Overall Program Presentation 2


PowerPoint Version (3,032 kb)


Diagram. LTBP Program Objective. The diagram depicts an arrow starting thin at the left bottom part of the diagram and widening towards the top-right. There are three circles near the tail, middle, and head of the arrow proportion to the arrow width. The text below the first (smallest) circle near the tail states the first LTBP program objective as Collect, document and maintain high quality, quantitative performance data. The text below the middle circle near the middle of the arrow states the second LTBP program objective as Improved knowledge of bridge performance. The text below the last (largest) circle near the arrow head states the third LTBP program objective as Improved asset management.


Program Objectives



Program Objectives



Organization Chart. LTBP Team. The chart depicts the organization of the LTBP program team. The organization of LTBP program starts by a box in the top with the FHWA program manager in TFHRC. The second box of the management team comes below the FHWA box and includes two boxes inside representing Rutgers University and PB. A small box to the right is connected with a line to Rutgers University box and includes TFHRC labs. The second level of the team includes four boxes below the management team. These boxes from left to right represent Utah State University, Virginia Transportation Research Center, Siemens America, and Institute of Transportation Studies UC Berkeley. The third level comes below the second level and includes two boxes which are from left to right: Bridge Diagnostic Inc., and Advitam.


Diagram. Vision and Fundamental Considerations. The diagram shows a blue oval in the center top of the diagram with a white text stating Vision and Fundamental Considerations. Three arrows pointing from the oval down to the left, center, and right to three blue boxes with white text. The texts in the left, center, and right boxes state Understanding Performance, System Approach, and Toward Effective Asset Management, respectively.


Diagram. Understanding and Evaluating Performance. The diagram shows two light blue thick arrows (one in the upper left quarter of the diagram, and the other in the bottom right quarter) and a thick light blue line in the center level inclined down in the left and up in the right. The arrow in the upper left quarter is pointing downwards to a text under the line stating Understanding performance is key to address bridge deficiencies and the design/construction of superior bridges of the future. The arrow in the bottom right quarter is pointing upwards to a text over the line stating Performance is a critical factor in optimal operation of highway systems.


Understanding and Evaluating Performance


Understanding and Evaluating Performance


Diagram. Goals and performance categories. Structural Condition and Integrity, Safety of User, and Cost to User and Agency. The diagram depicts three main performance categories. Three separate orange boxes arranged top-down with white text in each box stating Structural Condition and Integrity in the top box, Safety of User in the middle box, and Cost to User and Agency in the lower box. Three bigger light green boxes to the right of the three orange boxes with outlined black text explaining the text in the left orange boxes
Diagram. Highway Transportation as a Multi-Domain, Multi-Disciplinary, Layered System-of-Systems. The diagram shows three groups of boxes in the left, center and right of the diagram. The left part has text in the top stating Inputs and Constraints over four vertical rectangles with text in each rectangle from left to right stating: Politics, Policy, Planning, Revenue Mechanisms, Financing Mechanisms, Quality of Education and Training. The middle part has three rectangles with text in each rectangle from top to bottom stating: Human, Engineered, Nature. The right part has text in the top stating  Desired Outcomes over five vertical rectangles with text in each rectangle from left to right stating: Operational Efficiency/Reduced Congestion, Operational Safety and Security, Serviceability, Safety and Preservation of Assets, Environmental Stewardship, and Organizational Excellence.

Diagram. Program Approach. The diagram shows six small circles formed in a circular path. The text in the six circles states: Improved Knowledge of Bridge Performance and Better Asset Management, Life Cycle Cost Analysis, Deterioration Models, Performance Measures, Data Collection and Data Management, Pilot Program: Initial Field Work / Sampling, and Program Initiation and Pilot Planning.
Matrix Diagram. Development and Pilot Phase Tasks. The diagram depicts a spreadsheet matrix with two columns to the left for the task number and task description followed by eight columns with headings for the LTBP program team members who are from left to right: CAIT, PB, UTC, VTRC, Siemens, Advitam, BDI, Emin Aktan. The matrix has eleven rows in addition to the upper heading row. The task numbers and descriptions in the first two columns from top to bottom are: 1.1 Road Map, 1.2 Specific data to be collected, 1.3 Development of Data Infrastructure, 1.4 Protocols for data sampling, collecting and Q/A, 1.5 Bridge Sampling Methodology, 1.6 Synthesis of bridge monitoring and autopsy methods, 1.7 Protocols for Bridge Monitoring and autopsy, 1.8 Communication/Marketing Plan and Products, 2.1 Project Coordination (for fieldwork), 2.2.1 Draft Pilot Study Plan, and 2.2.2 Pilot Study Execution. The cells (blocks) in the matrix are colored by orange or yellow or left blank. The yellow cell has a ? mark and indicates that team member will provide significant contribution to the task. The orange cell has an X mark and indicates team member with primary responsibility.
