AGD Systems - Traffic Information and Measurement Equipment

AGD offers a comprehensive range of detection products covering a wide range of applications in traffic and pedestrian control. The product range is targeted at reducing the costs of providing efficient inputs to traffic control and management systems. The latest advances in radar technology offer real time information on vehicle count and speed, occupancy and queues.

AGD also manufacture the most extensive range of nearside signals for Puffin, Toucan and Pegasus crossing strategies. A dedicated product selector is available on our website. Please use the link below to access this.

VEHICLE DETECTION

AGD’s range of vehicle detection products feature CW doppler radars, advanced digital radars and digital vision technology for the detection of moving and stationary vehicles. These are offered with rugged housings, making them suitable for roadside environments and for fixing to existing street furniture.

The vehicle detection products featured in the Detection Generics (DG) brochure can be used stand-alone or as part of a detection system. They provide relay outputs to local controllers or other key traffic data via RS485 interfaces. Enhanced features provide cost-effective and reliable detection information for intelligent traffic management.

RADAR DETECTION AND MONITORING OF VEHICLES FOR TRAFFIC APPLICATIONS

AGD offers a series of CW doppler radar detectors designed for the detection and monitoring of vehicles at signalled junctions, pedestrian crossing installations and other applications, where the detection of moving vehicles is required in a long zone extending from the detector. Ease of installation, deployment with existing street furniture, and the advantages of non-intrusive detection make these detectors a cost-effective solution in urban environments.

INTELLIGENT TRANSPORT SYSTEM CAPABILITIES

The advantages of non-intrusive detection technology are well known. AGD has invested in developing this economic approach for ITS-based solutions. The real-time information available from the radar includes:

• Speed
• Direction
• Occupancy
• Flow
• Queues
• Headway

This information can be routed through the network to the UTMC control centre. Detection information from the network is now presented compliant with the UTMC standards.

Deployment of these detection systems is enhanced by a choice of interface media, making wireless solutions a cost-effective choice. The AGD Janus family offers a host of connectivity and data storage options in a single compact housing. Link a Janus outstation to a roadside detector to add considerable functionality to your ITS-based system and benefit more from the existing infrastructure. This diverse product range with typical applications is featured in the Systems for ITS brochure.

PEDESTRIAN DETECTION

The AGD range of pedestrian detection products features CW doppler radars for the detection of moving pedestrians and cyclists on crossings. Digital vision technology for the detection of moving or stationary pedestrians and cyclists while waiting to cross is also available. These are used in conjunction with the extensive range of AGD nearside signals for Puffin and Toucan crossing strategies, which can be seen on the product selector on our website, which can be accessed using the link below. These products are also featured in the red NSS brochure.

DIGITAL VISION PEDESTRIAN DETECTORS

The latest AGD625 digital vision detector offers Bluetooth connectivity or the standard serial interface to provide a Livewire platform for zone set-up with PDA or laptop. The Bluetooth version offers the flexibility of zone set-up and adjustment from the safety of ground level.

The optical system of the AGD625, which supercedes the AGD620, is designed to view a detection zone adjacent to the pole to which it is mounted. The detector uses ambient light to view the zone and provides its own IR illumination of the zone in night-time conditions. Stationary pedestrians or those moving in the designated zone waiting to cross a carriageway will generate a detect state 24 hours a day in urban conditions.

The AGD625 detector provides twin CMOS sensors and a powerful 32-bit DSP processing platform to allow all image processing to be performed at the detector. The AGD625 also utilizes the latest sophisticated tracking algorithms for optimum detection of moving or stationary pedestrians in the set zone.
