(Press-News.org) BEER-SHEVA, Israel, January 4, 2013 -- Ben-Gurion University of the Negev (BGU) researchers reveal that data culled from geosocial networks like the GPS traffic app Waze can help prevent traffic incidents with better deployment of police resources at the most accident prone areas.
"Only now are we beginning to discover the potential in the huge amount of data collected daily," explains BGU researcher and Ph.D. student Michael Fire. "Studies of this kind, which monitor events such as traffic accidents over time, can help the police identify dangerous sections of roads in real time, or alternatively, locations where few police are needed."
The paper, "Data Mining Opportunities in Geosocial Networks for Improving Road Safety," was presented at the IEEE 27th Convention of Electrical and Electronics Engineers in Israel.
Waze records location data and enables users to upload and share comments on any detail, including traffic alerts, accidents or police presence. According to its Web site, Waze has 30 million worldwide users and describes itself as "a community-based traffic and navigation app whose users share real-time traffic and road info, saving time and gas money."
Using Waze data and Google Earth, the BGU researchers determined that three-quarters (75 percent) of the locations in Israel with the highest number of accidents were intersections. They then analyzed references to a police presence to determine if the police were present at the spots that had the worst traffic accidents.
"There were numerous instances where the police were manning quieter intersections, while busier intersections went unmonitored," Fire explains. "According to the data, police response time varied from 20 minutes to 40 minutes in some situations."
Using Waze, data from May and June 2012 was collected and analyzed on accident reports, police presence, traffic jams, and speed traps. BGU researchers identified 579 different locations in Israel that had at least five reoccurring accidents during this time where 5,156 reported accidents occurred. Police were reported at least 15 times at more than 3,500 locations.

American Associates, Ben-Gurion University of the Negev (AABGU) plays a vital role in sustaining David Ben-Gurion's vision, creating a world-class institution of education and research in the Israeli desert, nurturing the Negev community and sharing the University's expertise locally and around the globe. With some 20,000 students on campuses in Beer-Sheva, Sede Boqer and Eilat in Israel's southern desert, BGU is a university with a conscience, where the highest academic standards are integrated with community involvement, committed to sustainable development of the Negev. AABGU is headquartered in Manhattan and has nine regional offices throughout the U.S. For more information, please visit www.aabgu.org.
For almost 30 years, researchers have sought to identify a particular enzyme that is involved in regulating electron transport during photosynthesis. A team at Ludwig-Maximilians-Universität (LMU) in Munich has now found the missing link, which turns out to be an old acquaintance.
Photosynthesis sustains life on Earth by providing energy-rich compounds and the molecular oxygen that higher organisms depend on. The process is powered by sunlight, which is captured by "biochemical solar cells" called photosystems that are found in plants, algae and certain types of bacteria. ...
Calcium is so much more than the mineral that makes our bones and teeth strong: It is a ubiquitous signaling molecule that provides crucial information inside of and between cells. Calcium is used to help our hearts beat regularly, our guts to function appropriately and even for fertilization to occur. It is also needed to help muscles and blood vessels contract, to secrete hormones and enzymes and to send messages throughout the nervous system.

However, Francis Chaouloff, research director at Inserm's NeuroCentre Magendie (Inserm Joint Research Unit 862, Université Bordeaux Ségalen), Sarah Dubreucq, a PhD student and François Georges, a CNRS research leader at the Interdisciplinary Institute for Neuroscience (CNRS/Université Bordeaux Ségalen) have just discovered the key role played by a protein, the CB1 cannabinoid receptor, during physical exercise. In their mouse studies, the researchers demonstrated that the location of this receptor in a part of the brain associated with motivation and reward systems controls ...

Vegetated drainage ditches can help capture pesticide and nutrient loads in field runoff, U.S. Department of Agriculture (USDA) scientists report. These ditches—as common in the country as the fields they drain—give farmers a low-cost alternative for managing agricultural pollutants and protecting natural resources.
Agricultural Research Service (ARS) ecologist Matt Moore at the agency's National Sedimentation Laboratory in Oxford, Miss., and his colleagues conducted the research. ARS is USDA's chief intramural scientific ...

What is normal to most people in winter has so far been impossible in physics: a minus temperature. On the Celsius scale minus temperatures are only surprising in summer. On the absolute temperature scale, which is used by physicists and is also called the Kelvin scale, it is not possible to go below zero – at least not in the sense of getting colder than zero kelvin. According to the physical meaning of temperature, the temperature of a gas is determined by the chaotic movement of its particles – the colder the gas, the slower ...
New research from Western University provides brain imaging evidence that students well-versed in very basic single digit arithmetic (5+2=7 or 7-3=4) are better equipped to score higher on the Preliminary Scholastic Aptitude Test (PSAT), an examination sat by millions of students in the United States each year in preparation for college admission tests.
In findings published today in The Journal of Neuroscience research led by Daniel Ansari, Associate Professor in Western's Department of Psychology and a principal investigator at the Brain and Mind Institute, showed by ...
The U.S. Defense Advanced Research Projects Agency (DARPA) recently selected Southwest Research Institute to provide the flight low-rate crosslink wireless communications platform for the System F6 Program.
The System F6 Program, which is envisioned to culminate in an on-orbit demonstration in 2015–2016, is designed to validate a new space mission concept in which a cluster of smaller, wirelessly connected spacecraft replaces the typical single spacecraft carrying numerous instruments and payloads. This "fractionated" architecture enhances survivability, responsiveness ...
BOSTON – Genomic research is widely expected to transform medicine, but progress has been slower than expected. While critics argue that the genomics "promise" has been broken – and that money might be better spent elsewhere -- proponents say the deliberate pace underscores the complexity of the relationship between medicine and disease and, indeed, argues for more funding.
But thus far, these competing narratives have been based mostly on anecdotes. Ramy Arnaout, MD, DPhil, a founding member of the Genomic Medicine Initiative at Beth Israel Deaconess Medical Center (BIDMC), ...
UNIVERSITY PARK, Pa. -- The amount of rainfall affects the number of infant infections leading to hydrocephalus in Uganda, according to a team of researchers who are the first to demonstrate that these brain infections are linked to climate.
Hydrocephalus -- literally "water on the brain" -- is characterized by the build-up of the fluid that is normally within and surrounding the brain, leading to brain swelling. The swelling will cause brain damage or death if not treated. Even if treated, there is only a one-third chance of a child maintaining a normal life after post-infectious ...
UNIVERSITY PARK, Pa. -- Norfolk Southern Railway No. 999 is the first all-electric, battery-powered locomotive in the United States. But when one of the thousand lead-acid batteries that power it dies, the locomotive shuts down. To combat this problem, a team of Penn State researchers is developing more cost-effective ways to prolong battery life.
The experimental locomotive's batteries, just like automotive batteries, are rechargeable until they eventually die. A leading cause of damage and death in lead-acid batteries is sulfation, a degradation of the battery caused ...
