of time spent at the destination until the next journey (in minutes).
Intra-Journey Stop Duration - AverageThe total stop time between trips that comprise a journey (in minutes). If no trip chaining factor was used, this value will be 0.
Intra-Journey Stop Duration - MedianThe median of the total stop time between trips that comprise a journey (in minutes). If no trip chaining factor was used this value will always be 0.
Intra-Journey Stop Duration - Standard DeviationThe standard deviation of the total stop time between trips that comprise a journey (in minutes). If no trip chaining factor was used this value will always be 0.
Important:

If the analysis includes some overlapping zones of the same role, or if there are zones set to passthrough, there is potential for overcounting in the data. If a journey starts or ends in an overlapping zone, the journey counts towards all applicable O/D pairs, because they are overlapping with one another throughout the journey. If this is an issue for your analyses, consider breaking your analyses into multiple views to avoid overlapping. This impacts counts and percentage % metrics. It may impact the interpretation of this metric as percentages are viewed as a proportion of the entire analysis.

Reminders

When viewing the O/D Matrix tab, remember the following:

  • At the top of each matrix, a colored legend describes what numerical values the colors on the matrices represent.

  • A blank spot on the matrix means that, due to our privacy filters, there is insufficient data between the O/D pair.

  • The middle diagonal of each matrix represents journey's where the Origin and Destination are the same. If you do not wish to view these pairs, switch off the Origin = Destination option, located at the top of the screen.

  • Hovering over a cell reveals a popup that tells you to which Origin and Destination it is attached, as well as the value it has for the metric you are viewing.

  • The last Destination column and the last Origins row indicates the Sum. The Sum represents the sum of Origins and Destinations that are contributing to most traffic or journeys. This is used to understand which Origins and Destinations have the most activity. The Sum is applied to the Journey Count, under Percentage, Total, and Daily Average. Hover over the cell of the last row or column to get a tooltip of quick statistics.

  • Clicking a cell pulls up the map with the O/D pair labeled and an animated arrow representing the journeys between that O/D pair. Origins are displayed on the map in blue, while Destinations are displayed in orange. To view more information about the O/D pair, click View details.

Expansion Factors

The Expansion Factors tab displays reference locations to help you estimate ground-truth counts from Altitude counts.

By default, the map shows your purchased datasets. From the table filters, you can select the Specificity of expansion: State or Counties.

State and county level Expansion Factors are derived using a weighted average across road segments within each state or county. Aggregations are grouped based on road types and vehicle groups. View the Expansion Factors: Technical White Paper v3.0 for more information.

State

When you select State, the table displays information for all states included in your purchased datasets. Select a state from the map or the table to view details. States with limited data have a warning pill, as the expansion for them is done by referencing expansion factors from adjacent states.

Counties

For Counties, you must select each state you want to view from the dropdown menu. Toggle States with purchased datasets only to OFF to view all states. Click any county from the list after selecting a state to open a side window that provides expansion insights. Click View state for state details.

Note:

Expansion Factors are only available in the USA.
