TfL has recently published an extensively revised and updated set of London Cycling Design Standards (LCDS, 2014). They represent a significant step towards the achievement of consistent highway designs offering safe and convenient cycling conditions on all London's roads. Included in the LCDS is a Cycling Level of Service (CLoS) assessment procedure and an associated Junction Assessment Tool (JAT), both of which offer scoring schemes that aid the assessment of cycling safety and convenience in new highway designs. However, neither the CLoS procedure nor the simpler JAT appears to be in regular use by TfL to evaluate the designs for proposed new and upgraded junctions. Will you ensure that an assessment based on one or both of these useful metrics is used by TfL for future highway designs and will you set minimum assessment scores that should normally be achieved in such designs?

TfL updated the London Cycling Design Standards (LCDS) in 2014 to provide a comprehensive guide to planning, designing and delivering high quality infrastructure for cycling through highway schemes.

TfL promotes the use of the Cycling Level of Service (CLoS) and Junction Assessment Tool (JAT) on all highway schemes.  TfL trains people in each tool's use during design development, particularly at the analysis and option development stage.

The CLoS and JAT are designed to aid decision making when multiple options are available in order to identify the best solution for cyclists. The needs of other road users and pedestrians are also assessed at this stage to ensure the delivery of a balanced scheme. The use of these tools does not substitute for other important aspects of the design process, such as taking into account the specific issues and constraints at the location being assessed, establishing and meeting agreed project outcomes and responding to all user needs.

The JAT, for example, is used to analyse potential cycle movements through a junction in a way that promotes discussion between designers about the best ways of addressing identified design issues. While scores may be useful in comparing options, the creative process to generate the optimal design for a given context is far more important. CLoS has been used to great effect on several high profile schemes, helping to highlight deficiencies and identify design solutions.

CLoS and JAT are tools to improve quality but they are not currently used to benchmark performance. Therefore, neither tool includes a minimum benchmark score at present, although this is not ruled out for the future. If analysis of the impacts and value show this would be beneficial, TfL may consider this.
