Freedom of Information request - Locations of permanent traffic signals
Request ID: FOI-1595-2223 Date published: 12 October 2022
You asked
Dear Transport for London,
Please provide a CSV with an up-to-date list of the junctions and crossings controlled by permanent traffic signals managed by you. In each case, please include the following information about each junction/signal:
- Signal ID
- Borough ID and name
- Site type and description
- Installation date
- Geo coordinates of the junction or crossing
- Description of the location
- Whether the location is on the TLRN
- The number of different Street Types at the location
- Street Types of the streets making up the location
In the case that information on the Street Type isn't available at a given location, please still provide as much info as possible on the signal's location, etc.
I have based this request on an FOI from 2019:
https://tfl.gov.uk/corporate/transparency/freedom-of-information/foi-request-detail?referenceId=FOI-3461-1819
Please note two things though:
1. I am requesting a complete list of signals, regardless of street type, and including Bromley 2. The CSV provided as a reply to that request included many Street Type cells filled with "#REF!" toward the end of the document, which implies that it was incorrectly exported from an Excel spreadsheet. It would be helpful if the CSV produced this time could be free from such errors.
