Map Flows

If the analysis was calculated properly and accepted on the user's end, opening it from your My reports list will load a results page.

O/D Analysis results page showing left sidebar with analysis information — Analysis results page

TomTom O/D Analysis offers 5 different methods you can use to review the results. In this chapter we will focus on the first one - Map Flows.

Map Flows

This is an interactive report view that allows you to preview many different scenarios.

There are two ways you can mark given region either as origin or destination:

Using menu on the left side (Add Origin/Add Destination);

Left sidebar panel showing Add Origin button and Add Destination button with region selection dropdowns to the right of it — Origin/Destination selector panel of the Map Flows section

By clicking on given region and then selecting option;

The example on the screenshot below shows the result for one region selected as Origin (highlighted in grey). All other regions, in this case, became Destination and the outcome shows the distribution of trips in:

Percentage ratio - shown on the map;
Flows ratio - which is shown on the left side;

Map showing one region highlighted in gray as origin with colored destination regions displaying percentage values, and left sidebar showing flow distribution list with percentages — Map Flows results with only one region marked as **Origin**

These results contain additional information when you check Flows/km² option in the upper right corner. This option takes into consideration the size of the regions and compares it to the number of all the trips.

Map displaying regions colored by gradient with Flows per km² values shown, normalized by region area size, with legend showing value ranges — Map Flows results with Flows/km² option enabled

Another example of viewing the Map Flow results is to:

Select one region as Origin (highlighted in grey);
Select the other one as Destination (highlighted in grey);

All the other regions with the data available will be treated as Via automatically, showing how many vehicles traveled through them on their journey from Origin to the Destination.

Map showing one origin region and one destination region highlighted in gray with via regions displaying percentage values of trips passing through them — Map Flows results with one region marked as **Origin** and the other as **Destination**

NOTE! There is a possibility to make a screenshot of the analysis available in the upper right corner.
