Multiphase Adaptive
Detection System (ADS)

SRL’s Adaptive Detection System is so intelligent and adaptive it can manage daily traffic flows by making automatic adjustments of green times easily, it does this by using deep learning algorithms to interpret the data received from our new high accuracy radar detector (traffic/volume/speed).

It is important whether it is planned and unplanned works not only getting equipment on-site & set up quickly but safely and efficiently too.

The need for reliable equipment that is easy to set up is vital in this industry. The SRL range of portable traffic lights and pedestrian units meets all these needs with ease.

Adaptive Detection System With
Advanced Radar Detection

The Adaptive Detection System is incredibly easy to set up for rapid deployment. Once the system is set up it begins to optimise max set timings, adding time to each approach when it has reached its saturation point. The system also allows for HGV start lag (HGVs slow off the mark) allowing extra time to get moving and clear the site. Once the system has seen morning peak and evening peak the system is fully optimised, however still has the ability to make dynamic changes when required.

The Adaptive Detection System is also compatible with a wide range of products, including all portable, UTMC, temporary and haul route crossing systems.

How Does It Work?

Multiphase ADS works by connecting a high accuracy radar detector (which collects vital data about real time traffic volumes and speeds at the roadside) to temporary traffic lights using a clever algorithm that adjusts the green time at traffic lights for optimum traffic management.

The busier the road, the greater the benefit from using this unique technology, which also takes into account site-specific factors like HGV lag.

SRL’s Multiphase ADS is especially effective in areas with tidal traffic flow because of its ability to reduce the build-up of traffic moving in a single direction. Once peak flow has diminished and congestion eases, this dynamic system adjusts the green time to reflect the quieter traffic conditions

Benefits For Road Users

Confident in the ability of our product to reduce congestion we looked to substantiate our in-house findings, so we asked independent consultants and industry experts at IRConsultancy/ Bryan G Hall to conduct an objective study of the system using traffic flow data and Vissim with 3-way control, in a heavily saturated tidal flow location in Yorkshire. Over a one hour period at the test junction with 3 way control, the impact of replacing basic logic with SRL’s Multiphase ADS was:

50%

Reduction in average queue length

29%

Reduction in maximum queue length

22%

Reduction in average journey time at the junction

40%

Increase in reduction in average journey time during peak flow (between 8.40am and 9.00am across all routes)

52%

Reduction in journey time for the route with the highest flow of traffic(North to South in the study)

SRL’s innovative Multiphase ADS provides a genuine solution to the problem of congestion around temporary road works. It is the only product able to offer 2, 3 and 4 way control.

Key Features

  • Rapid installation (only basic timings required)
  • No site visits to make timing alterations
  • 50% more efficient than standard signals
  • False start rectification (no stuck reds from vehicles failing to move first time)
  • Adapts to present traffic conditions
  • Can be used up to 4-way control

Reduce Delays

Reduce Delays

During a site test - within 20-30 minutes of swapping correctly timed SRL traffic lights (with a back up of traffic up to 100-130+meters) with our Adaptive Detection System both sides of the delays were gone.

Special System

Special System

Our Adaptive Detection System has the ability to run as a Special System which allows compatibility with PEDs. Increasing utilisation our ADS system can be used with everything.

Our ADS System is reactive, intelligent traffic light technology that is fully portable and gives flexibility and ease of use.

What Our Customers Say About ADS

“SRL’s ADS system was a huge advantage for us during the tender stage. Fully portable and flexible for our needs, the reactive, intelligent traffic light technology is 50% more efficient than standard signals. All 70 of SRL’s traffic signals for the Scottish Water contract are ADS enabled.”
