Sinusoidal Ramp – A Smarter Alternative to Speed Bumps & Speed Tables
The Sinusoidal Ramp is Rediweld’s latest innovation in traffic calming, designed to slow vehicles effectively while offering a smoother crossing for cyclists, cargo bikes, emergency vehicles, and everyday road users. Unlike a traditional speed bump or speed table, its unique sinusoidal profile combines safety with comfort, making it ideal for modern Active Travel schemes.
Engineered to Reduce Speed Without Compromising Comfort
Rediweld’s Sinusoidal Ramp is the latest addition to our Traffic Calming range, engineered to reduce vehicle speeds effectively while offering a noticeably smoother crossing than traditional speed cushions.
As more Active Travel schemes are introduced, this new option provides an effective way to manage speeds in key locations without compromising performance or compliance.
Available with Kerb to Kerb or Tapered Sides, the Sinusoidal Ramp removes the need for additional drainage considerations and can be easily positioned to allow the natural flow of water.
Key Benefits of the Sinusoidal Ramp
Proven Performance
Real-world installations in York and Worcester have reduced vehicle speeds to below 10 mph, proving an effective alternative to traditional speed bumps and raised tables.
Cyclist & User-Friendly
A shallow initial rise creates a smoother experience for cyclists, cargo bikes, and adapted mobility vehicles, improving accessibility while still discouraging speeding.
Fast, Simple Installation
Surface-mounted and pre-formed, the ramp requires no excavation, reducing road closures and disruption. The modular system ensures a consistent sinusoidal profile every time.
Flexible Design Options
Currently available as a kerb-to-kerb solution, with tapered side options in development to suit a wide range of road layouts and traffic-calming requirements.
Sustainable & UK-Made
Manufactured in the UK from recycled rubber, supporting reduced carbon impact while delivering durable, long-term performance.

FAQs - Sinusoidal Ramp
How does a Sinusoidal Ramp differ from a standard speed bump?
Unlike traditional speed bumps that create a sudden jolt, the Sinusoidal Ramp features a smooth, engineered sinusoidal profile. This design effectively reduces vehicle speeds while providing a more comfortable transition for cyclists, mobility users, and larger vehicles.
Is the Sinusoidal Ramp as effective as a speed table?
Yes. Independent trials and live installations have recorded vehicle speeds reduced to below 10 mph. This performance matches or exceeds many traditional speed tables, while offering improved accessibility for active travel and shared-use streets.
Are Sinusoidal Ramps suitable for emergency vehicles?
Yes. The gradual rise and controlled profile allow ambulances, fire appliances, and buses to pass more smoothly than over conventional speed bumps or cushions, without compromising traffic-calming effectiveness.
How quickly can a Sinusoidal Ramp be installed?
The ramp is surface-mounted and pre-formed, requiring no excavation or spoil removal. Its modular design enables fast installation with minimal road closures and reduced disruption compared to asphalt or concrete alternatives.
Is the Sinusoidal Ramp an environmentally responsible solution?
Yes. Manufactured in the UK using recycled car tyres, the Sinusoidal Ramp helps reduce waste and carbon impact while delivering long-lasting, high-performance traffic calming.
