Want to know how we can help with your Bus NAP?
The Predictable Stop Kit is an ongoing, funded project to develop a modular retrofit accessibility system for public transport stops. This pack shows what we have built and learned so far, sets out what we can offer local authorities and public transport operators during this phase of our project, and opens up the ways we could work together ahead of a live trials and bus network accessibility plan deadlines in 2027.
From sketch to street: our first idea, drawn on an e-ink tablet.

We know local authority and transport planning teams are stretched, so here’s the short version: what we’d ask from you and when things are happening. Full detail on everything below follows later in this pack.
A named contact within your organisation and your transport planning team, so we can keep you updated as the project progresses.
Early conversations about stop locations and passenger needs, so our plans for a live trial reflect real world conditions for passengers.
If you are preparing your Bus Network Accessibility Plan, a conversation about how the Predictable Stop Kit could help you describe, evidence and report on what your stops provide. Learn more about how PSK can help with your Bus NAP.
Now – October 2026: we build and test the pre-demonstrator with our co-design cohort at the Sussex Innovation Centre, Brighton.
December 2026: partners are welcome to visit the simulated stop and try the pre-demonstrator for themselves, during our second round of testing.
December 2026 – January 2027: we evaluate everything we’ve learned and build the case and plan for a live trial.
March 2027: planned start of a real-world trial, with committed local authority partners.
PSK development is funded through the ncat Scaling Innovation Programme 2. There’s no fee, procurement process, or funding commitment on your side to take part in Phase 3. That funding covers our costs and our co-designers’ costs. It doesn’t cover your own staff time or travel if your team visits us in Brighton, so please budget for that as you would for any other site visit. We’re not asking for a commitment to a live trial, only the chance to work with you as we build towards one.

The Predictable Stop Kit is a modular retrofit device for public transport stops. It gives real-time travel information through several channels at once: a 13.3 inch e-paper display, audio announcements, Bluetooth audio broadcast (Auracast) to hearing aids and earphones, a tactile push button with visual feedback, an induction loop, and a Braille stop code.
The display has a toughened front coating and is optimised for pole mounting or fixing to any other fixed surface. The unit runs on wireless connectivity with battery and solar capability, with optional illumination, and can be attached to a round post, square post, or wall.
It needs no smartphone, no app, and no fob. A passenger can get the same information whether they read it, hear it, feel it, or use their own hearing aid.
The Predictable Stop Kit is built around the social model of disability. Barriers at a public transport stop are treated as environmental and systemic, not as something wrong with the person waiting. That means the kit is designed to remove barriers from the stop itself, rather than asking disabled passengers to carry an extra device or download an app to work around them.
Most accessibility work in public transport focuses on vehicles or on journey-planning apps. Far fewer projects look at the stop itself, even though this is where many of the barriers start: unclear signage, unreliable audio, no consistent place to wait or board, and information that only works if you can see a screen or use a smartphone.
The Predictable Stop Kit is built to close that gap. It gives blind and partially sighted passengers reliable audio information. It gives d/Deaf and hard of hearing passengers clear visual information and induction loop or Auracast audio direct to their hearing aid. It gives neurodiverse and mobility-impaired passengers a stop that behaves the same way every time.
On the Scaling Innovation Programme, the Predictable Stop Kit is the only infrastructure solution that has been advanced to Phase 2 at pre-demonstrator level, with continued support from ncat and the Motability Foundation.

Built and tested Cosmo, our working proof-of-concept prototype, completed April 2026.
Ran co-design sessions with disabled people, which directly shaped the design.
Developed a logic model with clear, benchmarked success metrics grounded in digital twin modelling.
Secured letters of support from Campaign for Better Transport and E Ink.
Won a Special Commendation from Sussex Innovation’s AccelerateTech programme, securing six months of free office space.
Secured Phase 2 funding of £100,000.
A passenger presses the tactile button, mounted in a fixed, standard position, and gets a visual confirmation and a spoken announcement: stop name, next services, route numbers, and minutes to arrival.
The e-paper display shows the same information visually, in a high-contrast, consistent layout, for partially sighted passengers and anyone who prefers to read it.
Audio can also be delivered privately over Auracast, straight to a passenger’s own hearing aid or earphones, alongside the induction loop for existing hearing aid users.
A Braille stop code gives blind passengers a way to confirm they are at the right stop.
All information is pulled from live open transport data, so it reflects what is actually happening, not a fixed timetable.

