OSMnx · Add edge attributes

Enrich the Burjassot network with the edge attributes that routing, statistics and orientation analysis depend on: lengths, bearings, speeds and travel times.

This walkthrough mirrors the Network Attributes panel.

Before you begin

Have a downloaded network active (see Download a street network). Projecting it first (Clean up the graph) is recommended.

1. Edge lengths

Press Add Edge Lengths to compute the geodesic length of every edge in meters. Fresh downloads already include lengths, but recompute them after any geometry edit.

Add Edge Lengths computes per-edge length in meters.

2. Edge speeds

Press Add Edge Speeds. Where OSM provides a maxspeed tag it is used; otherwise the Fallback Speed field (default 30 km/h) applies.

Add Edge Speeds with a fallback of 30 km/h.

3. Travel times

Press Add Travel Times to derive a travel_time attribute from length and speed. This unlocks time-based routing and isochrones.

Add Travel Times derives travel_time from length and speed.

4. Edge bearings

Press Add Edge Bearings to compute each edge’s compass bearing (0–360°), required by the orientation entropy and rose in the Statistics tutorial.

Add Edge Bearings computes per-edge compass bearings.

Next steps

With speeds and travel times in place, continue with Find routes.
