Accessibility
The Accessibility panel measures reachability across the network: isochrones from a center, ego subgraphs around a node, and network-constrained clustering.
Note
Requires an active OSMnx graph.
Isochrones
| Control | Description |
|---|---|
| Center Node | Node the isochrones radiate from. |
| Times (min) | One or more trip-time thresholds. |
| Speed (km/h) | Travel speed used to convert distance to time. |
| Mode | Isochrone construction mode. |
| Buffer (m) | Buffer distance (shown only for the buffer-union mode). |
| Generate Isochrones | Builds the reachable-area polygons. |
Ego Subgraph
| Control | Description |
|---|---|
| Extract Ego Subgraph | Extract the neighbourhood subgraph around a node. |
Network-Constrained DBSCAN
| Control | Description |
|---|---|
| Cluster by Network Distance | Cluster nodes by network (not Euclidean) distance. |
