RSG cofounder's watershed study validated using real-world data nearly 50 years later

RSG cofounder Dennis Meadows was part of a team of MIT researchers who released a groundbreaking environmental study in 1972. Now, new research conducted by KPMG Director Gaya Herrington and published in Yale Journal of Industrial Ecology has confirmed the findings of Meadows's team's study against current real-world data and trends.

The original report documenting Meadows's findings, titled The Limits to Growth, was based on system dynamics modeling of society's resource use and extraction. In it, Meadows's team looked at then-current trends to predict several future scenarios. Importantly, one of these scenarios was a base case the would result in a decline in both industrial and population capacity. The latest research from KPMG confirms the accuracy of Meadows's team's modeling based on current trends.

Counting Our Communities: Considering LGBTQ+ Identities in Travel Behavior Data Collection & Modeling (Webinar)

RSG is leading an industry-first webinar on Tuesday, August 10 from 2:00 p.m. to 3:00 p.m. ET to discuss the value and practicalities of collecting data on LGBTQ+ populations as part of travel behavior data collection and modeling. It will be moderated by RSG and comprises a diverse panel of travel behavior experts, community organizers, and academics. The webinar is free and open to the public. Click here to register.

About the Webinar

According to Gallup, at least 5.6% of all Americans identify as LGBT. Despite the growing political and social visibility of LGBTQ+ communities, the US Census Bureau does not collect data on individuals’ sexual orientation and gender identity (SOGI). Moreover, most state departments of transportation and metropolitan planning organizations do not collect similar information as part of routine surveys. The lack of inclusion in most surveys to date has resulted in a persistent underrepresentation of LGBTQ+ populations that often impedes the evaluation of inequities or differences in travel behaviors through an intersectional equity lens.

This moderated panel conversation will discuss research on travel behavior among LGBTQ+ populations. It will also describe current travel behavior survey and modeling practices for historically underserved populations as a whole and offer agency perspectives on surveying LGBTQ+ populations as part of regional travel surveys. Attendees will hear from several industry experts and come away with insights into the benefits and challenges of collecting SOGI data in the context of transportation planning.

RSG ridership tool supports $117 billion, 15-year plan for Northeast Corridor

RSG created the ridership demand forecasting tool that supported the development of CONNECT NEC 2035 (C35), a recently released $117 billion blueprint to modernize and improve the Northeast Corridor (NEC). C35 details 150 projects to improve rail service in the NEC over the next 15 years. It has involved multiple agencies and has been overseen by the NEC Commission.

The ridership demand forecasts developed by RSG estimated commuter and intercity ridership using a customized elasticity-based ridership tool. This tool incorporated behaviors embedded in existing ridership models. It included demand sensitivities to travel time, service frequency, and fare prices. The tool's outputs helped C35's planners evaluate ridership changes and improvements that would include corridor-level changes in vehicle and passenger miles traveled, travel time savings, and mode shifts to rail (from auto, air, and bus).

The work proposed in C35, if fully funded and completed, would create 1.7 million new jobs and deliver service improvements. These improvements would include a 26-minute reduction in travel time between Washington, DC, and New York City; riders would also see a 28-minute reduction in travel time between New York City and Boston. Importantly, work will result in fewer delays, new direct and express services, and off-peak and reverse-peak trains.

Return to Transit? Surveying Chicago’s Current and Lapsed Transit Riders During the COVID-19 Pandemic

The pandemic drastically reduced transit ridership across the United States. In response, RSG worked with the Regional Transportation Authority (RTA) in Chicago on an innovative region-wide survey of current and lapsed transit riders. The findings have been used by RTA, its Service Boards (CTA, Metra, and Pace), and the Chicago Metropolitan Agency for Planning to better understand their shifting markets throughout the pandemic and to then guide future planning and policymaking as the pandemic recedes.

On Friday, June 18 at 10:00 a.m. ET, RSG Consultant Alexander Levin will present an overview of the current and lapsed rider survey methodology and explore the key findings from the study as part of a webinar hosted by Transport Chicago. Alexander's presentation will spotlight the following:

  1. Findings we previously saw anecdotally but now have local survey data to confirm (e.g., who relied on transit during the pandemic).
  2. Findings that tell us where transit use might be going in the Chicago region (e.g., the role of telework).
  3. Findings that tell us what transit agencies can do to encourage a return to transit (e.g., where riders want future investment targeted).

​Transport Chicago is an annual conference dedicated to the mission of improving transportation in the Chicago region and beyond. This year's conference is entirely virtual. It will also feature Donald Shoup as keynote speaker.

RSG's COVID-19 Transportation Insights Survey marks one year of data collection

RSG's COVID-19 Transportation Insights Survey recently marked one year of data collection since the start of the pandemic.

Since May 2020, our COVID-19 Transportation Insights Survey has collected data from more than 21,000 respondents across 7 survey waves. This nationally representative dataset is now one of the largest sources of longitudinal information on how the pandemic has changed travel in the United States.

The pandemic has raised a seemingly endless array of planning questions. Will telework replace in-office work? Does an effective and readily available vaccine prompt people to travel again? What modes will people favor after the pandemic? For the past year, our findings have helped clients answer these questions—and many more.

RSG plans to conduct at least three additional survey waves before the end of this year. These additional waves will help us chart the emerging contours of what the resumption of travel looks like once more people are vaccinated and COVID-19 restrictions are lifted.
