MPC Research Reports
View AllBridge inspection is an important phase in bridge management. In 2009, a joint American Society of Civil Engineers Structural Engineering Institute and AASHTO Ad-Hoc group was created to identify the issues in bridge safety and to study current bridge practices. This group recommended: "A more rational... Concrete has been used in dams, bridges, and highway pavements in which freeze-thaw process and cyclic loading are considered as important factors affecting its mechanical behavior during its service life. Damage caused by frost expansion is a primary concern when designing concrete structures in cold... This research presents network analysis tools for estimating bicycle demand and bicycle volumes on a transportation network. There are three main procedures used in the development of the network analysis tools: an initial bicycle origin-destination (O-D) demand generation procedure, a bicycle traffic... This report presents a research examining the feasibility of creating an integrated structural health monitoring and impact/collision detection system for bridges in remote cold regions, where in-person inspection becomes formidable. The research report includes a theoretical analysis of the impact event... While high income represents one path to resilience, our results suggest higher resilience in locations with proximity to high levels of employment, with more compact and connected street networks that facilitate walking and bicycling, and/or with better transit infrastructure. Current transit usage... Scour of spill-through abutments occurs due to the combined influence of geotechnical and hydraulic processes. The present study is among the first to address the geotechnical process associated with the failure of the compacted earth, spill-through abutments, and the effects of the geotechnical strength... Conventional test methods for roadway compaction cover less than 1% of roadway; whereas, intelligent compaction (IC) offers a method to measure 100% of a roadway. IC offers the ability to increase compaction uniformity of soils and asphalt pavements, which leads to decreased maintenance costs and an... Automated vehicles promote road safety, fuel efficiency, and reduced travel time by decreasing traffic congestion and driver workload. In a vehicle platoon (grouping vehicles to increase road capacity by managing distance between vehicles using electrical and mechanical coupling) of such automated vehicles... In intelligent transportation systems, most of the research work has focused on lane change assistant systems. No existing work considers minimizing the disruption of traffic flow by maximizing the number of lane changes while eliminating the collisions. In this thesis, we develop qualitative and quantitative... The growing uncertainty about oil prices and availability has made long-range transportation planning more challenging. Rather than relying on trend extrapolation, this study uses market mechanisms to evaluate key long-range transportation planning assumptions. Although the Washington Department of Transportation... |
