London Detour research, prompt cards, public touchpoints, and prototype testing

London Detour

Testing a multi-touchpoint service to shift tourist behaviour towards discovering lesser-visited, more authentic sides of London beyond its hotspots.

Challenge

To understand what prevents visitors from exploring beyond the centre and remove that friction at the right moment in their journey.

Outcome & Impact

Changed behaviour: Visitors who received a prompt card changed their plans to visit locations they had not intended to explore.

Validated the model: 50+ visitors across four nationalities confirmed the intervention worked without an app, pre-commitment, or prior knowledge.

Generated investor interest: 5 investors expressed interest in taking the model forward at both city-wide and global scale.

Tourism ClusteringThe Challenge

London's top 10 attractions cluster inside Kensington & Chelsea, Camden, and Westminster—three of thirty-three boroughs—accounting for 71% of visitor spend and creating an uneven distribution of tourism revenue.

Tourism clustering research and visitor interview evidence

Secondary research confirmed highest-volume inbound markets (US, Canada, Western Europe) skew 25–34, are mobile-first, and arrive with loosely structured plans. These are not visitors who resist exploration. They are visitors who default to the familiar because the alternative requires effort they didn't budget for.

Complete Research Proposal

Interviews with visitors and industry experts—including TfL's Head of Information, Design & Partnerships and the Hilton Trafalgar's concierge manager—revealed a clear pattern.

People wanted off-the-beaten-path experiences but defaulted to central London due to high uncertainty and distrust of generic lists.

The intervention therefore had to be specific, physical, and feel like a local recommendation.

Visitors

“I like going to a mix of both but stumbling upon places organically always end up being my favorite memories.”

Erica (USA) - 35 years

“I avoid the touristy areas in London and prefer local bars, parks and friend-led exploration”

Saleem (France) - 27 years

“I have only planned a music gig and comedy show to go to in London and will explore in my free time.”

Hil (Norway) - 34 years

“I enjoy walking, local pubs, parks and exploring by tube & bus”

Varun (Canada) - 26 years

Experts

“People want something off-the-beaten path, a different offering to the usual (cheaper) tours.”

Terry (Edinburgh) - Tour Guide

“Visitors arrive with plans but still seek trusted recommendations for off-the-beaten path experiences.”

Gabriel (London) - Hilton Hotel, Trafalgar Sq.

“Visitors who explore beyond Zone 1 are more likely to return to London.”

Julie Dixon - TfL, Head of Information, Design & Partnerships

“Keeping parks and green spaces accessible is important for us, for visitors and Londoners alike”

Tim Webb - London Parks and Gardens, Interim Director

Desired OutcomeAim and Hypothesis

The pattern framed “decision making at specific moments in the journey” as a challenge and hence we came to three criteria that had to be true to be successful and what determined the final form of the intervention.

Disperse visitors

The first step needed to feel low-stakes and encourage exploration by connecting visitors to lesser-known places beyond iconic attractions.

Encourage detours

Generic “hidden gems” lists exist everywhere and are largely ignored. We had to be specific, curate and build trust.

Fit into the journey

Visitors are already in motion, so anything requiring a download, sign-up, or advance planning adds friction. The intervention had to meet them where they were.

Tourist journey timeline highlighting three intervention points

We identified three points in the tourist journey where these conditions could be created. Two visitor mindsets shaped how we designed for each: the Planned visitor, who needs permission to deviate, and the Spontaneous visitor, who needs a trusted starting point.

Experimenting in the wildTesting and Prototyping

Tangible objects are more intriguing and easy to attract attention, so we tested it out with simplified approaches.

Short-stay tourists are unlikely to download a new app.

Rather than building a digital-first product that would face adoption friction before it delivered any value, we designed a physical-first system with a lightweight digital layer.

Prompt cards as the main driver

  • A curated, pocket-sized guide to a specific off-centre neighbourhood, distributed at high-traffic tourist spots and placed at strategic low-traffic points across the city.
  • Cards were designed to be immediately useful without setup, scannable via QR code for those who wanted more depth and shareable—intended to be left behind or passed on.

