Detect. Adapt. Keep Traffic Moving.

Let the traffic flow

Our optional Radar Vehicle Detection feature increases work zone safety and efficiency by detecting oncoming vehicles and dynamically adjusting green light duration.

Particularly useful during heavy traffic on one side, it ensures smoother flow and reduces delays. Operators can customize green times and vehicle detection settings to suit any work zone.

By eliminating unnecessary stops, it minimizes driver frustration and keeps traffic moving efficiently.

Portable traffic lights with radar, internet connectivity, GPS, and GSM for smart traffic management

Clear Timing, Less Stress.

countdown Timer

Our portable traffic lights feature a built-in countdown timer on the yellow signal as standard, improving traffic flow and safety.

Unlike competitors who offer timers as costly add-ons, our solution delivers better value right from the start.

Designed to adapt, SPHERE portable traffic lights ensure safety and efficiency across all scenarios.

Designed to adapt, SPHERE portable traffic lights ensure safety and efficiency across all scenarios.

RADAR MODEThe green phase duration adjusts based on vehicle presence.
FIXED TIMEThe durations of red, green and all-red phases are fixed.
INTERNET CONNECTIVITYRemote control of portable traffic lights through the GSM network.
QUARTZ MODEUse the emergency mode when the radio communication is faulty.

Smart Traffic Control

Green on demand

When the Green on Demand function is activated, the master and slave units remain in the full red signal phase until a vehicle is detected on either unit. Once a vehicle is detected, the corresponding signal automatically switches to green, allowing traffic to flow.

This first-come, first-served system ensures efficient signal operation by reducing unnecessary waiting time and minimizing queuing. Green on Demand optimizes traffic flow throughout the day, dynamically adjusting to traffic density to provide seamless and efficient control in any scenario.

Durable and energy-efficient portable traffic lights designed for extended runtime of up to 25 days on a single charge.

Seamless Radio Communication

Safer roads

Our portable traffic lights feature advanced radio communication technology, ensuring synchronized operation even during interference.

This smart technology ensures safe, efficient traffic flow and highlights our commitment to reliability and safety.

Up to 25 Days on a Single Battery Charge

Superior Runtime, Ultimate Efficiency

Our portable traffic lights deliver up to 25 days of nonstop operation on a single battery charge, thanks to our energy-efficient design. Competitors’ models typically last only 7 to 18 days and often need two or three batteries, increasing costs and theft risks.

Unlike solar-powered options, which suffer from dust, wind instability, transport damage, and theft, our solution is robust and reliable.

Additionally, battery checks are required only every 15-20 days, reducing costs, CO2 emissions, and onsite interventions, ensuring safer and more efficient traffic management.

Galvanised Metal Housing

BUILT TO LAST

Our portable traffic lights are built to last, featuring durable galvanized steel housing for the battery box, foldable mast, and signal head.

Unlike competitors’ designs, which often rely on plastic or a mix of plastic and metal that can crack or break over time, our robust construction offers superior protection against water damage and direct impacts.

While plastic housings may shatter in a collision, our metal housing can bend while keeping the electronics safe, ensuring the system remains functional when it matters most.

Always connected,

always in control

Managing portable traffic lights has never been easier or more efficient than with our SPHERE Traffic Control web app. This innovative solution provides unmatched convenience, enabling users to monitor, manage, and control their portable traffic lights remotely—from the office, home, or on the go.

Intuitive Interface

simple IS BETTER

At SPHERE, we believe that Simple is Better. Our intuitive interface, with just three durable rotary knobs, ensures quick and easy operation in any conditions.

Unlike competitors’ touchscreens or keypads, which can break during transport, become unresponsive in cold conditions, or malfunction in dusty environments, our design is built for reliability and simplicity.

With SPHERE, workers can focus on the job without frustration or delays.

Increased Safety

MIRRORING function

The Mirroring Function enhances safety by allowing two portable traffic light units – one on each side of the road – to display the same signal information simultaneously.

This setup ensures that drivers, even in long queues or obstructed views caused by large vehicles, can clearly see the signals and react accordingly.

By meeting local safety requirements and improving visibility for all drivers, the Mirroring Function helps maintain a safer and more efficient work zone environment.

DAISY CHAIN

The Daisy Chain Operating Mode connects up to seven portable traffic lights, ensuring efficient regulation at T-junctions, crossroads, roundabouts, or multi-entrance zones. Each unit alternates in the GREEN phase while others remain in RED, providing safe and reliable transitions for complex projects.

flexibility in color

perfect for every project

Our portable traffic lights are available in three standard colors – orange, yellow, or gray – allowing you to choose the option that best suits your needs. For those requiring a unique look, custom paint jobs are also available upon request, offering flexibility to suit your specific branding or project requirements.
