By deploying instant, high-frequency messaging before the arrival of the emergency services, CRAWL targets the time between incident to response to prevent secondary collisions, which account for up to 15% of all highway crashes. It provides an immediate, directional or bi-directional warning capability that saves lives.
A Revolutionary Step Change in Highway Safety
Detection to Incident Response in 14 Seconds
Designed with safety at its core
Lagan CRAWL detects hazards in real time, providing location specific incident responses, guiding road users and the correct personnel to the most effective response. By detecting, validating, and notifying within 14 seconds, this faster intervention and resource allocation means safer journeys for every road user, no matter the conditions.
Key Features
Prevention of Secondary Collisions
Protection in the critical time between incident and response.
Wrong Way Driver Detection
CRAWL automatically detects wrong way drivers on the carriageway
Will automatically display warnings to oncoming motorists dynamically maintaining up to 10km* in advance of the errant vehicle. This system greatly reduces the probability of head on collisions by providing live, real time, reliable warning information to road users giving them the awareness and opportunity to slow down and take appropriate actions until the danger passes.

Efficient Messaging
Rapid awareness through high-frequency, low-latency messaging.
Standard gantries are often too far apart. CRAWL uses short, continuous via frequency of location, and targeted messaging sequences designed to be quickly digested and understood. This ensures drivers engage faster and react more immediately than they would with traditional, isolated signage.
Hazard Location Specific
Right message, right place, right time.
Minimize "warning fatigue" by restricting displays to the immediate hazard zone. CRAWL ensures warnings are relevant to the local context and, crucially, guarantees all signs are deactivated the moment the hazard has passed to maintain driver trust.
Universal Accessibility
Safety for every driver, regardless of vehicle tech.
While V2X and smart-car tech are growing, they aren't universal. CRAWL ensures 100% of motorists receive life-saving warnings visually, providing a safety net for all road users while remaining future-proofed for V2X integration.
Digital Security
Giving clients full control over the data generated.
All data remains under operator control, including data residency, access governance, encryption and privacy, in non-proprietary formats, ensuring jurisdictional protection and resilience to geopolitical risk. GDPR-compliant and future-proof, it enables deep analysis and V2X integration, optimising road networks without paywalls.
