This presentation was given by Jerauld Oxsen at the 11th National Conference on Transportation Asset Management. The main focus of this presentation is to outline the challenge of data collection during turnover periods and presents a possible way to handle it. The presentation uses the Bay Area Rapid Transit Silicon Valley Extension (SVBX) as its example.

Prepared by Kartik Manda of Applied Pavement Technology, this presentation was part of the "How to Manage Your Assets" session of the 11th National Conference on Transportation Asset Management. Mr. Manda's primary focus was to develop a set of guidelines for data collection and processing. These guidelines include 4 steps– preparing for methodology selection, methodology selection, collecting the data, and data processing and management.

This presentation regarding transportation data management and integration was given at the 11th National Conference on Transportation Asset Management. It primarily concerns the WYDOT effort to increase use of data driven decision making to win HSIP funding in order to increase safety and reduce the number of critical crashes per year per district.

This presentation focuses on pavement management and maintenance prioritization at the Seattle Department of Transportation (SDOT). This includes all aspects from data collection to methods for budgeting evaluation (e.g. benefit/cost ratios). It also outlines the next steps for SDOT including adding traffic volume to analysis techniques.

This presentation explains the Metropolitan Transportation Commission's (MTC) effort to improve its pavement management system. It seeks to first improve its data quality and consistency through a Data Quality Management Plan that will provide pavement engineers with adequate training and skills to more thoroughly analyze pavement conditions. It outlines the process for the certification of these engineers.

This presentation is a summary of the Interstate Condition Project overseen by Amec, Foster, Wheeler. It begins by giving background on MAP-21 and the Interstate Condition Project. It then analyzes the collected data using a variety of methods. Finally, it summarizes the findings, weighing their merit and what information it accurately portrays.

This presentation analyzes the effect of climate change on pavement life cycle costs. It begins with an overview of our changing climate–the motivation for this study–and then transitions into the methods used for the study. The study used a number of programs and data collection methods to aid in its predictions. As a result, it found that climate change accelerates deterioration and will increase life-cycle costs.

This presentation discusses the Michigan DOT's effort to integrate climate risk into their transportation asset management plan. It begins by identifying assets at risk as well as climate variables such as temperature, and precipitation. It then uses this information for a statewide risk analysis on bridges and roadways, noting particularly at-risk areas such as Trunkline, Pump, and Culvert.

This presentation focuses on bridge data analysis in the state of California. It uses National Bridge Inventory (NBI) data to analyze the strength and serviceability of California bridges while also analyzing the correlation between location, material, traffic volume, and age. It concludes with general trends found in research and a review of difficulties with use of the program.

This presentation focuses on the National Bridge Investment Analysis System (NBIAS) and its uses for transportation agencies. It first gives background on the NBIAS software, followed by an explanation of how it analyses bridges to evaluate risk. The software analyzes safety, infrastructure condition, congestion and reliability, economic vitality, and environmental sustainability and identifies an annual investment plan.

This presentation focuses on improving understanding of bridge deterioration and maintenance. It begins by defining three types of deterioration– native deterioration, post-rehabilitation deterioration, and impact of preservation on deterioration– and strategies for condition predictions. It continues to explain how risk incorporation can further aid decision making and funding allocation.

This presentation focuses on bridge management in the 21st century. It beings with a case study of the Auckland Harbor Bridge in New Zealand. It identifies the issues with the bridge and recommends a robust maintenance strategy that takes into account the budgetary limitations of the 21st century. It then expands on these strategies to encompass bridge programs more generally.
