Martyn’s Law and How LiDAR, AI, and Directional Displays Can Save Lives in Crowded Spaces

Crowd Safety Technology

In sporting venues and concerts to busy transit hubs and urban centres, managing crowds has never been more complex. Unfortunately, history has also shown that poor crowd flow and delayed emergency communication can have devastating consequences. Martyn’s Law is the UK’s response to that reality. It received Royal Assent on 3 April 2025 and is intended to improve protective security and organisational preparedness across public premises and events.

Technology must rise to meet this challenge. Traditional evacuation signage and spoken instructions are not always effective. When panic or confusion spread within a crowd, real time guidance that is context aware and localised becomes critical. Today, the combination of LiDAR scanning, artificial intelligence and directional displays offers a new safety paradigm.

People follow signs, but only if the signs stay relevant

Research consistently shows that signage influences behaviour during emergencies, and that dynamic guidance can materially improve outcomes:

A practical architecture: LiDAR + AI + Directional displays

A modern crowd safety system support staff and security teams with real-time insight and real-time public instruction through three key layers:

1) LiDAR provides live spatial truth

LiDAR sensors create a continuously updated view of movement and density across zones without compromising individual privacy. It allows security teams to see where densities are rising and where paths are clearing in real-time.

2) AI turns data into decisions

AI decisioning fuses inputs like density flow, ticket data, and staff reports to compute the safest egress routes by zone and determine when to switch from orderly routing to rapid dispersal.

3) Directional displays deliver instructions people see and trust

Displays act as a high-visibility guidance layer, providing clear directional arrows, zone-specific messages, and multilingual prompts that are easily visible even in chaotic environments.

Why this combination supports Martyn’s Law outcomes

Martyn’s Law is aimed at better preparedness and reducing harm. A LiDAR + AI + display systems maps directly to the operational reality of that requirement by providing:

What this looks like in the real world

Here are three concrete examples that translate well to venues in scope of Martyn’s Law:

Scenario A: Suspicious package near a main concourse

LiDAR detects rising density; security flags the zone as restricted; AI reroutes traffic; and directional displays push “Alternative route to Exit B” to prevent a stop-and-stare crowd.

Scenario B: Fast-moving incident and partial exit closure

If a primary exit becomes unusable, AI recalculates the optimal distribution across remaining exits, and Miirage displays switch to zone-based instructions to limit congestion-causing cross-flows.

Scenario C: Outdoor event with controlled entry

Dynamic signage and routing prevent dangerous surges at gates and direct attendees to safer dispersal routes at the conclusion of the event.

Industry Interest and Early Discussions

Miirage is in active discussions with global event venues and transit authorities who recognise that the next generation of public safety must integrate sensors, predictive intelligence, and intuitive visual guidance. Pilot studies suggest that adaptive visual guidance can improve evacuation efficiency by up to 40%.

Why Holographic Signage Outperforms Traditional 2D Screens in Critical Moments

In high-pressure environments, attention is the most valuable currency. Holographic signage cuts through visual noise in a way flat 2D screens simply cannot. A life-sized digital presence creates depth, movement, and spatial realism that the human brain instinctively prioritises, making holographic guidance far more likely to be noticed, processed, and followed.

A calm, digitally created avatar delivers instructions in a way that feels human-to-human rather than system-to-crowd. People are neurologically wired to respond to faces, eye contact, and natural gestures. Studies in human–computer interaction show that embodied digital agents increase trust, comprehension, and compliance compared to text-only or icon-based signage. In stressful situations, this translates to faster decision-making and reduced panic.

Holographic signage also improves clarity. Directional cues can be paired with natural body language, such as pointing, turning, or walking motions, which removes ambiguity at critical junctions. Unlike static 2D screens that rely on reading under pressure, holographic avatars communicate intuitively, even across language barriers.

Efficiency is another key advantage. A single holographic system can dynamically adapt messaging in real time, responding to live data inputs without adding visual clutter. It replaces multiple static signs, reduces reliance on staff for verbal direction, and maintains consistent messaging across large or complex spaces.

Most importantly, holographic guidance feels reassuring. In moments of uncertainty, people look for leadership. A composed digital presence projecting confidence and authority helps stabilise crowd behaviour, supports orderly movement, and reinforces trust in the instructions being given.

When safety, speed, and clarity matter most, holographic signage is not just more engaging than a 2D

The Future of Safe Public Spaces

Combining LiDAR scans, AI models, and holographic guidance is a data-supported approach to reducing risk. As we move forward, the technology that captivates audiences can also preserve safety and save lives. When every second counts, the safest venues are those that can direct people to safety without panic.
