TileStop — Smart Pavement Guidance

TileStop transforms the bus stop experience through a series of illuminated tiles that visually communicate bus arrival. The system enhances clarity, inclusivity, and safety for commuters by translating complex transport data into intuitive light-based signals that guide users across all languages and abilities

THE PROBLEM

As Brisbane prepares for the 2032 Olympic Games, many tourists will travel beyond the CBD to explore suburban areas. However, suburban bus stops often lack real-time information, clear signage, and accessible design features. Unlike central transport hubs, these stops rely heavily on small printed timetables and mobile apps—creating confusion for visitors unfamiliar with the local transport system.

Without visual communication or multilingual guidance, tourists are left uncertain about bus arrivals or routes, leading to frustration, missed services, and a poor public transport experience. This highlights a growing need for inclusive, intuitive, and easily understood communication systems at suburban bus stops.

Statistics

Research conducted at suburban Brisbane bus stops revealed widespread dependence on mobile apps for real-time updates, with 100% of surveyed users relying on digital navigation tools such as TransLink, Google Maps, or Apple Maps. However, 73% reported inconsistent arrival accuracy, and 60% expressed frustration with unreliable timing or app dependence when battery or signal failed.

Many suburban stops also lack clear visual signage, lighting, and multilingual communication, leaving elderly commuters, tourists, and visually impaired users uncertain about bus arrivals. This inconsistency between physical and digital information contributes to confusion, stress, and reduced trust in the suburban public transport system.

These findings highlight a pressing need for an inclusive, low-maintenance, and universally readable solution that provides real-time visual communication directly at the stop—bridging the gap between digital reliance and physical accessibility.

Benchmarking

The benchmarking process explored global examples of smart transport infrastructure and real-time communication systems, focusing on how different cities approach user information and accessibility. Case studies such as Singapore’s Smart Bus Stop, London’s TfL Countdown System, and Tokyo’s Intelligent Transport Network demonstrated strong advancements in digital communication and data integration. These systems successfully deliver live updates, route planning, and service notifications through digital screens or mobile applications, significantly improving efficiency for local commuters.

However, analysis revealed that most of these solutions are designed with local users in mind, relying heavily on English or region-specific language interfaces, smartphone ownership, and network connectivity. This creates an accessibility gap for foreign users, tourists, and elderly commuters, who may struggle to interpret digital interfaces or lack access to mobile data.

Additionally, suburban regions—particularly outside major transport hubs—show minimal investment in smart infrastructure, resulting in a noticeable disparity between central city transport technology and outer-area accessibility. This benchmarking highlights a clear opportunity for more inclusive, low-barrier communication methods that support both local and international users across all areas of public transport.

Benchmarking Matrix

Initial Concepts

Early concept exploration focused on improving visibility, accessibility, and communication between passengers and buses. Transit Floor introduced dynamic pavement screens for real-time route displays. Pole in Progress used illuminated rings to signal approaching buses, while Halo Stop proposed a glowing shelter canopy for enhanced visibility and identity. These studies informed the final direction — Journey Tiles — a series of ground-embedded tiles that light sequentially as the bus approaches. The system offers clear, language-free feedback for commuters and tourists alike, bridging communication gaps and making suburban bus travel more intuitive and inclusive.

Initial Concepts

Prototyping

The prototyping stage

The prototyping stage focused on developing a realistic, functional representation of the TileStop system to evaluate its form, lighting sequence, and user interaction. A full-scale model was produced to simulate how the tiles communicate the bus’s arrival progression and how users perceive light transitions in real-world suburban conditions.

Various fabrication techniques were used throughout the process to replicate the final material and finish quality. The tile shell was 3D printed using PLA and then sanded, primed, and painted to achieve a realistic stainless-steel finish. TPU filament was utilised to create the tactile surface layer, replicating the flexible and slip-resistant texture of compliant TGSI domes. Internal lighting was achieved using LED strips connected to a low-voltage power supply, programmed to display a sequential pattern from red to green to represent bus proximity.

