An intelligent over-size vehicle detection system designed to stop bridge and street strikes before impact, protecting infrastructure, avoiding disruption, and improving safety.
Built for rail bridges and constrained urban environments.
The Challenge
Bridge Strikes Are a Persistent Network Risk
Bridge strikes remain one of the most common causes of infrastructure damage and rail disruption.
Each year they result in:
- Infrastructure damage
- Service delays and cancellations
- Expensive inspections and repairs
- Safety risks to drivers, passengers, and rail staff
Traditional warning signage often fails to prevent incidents because drivers only recognise the problem when it is already too late.
BridgeBouncer was designed to intervene before the vehicle reaches the bridge.
The Approach
Intelligent Over-Height Vehicle Detection
BridgeBouncer uses detection technology to identify vehicles that exceed height restrictions as they approach vulnerable structures.
Once detected, the system activates clear visual and audible warnings designed to capture driver attention and redirect the vehicle before a collision occurs.
This early intervention significantly reduces the risk of impact.
Digital Accessibility
BridgeBouncer combines multiple technologies to create an early warning system.
Vehicle Detection
Sensors monitor approaching vehicles and identify those that exceed safe clearance heights.
Targeted Warning Systems
When an over-height vehicle is detected, highly visible warning systems activate immediately, alerting the driver and signalling the need to stop or reroute.
Driver Decision Window
Because warnings are delivered well before the bridge itself, drivers have time to safely stop or change route.
This dramatically increases the likelihood that collisions are avoided.
Why It Matters
Bridge strikes cause significant operational disruption across rail networks.
Preventing a single strike can avoid:
- Network delays
- Passenger disruption
- Infrastructure damage
- Emergency response costs
BridgeBouncer helps protect both rail infrastructure and road users, delivering safety and operational benefits.
Beyond Rail Bridges
While originally developed for rail infrastructure, BridgeBouncer is increasingly relevant for other environments, including:
- Low urban bridges
- Tunnels and underpasses
- Freight routes
- Construction zones
- Restricted urban streets
This makes the system applicable across multiple transport sectors worldwide.
Deployment
BridgeBouncer is designed to integrate into existing infrastructure and can be deployed as part of wider safety and asset protection strategies.
RASIC works with transport operators and infrastructure owners to identify suitable locations and deploy the system effectively.
