Origin-destination analysis looks at how traffic flows between various areas and instantly shows the difference in traffic through an easy-to-read matrix. Each area can be both an origin and a destination.
The Origin-destination analytics page displays a section with one or multiple matrices and a data distribution panel to configure the type of matrix, select a time range and time zone, define areas of interest, and apply data filters.
Click on Origin destination in the navigation panel on the left.
Similar to the Trend analytics, the first time you open this page, it will load with a number of default settings:
The time range box focuses on the last day, and the day before in the data set.
The configuration box compares the number of trips between these two days for all origin-destination pairs.
The areas of interest box automatically selects 3 areas from your drawing layers and uploaded GeoJSON shapes. In this case, traffic flows between Antwerp, Rotterdam, and Hamburg are visualized as you have downloaded the areas of interest document in a previous tutorial, Visual analytics.
The matrices show the absolute number of trips.
Because we have a time range active that compares two time periods, the analysis for the first day is shown in the first matrix (time period one), and the analysis for the second day is shown in the second matrix (time period two). The third matrix shows the difference between the traffic activity of time period one and two.
Let’s look in more detail what the origin-destination analysis can teach us. For this, let’s focus on the port areas Rotterdam, Antwerp, and Hamburg for the past week and the week before:
Click on the (x) on the
Suez chip in the AREAS OF INTEREST panel to remove the area
On the TIME RANGE panel
Last Week vs Week Before
We should now see 3 matrices with dimensions 3x3 each.
The numbers indicated are the number of vessels that move between the origin (labels on the left) to the destination (labels at the top). We see a slight increase for all traffic between Antwerp and Rotterdam and vice versa and a slight decrease for traffic between Rotterdam and Hamburg and vice versa.
These numbers are absolute numbers, and sometimes it is more informative to use percentages. To do so, there are two possibilities:
Hover with the mouse over the matrix and you see a tooltip on each matrix also indicating the percentages and the percentage change.
Select Percentage of trips (same origin) or Percentage of trips (same destination) from the dropdown box in the CONFIGURATION panel on the top right of the page.
You can now see what percentage of trips start or go to a certain area.
Let’s bookmark this analysis by clicking on the bookmark icon found at the top right of the screen and naming it
Origin Destination Ports.
