T-SCORE Presentation with Don MacKenzie

Dr. Don MacKenzie of the University of Washington will be visiting Georgia Tech to speak about the interaction between transit and ridehailing. Ridehailing services may serve as a substitute or a complement—or some combination thereof—to transit. Automation is expected to further complicate the current complex relationship between these two modes. One significant area of interaction is in travel demand. Professor MacKenzie will share a study of how US commuters’ stated willingness to ride transit is influenced by the price of ridehailing services and whether the service is provided by an autonomous vehicle. Results indicate that ridehailing per se might not be a significant competitor to transit, especially if it is integrated as a first-/last-mile service. However, if ridehailing prices are significantly reduced by automation, the result could be a decline in total transit ridership and an increase in ridehailing, especially for solo ridehailing. Another area of interaction is in operations. Professor MacKenzie will introduce an ongoing project aiming to measure bus delay and interference caused by ridehailing, goods delivery, and other road users. As part of this effort, his team is developing TransitVis, a set of tools for scraping, aggregating, and visualizing transit speed and reliability citywide using GTFS-Realtime data.

TRB 100th Annual Meeting – Lectern Session 1197

Dr. Kari Watkins spoke at a session on Planning for Transit in a Post-Pandemic Future. The COVID-19 pandemic has had a tremendous impact on the public transportation industry, affecting everything from operations to ridership to financial stability. Although the industry has shown substantial resilience in responding to the pandemic in the short-term, the longer-term effects must also be considered. This session will consider the longer-term effects on the transit industry and how agencies are planning for the uncertain future.

TRB 100th Annual Meeting – Lectern Session 1125

Dr. Greg Erhardt spoke as part of the lecture event entitled “Do Revealed Preferences Tell us Much about our Travel Needs?” on January 25, 2021. Transportation planners use analytical analyses of system “deficiencies” to identify, prioritize, and design transportation investments. Existing and potential future deficiencies are measured by estimating improvements in user time and cost with travel demand models.

2020 Georgia Transit Association Conference

Dr. Kari Watkins gave a presention on Monday, November 16th from 3-3:45 on The New T-SCORE University Transportation Center. Attendees will learn about a new US DOT-funded University Transportation Center led by Georgia Tech (T-SCORE). Transit ridership in the U.S. had declined for five straight years, even prior to the COVID-19 pandemic. To turn the declining ridership trend around, transit agencies have been trying many new strategies and searching for more. Over the next 18 months, T-SCORE will define a set of strategic visions to help guide public transit into a sustainable and resilient future, and to equip local planners with the tools needed to translate their chosen vision into their own community.

MAXimum Impact Webinar Series

Dr. Kari Watkins participated in an interactive webinar entitled “Predicting the Unpredictable: What Might Mass Tranist After COVID-19 Look Like”.The challenges facing public transit due to the COVID-19 pandemic are complex and multifaceted. Transit agencies are having to make difficult decisions with dozens of competing forces. Can they balance meeting social distancing requirements without running numerous empty buses or trains? Can they effectively plan for next year despite steep declines in sales tax revenues and diminished capital operating budgets? In this interactive webinar, we’ll discuss and workshop ideas on how transit leaders can manage change during this uncertain time and prepare for what’s coming next.

TRANScend: Critical Conversations for the Year Ahead

Dr. Kari Watkins, T-SCORE Director, spoke as part of the event “What Megatrend Should we be Paying Most Attention to Right Now?” Over the last decade the technology megatrends of smartphone adoption and electrification had tremendous impacts on urban mobility. So did the demographic megatrend of affluent people increasingly choosing to live in urban areas. What will the next decade bring? Looking ahead, possible technology megatrends include automation, artificial intelligence, and enhanced connectivity through 5G. On the societal side, possibilities include a retreat from density or a preference for sharing assets instead of owning them. Overlayed on top are the overarching forces of climate change and political polarization. Which of these is most likely to define the coming decade? What impact will they have on transit? Are there steps agencies should take now to prepare?

49th Annual ORSSA Conference

Dr. Pascal Van Hentenryck delivered the Closing Keynote Address, “Future mobility systems.” The sharing economy has radically transformed taxi services in the last decade, through the combination of new business models and advanced technology. However, most of the mobility needs are not addressed by these innovations. This talk will review how ICT technology and Operations Research have the potential to revolutionize public transit and commuting in general. The presentation will introduce the new mobility services addressing these needs, the OR techniques that powers them, real case studies, and the barriers that remain for large-scale adoption.

TRB Webinar: How Accurate are Traffic Forecasts?

Dr. Greg Erhardt and Jawad Hoque were presenters as part of a TRB Webinar “How Accurate are Traffic Forecasts?” Traffic forecasts play an important role in the planning and design of road projects, but we know little about how accurate they are. TRB will host a webinar on Wednesday, October 14, 2020 from 2:00-3:30 PM Eastern that will address these gaps, comparing forecasts and post-opening traffic counts for more than 1,200 road projects in the United States and Europe. Presenters will identify the factors in forecast accuracy. They will also demonstrate a method for estimating the uncertainty of future forecasts from data on the accuracy of past forecasts, and provide recommendations on how to improve traffic forecasting practice.This webinar draws on research from the National Cooperative Highway Research Program (NCHRP) Research Report 934: Traffic Forecasting Accuracy Assessment Research.
