The London Cycling Design Standards (LCDS) were updated in 2014 by Transport for London. They represent a step change in the guidance available to traffic engineers and cycling campaigners in London.
The London Cycling Design Standards set out requirements and guidance for the design of cycle-friendly streets and spaces. It should be used by all those who shape the street environment through planning and street design, as well as engineers designing cycle-specific infrastructure. It forms one part of TfL's Streetscape Toolkit, and should be read in conjunction with the other constituent documents, including the Streetscape Guidance.
Introduction to the design standards and summary of key requirements
Guidance on network and route planning, land use planning and the Cycling Level of Service assessment
How to create attractive streets for cycling and balance user needs in making better places for everyone
Guidance on design of coherent, high quality infrastructure for cyclists on links, on and off-highway
Guidance on using and adapting junctions and crossings for safer and more coherent and comfortable cycling
Requirements on signing to support legible cycle routes and cyclists' general use of the highway
Key aspects of construction and maintenance that contribute to high quality cycle infrastructure
Guidance on planning and provision of fit-for-purpose, secure and well-located cycle parking
One essential element of the LCDS is the Cycling Level of Service (CLoS) tools to assess and score both exisiting and new infrastructure and junctions objectively. This gives a method for comparing design options and judging the value for money of new infrastructure plans.