Phase 2 of our project runs from August 2026 to January 2027, funded through the ncat Scaling Innovation Programme 2. This is the stage where we build and test a pre-demonstrator version of the Predictable Stop Kit, working directly with disabled people throughout. The phase is structured around three build-and-test cycles:
Build 1 (August–September 2026): first iteration of the pre-demonstrator, running alongside our first co-design workshop.
Build 2 (September–October 2026): a second iteration, informed by that workshop, installed as a simulated stop at the Sussex Innovation Centre. This is our test environment. It is not a live bus stop, but it is close enough to generate meaningful data.
Testing round 1 (October 2026): co-designers return as co-testers to interact with the pre-demonstrator in the simulated stop and give feedback against our success metrics.
Build 3 and testing round 2 (November–December 2026): a further iteration and a second round of testing and feedback.
Evaluation (mid-December 2026 to January 2027): we bring together everything we’ve learned, write it up, and build the case and the plan for a live trial.
Throughout, we’re testing the Predictable Stop Kit against six success metrics developed with disabled co-designers: task completion, confidence, comprehension time, accessibility equity across different access needs, zero new barriers introduced, and information accuracy against live transport data. Together, these give us the evidence base for a live trial.
We are honest that this project is at pre-demonstrator stage. Current testing takes place in a simulated stop environment at the Sussex Innovation Centre, not at a live bus stop. A real-world trial will take place in March 2027, with support from local authorities who are committed to trialing accessible public transport solutions.
A trial needs a realistic range of stop types in one place: rural, suburban, and central city.
Areas with high bus use per person and a high proportion of disabled residents give us the clearest evidence of what the Predictable Stop Kit changes for passengers.
Synergy: we are looking for areas with other accessible transport initiatives and innovations already under way.
Where related devices are already in place, such as buttons that read out upcoming bus times, Predictable Stop Kit can be tested alongside them rather than in isolation.
We would like local authority and public transport partners to be closely involved before any live trial begins, so that live trials are built around what actually matters to your passengers and your organisation, not just what we assumed in the lab.
An invitation to visit the simulated stop at Sussex Innovation Centre in December, during our second round of testing, to see the Predictable Stop Kit working and try it for yourselves alongside our co-designers.
Early and direct access to the evidence we’re building through Phase 2: task completion, confidence scores, comprehension times, and information accuracy, alongside what co-designers tell us. This evidence is for your own accessibility case only, whether that’s for BSIP reporting, funding bids, or internal business cases.
The chance to help shape our second and third build iterations. If there are specific stops, routes, or passenger concerns you want us to test against, we can factor that into the pre-demonstrator before Phase 3 begins.
If a Phase 3 trial goes ahead, we would want it in an area like yours. Getting your input now on stop types, locations, and what a future accessibility requirement in a bus service tender might look like means any future trial, and any future procurement conversation, starts from a shared understanding rather than a cold approach.
This project is fully funded through the ncat Scaling Innovation Programme 2, so there’s no fee and no funding commitment on your side for any of the above. That covers our costs and our co-designers’ costs, not your own staff time or travel if you visit us in Brighton. Please budget for that as you would for any other site visit. We’re not asking for a commitment to a live trial, only the chance to work with you as we build towards one.
Every local transport authority in England must publish a Bus Network Accessibility Plan by 1 April 2027. The plan is your own assessment of how far the network lets disabled people travel independently, safely and in reasonable comfort.
The Department for Transport guidance rates live bus information on how many senses and groups it serves. Information shown only visually is rated inadequate. Visual, audible and online information that meets minimum standards is adequate. Information tailored to different impairment groups, or co-designed, is good.
The Predictable Stop Kit is built to score well on that scale. It gives live information visually, audibly, through an induction loop and over Auracast from one unit, shaped by co-design with disabled people. The guidance names audible departures wherever live departures are shown visually, and Auracast, as example commitments an authority could make.
In our next build we are working towards a per-stop feature record, so you can describe what each stop provides in the wording the Bus NAP template asks for, including a status such as available now or available from a date.
We are reporting our test results by the impairment groups the guidance uses, with the same grouping each round, so they can feed your assessment and its later reviews.
Telemetry on announcements, button presses, display refreshes and faults, tagged with each stop code, is planned to help you monitor and report on commitments over time.
The short version of how to get involved, and our key dates, are at the top of this pack. If you’d like to talk it through, or you’re ready to nominate a contact within your organisation, get in touch.
