This presentation focuses on asset vulnerability in the wake of floods. The presentation examines the vulnerability assessment scoring tool (VAST) based off of the Post Event Assessment of Resilience (PEAR) developed by the US DOT to determine which asset are at risk due to climate vulnerabilities. Using this tool DOTs are able to estimate their exposure and sensitivity, however the system can still be improved.

This presentation outlines the possible effects climate change could have on transportation asset management. It begins with an overview of climate change, and then transitions into the discussion of deteriorating infrastructure and the contribution of environmental stressors to that deterioration and as a result the changes in life-cycle cost analysis and cost comparisons.

This presentation focuses on the use of sensor and scanning technologies for data collection at the Massachusetts Department of Transportation (MassDOT). MassDOT uses thermal scanning, scanning cleaning systems, bus washing sensors, and LiDAR to improve efficiency and save on costs within its system. This presentation outlines the uses of those systems and explains both the pros and cons accompanying each one.

This presentation focuses on data collection methods in the city of Manchester, New Hampshire. It begins by introducing the city and the challenges it currently faces and then transitions into discussion about the city's pavement and asset data collection approach. Manchester recently implemented an enterprise asset management system, eventually collecting data on all city owned and maintained streets. This resulted in an drastic increase in asset management efficiency.

This presentation focuses on data collection and management. It uses 2 case studies to examine different data collection methods and productivity. It begins with data collection on guardrails at MassDOT and the difficulties accompanied by it. The second case study discusses remote data collection at the Michigan Department of Transportation.The conclusions from both studies indicate that data is most supportive when it can be discussed face to face between departments.

This presentation focuses on asset condition for ancillary traffic structures. It applies current condition basis to existing structures and uses Design Criteria in the risk assessment for the design of new structures. It explains this information through a case study of asset risk in Delaware versus the District of Columbia.

This presentation outlines asset management and the upcoming MAP-21 requirements. It then explores risk analysis, matrices, and probability of failure, including examples. It concludes by showing the use of risk assessment for budget forecasting for life-cycle planning using scenario simulation programs.

This presentation focuses on the management of geotechnical transportation assets including retaining walls, slopes, embankments, and subgrades. It outlines the MAP-21/FAST requirements for these types of assets and the biggest risks posed to them and their consequences. It concludes with a risk cube visualization exercise to understand a method for multi-objective risk management and evaluation.

This presentation gives an overview of life-cycle planning in asset management. It begins by giving background on Beijing's transportation assets and the bridge, railway, and pavement management systems it employs for life-cycle cost analysis of assets. It then explains the current asset management system. It concludes with the key issues that the Beijing Transportation Department is currently facing, including a sustainable asset management system, communication, and an effective data management system.

This presentation begins by defining the elements of risk and then risk itself. It explains the process used to quantify risk and the probability of failure. It concludes by explaining the application of this quantity in asset management and set goals for the future of risk based asset management techniques.

This presentation outlines the CPCS process for life-cycle value assessments. The process is explained through a case study of the Delhi International Airport Limited project. It includes Monte Carlo simulations, demand projections, and future flexibility. It concludes that flexibility in technical design and and contracts could have positive effects for value at-risk and value shares.

The presentation beings by defining asset management, life-cycle cost assessments, and risk based asset management requirements. It then works through case studies of Colorado road rehabilitation, Oregon seismic risks, and Alaskan climate change among others. It concludes by identifying the overall lessons learned.
