Talking cars coming soon

Talking cars aren't science fiction anymore -- thanks to scientists who have developed a set of algorithms that will allow robotic cars of the future to communicate with each other to help avoid collisions.

An international team, led by Indian-origin scientists Dr Bhibhya Sharma and Dr Utesh Chand of the University of the South Pacific, has developed the mathematical equations which would also instruct robotic cars how to change lanes safely.

According to Dr Sharma, the series of mathematical equations would instruct robotic cars when and how to merge lanes, which could lead to less accidents and ease traffic congestions.

"Flocking is a biologically inspired technique and a strategy commonly used in robotics. One of the advantages of flocking is that robots can work together and achieve what would take individuals far longer," he said.

In fact, according to the scientists, each car will be controlled by a centralised brain guided by a series of algorithms.

The brains will talk to each other and instruct the cars to merge lanes and move in formation together. The team demonstrated the technique using computer simulation and is currently trialling it in two wheel robots.

Team member Dr Chand has said that the cars have targets they move towards and maintain and when the cars find themselves in a merging situation, one of them will be given the position of leader, the rest will follow.

The team has written equations for attraction towards the target, enabling cars to stay inside their lanes and avoid crashing into each other.

The challenge now is to allow the robot to automatically plan how to avoid crashing with the side of the road and cars travelling close by, they said.

World-Class Light Source at Brookhaven National Laboratory By 2012

The U.S. Department of Energy’s Brookhaven National Laboratory announced today that it is beginning construction of the conventional facilities at the National Synchrotron Light Source II (NSLS-II), a project that will advance energy research for the nation and create hundreds of jobs for Long Island over the next several years. Energy Secretary Steven Chu visited the laboratory earlier this year and announced $150 million from the American Recovery and Reinvestment Act for the facility, some of which went towards accelerating the construction of NSLS-II.
NSLS-II will be an advanced, highly optimized, third-generation medium energy storage ring that will provide sophisticated, new tools for discovery-class science – science that will enhance national and energy security and help drive abundant, safe, and clean energy technologies. The x-ray brightness and resolution of NSLS-II will be world leading, exceeding that of any other light source currently existing or under construction, and it will be 10,000 times brighter than the present light source at Brookhaven Lab.


Torcon, Inc., a New Jersey firm with many projects in New York State, has been chosen to construct the building that will house the accelerator ring, the largest component of the machine. Torcon estimates that 90 percent of the total construction contract cost of more than $170 million will be spent directly with Long Island contractors and suppliers. This phase of the facility’s construction is expected to last through 2012.
