Create an Origin-Destination Analysis


This guide will show you how to easily create a basic Origin-Destination (O-D) analysis Project using StreetLight InSight. Our O-D Analysis is one of our most versatile Project Types because it allows you to understand trip volumes and flows between Origin and Destination Zones.
Note that this Project Type not only lets you analyze trips that pass through your Origin and Destination Zones but also trips that start and stop in those Zones. The ability to analyze trip flows, trip volumes -- whether trips are pass-through or not -- means that O-D analyses are useful assets when conducting weave analyses, internal-external studies, turning ratios, travel demand models, and more.

In this guide, we’re going to create an O-D Analysis for all the TAZs in Madison, WI. We want a traditional “full” matrix, where the Origin Zones are the same as the Destination Zones. This means that we’re looking at the true origin and destination of each trip - that is, where the trip actually starts and actually ends.

Keep in mind that while we’re walking through a specific example in Madison, you can use the flow described here to create O-D Matrices where the Origin and Destination Zones are different from each other, and where the Origin and Destination Zones are pass-through Zones road segments.

Step 1: Create your Zones

1a. Go to the Manage Travel Projects section by clicking the tab on the left. Then click “Add Zone Set.” Learn more about uploading or drawing Zones.

1b. After creating your Zone Set by either uploading or drawing, you’ll have a final chance to edit the names or borders of any Zones. To do so, click on the edit pencil icon next to the Zone before you save the Zone Set. Below is an example of a Zone Set that we uploaded for Madison Wisconsin.

Now you can see your Zone Set saved in your Zone Set library. As long as you haven’t used the Zone Set in a Project, you can edit it by clicking the edit icon in the Actions column. Within the Manage Zone Sets tab, you can also view, duplicate, and download shapefiles of Zone Sets.

Step 2: Create and Run an Origin-Destination Project

2a. Go to the “Create Projects” tab.

2b. Give your Project a unique name. For this example, we will name our project “Madison TAZ to TAZ OD.”

2c. In the “Select a Project Type” drop-down menu, select O-D Analysis. For this example, pick “Personal” for the type of travel and “Location-Based Services” data for our data source type. However, both of our data sources are available for an O-D analysis. Learn more about choosing your data source. You can type a description of the Project in the description box with any information you want to remember.


2d. All Zone Sets that are available for use in your account will appear in the “Available Zone Sets” box. (Note: Zones must be located within your designated subscription region.) For this example, we will select “Madison TAZs.” Select the Zone Set and then use the arrow buttons to add it to the Origin Zone Set box and the Destination Zone Set box. Since this is a classic O-D analysis, we will use the same Zone Set for both origins and destinations. However, you can also use different Zone Sets for each, and you can add multiple Zone Sets to each category.



2e. For any O-D project, you can click “Edit” to change the Data Period, Dates, Day Parts, and more.

When you click edit, a new window will pop-up that allows you to select the months of data you would like to analyze. There are many other customizable options, which you can select if needed.

2f. Click “confirm” and your Project will begin running.

Projects will take anywhere from a few seconds to a few hours to run, depending on their size and complexity. You can check on the progress of your project by looking in the “Running Projects” Tab. Once the Project is complete, it will appear in the “All Projects” tab and will become available for visualization in the Interactive Visualizations tab.

Step 3: Interactive Visualizations

3a. Click on the “Interactive Visualizations” section, and select your Project in the “Select a Project” box by clicking the title of your Project. Within the Interactive Visualization tool you can analyze results by type of day and time of day, by Origin Zone or Destination Zone you are visualizing, and more. Learn more about our Interactive Visualization tool.



Step 4: Download Metrics

4a. To download the Metrics and make your own analyses in Microsoft Excel, navigate to the Manage Projects section of StreetLight InSight. Then click the “All Projects” tab. Each of your completed projects should be visible. Click on the “Download” icon in the Actions Column.



4b. Select which files you want to download. For O-D projects, the most important download is the O-D .csv file. You can choose the other options as you see fit. Using the default settings is the quickest way to download your results.


4c. Open the compressed or “zipped” folder you’ve downloaded to view files you selected. You can manipulate these .csv files as you like. You will also have helpful README files that explain all the fields and files included in your downloads.

One of the common ways to analyze an O-D analysis is to create an O-D matrix. Learn more on how to create an O-D matrix.
