ADCI and HERE Help GreenRoad Build a Bridge-Strike Prevention System

The Partnership: Data Strategy Meets GIS Expertise

At ADCi, we operate on a specific principle:  our clients are the experts in their domains, and we are the experts in the GIS data that powers it. Our high-touch approach focuses on identifying the specific data layers, routing attributes, and geocoding precision required to turn a concept into a functional solution.

When GreenRoad, a global leader in digital fleet safety telematics, sought to eliminate bridge strikes—one of the most persistent and costly hazards in commercial transportation—they needed more than standard mapping. They required a data strategy capable of protecting infrastructure and lives across the UK.

The Challenge: Solving the Low-Clearance Gap

Bridge strikes are largely preventable, yet they continue to cause millions in rail delays and infrastructure damage annually. For GreenRoad, building an effective prevention tool required solving two technical hurdles:

• Attribute Precision: High-capacity vehicles, such as double-decker buses, require height-specific data to avoid "alarm fatigue," where drivers ignore non-relevant warnings.
  
  
• Operational Reliability: The system needed to reference a massive database of over 18,000 low bridges across the UK and function in real-time, regardless of connectivity.

The ADCi Consultative Approach

GreenRoad’s GIS team had a clear vision for their Low Bridge Alerting System; they partnered with ADCi to acquire the exact data components needed to build it. 

ADCi was able to get GreenRoad the specific suite of HERE Technologies products they needed to be successful:

• HERE Map Data: Provided the foundational building block for the entire system (learn more).
• HERE Road Infrastructure & Usage: Delivered the critical data on low-clearance bridges and physical constraints (learn more).
• HERE Road Rules & Regulations: Ensured vehicle compliance with posted legal restrictions and speed limits. (learn more)

Implementation and Fleet-Wide Success

With the data strategy finalized, GreenRoad integrated these attributes into their driver alert systems. ADCi was on hand for ongoing support so GreenRoad could ensure the data layers performed seamlessly within their proprietary environment.

The real-world impact was immediate:

• National Deployment: Stagecoach, the UK's largest bus operator, invested £4 million to install the technology across 4,000 double-decker buses and coaches.
   
• Measurable Safety Gains: Operators using the system saw a 50–70% reduction in bridge and tunnel collisions.
   
• Reduced Liability: The implementation contributed to lower operational costs and a reduction in insurance claims by up to 33%.

Results: Data-Driven Infrastructure Protection

By partnering with ADCi to source the right GIS data, GreenRoad moved beyond simple tracking to proactive prevention. Their system now provides drivers with audible, real-time alerts that allow for safe rerouting before an incident occurs.

"Once we launched the product with our customers, the change was immediate. The rate of low bridge accidents went down in a significant way."
