Traffic Simulation Through the Decades

This webinar is led by the ITE Simulation and Capacity Analysis (SimCap) Committee.

Webinar Description:
This webinar shows the evolution of traffic simulation by highlighting key, progressive advancements to the field: (1) from developing the first FHWA-produced traffic simulation models in the 1970s and 1980s, (2) to modeling improvements spurred by the Next Generation Simulation (NGSIM) effort in the 2000s, and (3) to current trajectory-level research, datasets, and products.

  • Presentation #1 - Traffic SImulation in the 1970s and 1980s
This presentation will identify the computing challenges of the 1970s and 1980s and describe how they shaped the development of early traffic simulation models. FHWA’s vision to address these challenges will be described along with the variety of models that were created as a result. The major contributors and visionaries of the era will also be identified along with their contributions.
  • Presentation #2 - Traffic Simulation in the 2000s
This presentation provides a retrospective of FHWA's Next Generation Simulation (NGSIM) effort. It provides an overview of the NGSIM project, the trajectory-level data collected, its influence on FHWA's role in traffic simulation, and its long-standing impacts to current models in practice and research.
  • Presentation #3 - Current Initiatives, Recent FHWA-sponsored TAMS Research - Trajectory-Level Data
This presentation will highlight some of the recent vehicle trajectory data collection efforts funded by the Federal Highway Administration. The importance of trajectory level data, data elements in each dataset, data use cases, and how to access the datasets as they become available will be discussed. Samples of data that were collected as part of these efforts will also be shown.

Learning Objectives:
Presentation #1 - Traffic Simulation in the 1970s and 1980s:
  • Understand the key computing challenges to developing and applying simulation models during this period
  • Recall FHWA’s vision to address these challenges
  • Discuss the variety of models that were developed from this vision
  • Appreciate how that era was both similar and different from today
  • Recognize the major contributors to simulation development at FHWA, academia and private industry
Presentation #2 - Traffic Simulation in the 2000s
  • Describe the scope and data collected as part of the FHWA's Next Generation Simulation (NGSIM) effort.
  • Explain how the NGSIM effort changed FHWA's role in simulation.
  • Describe how the NGSIM data influenced current simulation models and algorithms.
Presentation #3 - Current Initiatives, Recent FHWA-sponsored TAMS Research - Trajectory-Level Data
  • Understand why trajectory-level data is important for microsimulation models.
  • Explain how trajectory-level data can be used in traffic analysis.
  • Understand how individuals can access FHWA’s trajectory-level datasets for free.