Three distribution contexts were tested in parallel

Hand-distribution at tourist hotspots, card racks at visitor information points and QR stickers placed at street-level locations allowed us to test engagement and reach.

Launched social media first to build credibility.

Visitors are more likely to act on a recommendation they can verify is real. Building an @LDNdetour presence first meant the QR code on every card led somewhere trustworthy.

User JourneyFindings and Insights

Feedback from experts and users validated the interventions as well as revealed risks which urged us to keep developing the methods to fill in the gaps.

Service journey comparing planned and spontaneous visitors

The same card worked differently depending on visitor mindset. Two patterns emerged clearly from testing.

The Planner

  • Need permission to make room to discover something new.
  • An unexpected gap in the schedule becomes an opportunity for low-stakes exploration.
  • QR touchpoint encourages to take a detour without disrupting existing plans, turning spontaneity into a memorable part of the journey.
  • Return home and realise the best moments weren't always planned—get inspired to leave more intentional space for discovery on the next trip.

The Spontaneous

  • Driven by discovery, not a fixed itinerary.
  • A recommendation card picked up at King's Cross becomes a gateway to authentic outer-borough experiences, that guides beyond the typical tourist path.
  • The experience sparks social sharing and further exploration, while the card itself becomes a shared artefact which is left for the next guest or passed to a friend.
  • A simple physical touchpoint can turn spontaneous discovery into shared inspiration, extending the journey beyond one visitor and shaping future trips.

Outcome and ImpactSuccess Metrics

Testing produced clear directional evidence. It validated the hypothesis that visitors would go if prompted.

Notebook containing notes from London Detour field testing

Visitors took the deroute

“I wouldn't have gone to this area without the prompt. I'd planned on going to Big Ben on the way to Ruskin Park but skipped it and spent the day in Camberwell instead”

~Yuki (from Japan)

“I was initially a little nervous going to Brixton, but I was surprised how much fun I had and how cool the area was”

~Juliette (Canada)
  • Suggested the intervention worked without requiring any pre-commitment or app download.
  • These responses defined the key scale metrics: Replanning behaviour (did the visitor change a plan?), Pass-on rate (did the card reach a second visitor?) and Return intent (did the experience change how they'd plan their next trip?).

Accessibility concerns

“Walking was fine with me, but if I'd been with my mother it would have been hard to complete the prompt”

~Finlay (Denmark)

“I really liked the card idea, I think a digital version or way of saving it to my phone would be good too”

~Harrison (USA)
  • Testing revealed mobility and navigation barriers, highlighting the need for clearer route information and a digital option to save detours. The intervention assumed a level of physical mobility and confidence that not all visitors have.
  • The next version would need to include nearest tube or bus stop, estimated walking time, and an option to save the detour digitally rather than rely on memory or paper.

Phased Distribution PlanStrategy and Roadmap

The physical pilot was scoped for five key TfL stations (King's Cross, Kensington & Chelsea and Westminster) identified by visitor footfall data, giving enough geographic spread to test the intervention across both arrival contexts (Eurostar travellers, Heathrow transfers) and mid-trip moments.

Over the medium term we would keep reiterating the prompt locations by taking suggestions for new additions and also permanently integrate the QR codes into the Legible London street maps instead of stickers.

The long-term version is a data layer that uses time crowd signals to route visitors dynamically, taking pressure off saturated areas and distributing it to places that can absorb it.

In 1 year

  • Trial across up to 5 key TfL stations, eg. King's Cross and Westminster.

In 3–5 years

  • Reiterate with new locations & prompts.
  • Pre-arrival outreach—advertise on travel blogs, eg. Skyscanner.
  • QR code across Legible London maps.

In 10 years

  • Integrate with Google Maps crowd data to suggest areas which are less crowded via the digital platform.
