pyxodr 0.1.3

Read OpenDRIVE files.

pyxodr

Read OpenDRIVE files into a class structure that represents road objects as arrays of (x,y,z) coordinates rather than parameterised functions.

This class structure implements an API which should act as a middle layer between OpenDRIVE files and other applications, used to create road networks from their coordinates.

               

Installation

Install with pip:

pip install pyxodr

Testing

Testing is done on the OpenDRIVE example files. I have not included them in this repository as ASAM requires you enter your details to access them, so I assume they don't want them publically distributed through any means other than their own website. You can access them here.

You can also test on the networks for the OpenSCENARIO example files, obtainable here.

Once you've downloaded these files, create an example_networks subdirectory under tests and place them there.

and then you should be able to run the (Pytest) tests as normal:

Note: with version 1.7.0 of the OpenDRIVE spec, the Ex_LHT-Complex-X-Junction file throws a connection position ValueError on plotting with this module. I think this is due to a mistake in the file; older versions of this file work without throwing an error, and I believe that the direction of the reference line of road id==3 was reversed without swapping the corresponding contactPoint(s) - e.g. in road id==34, where it is listed as a successor with contactPoint=="start" despite the reference lines now traveling in opposite directions. If I'm incorrect about this and this is an error with the code, please raise an issue.

TODO

Large components of the OpenDRIVE spec are not currently supported, including:

• Super Elevation / Road Shape (8.4.2 & 8.4.3)
• Road surfaces (8.5)
• Road markings (9.6)
• Junction groups (10.7)
• Objects (11)
• Signals (12)
• Railroads (13)
• elementDir / elementS for road & junction linking.

Some of these will be supported in the future. Pull requests implementing (or partially implementing) any of these are welcome. Additionally if you find anything else unsupported by this repo which is not covered by the above list (and there will be lots), please raise an issue.
