Engineering the road to safer streetlighting

10.12.2002


An innovative engineering project could lead to fewer night-time accidents on badly lit roads.



It is developing a revolutionary way of assessing whether roads are equipped with appropriate levels of streetlighting.

The new assessment system is quicker, cheaper and more comprehensive than methods previously used. It can also help local authorities avoid the cost of unnecessary streetlight replacement.


The project is being carried out by engineers at Queen’s University Belfast with funding from the Swindon-based Engineering and Physical Sciences Research Council.

The system incorporates automated techniques that the project team has already tested and used to assess the landing lights at Belfast International Airport.

Digital video cameras, light filters and light meters are fitted onto the roof of a car, which is then driven at normal speed down the stretch of road under investigation. Meanwhile, the global positioning system gives the car’s precise location and sensors provide information about the road’s contours. An on-board computer captures all the data, which is later processed in a laboratory. The data can then be used to aid decisions about whether any roads, or sections of road, need better lighting to make them safer for both motorists and pedestrians.

The project team, which is working closely with the Highways Agency and with local authorities, is led by Dr Gordon Dodds of the University’s Electrical and Electronic Engineering School. Innovative imaging projects being undertaken at the School are also permitting analysis of all forms of lighting used in traffic signalling, as well as the interaction of robots equipped with vision in complex environments.

There are three main measures of lighting: luminance (light that is reflected from objects), illuminance (light that is shone onto objects), and glare (the amount of light that shields the objects we are trying to see). The new assessment system is the first of its kind that can measure all of these on complex streets. It is particularly well suited to measuring light along roads with twists, turns and gradients.

“The aim is to provide a reliable assessment technique that enables streetlighting resources to be applied in the most effective and beneficial way,” says Dr Dodds. “For us, the new system represents the culmination of seven years’ work”.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
