Data analysis

Once a survey has been created, the data can be analyzed. Select the corresponding tenant to which your survey has been assigned. To make it easier to find the survey you are looking for, you can filter the surveys by name, the survey period (start and end date) and the selected map section.

Overview of the survey

In the Data Center you will find an overview of the BCAs used, the traffic classes evaluated, the time period or time zone and the locations of the survey shown on the map.

Traffic data

Nodes and relationships with flow data for the selected period are displayed. A maximum of 7 days is displayed. The period can be restricted using the slider below the display. The evaluated traffic classes can be restricted under “Displayed classes”.

When selecting a relationship between two nodes, traffic distribution, travel time and the license plate countries or, depending on availability, the associated regions are broken down.

Show subjourneys: If nodes of the midpoint type have been defined, subjourneys can also be displayed between cordon points. This gives you a more detailed evaluation of the relationships between cordon points via midpoints.

Dynamic Journey Time Filter

The Dynamic Journey Time Filter allows users to define travel time limits both globally for all links and individually for specific links. Changes can be applied temporarily or saved permanently. This feature enables flexible and precise control over which connections are displayed.

Purpose & Benefits

The Dynamic Journey Time Filter offers:

  • flexible adjustment of travel time boundaries
  • efficient and targeted data filtering
  • improved transparency through link-specific configurations
  • reusable filter setups thanks to persistent storage

Overview of Components

Global Filter

The global filter defines the default minimum and maximum travel time for all links.

  • Default value: 0 s – 1800 s
  • The global filter is applied whenever no individual filter exists for a link.
  • Changes to the global filter only take effect after clicking Apply.

Individual Filters for Links

Each link can be assigned its own travel time filter.

  • Individual filters override the global filter.
  • An individual filter entry displays the defined time range as well as a delete icon (🗑️).
  • The “Add filter for link” dropdown allows users to create any number of link-specific filters.
  • With “Delete all filters for links”, all individual filters can be removed at once.

Matrix View

The matrix button navigates back to the travel time matrices, where the filtered link data can be viewed in a tabular format. A calculation helper based on speed and air distance is available. This view displays the most recently saved values.

Two matrices are shown. The first represents the lower bounds of the travel time filters for individual links. The second shows the upper bounds of these filters. If no individual filter is defined, the cell is greyed out, and the global filter settings apply. The matrix displays the start nodes in the first column and the destination nodes in the first row.

By double-clicking a greyed-out cell, it becomes active, allowing an individual filter to be set for that specific link.

Click “Save changes” to permanently store the entered values.

Click “Discard changes” to reset all modifications.

Calculate Travel Times

Here you can calculate individual filters for all links based on speed and air distance. Click “Start calculation” and the filters will be computed and then saved automatically.

Actions and Buttons

✔ Apply

  • Applies the currently configured filters (global + individual).
  • Triggers a recalculation or re-filtering of the displayed data.
  • Changes are temporary until new values are applied or saved.

💾 Save

  • Permanently saves all current filter settings.
  • Saved values are restored automatically when the application is reloaded.

↩ Reset

  • Reverts all changes made since the last save.
  • Restores the previously saved state.

🗑️ Delete All Filters for Links

  • Removes all individual link filters.
  • Afterward, only the global filter is applied.

How the Filtering Logic Works

  1. Individual filters take priority: If a link has an individual filter, only that filter’s time range is applied.

  2. Fallback to the global filter: For links without an individual filter, the global filter is used.

  3. Filtering of data: After clicking Apply, all links are re-evaluated and filtered according to their corresponding filter settings.

Data export

The data can be exported in the form of an Excel table.
