Traffic Signs Manual Chapter 8 - Part 1: Design provides guidance for those responsible for the design of temporary traffic management arrangements, which should be implemented to facilitate maintenance activities or in response to temporary situations.

It is structured to reflect the design process for temporary traffic management, from the initial broad brief to details of signing provision. It raises the principal issues that need to be considered in temporary traffic management design and provides advice about their resolution.

Chapter 8 is intended to provide a standard of good practice for the signing and marking of obstructions as well as for the temporary traffic control necessitated by such obstructions of the highway. The standard described is a minimum, which should always be achieved.

Traffic Signs Manual Chapter 8 - Part 1: Design contains:

• Advice relating to traffic safety measures
• Identity and location of the traffic signs needed to guide road users, including pedestrians
• Identity and location of the traffic signs needed to guide road users safely past obstructions in temporary situations
• Documents dealing with the design of temporary traffic management arrangements on single carriageway roads and dual carriageway roads
• Illustrated design guidance, including sample plans.

All authorities, bodies and organisations responsible for all types of roads, to which the public have access, are advised to comply with the requirements of Chapter 8 (Parts 1 and 2), a condition of contract in the case of works carried out on their behalf.
