An active way to boost traffic flow
A futuristic scheme is to be trialled on the M42 in Birmingham, using a combination of hi-tech traffic management systems, to help smooth traffic flow and reduce congestion. From summer 2004, a series of innovative tools will start to be integrated as part of the Active Traffic Management project. Helping to provide safer, smoother and more... view more... (2003-12-01)
Gas explosions: A new way to study phantom traffic jams
A University of Alberta researcher has devised a new theoretical approach to studying phantom traffic jams. Normally a traffic tie-up happens when vehicles reach a bottleneck and traffic flow is reduced, or in the case of an accident, halted completely. view more (2009-06-09)
VIDEO IMAGES COULD HELP SPEED UP CITY TRAFFIC
Current methods of traffic control are normally based on inductive loops placed in the road on approaches to traffic lights, to sense the presence of approaching vehicles. Inductive loops are expensive to install and are prone to damage, while also giving limited information about traffic conditions. view more (1999-09-14)
Traffic jam mystery solved by mathematicians
Mathematicians from the University of Exeter have solved the mystery of traffic jams by developing a model to show how major delays occur on our roads, with no apparent cause. view more (2007-12-19)
Safer skies for the flying public
University of Texas professor Constantine Caramanis and colleagues at the Massachusetts Institute of Technology (MIT) are working on a air traffic decision-making system that rapidly adapts its flight recommendations without human input based on thousands of changing variables. view more (2008-09-04)
Departure time choice determines congestion
Improved traffic planning with dynamic traffic models To gain insight into the expected traffic congestion on Dutch roads, it is necessary to take into account the moment of departure of the Dutch driver. This moment can be determined by using indirect observation and mathematics. This is one of the conclusions from the research of Karel Lindveld,... view more... (2003-08-29)
Go with the flow
Traffic flows account for as much as one-third of global energy consumption. But unconventional changes in managing traffic flow could significantly reduce such waste and lower harmful CO2 emissions, says Dirk Helbing. view more (2007-11-16)
Molecular mechanism provides intra-cellular traffic signal
Researchers at the University of Illinois at Chicago have found that intra-cellular trafficking is tightly coordinated for maximum flow through cellular compartments - much as vehicles on a crowded road are allowed to pass quickly through a succession of green traffic lights. view more (2006-10-18)
Irish airport to take part in the EGNOS system
On 24 July, ESA signed a contract with the Irish Aviation Authority to install satellite navigation equipment at Cork airport in Ireland. This will form part of EGNOS, Europe's first venture into satellite navigation and the first step on the way to Galileo, Europe's own satellite navigation system which is a joint initiative of the European... view more...

Study: When local revenue falls, traffic citations go up
Got a lead foot? Hold on to your wallet. A new study to be published in next month's Journal of Law and Economics finds statistical evidence that local governments use traffic citations to make up for revenue shortfalls. So as the economy tanks, motorists may be more likely to see red and blue in the rearview. view more (2009-01-13)
Infection with toxoplasmososis increases the risk of being involved in a road traffic accident
A new study published in BMC Infectious Diseases reveals that people with latent toxoplasmosis (a harmless form of the disease) are more likely to be involved in a road traffic accident. These findings may well be due to the presence of cysts formed in nerves and muscle tissue, which may reduce the ability of infected individuals to concentrate.... view more... (2002-08-05)
Driving Under the Influence (of Stress): Regional Effects of 9/11 Attacks on Driving
The September 11 terrorist attacks had a profound impact on this country's psyche. Eight years after the attacks, we are still learning how those terrible events affected us. view more (2009-02-03)
Where rubber meets the road
Intelligent tyres, where a vehicle is controlled by a combination of the satellite Global Positioning System and the tyre-road contact patch may be a thing of the future, but steps towards this will be described on Thursday 7 December at the Institute of Physics Conference, ‘Where Rubber Meets the Road’. Improvements in materials and... view more... (2000-12-05)
Risk models can reduce number of collisions with wild animals
Hundreds of thousands of animals are killed in traffic every year. The threat traffic represents to badgers is greater than was previously known. A new dissertation at the Swedish University of Agricultural Sciences (SLU) illuminates the conflict between traffic and animals in Sweden and provides models that predict the risk of accidents involving... view more...

The Olympic fleet
The traffic chaos in Athens is notorious. To avoid gridlock during the Olympic Games, the "Eye in the Sky" uses helicopters to record the traffic from the air. On the ground, some vehicles notify the system of their state of progress. Up-to-date information is available to everyone. --- Researchers at the Fraunhofer Institute for... view more...

This grass is still greener
In areas of the U.S. where golfers can enjoy the game year-round, winter temperatures, foot and equipment traffic, and frost can wreak havoc on healthy greens and present challenges for course managers and owners. view more (2009-02-27)
Letting the spin loose
Two properties of an electron-its spin and its charge-are generally thought to be inseparable, intrinsic characteristics, no more given to sudden changes or going off on their own than say, the fur on a cat or the paint on a bicycle. But a team of scientists at the Weizmann Institute of Science has recently demonstrated conclusively that, in very... view more... (2005-07-13)
New Computer Model will help local authorities follow the green approach
Researchers in the UK have developed a new way to model on a computer the patterns of energy use and pollution emissions in urban areas. The new method will help local authorities to plan long-term strategies for reducing energy consumption and pollution. The modelling system is now being extended to include social considerations, such as... view more... (2001-08-30)
Research gives new meaning to 'green' cross code
Pedestrians could reduce the amount of traffic pollution they breathe in simply by crossing the street, according to the latest research from the University of Leeds. view more (2009-10-05)
UCSB researchers discover that the cell's endosomes use a surprising transportation system
