maliput_malidrive

Description

maliput_malidrive package is a Maliput backend implementation. Its underlying format specification is based on OpenDRIVE format. Allowing the users to load a road network out of a XODR file description.

Please go to XODR Parser capabilities for further information about OpenDRIVE’s parser.

Note: For full information about Maliput please visit Maliput Documentation.

Resources

maliput_malidrive provides several map resources at maliput_malidrive/resources. These resources are:

• XODR files for describing different road networks using OpenDRIVE format specification.
• YAML files for describing maliput’s road network information of type: Range Value Rules, Discrete Value Rules, Traffic Lights, Phase Rings, Intersections, etc.

Resources are installed natively, so the users are able to use them for their own interest. In order to get the installation path check the environment variable: MALIPUT_MALIDRIVE_RESOURCE_ROOT.

API Documentation

Refer to Maliput Malidrive’s Online API Documentation.

Examples

Getting Started page is a good place for starting to see Maliput’s capabilities and how to use a Maliput backend for getting a road network.

• maliput_malidrive’s applications: This package provides some applications to validate a XODR file. See maliput_malidrive’s tutorials.
• maliput_integration: Concentrates applications created for maliput. See maliput_integration’s tutorials. These applications allow to select maliput_malidrive as the backend.
