Innovative RLCS solution for Cheshire East

Published:01-03-2021

Ringway Jacobs positions road safety and minimal disruption from essential roadworks at the heart of its innovation strategy. Dynniq has been engaged as a technology partner to design and install an innovative Remote Lamp Control System (RLCS) solution over the last 3 years in Cheshire East to address these challenges.

Traditional traffic light signal installations often require costly new infrastructure and the installation of extensive ducting infrastructure. Any such groundworks has associated safety risks, in addition to causing major road disruptions, putting road user safety at risk and leading to an increase in negative road user complaints.

Dynniq’s innovative Remote Lamp Control System (RLCS) is based on a distributed Controller system. This takes some of the core controller technology, which is traditionally located centrally within the Traffic Signal Controller, and distributes this functionality locally to modules housed within the Signal Head.

This distributed approach allows signal poles to be “daisy-chained” together, which results in a significant reduction in the both the number and size of cables required to support an installation. The significantly smaller size also enables the cables to be installed in 20mm sub-ducts, meaning installing less and shallower ducting in the ground. This method allows for multiple installation options with much less disruption to the road network and a quicker turnaround both in turn resulting in higher road user satisfaction and a significant reduction in costs.

These projects initially commenced with Dynniq installing a trial site on one pedestrian crossing to showcase the benefits of the RLCS system, and Dynniq engineers were able to install and commission a full working standalone crossing in under a day.

A key challenge of this project was an additional complex junction positioned over a canal, where it was difficult to install a traditional ducting system, due to the restrictions associated with excavating within the bridge deck. Due to RLCS needing both fewer and shallower ducting, this provided the ideal solution and Dynniq we able adapt the RLCS solution to install the traffic signals on either side of the canal.

After conducting the two trial sites, Cheshire East now use the RLCS solution on most of their Pedestrian Crossings installations.

“For us, innovation is key and we want to be seen to be leading the way in the use of working methods and technology which provides benefit in relation to increased workforce safety and reducing public disruption. After the trial site, we saw the value of this new advanced solution and decided to fully implement the use of RLCS at the majority of new sites where the provision of traditional duct crossings would cause conflict with utility company apparatus or excess delay to the road user”
