Dynniq has confirmed completion of a project to aid in the efficient and safe movement of traffic using what it calls the very latest in traffic signals, management systems and enforcement camera technology.

It says the Designed to release the burden of motorised traffic from the Forth Road Bridge, the new 1.7 miles (2.7km) publicly-funded Queensferry Crossing is the biggest infrastructure project in Scotland in a generation and will replace the Forth Road Bridge as the main road route between Edinburgh and Fife, carrying 24 million vehicles a year.

 Working for Forth crossing bridge Constructors (FCBC) between June 2015 and August 2017, Dynniq says it carried out the installation and commission of 15 ELV Traffic Signal sites for the FRC Principal Contract project. The sites are situated both North, (Fife Council) and South (City of Edinburgh council) of the New £1.35 Billion Forth Replacement Crossing project consisting of the Queensferry crossing and major trunk roads and high profile locations.

During the course of the signalling works, Dynniq through installation of carriageway loops facilitated count sites at each of the signalling sites. These count sites provides data which tracks peaks and dips in traffic volume by the number of vehicles approaching the signalling sites and gives capability to adjust the signalling sequencing to better suit the traffic conditions. The traffic count data produced also includes average daily traffic volume, current and previous count for type of vehicle, direction of travel and distance between vehicles.

Traffic lights running under SCOOT control, will be able to adapt to the traffic flow and maintain it at optimal levels via Dynniq’s Urban Traffic Control System (UTC) and their Intelligent PTC-1 Traffic signal Controller. 

Dynniq says the installed UTC system will deliver a time tabled operating 24X7 live performance adapting control system, empowering the operator to manage the network via its user friendly interfaces.

Following a procurement exercise the speed enforcement system chosen by Transport Scotland to was the Dynniq HADECS3 system. This was developed with Highways England to support the implementation of mandatory variable speed limits on selected motorways. It combines radar technology for speed detection, cameras for image capture, and data encryption techniques to ensure safe and secure transmission of evidence files.

 The Dynniq HADECS3 solution provides a digital enforcement camera system capable of enforcing variable mandatory speed limits in single and adjacent multiple lanes. The system comprises in-station and out-station equipment and has been developed and tested in accordance with the requirements of the UK Home Office Type Approval.

 As the longest three-tower, cable-stayed bridge in the world, the Queensferry Crossing will take the vast bulk of the current traffic load and, unlike the Forth Road Bridge, is expected to remain open in all but the most extreme weathers. The Forth Road Bridge will become a Public Transport Corridor to be used by buses, taxis, some motorcycles, cycles and pedestrians. Providing a safe and efficient link between the City of Edinburgh and Fife for over 24 million vehicles a year called for technologies which could effectively manage traffic flow, deliver traffic count data and provide enforcement in the locality.
