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.

PEDESTRIAN DETECTION

The AGD range of pedestrian detection products features CW Doppler radars for the detection of moving pedestrians and cyclists on crossings. AGD utilise Enhanced 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.

DIGITAL VISION PEDESTRIAN DETECTORS

The AGD640 is the latest digital vision detector for detecting waiting pedestrians or cyclists waiting to cross a carriageway. The dual optical system of this detector is designed to view a detection zone adjacent to the pole to which it is mounted.

The AGD640 uses both ambient light and its own infra-red illumination system to perform a twenty-four hour detection function in conditions ranging from bright sunlight to urban night-time.

In enhanced mode the zone size is 3m x 2m with a high level of shadow rejection. Pedestrians that are waiting to cross in the designated zone will generate a detect state.

The integrated vision sensors and processing utilise the AGD Livewire based platform to adapt the detector’s performance for a given installation. AGD Livewire provides the facility to adjust the zone size, presence and hold time. The AGD640 is supplied fully bluetooth and serial cable livewire enabled offering the added benefits of detector parameter adjustment and maintenance from the safety of ground level.

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 on the AGD website 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 RS422 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.
