The Southeast's rural two-lane highways are the deadliest roads in the nation, according to a recent Georgia Institute of Technology study. The most frequent crashes occurred on these highways, especially in wooded areas where drivers ran off the road and hit trees.
Researchers found that marked crosswalks increase the risk of injury for older adults, who face a 3.6 times greater risk when crossing at intersections without traffic signals or stop signs. The study suggests that older pedestrians should avoid relying on marked crosswalks and instead use signals or signs to identify safe crossing areas.
Recent trends in motorcycle fatalities show older riders are more likely to be involved in fatal crashes, often on rural roads. Over half of all motorcycle fatalities involve collisions with other vehicles.
Researchers aim to optimize internet traffic flow by allocating available capacity fairly among competing packets of information. A new algorithm developed could be applied to various networks, including telephone systems and power grids.
A new study led by Dr. Don Redelmeier found that people overestimate the speed of vehicles in the next lane, leading to unnecessary lane changes. Staying in one's lane is safer and achieves similar travel times as more aggressive driving.
A new University of Washington cable television channel, Traffic TV, will broadcast real-time rush-hour traffic updates starting June 1. The service provides live video footage of traffic choke points and estimated travel speeds along area highways.
