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. The objectives of the proposed research are to: (1) develop a generic, conceptual framework for modelling heavy vehicle traffic and loading characteristics; (2) develop pragmatic models for integrating existing datasets to facilitate analysis and create new knowledge about heavy vehicle traffic and loading; and (3) analyze heavy vehicle activity to establish indicators needed for the design of highway infrastructure and the assessment of its performance. The applicant proposes to achieve these objectives by using the transportation systems analysis approach as the basis for model development, validation, and application. Ultimately, the research aims to improve the long-term performance of highway infrastructure in Canada by clarifying issues that should be considered in the design of highway infrastructure, informing better decision-making through the creation of integrated datasets, and adding to the pool of highly qualified personnel addressing these issues in the future.

拟议的研究计划开发了一个有关重型车辆交通和装载的新的全面知识基础，以支持基于绩效的高速公路基础设施设计。这项研究的动力源于人行道和桥梁设计的实践最先进的进步，这越来越需要对重型车辆活动的详细表征。 此外，鉴于运输基础设施不足的庞大而不断增长，土木工程师迫切需要采取新的实践来改善基础设施设计及其绩效评估。 尽管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数据集集成到系统框架中，以便能够开发足够详细且可靠的这项活动指标。这些指标是基于性能设计所需的输入。拟议的研究计划解决了这一知识差距。 拟议研究的目标是：（1）开发一个通用的，概念的框架，用于建模重型车辆交通和装载特性； （2）开发务实的模型，用于集成现有数据集，以促进分析并创建有关重型车辆交通和装载的新知识； （3）分析重型车辆活动以建立设计高速公路基础设施及其性能评估所需的指标。 申请人建议通过使用运输系统分析方法作为模型开发，验证和应用的基础来实现这些目标。 最终，该研究旨在通过阐明在高速公路基础架构设计中应考虑的问题，通过创建集成数据集的创建来为更好的决策提供信息，并添加到未来解决这些问题的高素质人员解决这些问题。
