Concepts

Background reading: how OpenDRIVE describes a road network, and why the editor behaves the way it does. Nothing here asks you to click anything — read these pages when you want to understand, not when you are in the middle of a task.

• OpenDRIVE in Five Minutes — reference lines, lanes, sections and links
• Road Geometry — lines, arcs, spirals and Bezier curves
• Anatomy of a Junction — connecting roads and lane connections
• Linkage: What the Editor Links for You — automatic and manual links
• Georeferencing — local metres and positions on the Earth
• Objects and Signals — two ways to describe road markings
