We are the first in the state to implement a specially designed Convoy Vehicle to assist with onsite speed management, this will allow all road users passing through the works area to be escorted at a controlled speed. This can also be used with eBOOM and eSTOP devices.

Where normal traffic control arrangements are not feasible because of restricted roadway width, and diversion is impracticable, convoy working may be used. In this method, traffic is brought to a halt in advance of the works area and is then led slowly in single file at a controlled speed past the works area by our appropriately signed works convoy vehicle. If convoy working is to be used, the correct authority will need to be consulted well in advance of the works being undertaken.

Where there is little or no safety zone clearance, traffic speeds past the working area must be reliably reduced to around 40 kmh or less as per an agreed safe method of working imposed on the site. A risk assessment of the actual work activity and the effects of convoy working on the workforce and road users must be conducted in order to determine whether this system is appropriate for the particular task and location.

Convoy working may be used during the hours of daylight or darkness and can be used on:

• Single carriageway roads where traffic travels either in a single direction or in alternating directions;
• Individual carriageways of two-lane all-purpose dual carriageway lanes where traffic travels in one direction only and works have reduced the traffic lanes to single lanes;
• Carriageways during resurfacing operations when it is considered necessary to ensure traffic speeds are low.
