Abstract:

The objective of this research was to develop a unified format and nationally compatible In-Service Performance Evaluation (ISPE) methodology employing various individual state database parameters. The ISPE methodology developed under this research capitalizes on data that are often already available in a typical Transportation Agency and minimizes new data collection to situations where it is beneficial. This report summarizes the research effort. Phase I consists of eleven research tasks, including an alpha test of the research products—NCHRP Research Report 1010: In-Service Performance Evaluation: Guidelines for the Assembly and Analysis of Data (Carrigan and Ray 2022) (hereafter referred to as the “ISPE Guidelines Document”), the ISPE Resource Hub, and the ISPE Data Set and Analysis Template. The research team and panel members participated in an alpha test of these products, which led to the verification and validation of the Phase I research products. These early research products evolved into beta versions. Training materials for the conduct of ISPEs using this methodology were developed and presented in a two-day workshop to ten Transportation Agencies. Following the workshop, these Transportation Agencies conducted a pilot test of the research products. The comments received during the pilot test have been incorporated into the research products. The results presented in this report are the culmination of all the research tasks rather than a rendition of each of the steps taken in pursuit of the research objectives. The pilot test resulted in nine ISPEs being successfully executed and documented. An example of an ISPE report developed during the pilot test is available in Appendix A. Additionally, a standalone technical memorandum titled “Implementation of Research Findings and Products” and a PowerPoint file summarizing the research have been developed and submitted along with this Final Report.
