Guidance for the Selection, Use, and Maintenance of Cable Barrier Systems
Friday, September 14th, 2012
NATIONAL COOPERATIVE HIGHWAY RESEARCH PROGRAM
Cable barriers are longitudinal roadside devices used to contain and/or redirect errant vehicles that depart the roadways. These barriers gradually redirect or arrest an impacting vehicle by stretching of the cables, minimizing forces on the vehicle and its occupants. While cable barriers have been used on U.S. highways for more than 60 years, their use has been on the rise and is expected to increase in the future.

Thursday, September 6th, 2012Most Minnesota motorists start to merge in construction zones as soon as they see warning signs and learn which lane ahead is closed. This driving behavior, called “early merge” can lead to dangerous lane switching, inconsistent driving speeds that cause crashes, long back-ups that block interchanges, and road rage. Research shows, however, that these dangers […]

Thursday, August 23rd, 2012
SAFETY IDEA PROGRAM
The goal of this Safety IDEA project was to develop a non-contact sensing platform to monitor the physiological signals of drivers such as the electrocardiography (ECG) and/or electroencephalography (EEG), from which the on-set and extent of drowsiness can be detected. Clinical research has found physiological signals are good indicators of drowsiness. Conventional bioelectrical signal measurement system requires the electrodes to be in contact with the human body. That not only interferes with the normal driver operation, but also is not feasible for long term monitoring purposes. Therefore, a non-contact physiological signal sensing platform as developed in this project will be very helpful to detect driver drowsiness and reduce crashes. Such sensors can be integrated readily into a wireless health monitoring system for drivers.
