The proposed research program develops a new, comprehensive knowledge base about heavy vehicle traffic and loading to support performance-based design of highway infrastructure. The impetus for the research arises from advancements in the state-of-the-practice for the design of pavements and bridges, which increasingly requires detailed characterization of heavy vehicle activity. Moreover, given the large and growing transportation infrastructure deficit, there is an urgent need for civil engineers to adopt new practices to improve infrastructure design and the assessment of its performance. While there are a variety of data sources available to characterize heavy vehicle activity, there remains a significant knowledge gap concerning how these disparate datasets may be integrated within a systematic framework to enable development of sufficiently detailed and reliable indicators of this activity. These indicators are the inputs required for performance-based design. The proposed research program addresses this knowledge gap.

拟议的研究计划开发了一个关于重型车辆交通和装载的新的综合知识库，以支持基于性能的公路基础设施设计。这项研究的动力来自于路面和桥梁设计实践的进步，这越来越需要重型车辆活动的详细表征。此外，鉴于交通基础设施赤字巨大且不断增长，土木工程师迫切需要采用新的做法来改进基础设施设计及其性能评估。虽然有多种数据源可用于表征重型车辆活动，但关于如何将这些不同的数据集集成到系统框架内以开发足够详细和可靠的该活动指标，仍然存在很大的知识差距。这些指标是基于性能的设计所需的输入。拟议的研究计划解决了这一知识差距。
