Editing a Zone Set

This guide will walk you through how to review and edit a Zone Set after you have saved it in StreetLight InSight. This article consists of three parts: editing a Zone Set overview, editing a Polygon Zone, and editing a Line Segment Zone. Learn more about generally drawing and uploading Zone Sets.

Heads Up:

There are a few parameters that will limit your ability to edit a Zone Set. We will go into depth on these parameters later in this article, but keep in mind that the following two parameters will affect when you can and cannot edit a Zone Set.

  • Parameter 1: If your Zone Set has already been used in a project.
  • Parameter 2: One of your Zones has over 250 points--this will be more common for complex Polygon Zones, like very detailed city, county or state boundaries.

Section One: Editing a Zone Set (Overview)

Finding and Opening a Zone Set

Step 1: Navigate to the “Manage Travel Projects” tab section of your StreetLight InSight account, which is located in the upper left-hand corner under the menu icon.

Clicking the edit button will display a modal listing each Zones in the Zone Set. In this modal you will be able to edit individual Zones and also rename the Zone Set.

If your Zone Set has already been used in a project, then you can only change the name of a Zone Set. You will not be able to edit any other aspects of that particular Zone Set. 

 

Available Options from the Edit Zone Set Screen

Remember, every option after "Option 1: Renaming a Zone Set" is only available for Zone Sets that have not been used in any Project.

Option 1: Renaming a Zone Set

Step 1: Click “Edit” at the top of the Modal

Step 2: Rename your Zone Set

Step 3: Click “Rename”

Step 4: If that’s all you would like to change click “Close” at the bottom of the modal.

Note: Typically the Zone Set will show up as “Processing” in your Zone Set list after you have changed the name. While the Zone Set is processing you cannot use it in a Project.

Option 2: Adding a New Zone

You can either add a new Zone by drawing or uploading.

Step 1: Click either Draw New Zone, Upload Shapefile, Upload Excel

Step 2: You will be taken to the regular Modal to create a Zone. Add your Zones. Learn more about uploading or drawing Zone Sets.

Step 3: Click “Save”

Step 4: To return to your existing Zone Set click “ View Zone Set List”

After you click “Save” your new Zones will appear in your Zone Set list.

Option 3: Edit Existing Zones

In this section of the modal, you will be able to edit the Individual Zones in your Zone Set. You will be able to:

  • Click the “Set to Bi-Directional” button to set all of your Zones to Bi-directional. Learn more about directionality.
  • Click the icon to edit an individual Zone in your Zone Set.
  • Click the  icon to copy an individual Zone in your Zone Set
  • Click the icon to delete an individual Zone from your Zone Set.
  • Click the  icon to reverse the direction of an individual Zone in your Zone Set.*

*Only available when editing Line Segments.

 

How to Edit an Individual Zone in a Zone Set

Here we will talk about how you can generally edit an individual Zone. If you would like to learn how to specifically edit a Line Segment Zone or a Polygon Zone continue to sections two and three of this article.

Step 1: Click the pencil icon. Then you will be taken to a window where you’ll be able to perform the following updates:

  • Completely redraw the zone by clicking the “Draw Polygon” button and then clicking directly on the map to create your new Polygon. You can also delete your new Zone by clicking the trash can next to the “Draw Polygon” button.

  • Update the Zone Name and Zone ID.
  • Change whether a Zone is Pass-through
  • Add direction--Learn more
  • Change whether a Pass-through Zone is bi-directional
  • Add calibration--Learn more

Step 2: Click “Save” and all of your changes will be made to your existing Zone Set.

 

Step 3: To return to your existing Zone Set click “ View Zone Set List”

Note:

  •  If you Have Used Your Zones in a Project: Once you have used a Zone Set in a Project, you will no longer be able to edit the Zones within the Zone Set. The only thing you can change is the name of the Zone Set. If you are renaming a Zone Set you must click the “Rename” button to actually save the new name.
  • If your Zone contains more than 250 points: When you have a Zone that contains more than 250 points you will not be able to edit or replace the Zone. If you have not used it in a project, you will still be able to rename your Zone, Change whether your Zone is Pass-through, and Change the Zone ID.

Zones with over 250 points are more common with Polygon Zones--especially if you have uploaded a complex geometry.

 Pro Tip:

  • If you would like to edit your Zone Set after you have used it in a project, you can copy your Zone Set and then edit the duplicated version.

