National Sector Scheme 12 (NHSS 12) in the UK is a set of guidelines and specifications designed to ensure that organizations involved in temporary traffic management on UK roads meet consistent quality standards. It is part of a series of sector schemes recognized by the highway authorities and overseen by the British Standards Institution (BSI). NHSS 12 is divided into several parts, each addressing different aspects or types of roads:
12 A/B
NHSS 12A/B:
12A/B high-speed traffic management works refer to specialized traffic control operations conducted on high-speed roads, such as motorways and dual carriageways, to ensure the safety of both road users and workers during construction, maintenance, or emergency activities. These works involve implementing advanced traffic management strategies, including lane closures, contraflows, buffer zones, and the use of crash barriers and vehicle-mounted attenuators to mitigate risks in high-speed environments. Additionally, clear and strategically placed signage, variable message signs (VMS), and speed reductions are crucial to informing and guiding drivers through affected areas. The “A” category typically addresses permanent solutions, such as installing or maintaining infrastructure, while “B” focuses on temporary measures during active works. Rigorous planning, compliance with legal and safety standards, and skilled personnel are essential for minimizing disruption and maintaining high levels of safety on these high-speed routes.
12 C
NHSS 12C: Focuses on mobile lane closures for high-speed roads, which involve moving operations that may require temporary traffic control features.
12 D
NHSS 12D:
12D traffic management refers to a system of temporary traffic control used primarily in construction, maintenance, and utility works to ensure the safe and efficient movement of vehicles and pedestrians while work is carried out on or near roadways. It involves implementing measures such as lane closures, detours, speed limit reductions, and the deployment of traffic controllers to manage flow and ensure safety. The design and operation of these measures are guided by strict regulations and standards to minimize disruption and protect workers and the public. Proper planning, signage, and communication are key to successful 12D traffic management, ensuring that the impact on road users is minimized while maintaining a safe environment for the workforce.
