City of Austin Work Zone Data Exchange (WZDx) Feed

Scripts that support publishing work zone location data to a geojson feed specified by USDOT called WZDx.

The json feed is available here.

A tabular version is also available here.

These work zones are currently being shown on the CTXGO website (managed by TxDOT).

Data Sources

AMANDA Temporary Use of Right of Way (TURP) Permits

AMANDA is software used by the city to manage permitting. This data source is only for the TURP permits that are issued.

TURP permits can close entire roadways or a few lanes.

AMANDA Excavation Permits

Excavation permits frequently require a lane closure in at least one direction. This feed only includes those excavation permits issued for the roadway or those next to the roadway.

Coordinate

City permits are tracked in a software platform called Coordinate. One feature of this platform allows for work zones to be "activated" by permittees. This information is included in the work zone data feed through the worker_presence object.

Validation

The schema_validation.py script will check a small subset of work zones in local copy of work zone datafeed's geojson against the schema.

To validate:

1. Run the feed, with the local-file argument: python data_sources/amanda_closure_publishing.py --local-file wzdx_output.geojson
2. Then run the validator python validation/schema_validation.py
3. You should get ✅ data sample passes schema validation or an error message if something is wrong.

Deployment

Docker

It is recommended to run this script using the docker container. You can build it using:

Note, if you are on Apple Silicon you may need to add --platform linux/amd64 to get GDAL to install correctly.

docker build . -t atddocker/dts-work-zone-data-feed:local

Then, run it with an env_file created using the env_template.

docker run -it --env-file .env atddocker/dts-work-zone-data-feed:local /bin/bash
python data_sources/amanda_closure_publishing.py
