One of every four U.S. highway bridges has known structural problems or exceeded its intended life-span. Most only get inspected once every one or two years; University of Maryland researcher has developed a new sensor that measures indicators of a bridge's structural health, such as strain, vibration, flexibility, and development of metal cracks; the sensors are expected to last more than a decade, with each costing about $20

Millions of U.S. drivers cross faulty or obsolete bridges every day, highway statistics show, but it is too costly to fix all these spans or adequately monitor their safety, says a University of Maryland researcher who has developed a new, affordable early warning system.

This wireless technology could avert the kind of bridge collapse that killed thirteen and injured 145 along Minneapolis’ I-35W on 1 August 2007, he says — and do so at one-one-hundredth the cost of current wired systems.

U.N./Brookings Meeting: Good Practices for Humanitarian Response in Complex Security Environments

To Stay and Deliver: Good Practice for Humanitarians in Complex Security Environments Tuesday, June 21, 2011, 9:00 am - 10:30 am The Brookings Institution, Falk Auditorium, 1775 Massachusetts Ave, NW, Washington, DC Humanitarian assistance providers have always acknowledged the risks inherent to their line of work, yet recent statistics demonstrate that this is a particularly hazardous time to be an aid worker. Within the past decade, casualty rates have tripled, reaching above 100 deaths per year. Since 2005, hundreds of major attacks have been reported on aid workers in Afghanistan, Sudan, Somalia and other countries, prompting aid agencies to limit their presence in areas where assistance may be most needed. In response to the growing tension between maintaining humanitarian access and ensuring humanitarians' safety, the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) has documented strategies and practices for upholding effective operations in high security risk contexts. On June 21, the Brookings-LSE Project on Internal Displacement will host the launch of the OCHA- commissioned study, "To Stay and Deliver: Good Practice for Humanitarians in Complex Security Environments," with a discussion exploring risk management strategies to protect humanitarian operations and personnel.