  • When reviewing and editing your Zones, click the OpenStreetMap dropdown in the upper right-hand corner of your map. This will display the OpenStreetMap layer, which is used to lock trips to the underlying road network. The OSM lines will help you confirm whether your gates are accurately capturing traffic. You can pick Vehicle, Pedestrians, Bicycles, or a combination of the three. 

Section 2: Review and Edit a Polygon Zone

This section will show you how to review and edit Polygon Zones and Zone Sets. Polygon Zones can be used for all road types or areas, and are our most basic type of Zone. They capture activity within a defined area and can be used across all project types. Polygon Zones can either be drawn or uploaded from a shapefile, Learn more on drawing or uploading a Polygon Zone Set.

When a polygon Zone is added to StreetLight InSight, a number of items are stored with the Zone:

  • The original Polygon shape
  • Whether the Zone is pass-through or not
  • Any direction defined in degrees
  • Whether the Zone is bi-directional
  • Calibration data

Review and Edit a Polygon Zones

When reviewing and editing a Polygon Zone, you will follow the same initial steps in section one. As long as your Zone Set was not used in a project or the Zones do not have more than 250 points, you will be able to edit the following aspects of your Polygon Zones.

Step 1: Click on the pencil icon to edit each individual Zone in your Zone Set, and then you will be taken to the modal pictured below. There you will be able to edit a specific Polygon Zone in your Zone Set.

Step 2: Edit your Zone Set.

For a polygon Zone, you will be able to edit various Zone components:

  • Completely redraw the zone
  • Update the Zone Name and Zone ID
  • Change whether a Zone is Pass-through
  • Add direction--Learn more
  • Change whether a Pass-through Zone is bi-directional
  • Add calibration--Learn more

Note: You cannot edit a Zone boundary after you have saved it, you must completely redraw it if you would like to change the boundary.

Step 3: Click “Save” at the bottom of the modal.

Section 3: Review and Edit a Line Segment Zone

This section will show you how to review and edit line segment Zones and Zone Sets in StreetLight InSight. Line segment Zones represent portions of the road network. They can be used to capture traffic traveling along roads of all types, including highways, freeway ramps, and city streets. Once line segment Zones are added to StreetLight InSight as a Zone Set--either by drawing or uploading a line shapefile--they can be used in various Project Types, including O-D Analysis, Zone Activity Analysis, Segment Analysis, and Traffic Diagnostics.

Initially, follow the steps in section one of this article. Click on the pencil icon to edit each individual Zone in your Zone Set, and then you will be taken to the modal pictured below. There you will be able to edit a specific Line Segment Zone in your Zone Set.

When a line segment Zone is added to StreetLight InSight, a number of items are stored with the Zone:

  • The original line shape.
  • The start point
  • The end point
  • A start gate: a polygon Zone created at the start point drawn perpendicular to the line. This gate along with the end gate is used in Segment Analyses and Traffic Diagnostics projects.
  • A middle gate: a polygon Zone created at the midpoint of the line drawn perpendicular to the line. This gate is used in O-D type analyses.
  • An end gate: a polygon Zone created at the end point drawn perpendicular to the line. This gate along with the end gate is used in Segment Analyses and Traffic Diagnostics projects.
  • Direction information.

Reviewing and Editing Line Segment Zones

When reviewing and editing a Line Segment Zone, you will follow the same initial steps as section one. As long as your Zone Set was not used in a project or the Zones do not have more than 250 points, you will be able to edit the following aspects of your Line Segment Zones.

Step 1: Click on the pencil icon to edit each individual Zone in your Zone Set. You will be taken to the modal pictured below, and there you will be able to edit a specific Ling Segment Zone in your Zone Set.

Step 2: You’ll have the option to edit the Start, Middle and End gates associated with each line segment. Be sure to choose which gate you wish to edit.

There are a few ways to edit each gate associated with your line segment:

  • You can adjust the location of the gate, by clicking the “Draw Polygon” button and then drawing it with your mouse.

  • You can redraw the direction of the gate by clicking the “Draw Direction” button.

On top of being able to edit your gates, you will also be able to:

  • Update the Zone Name and Zone ID
  • Change whether a Zone is bi-directional
  • Add calibration--Learn more

Note:

  • You can adjust whether the direction for the line segment is uni-directional or bi-directional on any of the gates, but the setting applies to the entire segment and all three gates.
  • We recommend making manual edits to line segment Zone Sets only once the entire Zone Set has been saved. Changes made to existing Zone Sets are saved immediately. Changes made to new Zone Sets are only saved once the entire Zone Set is saved.
