  1. US DOT Report Confirms Speed Not Major Accident Cause US Department of Transportation study finds only five percent of crashes caused by excessive speed. As lawmakers around the country continue to consider speed limit enforcement as the primary traffic safety measure, the most comprehensive examination of accident causation in thirty years suggests this focus on speed may be misplaced. National Highway Traffic Safety Administration (NHTSA) investigated 5,471 injury crashes that took place across the country between July 3, 2005 and December 31, 2007. Unlike previous studies automatically generated from computerized data found in police reports, researchers in this effort were dispatched to accident scenes before they were cleared. This allowed a first-hand comparison of physical evidence with direct interviews of witnesses and others involved in the incident. NHTSA evaluated the data to determine the factors most responsible for the collision. "The critical reason is determined by a thorough evaluation of all the potential problems related to errors attributable to the driver, the condition of the vehicle, failure of vehicle systems, adverse environmental conditions, and roadway design," the report explained. "The critical pre-crash event refers to the action or the event that puts a vehicle on the course that makes the collision unavoidable, given reasonable driving skills and vehicle handling of the driver." Overall, vehicles "traveling too fast for conditions" accounted for only five percent of the critical pre-crash events (page 23). More significant factors included 22 percent driving off the edge of a road, or 11 percent who drifted over the center dividing line. When driver error was the primary cause of a crash, researchers went further to identify the "critical reason" behind that error. Distraction and not paying attention to the road accounted for 41 percent of the errors. Ten percent of errors were attributed to drivers lacking proper driving skills and either freezing up or overcompensating behind the wheel. Eight percent were asleep, having a heart attack or otherwise incapacitated. A similar eight percent of errors were attributed to driving too fast for conditions and five percent driving too fast for a curve (page 25). The NHTSA findings are mirrored in accident statistics provided by the Virginia Department of Motor Vehicles. The agency's most recent report lists "speed too fast" as the driver error that caused 2.9 percent of crashes in 2007 (view chart, see page 19). More accidents -- 3.8 percent -- were caused in Virginia by drivers falling asleep or becoming ill behind the wheel. Another 14.6 percent were caused by bad weather such as fog, rain and snow. "Speed too fast" was a more significant factor -- 13.7 percent -- in fatal accidents, as compared to 18 percent of fatal accidents involving alcohol and 9.6 percent caused by sleepiness and fatigue (PDF File view full Virginia report in 1.9mb PDF format). In the NHTSA and Virginia reports, "too fast for conditions" does not mean exceeding the posted speed limit. A vehicle driving 10 MPH on an iced-over road with a 45 MPH limit would be traveling too fast for the conditions if it lost control, but it would not have exceeded the speed limit. The UK Department for Transport isolated cases where only the posted limit was exceeded and found that, "Exceeding speed limit was attributed to 3 percent of cars involved in accidents" (view UK report). "Four of the six most frequently reported contributory factors involved driver or rider error or reaction," the Road Casualties Great Britain 2007 report stated. "For fatal accidents the most frequently reported contributory factor was loss of control, which was involved in 35 per cent of fatal accidents."

  2. China's nine-day traffic jam stretches 100km (AFP) – 16 hours ago BEIJING — Thousands of vehicles were bogged down Monday in a more than 100-kilometre (62-mile) traffic jam leading to Beijing that has lasted nine days and highlights China's growing road congestion woes. The Beijing-Tibet expressway slowed to a crawl on August 14 due to a spike in traffic by cargo-bearing heavy trucks heading to the capital, and compounded by road maintenance work that began five days later, the Global Times said. The state-run newspaper said the jam between Beijing and Jining city had given birth to a mini-economy with local merchants capitalising on the stranded drivers' predicament by selling them water and food at inflated prices. That stretch of highway linking Beijing with the northern province of Hebei and the Inner Mongolia region has become increasingly prone to massive jams as the capital of more than 20 million people sucks in huge shipments of goods. Traffic slowed to a snail's pace in June and July for nearly a month, according to earlier press reports. The latest clog has been worsened by the road improvement project, made necessary by highway damage caused by a steady increase in cargo traffic, the Global Times said. China has embarked in recent years on a huge expansion of its national road system but soaring traffic periodically overwhelms the grid. The congestion was expected to last into mid-September as the road project will not be finished until then, the newspaper said. The roadway is a major artery for the supply of produce, coal and other goods to Beijing.

  3. SolarBotanic is a company which researches and specializes in an emerging tech dubbed biomimicry -- which seeks to mimic nature, and use nature-inspired methods to solve human problems. SolarBotanic is focusing on energy production, and, to that end, they've developed what they call Energy Harvesting Trees. The trees aren't "real," (they're just modeled on real ones); these are composed of Nanoleafs, which use nanotechnology designed to capture the "sun's energy in photovoltaic and thermovoltaic cells, then convert the radiation into electricity." They also have stems and twigs which house nano-piezovoltaic material which act as generators producing electricity from movement or kinetic energy caused by wind or rain. The company has several patents on the technology already, and are currently seeking partners for funding and development. We don't really have any details about what these fake trees look like -- but Thom Yorke's probably going to write a song about them.
