The Origin-Destination tool visualises travel behaviour between and within selected areas.
To get the results in Origin-Destination, you’ll need to select at least 2 zones.
When you’re done with selecting time periods and path selections you can start the analysis. Just keep in mind load times vary depending on the length and quantity of your paths, and extent of your date range/s.
When the results are loaded, the map will show which paths are used the most. This is shown by the thickness and colour of the edges. This is also known as the Edge Usage Rank or EUR.
Hover over the lines to see a ratio of the road volume on the edge compared to the most travelled edge. On a scale of 0-100, 100 represents the most used and 0 is the least used. There is also a composition that shows the breakdown of vehicle types.
Try using the Origin-Destination tool to understand travel times, trip volumes, hourly breakdowns, and Edge Usage Ranking (EUR) across Sydney. We'll see how people travel between Manly, Macquarie University, and the Sydney Harbour Bridge.

The Origin-Destination tool allows you to view travel behaviour between and within selected zones.
In Origin-Destination, you'll notice that where the Path Selection panel is has now turned into the Zone Selection panel. There are four ways that you can select different zones. The first one is by inputting a polygon WKT file, the second is by selecting a path, the third is by creating an organic polygon zone, and then the fourth is by clicking a pre-selected boundary. A pre-selected boundary is things like postcodes, suburbs, SA2s, SA3s, SA4s.
To run an Origin-Destination analysis, you need at least two or more zones selected.

In the Results panel, you'll see the times and dates that you have selected as well as the ability to filter by different vehicle types - this includes car, HCV, and All. It'll then list the different origins and destinations that you have selected, and this will give you information, such as travel time, the trip distribution, and the distance.
There are also graphs that you can view information about travel volumes as a percentage.

You'll also notice that on the map pathing will appear. This gives you an indication of what were the most used legs to get between different zones that you have selected. The darker and thicker the line, the more people use those routes.
Hovering over each of these edge IDs, gives you an idea of the percentage of all trips and an Edge Usage Ranking score. The Edge Usage Rank is a ratio of the road volume on this edge as compared to the most travelled edge - 100 being the most used and zero being the least.

For example, if the most travelled edge has 4,000 vehicles during the time period that you've selected, and the hovered edge has 1,000 this is 25% as much as the most travelled edge and therefore has an Edge Usage Rank of 25.
The composition shows you a breakdown of all the vehicles that travelled through this edge or selection by vehicle type.
