Evaluation of Highway Performance Measures for a Multi-Study Corridor - A Pilot Study
1.0 Data Aquisition and Analysis Plan
The goal of the project was to integrate pavement and bridge performance data from a multi-state corridor to facilitate analysis of performance measures, and to evaluate how performance data can be used for corridor management.
The project consisted of the following four tasks:
- Task 1 - Data Acquisition and Analysis Plan;
- Task 2 - Data Collection and Integration;
- Task 3 - Analysis and Evaluation of Alternative Condition Indicators; and
- Task 4 - Develop Condition Indicator Display Capability.
The results of each task are detailed in this report.
1.2 Report Organization
The remainder of this report is organized as follows:
- Section 2 summarizes the results of the data acquisition and analysis task. It presents the plan for acquiring pavement and bridge data and the scope of the data collection effort.
- Section 3 summarizes the results of the data collection and integration task.
- Section 4 summarizes the results of the analysis and evaluation of alternative condition indicators task. It recommends how cross-state asset data should be analyzed to support decision-making and discusses the degree to which cross-state comparisons can be made based on the sample data collected through Task 2.
- Section 5 documents the design report for adding condition indicators to the Integrated Corridor Analysis Tool (ICAT) developed by the I-95 Corridor Coalition and lists any other ICAT changes to support this enhancement.
