Filter by Keyword93 report(s) found with management in the keywords field Highway assets, including traffic signs, traffic signals, light poles, and guardrails, are important components of transportation networks. They guide, warn, and protect drivers and regulate traffic. To manage and maintain the regular operation of the highway system, state departments of transportation... The current legally required two-year inspection interval for most bridges is not an efficient system for conducting inspections, because many bridges do not require inspections this frequently, while others would benefit from more frequent monitoring. The research presented herein is based on the premise... Maintenance management has relied heavily on collecting asset condition information to plan maintenance activities and budget allocation. Data collection is often conducted on a sampling basis because of resource constraints. There is thus a perceived need for the development of an effective sampling... Crashes of heavy trucks with bridge columns are random events with low probability of occurrence. In spite of the low odds, previous collision events have resulted in catastrophic partial or full collapse of bridges. AASHTO-LRFD Bridge Design Specifications requires bridge columns to be designed for... Traffic congestion mitigation is one of the key challenges that transportation planners and operations engineers face when planning for construction and maintenance activities. There is a wide variety of approaches and methods that address work zone impacts, starting with simple equations, over spreadsheets... Most roads in the City of Madison, South Dakota were built more than 30 years ago, with chip seal as the primary maintenance practice. However, such treatments only provide temporary solutions to the surface and do not improve the structural deficiencies. To prevent accelerated pavement deterioration... Hyperspectral remote sensing is an emerging field with many potential applications in the observation, management, and maintenance of the global transportation infrastructure. This report describes the development of an affordable framework to capture hyperspectral images and models to classify the images.... National Bridge Inspection Standards do not require documenting damage location during an inspection but bridge evaluation provisions highlight the importance of location to determining the structural impact of damage. Capturing damage location information using current inspection and documentation methods... 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... To date, BIM (Building Information Modeling) is not widely utilized in infrastructure asset management. Benefits achieved through implementation in vertical construction, however, suggest that BIM represents significant opportunity for gains in process, material, and economic efficiency throughout infrastructure... |
