Create a selected link/region study

When creating a selected link/region OD study in iNode, you’ll first configure the core parameters that define what data is included and how results are generated. This step allows you to write your study name, select a study type, vehicle types, and the map framework used to represent the road network. These selections ensure your study is tailored to the specific traffic characteristics, analysis goals, and geographic context you want to evaluate.

To start a new study:

• Click on Create
• Write the name of your study under Study Name
• Select the vehicle type(s) to include in your analysis
• Select the map type to use as the underlying road network. iNode currently supports both Orbis and Genesis map types during TomTom's transition between platforms

Selecting your region

Available regions to you for study creation

The highlighted area(s) on the map represents the available regions to you for your study creation, which is determined and preset by your account access. They can range from a single area/segment, to a city/state or a country (countries).

Two ways of creating a Selected link/region study

1. Drawing your study areas
2. Using the search bar

1. Draw your study areas

There are two tools available to create or add a segment/region. They are:

1. Line tool
2. Polygon tool

1.1 Line tool - Creating a segment

The Line tool allows the user to draw a link on the map. To use this tool:

• Click on Add New on the left side of the map.
• Enter the name of the link.
• Click on the Line Tool in the top-left corner of the map.
• Zoom into the road section you want results for.
• A plus-shaped cursor will appear on the map, allowing the user to draw a link. When finished, the user can double-click to complete the drawing, and the road segments associated with the link will be selected.
• Accept the link.

After accepting the link, Select Exits/Entrances by Road Classes and Buffer Radius will appear.

Select Exits/Entrances by Road Classes allow you to specify which functional road classes (FRC) should be included in the results.

Buffer Radius determines the percentage of incoming and outgoing traffic to and from the selected route within the segments falling inside that radius for the chosen road classes.

For example, the user could select a 25 km radius with FRCs 0 to 4.

1.2 Polygon tool - Creating a region

This tool is designed to create a study to analyze the incoming and outgoing trip patterns related to a region.

The Polygon tool allows the user to draw a custom polygon on the map. To use this tool:

• Click on Add New on the left side of the map.
• Enter the name of the region.
• Select the Polygon tool in the top-left corner of the map.
• Draw a polygon on the map.
• Accept the region.

2. Use the search bar

Users can use the search bar to look up an address, name of the area/city/town, postal/zip code, etc. The app will zoom in on the selected location where you can draw your study area using line or polygon tool. If the searched name is associated with a geometry, you can also select that geometry as a region.

For example, if the user searches for an FSA (the first part of a Canadian postal code) like K1G, the area associated with that FSA will appear on the map and can be used as a region.

To do this:

• Add a new region.
• Enter the name of the region.
• Search for the FSA in the search bar.
• Accept the geometry
