LTNs: Streets

This data shows whether each street is either:

• An LTN / no-through traffic
• A through-route (i.e. rat-running possible)
• A through-route, but with traffic calming

The data shown here is the result of automated analysis of OpenStreetMap data.

This work is experimental at present, with known bugs. We continue to refine the analysis.

A maximum of 2,000 results are returned within the supplied bounding box. Geometries are simplified to 5 decimal places.

Coverage is currently the UK and Ireland.

Example

Example which retrieves streets marked as LTN/rat-run/traffic-calmed in an area of central Cambridge.

Request parameters - required

bbox comma separated bounds: west,south,east,north

Boundaries of the data in degrees longitude / latitude.
When a censuscode has been provided this parameter is not required and is ignored.

Request parameters - optional

censuscode char (9)

A string of exactly nine characters containing only digits and letters A-Z. Identifies a geographical region matching the corresponding census_code in the OS Boundary Line database (GB only). Codes for regions outside GB have been auto-generated by CycleStreets and no assurances can be made about how constant they remain over time. When provided any bbox parameter is ignored.
Browsers given this link will force a download using a filename of the form: LTN streets - <human readable area name> (<census code>) - CycleStreets.geojson

zoom int/float (number between 1 and 19)

The map zoom at which the photo location was set (which helps us determine the most appropriate lines to show).

Response

JSON structure as per example above.

Error response

JSON object containing an error key and a text string.

Example error (text string may vary):

{
    "error": "No bbox parameter was supplied."
}
