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、全面的知识库，以支持公路基础设施的基于性能的设计。研究的动力来自于路面和桥梁设计实践的进步，这越来越需要详细描述重型车辆的活动。 此外，鉴于运输基础设施赤字巨大且不断增加，土木工程师迫切需要采用新的做法，以改进基础设施设计及其性能评估。 虽然有各种数据来源可用于描述重型车辆活动的特征，但在如何将这些不同的数据集整合到一个系统框架内，以便能够制定足够详细和可靠的重型车辆活动指标方面，仍然存在重大的知识差距。这些指标是基于性能的设计所需的输入。本文提出的研究计划旨在填补这一知识空白，其目标是：（1）建立一个通用的、概念性的框架来模拟重型车辆的交通和负载特性;（2）建立实用的模型来整合现有的数据集，以便于分析和创造有关重型车辆交通和负载的新知识;（3）分析重型车辆的活动情况，以建立公路基础设施设计和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，该研究旨在通过澄清公路基础设施设计中应考虑的问题，通过创建综合数据集来更好地决策，并增加高素质人才库来改善加拿大公路基础设施的长期绩效。