Additional processes such as laser cutting, manual assembly, sanding, and detailing were used to ensure clean edges, consistent surface quality, and accurate component alignment. The resulting prototype effectively demonstrates the design’s accessibility, manufacturability, and visual communication, providing a clear, functional preview of how the TileStop system would perform in a real bus stop environment.

materials

Stainless steel 316

The tile housing and structural frame are made from 2–3 mm extruded 316 marine-grade stainless steel, chosen for its strength, corrosion resistance, and weatherproof properties. This material ensures longevity in outdoor environments exposed to rain, heat, and foot traffic. The satin finish provides a refined, low-maintenance appearance that resists scratches and staining.

polycarbonate lens & tactile

The top surface lens is moulded from impact-resistant polycarbonate with high optical clarity and UV stability. It diffuses light evenly across the tile and maintains strength under pedestrian loads. The polycarbonate layer also integrates TGSI-compliant tactile indicators, removing the need for separate overlays and reducing maintenance while maintaining visual and haptic contrast.

Silicone Gaskets and Sealants

A silicone gasket is fitted between the housing and lens to achieve an IP67 waterproof seal, protecting the internal lighting from moisture, dust, and temperature variations. A silicone-based sealant is applied at screw points and seams to maintain environmental protection and long-term durability.

Service Box

The service box acts as the central control and power distribution unit for the TileStop system, designed for easy maintenance, protection, and modularity. It is located beneath or beside the tile array and allows technicians to access the electrical and lighting systems without dismantling individual tiles.

Constructed from 316 stainless steel, the service box provides corrosion resistance, impact strength, and weatherproof performance consistent with the tile housings. The interior components are mounted on an insulated tray for safe servicing, with sealed cable inlets to prevent dust or moisture ingress. The box is rated to IP67, ensuring complete protection against rain, debris, and accidental splashing.

Inside the unit, a low-voltage DC power supply drives the LED system, while quick-release connectors and modular wiring harnesses enable straightforward replacement or upgrades. Ventilation holes with fine mesh and silicone seals regulate temperature while maintaining waterproof integrity.

Connectors

The TileStop system is designed around a plug-and-play connection framework that enables simple installation, replacement, and maintenance of individual components. Each tile connects directly to the central service box, which functions as the hub for power distribution and signal control.

The system uses waterproof quick-connect terminals (rated IP67) and low-voltage DC wiring, allowing each tile to be detached and serviced independently without disrupting the network. This modular setup eliminates the need for hardwired connections, significantly reducing installation time and simplifying maintenance in outdoor environments.

Each tile contains a pre-terminated connector that links to a main harness running from the service box. During installation, tiles can be easily “clicked” into place, automatically linking power and data through sealed male-female connectors. This approach supports rapid replacement, as technicians can remove and reconnect individual tiles using standard tools without electrical expertise.

The service box internally manages power regulation and signal sequencing, ensuring consistent lighting transitions across all connected tiles. This modular plug-and-play system enhances safety, scalability, and serviceability, aligning with best practices in Design for Assembly (DFA) and public infrastructure maintenance standards.

Tactiles

The tactile surface of each TileStop unit is designed to comply with AS/NZS 1428.4.1:2009, providing safe, accessible navigation for vision-impaired users. The tactile indicators use a straight-line (directional/corduroy) pattern, which assists users in maintaining alignment and orientation toward the bus boarding area.

Each tactile ridge is moulded directly into the polycarbonate top lens, creating a strong, seamless interface between the walking surface and the integrated lighting system. This single-material construction enhances durability, weather resistance, and maintenance efficiency, eliminating issues associated with adhesive or applied overlays.

The polycarbonate surface is UV-stabilised, slip-resistant, and impact-resistant, designed to withstand outdoor exposure and heavy pedestrian traffic. The raised linear pattern—measuring approximately 5 ± 0.5 mm in height—provides distinct tactile feedback underfoot and is easily detectable by mobility aids such as canes or wheelchairs.

By integrating tactile cues into the illuminated tile, the system ensures universal accessibility and intuitive guidance, supporting both local commuters and international visitors in safely navigating suburban bus environments.

Installation

The TileStop system is designed as a modular installation that adapts to a range of suburban and urban bus stop configurations. The arrangement of tiles can vary depending on site constraints, with a maximum of five tiles used per stop. Each tile represents one stage of the bus’s approach, lighting sequentially to provide a clear visual countdown to arrival.

Before installation, a cavity is created within the existing concrete pavement to house the tile array. The depth and footprint of the cavity are determined by the number of tiles required at each location.

The full tile assembly—including housing, tactile surface, and service connections—is then lowered into the cavity and secured using stainless-steel countersunk fasteners. Silicone seals and gaskets are applied along the perimeter to maintain an IP67-rated waterproof barrier, while the modular design allows each tile or service box to be removed individually for maintenance.
