Under the study, "Improving FHWA's Ability to Assess Highway Infrastructure Health," FHWA sought to identify a means for assessing the health of the Interstate Highway System with a focus on pavements and bridges. In particular, the pilot study, Interstate 90 through South Dakota, Minnesota, and Wisconsin, evaluated methods to identify and validate approaches for categorizing bridge and pavement condition as good / fair / poor. The pilot study demonstrated that the good / fair / poor approach is not only feasible for pavements, but also implementable at this time using pavement roughness. Additionally, the use of the Highway Performance Monitoring System (HPMS) distresses was shown to be feasible, but additional work is required before they can be implemented. Accordingly, a continuation of the good / fair / poor development effort focused on pavement condition indicators including the HPMS distresses. The objective of the effort performed under the continuation was to develop a next generation pavement performance measure, which will enable the FHWA to more accurately and consistently assess the functional condition of portions of, or the entire, national highway pavement system. Based on project parameters, the measure was to consider ride quality and pavement surface distresses (cracking and rutting or faulting). In subsequent review of this objective, it was determined that reviewing condition in terms of each individual distress provided more reliable information than an index combining these data. In an effort to improve how these data would be used to assess condition, the following data elements were considered with regard to use of these data: ≤ Data collection ≤ Data processing ≤ Data quality control / quality assurance ≤ Data storage ≤ Condition rating Within this paper, we will explore these elements as they relate to ride quality.
