Inductive Loop Cutting

Inductive loop cutting involves specific-depth cutting into the road surface to install cables and sensors used to monitor traffic volume and traffic flow, followed by resealing the surface. Inductive loops can detect when traffic passes, identify the type of vehicle and report the volume and speed of traffic.

Types of Loop Cutting

Motorway Midas

MIDAS (Motorway Incident Detection and Automatic Signalling) detector loops are placed in every trafficked lane of a motorway and spaced every 500 metres.
Loop detectors collect real-time traffic data such as vehicle count, speed and traffic volume. This is analysed by the roadside controllers and appropriate messages displayed on the VMS signs.

Traffic Counting Systems

One of the cornerstones of Automatic Counting System success is the ability to automate all counting irrespective of distance, location, and environment.
The remote electronic counting system records automatically without human intervention, monitoring 24 hours a day, 7 days a week and 365 days a year.

Traffic Signal Loop

Traffic Signals mainly operate with loop-based approach detection systems, accurately detecting peak traffic points throughout the day. Each Traffic Signal junction layout specification can vary from site to site, area to area. Loop Detectors commonly used at Traffic Signal intersections are: Stop-line Loops; Call-cancel Loops; Queue Loops; MOVA Loops; Scoot Loops; System D Loops (XYZ); Speed Discrimination / Speed Assessment Loops. The loops are pivotal in the control of congestion.

Piezo Sensor – Speed Detection

Another modern advance in underground detection technology is Speed Monitoring. Installations comprise of Piezo Sensors and loop detectors, precisely spaced within the trafficked lane to monitor vehicle speed. Most commonly used at Roadside Speed Enforcement Cameras.

Piezo Sensor – Weight Detection

To calculate weight detection, weigh in Motion Sensors are placed in the carriageway. These are commonly used to monitor Department of Transport regulations with regards to vehicle loaded weight, based off:

Axle count
Speed
Wheelbase

Piezo Sensor – Cyclist Detection

Piezo are installed on the carriageway or footway for Cyclist detection. Cycle and pedestrian monitoring solution documents usage, identifies trends, and supports a wider effort to build sustainable infrastructure with minimal carbon impact.

Customizable active information displays show daily and yearly cyclist activity, helping show appreciation for their contribution to a better environment and motivating residents to cycle more.

Bicycle and pedestrian monitoring technology detects and protects vulnerable road users in multi-modal environments via integration with traffic signals, active information, or safety warning signs.

Ice Detection

To detect adverse weather, temperature sensors are cored into the carriageway and connected to a weather station. The data collected can then be accessed by relevant parties via remote connection. Detection and warning of adverse weather enables reactive maintenance, whereas prediction enables proactive anti-icing operations in advance of the onset of forecast weather.
