Step 4: Using the origin-destination capability

Origin-destination analysis looks at how traffic flows between different areas. Each area can be both an origin and a destination.

Click on Origin destination in the navigation panel on the left.

Step 4.1: Look at how traffic flows between different neighborhoods in a city

Similar to the Trend analytics, the first time you open this page, it will load with a number of default settings:

Figure 1. Default origin-destination view, comparing the last day with the day before.
  • It focuses on the last day in the data set.

  • It computes the Number of trips between all origin-destination pairs.

  • It selects 3 areas or less from your drawing layers and uploaded GeoJSON shapes.

  • It shows absolute number of trips.

When analyzing two periods (you can do so by clicking on 2 PERIODS), the analysis for the first day is shown in the first matrix, the analysis for the second in the second, and the third matrix shows the difference.

Step 4.2: Understand origin-destination matrices and the different visualization modes

Let’s look in more detail what the origin-destination analysis can teach us. For this, let’s focus on the two areas we have been working with: Our own created Highway 1 shape and the uploaded Steinwerder shape:

  • Click on 2 PERIODS in the CONFIGURATION panel on the top right.

  • Select Last Day vs Day Before in the drop-down box next to it.

  • Press CLEAR ALL in the AREAS OF INTEREST panel.

  • Search for Highway 1 and press ADD.

  • Search for Steinwerder and press ADD.

We should now see 3 matrices with dimensions 2x2 each.

Figure 2. Origin-destination analysis for our own created area and the Steinwerder neighborhood.

On the first day, we see that there are 80 trips passing through Highway 1 and going to Steinwerder. On the second day, this number goes down to 60 trips. In the other direction, from Steinwerder to our Highway 1 area, we go from 90 to 81 trips.

These numbers are absolute numbers, and sometimes it is more informative to use percentages. To do so:

  • 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, next to Origin-destination type.

You can now see what percentage of trips start or go to a certain area.

Step 4.3: Learn how to compute travel times and change in travel times between different regions

Let’s look how travel times differ between Steinwerder and our Highway 1 area and vice versa and how they changed between the two days.

For this select Average travel time from the dropdown box in the CONFIGURATION panel, next to Origin-destination type.

Figure 3. Travel time analysis on the origin-destination page.

You should now observe the following:

  • Traveling from Steinwerder to Highway 1 took 25 minutes on the first day and 20.7 minutes on the second day.

  • Traveling in the other direction is slower around 30 minutes.

Let’s bookmark this analysis by clicking on the bookmark icon and naming it Step 4.3.

You can update bookmarks

When you loaded a bookmark before and try to create a new bookmark, the platform will ask you if you want to update the previously loaded bookmark.

If you do not want to update, but instead create a new one, select CREATE NEW.
