OSMnx · Find routes

Compute shortest paths across the Burjassot network, generate alternative routes, summarize a route’s metrics, and run many origin-destination pairs at once.

This walkthrough mirrors the Routing panel.

Before you begin

Download a drive network and add Edge Speeds and Travel Times (see Add edge attributes) so time-based routing works.

1. Pick origin and destination

In Routing, press the Select Source eyedropper and click a node in the viewport, then Select Target and click another. The node IDs appear in the panel.

Selecting source and target nodes with the eyedroppers.

2. Shortest path

Set Path Weight to length and press Shortest Path. The route is highlighted and its distance is reported. Switch the weight to travel_time to optimize for time instead.

A shortest path highlighted across the network.

Note

The elevation_impedance weight needs edge grades; see the Elevation tutorial.

3. Alternative routes

Set K (default 3) and press K Shortest Paths to draw several distinct alternatives between the same endpoints.

Three alternative routes between the same endpoints.

4. Route summary

Press Route Summary to report the active route’s length, travel time, mean absolute grade and rise.

Route Summary reports length, time and grade.

5. Batch routing

Set Random N (number of OD pairs) and Batch CPUs, then press Batch Routes to sample and route many pairs at once, reporting aggregate statistics.
