  • the ATCS 10 When the ATCS 10 is installed it is able to operate autonomously to clean the wall 18 or other surfaces of the tunnel 16 while the tunnel 16 is fully open to traffic without the need for an on-board human operator, on-site human supervision or the erection of temporary safety barriers. Therefore embodiments of the ATCS 10 enable the cleaning of a tunnel 16 without impacting on traffic flow and without the need for human operators to be within the working tunnel.
