A National Dataset to Model the Impact of Evolving Trends on Transportation System Performance

Tuesday, June 10, 2025
4:45 PM – 6:00 PM MT
Abstract: In science, in general, and in the transportation sciences, specifically, data plays a foundational role in our ability to set aside incorrect intuitions and bank on data-driven informed decisions to move forward. However, in addition to the ever-changing nature of life and human behavior, the significant technological advances in the past few decades have led to the rise of novel trends that have been further changing and shaping our travel behaviors and likely affecting the performance of our transportation systems in different ways. Accordingly, having a dataset that can help us understand the impacts of the various existing traditional and evolving trends on the transportation system performance is imperative for our ability to make informed decisions and develop effective policies. In this paper, the authors present their work on developing a national dataset to model the impacts of the different traditional and evolving trends on the performance of transportation systems. The developed dataset was created for county-level measures spanning most years between 2001 and 2019. The authors’ work was developed in several steps: 1) identifying the various existing traditional and evolving trends affecting our transportation system performance, 2) identifying different quantitative indicators that can be used to capture each of the identified trends, 3) investigating the suitability of different publicly available data sources for estimating the identified quantitative indicators, 4) analyzing the strengths and limitations of the different identified indicators and the data sources utilized to compute them, 4) selection of the final list of indicators for the different trends, 5) development of the (Python) code for the computation of the indicators, and 6) creation of the dataset. This paper also discusses and presents the evolution of the computed indicators and their trends over time. The developed dataset should be highly valuable for the research and practice communities, as well as any agency interested in investigating the evolution of the different computed trends and their impacts on our transportation systems.

Learning Objectives:

Attendees can expect to learn the following from this session:
  • List the main traditional and evolving trends affecting transportation systems performance
  • Discuss the strengths and weaknesses of many different publicly available transportation data sources
  • Explain the value of the developed dataset for understanding and modeling the impact of the evolving trends on transportation system performance
