Requirements for ITS deployments in the UK

ITS Standards

The design, specification and use of Intelligent Transport Systems in the UK (verify specific requirements for devolved authorities in Wales, Scotland and Northern Ireland) are required to comply with a range of requirements, a large proportion of the sources for these are given below. Links are provided to each seperate website for the complete selection of documents provided by each organisation, and where possible, we will be adding direct links to individual items where relevant in an ITS context.

The Traffic Signs Regulations and General Directions

This is the legal framework used for signs and roadmarkings in the UK. Traffic signals and indicators fall under this statute.



TSS Plans Registry

Equipment specifications, drawings and procedures

The Design Manual for Roads and Bridges (DMRB)

An Overview Of Major Technologies Used To Control And Manage The Highway Network

National Highways specifications and procedures for the design, construction and maintenance of all aspects of the Strategic Road Network. Also used by local highway authorities for high-speed roads and some aspects of urban infrastructure.



Standards for Highways (DfT)

A range of Highway related requirements

These include Contract for Works (MCHW), Interim Advice Notes (IANs) and Technology Management and Maintenance Manual (TMMM)



Local Transport Notes (DfT)

Traffic management guidance for local authorities

Local transport notes (LTNs) summarise the latest and most important ideas about traffic management issues and provide guidance for local authorities.



Traffic Advisory Leaflets (DfT)

Information leaflets about using traffic equipment

Traffic advisory leaflets (TALs) provide information and guidance for using traffic equipment and implementing traffic regulations and policies.
