Innovative Applications of Real-World Vehicle Trajectories Collected with a Radar Vehicle Detection System

Creator:: Simpson, Ellen J.
Abstract:: Left turn movements are considered to be the highest risk movements through an intersection, and can result in head on, angle, or side impact crashes. The flashing yellow arrow (FYA) for use as a permissive left turn phasing indication is relatively recent, first appearing in the 2009 edition Manual on...

Numerical Analysis of a Spine as a Retrofit of a Moment-Resisting Frame

Creator:: Rivera Torres, David M.
Abstract:: Steel moment-resisting frames (MRFs) are widely used in the United States to resist seismic forces. MRFs have many advantages, including architectural versatility, vetted member and connection detailing requirements, and high ductility for special MRFs (SMRF). However, MRFs require large members to meet story drift criteria. Moreover, strong-column-weak-beam requirements can result...
