Domicile Activity analysis

Domicile Activity is a type of stop analysis used to observe a commercial vehicle's duty cycle. This analysis looks at the driving activity between when a vehicle leaves and returns to the location where it stops the longest.

Running a Domicile Activity analysis

Learn how to run a Domicile Activity analysis, including selecting zones, adjusting filters, and viewing the results.

From the main menu, select Stop Analytics. The Analysis Area panel displays.
Click + Select zones.
Either Search for a region or choose from the Country options.
Select a Province or State.
1. If you choose a State, you must choose a County before selecting a City.
  Note:
  When a ZIP falls outside a City, but falls within a County the option for Outside City Limits displays. Only purchased datasets display as options. Click the information icon to view how to purchase unavailable geographies.
Click Continue.
Select Domicile Activity as the Stop Behavior.
Select the Zone type to analyze (County, City, ZIP, TAZ, or Census Tract).
Adjust the Domicile Activity Filters by clicking on the Edit button. Update your filters, then click Done.
Click Run Domicile Analysis. A popup message displays the estimated loading time to validate your analysis. After validating the analysis, the screen displays information about the next steps and what to expect in terms of time until you can see the results.

Once the analysis is complete, you see the map with your outlined type of aggregation in the center of the screen. The summary of your analysis is displayed at the bottom of your screen in the Overview table.

Domicile Activity filters

Understand the various filters and settings available in the Domicile Activity analysis, including date range selection, vehicle classification, vocation analysis, industry designation, fuel types, and vehicle eligibility comparison. It also details the definition and customization options for duty cycles.

Date range

Allows you to select up to four date ranges for one stop analysis. The stop analysis will only take into account stops that started and ended within these dates. The ability to select multiple date ranges allows you to cover patterns over a broad time without having to analyze all the data.

Vehicle class

Allows you to select the vehicle's classification type. The vehicle's VIN is used to determine the Gross Vehicle Weight Rating (GVWR). The GVWR is then used to assess its vehicle classification. Refer to the Data Dictionary for more information on the specific quantifiers of each vehicle class.

Vocation

Geotab has a patented machine learning algorithm which is used to determine the purpose or job (vocations) of the vehicles from which we collect data. You can select multiple vocations for an analysis. Refer to the Data Dictionary for details.

Industry

Whenever available, Geotab has assigned a primary industry designation to the vehicles contributing to the analytics. These classifications are based on NAICS primary industry code. Refer to the Data Dictionary for information on NAICS codes and their corresponding industries.

Fuel Types

Indicates the fuel type of the vehicle, determined from the VIN.

Vehicle eligibility comparison

Compare eligible vehicles against all vehicles in the dataset by toggling Comparison on.

Minimum duty cycles from domicile: Choose the minimum number of times a vehicle must leave its domicile and return to end its duty cycle. Calculated based on the entire analysis period.
Maximum travel distance of duty cycles: The maximum distance a vehicle can travel within a duty cycle to still be considered eligible.
Required percentile of cycles under limit: Adjust the percentile of a vehicle’s duty cycle travel limit to meet eligibility criteria.

Duty cycle definition

By default, after a vehicle returns to their domicile, the first stop event within the location area is counted as the end of a duty cycle. To choose this scenario, toggle Stop back at domicile.

Alternatively, toggle Custom stop duration to ignore short stops back to the domicile and defining how long a stop has to be to count as the end of a duty cycle.

Duty cycle trip distance

Set a minimum duty cycle travel distance.

Percentiles to surface

Configure the percentiles of distribution for stop duration, idle duration, before and after trip duration, before and after trip distance.

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.
