Areas are chosen based on crashes, presence of schools and other neighborhood amenities, and community support. The treatments include a mixture of markings, signage, and speed humps.

Freshness

The publisher's promise

How the agency that publishes this data says it keeps the data current.

FreshNo automatic refresh

Automatic refresh

No scheduled refresh runs for this dataset, and a refresh you ask for on this page is refused.

  • Our catalog lists this dataset without keeping a copy of its rows, so the automatic queue has no copy to refresh. This fence refuses a refresh you ask for on this page.
  • This dataset needs a copy method that the automatic queue does not run, such as a bulk export of a very large table. This fence refuses a refresh you ask for on this page.
