KAIST Professor Finds Paradox in Human Behaviors on Road -Strange as it might seem, closing roads can cut delays A new route opened to ease traffic jam, but commuting time has not been reduced.Conversely, motorists reached their destinations in shorter times after a big street was closed. These paradoxical phenomena are the result of human selfishness, according to recent findings of a research team led by a KAIST physics professor. Prof. Ha-Woong Jeong, 40, at the Department of Physics, conducted a joint research with a team from Santa Fe Institute of the U.S. to analyze the behaviors of drivers in Boston, New York and London. Their study found that when individual drivers, fed with traffic information via various kinds of media, try to choose the quickest route, it can cause delays for others and even worsen congestion. Prof. Jeong and his group"s study will be published in the Sept. 18 edition of the authoritative Physical Review Letters. The London-based Economist magazine introduced Prof. Jeong"s finding in its latest edition. Prof. Jeong, a pioneer in the study of "complex system," has published more than 70 research papers in the world"s leading science journals, including Nature, PNAS and Physical Review Letters. "Initially, my study was to reduce annoyance from traffic jam during rush hours," Prof. Jeong said. "Ultimately, it is purposed to eliminate inefficiency located in various corners of social activities, with the help of the network science." The Economist article read (in part): "...when individual drivers each try to choose the quickest route it can cause delays for others and even increase hold-ups in the entire road network. "The physicists give a simplified example of how this can happen: trying to reach a destination either by using a short but narrow bridge or a longer but wide motorway. In their hypothetical case, the combined travel time of all the drivers is minimized if half use the bridge and half the motorway. But that is not what happens. Some drivers will switch to the bridge to shorten their commute, but as the traffic builds up there the motorway starts to look like a better bet, so some switch back. Eventually the traffic flow on the two routes settles into what game theory calls a Nash equilibrium, named after John Nash, the mathematician who described it. This is the point where no individual driver could arrive any faster by switching routes. "The researchers looked at how this equilibrium could arise if travelling across Boston from Harvard Square to Boston Common. They analysed 246 different links in the road network that could be used for the journey and calculated traffic flows at different volumes to produce what they call a “price of anarchy” (POA). This is the ratio of the total cost of the Nash equilibrium to the total cost of an optimal traffic flow directed by an omniscient traffic controller. In Boston they found that at high traffic levels drivers face a POA which results in journey times 30% longer than if motorists were co-ordinated into an optimal traffic flow. Much the same thing was found in London (a POA of up to 24% for journeys between Borough and Farringdon Underground stations) and New York (a POA of up to 28% from Washington Market Park to Queens Midtown Tunnel). "Modifying the road network could reduce delays. And contrary to popular belief, a simple way to do that might be to close certain roads. This is known as Braess’s paradox, after another mathematician, Dietrich Braess, who found that adding extra capacity to a network can sometimes reduce its overall efficiency. "In Boston the group looked to see if the paradox could be created by closing any of the 246 links. In 240 cases their analysis showed that a closure increased traffic problems. But closing any one of the remaining six streets reduced the POA of the new Nash equilibrium. Much the same thing was found in London and New York. More work needs to be done to understand these effects, say the researchers. But even so, planners should note that there is now evidence that even a well intentioned new road may make traffic jams worse."

Research University Presidents Discuss Global Network to Increase Cooperation Presidents and leaders of research universities participating in the 2008 International Presidential Forum on Global Research Universities (IPFGRU) held at the Westin Chosun Hotel in Seoul, Korea on Sept. 8, 2008 exchanged views and ideas on how to build and effectively utilize a global research network in order to increase cooperation and exchanges among institutions of science and technology across the world. The participants agreed on the need to promote the sharing of expertise and facilities, conduct joint researches and positively implement dual degree, roaming professorship and other programs that help institutions in societies at different stages of scientific and technological development maximize the fruits of their research activities. As a major goal, the participants agreed to create alliances for research and education that can become a new paradigm for global cooperation, with the outcome of discussions at the 2008 IPFGRU providing the guidelines for future endeavors in this direction. Through the day-long symposium, participants reached general agreements on the following points: --The concept of sharing faculty or roaming professorship should be actively promoted in order to accelerate global dissemination of academic expertise with the institutions and state authorities concerned easing existing restrictions to such arrangements and ensuring maximum academic freedom of professors involved. --Dual degree programs especially those involving institutions of different countries need to be further encouraged in view of their benefits of resources sharing, expansion of knowledge and cultural exchanges and that educational authorities should try to remove various forms of limitations. --As competitions over university ranking would grow intensive as institutions seek to attract better students and more donations, there is need to institutionalize a fairer, globally recognized national, regional and international assessment systems. --In view of rapid expansion of interdisciplinary researches which calls for the sharing of facilities and expertise among different institutions, it is necessary to establish national or regional hubs to make state-of-the-art facilities and equipment available for researchers and research programs experiencing limitations in financial and material resources. --National governments and political leaders should better recognize the importance of science and technology for societal and global prosperity and the science and technology community needs to make more communicative approaches to politicians so that greater trust may be built between them. --Arrangements to conduct joint research involving international industries, academia and government should be accelerated with a view to addressing the common problems facing the mankind in the 21st century, including energy, environment, water, food and sustainability. The United Nations and other international organizations need to provide stronger support for research universities’ efforts in this direction. --Research universities across the world should make concerted efforts to establish a global cooperative network that can facilitate the flow of information, resources and research personnel to realize universal advancement of science and technology and, ultimately, enhance the quality of human life.

World Research University Heads To Discuss Global Networking at KAIST Symposium About 70 leaders of the world"s major research universities will discuss how to strengthen and operate global networks to share faculty, students, facilities and other resources for common advancement at a symposium Monday, Sept. 8, at the Westin Chosun Hotel in Seoul organized by KAIST, Korea"s foremost institute of science and technology education and research. Participants of the 1st International Presidential Forum on Global Research Universities are from 39 universities in 20 countries. They include nine presidents of Korean universities. The international symposium, the first such event to be held in Korea, will proceed in five panel sessions. The subjects of each session and their keynote speakers are: -- "Roaming Professorships: To Whose Benefit?" by Dr. John Anderson, president of the Illinois Institute of Technology, USA,-- "Dual Degree Programs: Future Potential and Challenges" by Dr. Paul Greenfield, president of the University of Queensland, Australia, -- "Sharing Facilities and Expertise" by KAIST President Nam Pyo Suh,-- "An Approach to Joint Research Ventures with NASA" by Yvonne Pendleton, NASA, and-- "Globalization through Interfacing with Existing Networking" by Dr. Lars Pallesen, rector of the Technical University of Denmark. KAIST President Suh said of the purpose of the conference: "Research universities have become global enterprises. Collaborations that were once primarily between individual researchers are now increasingly occurring at institutional and international levels. Similarly, educating students which used to be the responsibility of a single university has now become a multi-institutional undertaking, involving many universities in different countries. "Now leading research universities in many countries depend on the continuous supply of outstanding graduate students from the "feeder" schools of developing nations. There are concerns that the current system may not be serving the interest and need of some institutions, especially those in developing nations. This should be examined and understood to devise international mechanisms that can accentuate the positive aspects of globalization. "Through this forum, we hope to forge an international network of universities that will strengthen the effort of individual universities and create alliance for research and education that can become a new paradigm for global collaboration." Prime Minister Han Seung-soo will give a speech at a dinner after the conclusion of the symposium. President of the Korea International Traders Association Lee Hee-beom will make a welcoming address at the start of the conference. Co-sponsors of the international university presidents" forum include the Dong-a Ilbo, a major national daily, and the Dong-a Science magazine.
