Colourful crossings

Read our open letter to the Mayor of London setting out our concerns about the safety and accessibility of colourful crossings.

A pedestrian crossing on a high street road is painted with stripes and dots in blue, purple, pink, green and orange.

Across the UK we are seeing more and more examples of ‘colourful crossings’, where the pedestrian crossing on the road is painted over with brightly coloured, often abstract, artistic designs. We have significant concerns about the safety and accessibility of these schemes.

We, together with 7 other disability organisations, have written an open letter to the Mayor of London setting out our objections to the engagement process for these schemes.

Open letter to the Mayor of London

Tuesday 28th September 2021

Dear Mayor Sadiq Khan,

Safety and accessibility of the Asphalt Art Project

We are a group of organisations representing many of the millions of disabled people who live in and visit London. We are writing to set out our significant concerns regarding the safety and accessibility of the ‘Asphalt Art Project’ (the installation of colourful patterns on road crossings) and our objections to the engagement process for these schemes.

Crossing the road safely is an essential part of negotiating our built environment and accessing our local community. The provision of safe crossing points affects everyone’s ability and desire to use their local streets, and this is especially crucial in enabling disabled people to make journeys as a pedestrian.

The past 18 months have seen a great number of changes made to the streetspace. As London adapted to the pandemic, the streets were transformed; with widened pavements, traffic calming measures, additional space for cycling, and more. Many of these changes were rolled out at pace, and implemented without due engagement with disabled people, and in many instances failed to identify negative impacts and mitigate against them. This has been thoroughly discussed and reflected upon (1), and in March this year TfL issued an updated version of their guidance (2) for Boroughs on Streetspace which stressed the importance of engaging with disabled people.

Given the many examples and opportunities for learning, it is disappointing to see another scheme repeating these patterns. The Asphalt Art Project demonstrates exactly what happens when meaningful engagement does not take place: it sadly results in schemes that are neither accessible nor inclusive.

In the accompanying pages to this letter, we have set out the impact these schemes will have on disabled people, the contradiction between these schemes and the welcome safety commitments made in Vision Zero, and our concerns regarding the engagement and Equality Impact Assessment processes for these crossings. We hope that your reply will address these issues, and will clarify whether London truly is open to everyone – including disabled Londoners and visitors.

Yours sincerely,

  • Transport for All
  • Alzheimer’s Society
  • RNIB
  • Guide Dogs
  • Scope
  • Age UK London
  • Inclusion London
  • London TravelWatch


1. Impact on disabled pedestrians

These designs create safety and accessibility concerns for some disabled people with particular impairments, as has been helpfully outlined in this letter from the Access Association (3). (We recommend reading their letter for full details of impacts on various impairment groups, and have outlined the major concerns below).

2. Vision Zero and road safety

Disabled pedestrians are already often more ‘vulnerable’ to collisions while using crossings than our non-disabled counterparts. For example, research suggests (6) that people with mild dementia, compared to people without dementia, have an increased likelihood of collisions, and this was associated with impairments in process speed and visual attention abilities. Therefore, any factors that could influence visual attention may increase risk for people with mild dementia crossing the road.

We welcome the Mayor’s zero tolerance approach to road traffic accidents, and have greatly supported Vision Zero as set out in the Mayor’s Transport Strategy (7) aiming for the total elimination of all deaths and serious injuries from London’s transport network by 2041.

We feel that the Asphalt Art project does not fit with the strategies set out in Vision Zero, particularly the point on Safe Streets; “ensuring safety is at the forefront of all design schemes”. With such major safety concerns raised, we cannot see how this project has been approved and implemented.


3. Exclusion

Asphalt Art is the signature project for the Mayor’s Let’s Do London Autumn campaign, designed to draw Londoners and visitors back to the city and celebrate all the vibrancy and diversity our culture has to offer.

We are concerned that, given the safety and accessibility implications, many disabled people will avoid the crossings and so will be persuaded away from these spaces altogether. Avoiding public space can lead to individuals becoming cut off from their communities, and facing even greater loneliness and isolation. The proportion of disabled people who report feeling lonely “often or always” is nearly four times that of non-disabled people (8), and we fear this project will exacerbate an existing issue and heighten the exclusion disabled people already face. This raises questions on who this project is intended to attract, and who London is open for.

It is almost impossible to meaningfully capture data on the people who aren’t present in public space because they are staying inside and avoiding the area. This means that any attempts to rigorously monitor this project’s impact on disabled people will fall short: how can we know who is missing?


4. Decision making and engagement

We have significant concerns about the scope and scale of meaningful engagement that has been undertaken with disabled people, and the extent to which this engagement has impacted on the design and implementation of the schemes.

The Public Sector Equality Duty (PSED) is clear that any potential impacts on groups must be considered at an early stage of the formation of a new scheme and to inform whether or not it goes ahead, rather than being added on at the end of the process.

In communications about this project, we have seen the claim that ‘this is a unique activity on this scale and there is a lack of information on potential equality impacts and mitigations’ (9). Whilst ‘colourful crossings’ may be a relatively new concept, the impact of bold patterned flooring on disabled people has been well researched and understood. In 2018 there were British Standards explicitly recommending against contrasting patterns on pedestrian surfaces, describing them as “disorientating or misleading” (10). We are therefore concerned as to why this, and other existing, evidence and research has not been included in the EqIA for this project. The commitment from many areas who are implementing these schemes to conduct user testing with disabled people once the artwork is in place is misguided, and demonstrates a lack of understanding of the negative impact this will have on many groups of disabled people such as those we work with.

(10) BS 8300-1: 2018: “Although visual contrast is very useful in enabling partially sighted people to perceive boundaries, bold surface patterns can be disorientating or misleading, and should therefore be avoided. The use of colour, patterning, lettering and imagery on pedestrian surfaces can be particularly problematic for people who are blind or partially sighted and people who have sensory/neurological processing difficulties.”
