Research Highlights

Application of LRFD Principles for Deep Foundations in Oregon: Phase 1

Trevor Smith
Peter Dusicka
Project Sponsor Champion: Bruce Johnson, ODOT State Bridge Engineer . The Oregon DOT has routinely relied on the use of the Wave Equation Analysis of Piles (WEAP) software to dynamically model the bridge pile driving installation operation. Either from the end of initial driving (EOID) when the pile reaches design penetration, or a later Beginning of Restrike (BOR) by the driving hammer, the ODOT has become proficient at establishing axial capacity based on WEAP results. This removed the ... Read More

Fusion and Integration of Arterial Performance Data

Kristin Tufte
Real-time knowledge of system performance enables transportation agencies to manage traffic conditions and keep the public informed of periods of congestion. The ability to accurately measure arterial performance has been limited primarily by the availability of appropriate and reliable data. Unlike freeway networks where speed, flow, and occupancy measures are generally sufficient to quantify the performance of the link, the link-node combination of interrupted-flow arterial facilities requi...
