Research Highlights

Tools for Gusset Plate Evaluation, Phase 2: Strengthening

Christopher Higgins
Peter Dusicka
The collapse of the I-35W Bridge in Minneapolis, Minnesota has raised questions regarding the performance and possibly safety of steel truss bridges. The failure investigation indicated that the collapse was due to a design error in the gusset plates used to connect the truss members. The findings also recommend that evaluation of truss connections will be needed, which is a deviation from past practice where only members were considered. There are large numbers of steel truss bridge connecti... Read More

Modeling and Analyzing the Impact of Advanced Technologies on Livability and Multimodal Transportation Performance Measures in Arterial Corridors

Miguel Figliozzi
Christopher Monsere
This research proposes a novel approach to study the microscopic, intersection-level interactions of two advanced control technologies: SCATS adaptive traffic signal control and transit signal priority (TSP). These interactions will be studied using Powell Blvd (PB), which is a fully instrumented urban corridor in Portland, OR. The corridor is severely congested during peak periods and has low levels of service (LOS) for transit, and motor vehicles. and pedestrians. This research will mode... Read More
