The Role and Benefit of Traffic Simulation in TSMO

AASHTO CTSO, ITE SimCAP Group, TRB Traffic Simulation Committee & Joint Simulation Subcommittee (SimSub) (ACP80)

Traffic simulation has steadily grown as a prominent practice in evaluating diverse and complex operational strategies. This includes many Transportation Systems Management and Operations (TSMO) applications (e.g., ramp metering, managed lanes, traffic signal prioritization, and integrated corridor management, among others). However, due to differing evolution and practitioner communities, TSMO personnel may not be fully aware nor are fully utilizing the capabilities of traffic simulation in their practice.

The intent of this webinar is to communicate the role and benefit of traffic simulation to TSMO practitioners. It will include an introductory presentation summarizing the capabilities of traffic simulation and its role in TSMO evaluation and decision-making. This is followed by several success stories utilizing traffic simulation in real-world TSMO deployments, including: (1) evaluating a predictive algorithm for a variable speed limit system in Virginia before implementation and (2) evaluating various TSMO strategies (dynamic lane and speed control, ramp metering, and hard shoulder running) along I-380 in Iowa. It concludes with an expert panel discussing how TSMO and modeling communities can bridge current gaps and collaboratively support TSMO deployment.

This webinar is envisioned to be the initial in a series of webinars showcasing traffic simulation success stories in TSMO deployments.

Target Audience

  • Wide-range of TSMO practitioners: senior managers with TSMO responsibilities, managers of specific TSMO strategies, and other TSMO operations staff.

  • Transportation engineering staff responsible for evaluation of operational strategies.

  • Modelers of traffic simulation.

Learning Objectives

  • Understand the role of traffic simulation in evaluating TSMO strategies and assisting TSMO decision-making processes.

  • Highlight success stories utilizing traffic simulation in real-world TSMO deployments (and the unique benefits traffic simulation provided).

  • Describe how TSMO and modeling communities can collaborate to support TSMO.

The NOCoE is intended to serve the emerging transportation systems management and operations (TSM&O) community, which is focused on deploying strategies and technologies to increase the safety and efficiency of the nation’s transportation system. Brad holds professional memberships with ITS Tennessee, ITS America and the Institute of Transportation Engineers. He is a past President of ITS Tennessee and currently serves on its Board of Directors. Brad currently lives in Millersville, Tennessee, with his wife, Rachel, 11-year-old daughter, Eliza, and his 8-year old daughter, Emajean.

Chris Melson (Louisiana State University): Chris Melson is the Program Manager of the Louisiana Local Technical Assistance Program. He previously worked for the Federal Highway Administration at the Turner-Fairbank Highway Research Center, where he developed and managed their traffic analysis, modeling, and simulation research program area. Chris currently serves as Co-Chair of the TRB Joint Simulation Subcommittee (SimSub), Co-Chair of the ITE SimCap Committee, and Chair of SimCap Louisiana.

Joe Blasi (HNTB): Joe Blasi has over 17 years of experience as a transportation planning engineer and project manager for the Kansas City office of HNTB. Mr. Blasi founded and leads the firmwide transportation planning modelers user group, which connects over 100 HNTB modelers to share modeling knowledge and experience. He was honored to be named an HNTB Associate Fellow in 2019 for his leadership of the modeling group and expertise in traffic modeling. He has three children and likes to play ultimate frisbee.
