FOI request detail

A13 (East London) average speed camera system (distances between cameras)

Request ID: FOI-0275-1718
Date published: 17 May 2017

You asked

There is an average speed camera system on the A13 (East London). The system records the time each vehicle was at each camera and, by knowing the distances between cameras, the average speed of each vehicle in each section can be calculated. My FOI question is: What are the official measured distances between each pair of cameras within the A13 average speed camera system? (These distances should be minimum distance that it is possible to travel between each pair)
