2nd Generation Ramp Metering

Dynniq partners with National Highways to develop a new generation of Ramp Metering

Why the need for an updated Ramp Metering system?

To address congestion on major arterial roads, where too many vehicles joining from a slip road causes an unnecessary queueing of traffic, National Highways designed a Ramp Metering solution to control the number of vehicles joining from the slip road.

Our role was to design the new system as a proof of concept, test, deploy and maintain the system.

What is it? 

Ramp Metering is a traffic management system that helps regulate the merging of slip road traffic onto the main flow more efficiently. This is normally done through traffic signals on the slip roads which breaks the traffic down and enables the safe merging of traffic and prevents over capacity of vehicles on the road network resulting in congestion.

How does it work?

This technology was first deployed in 2006 and was based on induction loop technology but eventually the cost to both install and maintain became prohibitive in terms of return on investment, so a new ramp metering system was needed.

The new system uses adaptive algorithms and an improved, open interface. Fewer changes to infrastructure are required as wireless magnetometers do not require extensive cabling, power supplies or communication to install.

With cloud technology and third-party interfaces, the system can be controlled centrally and remotely, allowing Operators to still benefit from Ramp Metering whilst future-proofing it to keep up with emerging technologies.

Where is it being deployed?

Currently, this system is has been deployed on M25 Junction 13 northbound slip road and the A3 Dennis Roundabout southbound slip road.
