Detection, Monitoring & Machine Vision

Two decades after the death of the inductive loops was predicted, Matt Zinn, technical services manager at Eberle Design says the technology still offers advantages. More than 20 years ago the emergence of video detection systems led many to foretell the end of inductive loops. In the intervening years advocates of radar, infrared and wireless detection technologies have also claimed that loops were on their way out. But in fact, by all calculations, the use of loops has actually increased and although

When Texas A&M Transportation Institute was asked to devise a temporary traveller information system for work zones, it started by asking drivers what they need. Robert Brydia explains the thinking, implementation and results. US Interstate 35 (I-35) runs roughly north–south originating in Laredo, Texas and ends 1,500 miles away in Duluth, Minnesota having passed through Oklahoma, Kansas, Missouri and Iowa. Within Texas the I-35 splits into I-35E and I-35W passing through Dallas and Fort Worth respectiv

Jason Barnes looks at where the detection and monitoring sector is heading. In the future, there will be no such thing as an un-instrumented road. Just a short time ago, that could have been a quote from a high-level policy document but with the first arrivals of vehicles with 802.11p connectivity – the door-opener to Vehicle-to-X (V2X) applications – it’s a statement which has increasing validity. The technology which uses our roads will also provide information on road conditions but V2X isn’t the only

Indonesia has started tackling acute traffic congestion in Jakarta and Surabaya. When talking about Jakarta, Indonesia’s economic, cultural and political centre, it is very easy to lapse into superlatives. With a population of over 10 million people it is the thirteenth most populated city in the world and the biggest in South East Asia. The official metropolitan area, known as Jabodetabek, is also the second largest in the world. Almost 98% of journeys in Jabodetabek are made by road and the tremendous

Flir’s open architecture video detection management software, Flux, enables users to scale the system to their own requirements, says the company. Flux, an intelligent software platform for use with a Flir video detection system, collects traffic data, events, alarms and video images generated by the video detectors, to manage and control all traffic information generated by multiple detectors and provide the user with meaningful and relevant data. The web-based graphical user interface provides event alert

Videotec’s remote controlled pan tilt zoom (PTZ) cameras from are suitable for marine applications, industrial atmospheres or road tunnels. The range includes day/night cameras and dual vision solutions with thermal imaging. Images can be transmitted over a local area network or the internet using H.264/AVC compression, compatible with ONVIF protocol Profile S.

The latest real-time interactive 3D VR simulation system from Forum8 is designed to improve the way CCTV images are used, and, said the company, is suitable for monitoring traffic/pedestrian flow in real time. VR-StreetView embeds links to the individual camera positions in an interactive 3D model of the target area. Operators can click on any one of the camera icons embedded in the model and a window will open showing live feed from the relevant camera, enabling operators to see precisely where the inci
