Calibrating with StreetLight 2017 AADT

This tutorial will walk you through how to run a Calibrated Project using StreetLight’s 2017 AADT Metrics. Our Calibration Feature is a great tool for users who want to get estimated counts rather than our StreetLight Index, learn more about our Index. Calibrating with 2017 AADT is only available to users who have a Gold or Platinum subscription. If you would like to Calibrate with your own count data learn more. A user can use 2017 AADT to calibrate the following Project Types: Zone Activity Analysis, O-D Analysis, O-D with Middle Filter Analysis,

O-D to Preset Geography and Segment Analysis. To learn more about how to create a Calibrated analysis, check out our solutions guide [link solutions guide].

For this tutorial, we will go step-by-step to help you set up your Calibrated Project using 2017 AADT Metrics. Unlike Calibrating your Zone Set with “My Counts,” you do not need to set up a Calibration Zone Set with trip counts prior to creating a Calibrated project.

Important Information to Note Before Running your Project:

For the “Calibrate with StreetLight AADT” option, StreetLight InSight will first generate 2017 AADT for any Pass-through Zones specified as Calibration Zones in the Project setup process. These AADT values will be the input for estimating counts as though you had entered them as your own counts. This is the main difference between Calibrating with StreetLight 2017 AADT versus Calibrating with your Zone Counts. Learn more on calibrating with your own counts.

Creating a Calibration Project with 2017 AADT

Step 1: Create a Zone Set where all Zones are both Pass-through and Bi-Directional. To learn more on creating Zone Sets. 

Step 2: Go to the “Create Projects” tab and create either a Zone Activity Analysis, O-D Analysis, O-D with Middle Filter Analysis, O-D to Pre-set Geography, or Segment Analysis. Select your Travel Type and Data Source. Next, under “Calibration Type,” choose “Calibrate with StreetLight AADT 2017” from the drop-down menu when setting up your project.

Step 3: When you choose one of the “Calibrate Type” options, a new Zone Set category window will appear allowing you to select a Calibration Zone Set. Add your Calibration Zone Sets as you would any other set.


Step 4: Confirm and Run your Project

Step 5: Once the Project is marked as “Complete” on the All Projects tab you’ll be able to download and visualize the results. When visualizing and working with the downloaded .csv files, look for the “Calibrated StL Index” value. You’ll see this value right next to the “StL Index” values that are generated for every project. This “Calibrated StL Index” value will reflect an estimated trip count for your selected Zone or O-D pair based on the Calibration Zones included in your Project.
