The Dask at Hand: Using Dask to Speed up the High Quality Transit Areas dataset for the CA Open Data Portal.
Tiffany Chu
Where are CA’s frequent, high quality transit corridors? The CA Public Resources Code defines it, but it requires continued access of the General Transit Specification Feed (GTFS) data and fairly complex geospatial processing. The Integrated Travel Project within Caltrans tackles this by leveraging the combined powers of Dask and Python to make this dataset publicly available and updated monthly on the CA open data portal.
