Calibrate Using Single Factor with StreetLight AADT

This guide will walk you through how to run a Calibrated Project using "Single Factor with StreetLight AADT."* 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. If you would like to Calibrate with your own count data learn more. A user can use Single Factor with StreetLight 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. Learn more about how to get estimated counts through StreetLight InSight.

For this guide, we will go through how to set up your calibrated Project using StreetLight's AADT Metrics. Unlike Calibrating your Zone Set with “Single Factor User-provided Counts” you do not need to set up a Calibration Zone Set with trip counts prior to creating your Project.

*Subscriptions from before January 2019 may or may not have access to StreetLight's AADT Metrics.

Note: For the “Single Factor with StreetLight AADT” option, StreetLight InSight will first generate 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 "Single Factor with StreetLight AADT" versus Calibrating with "Single Factor User-provided Counts". Learn more on calibrating with your own count data.

Creating a Calibration Project using "Single Factor with StreetLight AADT"

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

Step 2: Go to the “Create Projects” tab and set up your Project with the following Parameters:

  • Project Type: "Zone Activity Analysis," "O-D Analysis," "O-D with Middle Filter Analysis." "O-D to Pre-set Geography," or "Segment Analysis" 
  • Type of Travel: "Personal" or "Commercial"
  • Modes of Travel: "All Modes"
  • Data Source: "Location-Based Services with Pass-through" or "Navigation-GPS"
  • Calibration Type: "Single Factor with StreetLight AADT"

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 Set by selecting it from the “Available Zone Sets” tab and clicking the arrow under “Calibration.”

Step 4: Choose your Calibration Period

Step 5: Click "Confirm"

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.
