46 ApproAch Based on the analysis of the survey responses, several intriguing uses of pavement management data were identified and believed to warrant further examination. Each of these uses is featured as a case example to provide the opportunity to explore the reasons for their application and how they were implemented.

50 provides the information needed to identify locations where some type of countermeasure could be used to address a high-risk location. There were several challenges associated with performing these types of analysis, including the following: • The precision and availability of crash reports can be somewhat dependent on the police officer at the crash scene.

51 One of the challenges that the agency faced in conducting the analysis was the difficulty in separating the pavement-related costs from other costs on projects where multiple issues were being addressed at the same time. This is primarily because contract cost data stored in financial cost tracking systems are typically developed for contract administration rather than post-contract evaluation.
