Selected Link/Region OD
iNode's Selected Link/Region OD is a study type that enables you to evaluate traffic flow along a specific road segment or an area within a road network. The algorithms calculate the distribution of inbound and outbound trips connected to the selected segment/region within a radius of 5 to 50 kilometers from the user-selected link; and from 5 to 10 km from the user-selected region.
2.1 Selected Link
Selected link analysis allows you to understand how trips are distributed around a specific road segment of interest. This provides valuable insights into corridor performance, the reach of a roadway, and the travel demand it attracts or disperses within the chosen distance band.
What it is
- Trips are traced based on whether they traverse certain road links (segments).
Designed for
Corridor & facility studies where you want to know who uses this road and where they come from/go to, such as:
- Corridor diversion or bypass analysis.
- Toll road or managed lane usage.
- Bridge/arterial bottleneck impact.
- Safety and congestion management at specific links.
Output
- Number of trips that cross the selected link(s).
- Trip counts of incoming and outgoing segments
2.2 Selected Region
Selected region analysis allows you to understand how trips are distributed around a specific region of interest.
What it is
- Trips are filtered based on entering, exiting, or passing through a user-defined area (polygon).
Designed for
Impact & neighborhood-level studies where you want to know what trips are generated by or attracted to an area:
- Stadium/event center traffic (inflow and outflow).
- Development impact studies (new mall, office district).
- Environmental studies (sensitive areas, residential cut-through).
- Border crossings (who crosses into a jurisdiction and from where).
Output
- Trips entering/leaving the area
- Trip counts on the segments coming to the area and leaving the area
- Alternative routes
