Region-Based OD Results
The results page provides a comprehensive overview of your study’s findings. To access it, click on your study once its status changes to results ready.
Pro Tip
At this point, you’ve created a region-based study including one or multiple regions and submitted your study to generate results. And iNode has then computed origin–destination (OD) matrices between your chosen regions.
This can result in tens or even hundreds of OD pairs, and iNode’s filtering feature allows you to refine these results and narrow down OD pairs and trip sets, so you can focus your report on the specific subset of data that matters most to your analysis. The filtering criteria include:
- Region-to-region filtering to show only certain origin regions, only certain destination zones, or specific OD pairs.
- Time of day/day of week filtering to include results based on a specific date/time range.
- Trip volume filtering to focus only on OD relations above a certain threshold.
There are seven tabs across the top:
- The info and summary tabs provide general details about the study.
- Results can be viewed in four visualization options: Matrix, Sankey, Flow map, and Histogram, each is presented in a tab.
- The Labels tab allows you to assign names and metadata to each study, making it easier to organize and manage projects.
Info
The info tab provides an overview of the study output, including:
- Project name
- Selected date ranges
- Selected time ranges
- Selected region geometries
The see results takes you directly to the map flow tab, where results are displayed visually.
Managing Your Study
Six options are available for managing your study:
- Download: Export the results in GeoJSON format.
- Archive: Save the study for record-keeping or future reference.
- Clone: Duplicate the study with all defined parameters. This is useful if you want to run the same setup for different date ranges, simply adjust the dates in the cloned order while keeping all other settings unchanged.
- Share: Generate a shareable link to give external stakeholders access to your report. When creating the link, you set an expiry date to control how long access remains active. Once the link expires, it can no longer be used to view the report.
- Check Status: View the current processing status of your report. This is useful for monitoring progress and confirming when results are ready to review.
- Delete: Permanently remove the study from your workspace
Summary
The summary tab provides an overview of the analysis, including:
- The total number of trips analyzed for the selected date ranges and time sets within the study area(s).
- The total length of road networks of FRC 0-5 within a convex hull that encloses the user-defined regions + 10 km external region (where applicable).
- iNode credit usage for the report.
- Detailed trip counts for each selected date and time range.
Matrix
Filter the Results
By default, the OD results will include OD pairs between all possible combinations of the defined regions based on the first selected date and time range.
You can filter to show desired origin and destination regions (OD pairs) by selecting a set of attributes, such as date/time range, trip volume, etc.
To set up your filters:
- Narrow the origins and destinations – Choose the regions you want to analyze.
- Select a via region (optional) – In the matrix view, you can refine results further by specifying a via region. This will filter the results to show numbers of trips between the selected origins and destinations that pass through a region selected as via.
Important Note
In region-based OD studies, only one region can be selected as a via region.
- Narrow date and time ranges – Choose the desired period(s).
- If multiple time sets are available (e.g., 24 hourly sets), you can either select a single time set (e.g., 7-8 AM) or multiple time sets (e.g., 8-9 AM, 9-10 AM, 10-11 AM) to aggregate the results (i.e., trip counts for three hours from 8-11 AM).
- Observed probe count – Set lower limit to filter results by count or percentage.
- For example, if the Lower Limit is set to 329, only regions with 329 or more trips (incoming or outgoing) will appear, excluding those below the threshold.
- If the user selects for the values in the OD matrix to be shown as percentages, these numbers represent the percentage of trips for that specific OD pair relative to the total number of trips across all OD pairs.
For example: If the number of trips from Zone A to Zone B is 20, and the total number of trips between all zones is 10,000, the value in the matrix for that cell is 0.2%
Interpret the Results
The trip counts displayed in the OD matrix on iNode represent unique origin–destination (OD) trips.
Trim to defined region studies
Here is an example of a filtered matrix for a study created as “Trim to defined region”. The matrix captures all trips that either:
- Originate inside your defined regions
- Originate outside your defined regions, and are attached to them where they were first and last observed.
Add to external region studies
If you created an Add to external region type of study, the matrix will include an additional external region row and/or column.
In this case, the matrix captures all trips that either:
- Originate inside your defined regions and end outside the study area, or
- Originate outside the study area and end inside your defined regions.
Instead of being excluded, these trips are grouped under the external region, giving you visibility into total inbound and outbound travel demand connecting your study area(s) to the wider network.
In the above matrix, the numbers represent unique trips within the selected date and time ranges.
- The number of trips that originated in region 8232_8234 and ended in region 8122_8123 is 2.
- The number of trips that originated from an External region and ended in region 2365_2370 is 114.
Important Note
If you have selected a via region, the matrix will show only unique trips that have passed through the via region.
Download the Results
All generated matrices can be downloaded in CSV format. Additionally, the full report is available for download in CSV format within this tab.
Pro Tip
Understanding unique trips in the full CSV export
When you download the full CSV matrix, the total number of unique trips for a specific origin–destination (O/D) pair is shown in the rows where the “via” region is set to either the origin or the destination.
Example
To find all trips from Avocet Dr_gate to Eagle Dr_gate, look for rows where:
- Origin = Avocet Dr_gate
- Destination = Eagle Dr_gate
- Via column = Avocet Dr_gate" or "Eagle Dr_gate
In some cases, a trip between two points must pass through an additional region. For instance, if a trip from Avocet Dr_gate to Eagle Dr_gate passes through Region, the trip count will be in the row:
- Origin: Avocet Dr_gate
- Destination: Eagle Dr_gate
- Via: Region
This is because the trip is treated as unique to that full path.
Important Note
For any O/D pair, the unique trip count (within the selected date range and time set) is found in the rows where the via region equals either the origin or the destination.
Sankey
In this tab, results can be filtered in the same way as in the matrix tab, but displayed as a sankey chart.
You can select:
- Origin
- Destination
- Date and Time
- Via Region (a region through which trips passed between the selected origin and destination)
- Lower Limit (to filter out results below a specified threshold)
Map Flow
Similar to the matrix and sankey tabs, the map Ffow tab allows the user to filter trip results between selected regions and view them on the map.
Histogram
In the histogram tab, you can set any region as the origin and destination, select a time set and date range, and generate charts based on one of the following dimensions: Start hour, Length, or Duration. Charts can also be downloaded for further analysis.
Start hour: Displays the number of vehicles that began their trips at each specific hour.
- Example: If the time set is 6:00 AM–10:00 AM, the chart will show the distribution of trips that started during that period.
- As shown in the example image, with the origin, destination, via region, and date range already set, the matrix indicates that 295 trips began between 8:00 AM and 9:00 AM within the 6:00–10:00 time set.
Length: Displays the number of vehicles that traveled a given distance (in kilometers) based on the regions defined in your analysis.
Duration: Displays the number of vehicle trips that lasted a specific amount of time (in minutes), calculated according to the regions defined in your analysis.
