SRL Traffic Systems has become one of the first manufacturers to achieve TOPAS 2540A compliance for its next generation of portable traffic signals. UltraLight is its first compliant signal and will be launched at Highways UK.  The product forms the basis of REMOS, another new launch and one of the first scalable remotely operated temporary signal solutions to enable off-site operation at multiple locations, including those in rural areas. 

UltraLight portable traffic signal

Since its launch in June 2023, TOPAS 2540A compliance is increasingly stipulated in intelligent transport system (ITS) contracts. UltraLight’s compliance allows customers to quickly identify it as a safe and effective solution, facilitating diligent procurement.

A competitive run time and the longevity of the batteries’ bullet lock protection precludes the need for frequent exchanges, saving energy, time and money and minimising the amount of time that road workers need to spend in live highways scenarios.

The new product is compatible with SRL’s Solar PLUS, enabling UltraLight customers choosing to incorporate the solar technology into their signals to harness renewable energy and limit their carbon footprint.

UltraLight is engineered to withstand the toughest weather conditions: it is IP57 rated and protects against water ingress. The signal incorporates SRL’s new radio acoustic wave stabiliser which minimises communication interference and a new optimum size antenna ground plate that promotes reliable transmission and accurate telematic monitoring. It also features as standard SRL’s enhanced adaptive detection system with automatic configuration.

All SRL’s portable traffic signals manufactured in future will be TOPAS 2540A compliant. The company already has a fleet of the latest 2516D TOPAS registered variable message signs (VMS) and is focused on gaining additional certifications for further product categories.

REMOS remotely operated signal solution

Designed to allow traffic management organisations to minimise the number of personnel stationed on site in live traffic lanes, REMOS promotes safety, minimising the risk of accidents and roadside abuse. 

Labour costs too are minimised as one operative may manage several sites, monitoring traffic flows and efficiently making frequent interventions to prevent and eliminate bottlenecks. REMOS’ single-person control also facilitates reliable operation, even in the face of the frequent staff shortages that characterise the traffic management sector.

The only product to incorporate bandwidth compression technology, REMOS not only reduces video image streaming costs but is also the most resilient solution on the market. It offers clear line of sight on all approaches. 

The environmental benefits of the solution are significant:  SRL estimates that the deployment of REMOS can save contractors in the region of 3,564 kg CO₂ per operative per annum no longer required on site.

REMOS incorporates temporary traffic signal boxes, a REMOS signal head with built-in CCTV cameras, along with a remote traffic management control box (RTMC) and SRL Control Hub subscription.  The new solution has undergone successful trials and will be piloted early next year.

Said SRL’s chief executive officer Mark Eburne: “SRL is laser-focused on the development of innovative, sustainable ITS solutions that promote safety and efficiency on our road networks.  We are very proud to launch two such pioneering products to the traffic management sector, and to be one of the first manufacturers to achieve the new TOPAS 2540A compliance.”

SRL is one of Europe’s largest manufacturers and suppliers of portable and temporary ITS equipment and integrated solutions to the traffic management, construction, utilities and events sectors. Its product portfolio comprises CCTV, work-zone protection barriers and ANPR in addition to traffic and pedestrian signals, VMS and integrated solutions.
