Some sites cannot be controlled by portable signals alone. Long single-lane sections, poor visibility, steep gradients, multiple side roads and accesses, tracked plant crossing the road, or works that move along the carriageway all need people making decisions in real time. That is what convoy working and stop-go control are for.
Convoy working uses a lead vehicle to escort groups of traffic through a single-lane or restricted section at a controlled speed. Stop-go working uses operatives with boards, in radio contact, releasing traffic alternately from each end. Both are delivered by operatives who hold the tickets for the road type they are working on, working to a designed arrangement rather than improvising at the kerb.
Pedestrian management sits alongside it. When a footway is taken out of use, the people who used it still have to get past your works — including wheelchair users, people with pushchairs and visually impaired pedestrians. We design and install signed, physically separated routes with the right width, tapping rails and crossing points, and keep them continuous through every phase.
Professional help matters here more than anywhere, because these arrangements depend on human judgement in a live carriageway. Untrained people waving traffic through is how incidents happen. Trained operatives working to a drawing, with defined communication and defined stopping points, is how a job runs for weeks without one.
