plans to remove this requirement have been considered. In 2016, an 'active mobility' system was installed in the tunnel to monitor and actively manage tunnel usage. The system used computer vision to count and measure the speed of bicycles and pedestrians, and displayed messages on electronic signs to encourage considerate behaviour. The system (also installed in the Woolwich foot tunnel) displayed two messages: "No cycling allowed" (in red text) during busy periods, and "Please consider pedestrians" (in green text) during quiet periods, aiming to make urban shared spaces safer and more pleasant to use for all. The shared spaces trial was supported by Greenwich council but Tower Hamlets refused permission to update the bylaws and the sign system was discontinued; while some cyclists do ride in the tunnel, cycling is still not permitted. With a continuing impasse in updating the bylaws, FOGWOFT disbanded in March 2021. In January 2023 Tower Hamlets Council considered a motion expressing continuing concern about cycling in the Tunnel.
