Research Highlights

Prioritization for Seismic Retrofit with Statewide Transportation Assessment

Peter Dusicka
The bulk of the bridge inventory in Oregon was built prior to the current understanding of bridge response and prior to current understanding of the expected earthquake demands. While some bridges are being replaced due to other deficiencies, majority are expected to continue to stay in service for decades to come. Prioritization method is needed for deciding on bridge investment or for allocating the limited resources available. The overall goals of the research are to develop and apply a re... Read More

Bus Safety Performance Monitoring and Analysis

James Strathman
TriMet is beginning to implement a program to monitor and analyze safety performance. The proposed project would contribute to this program in several ways. First, a survey would be designed and administered to operators during their annual safety recertification training. The survey would recover perceptions and information on the various sources of safety risk that operators experience in their assigned work. Findings from the survey would then be related to information maintained in TriMet... Read More
