RSG Principal Ken Kaliski and Senior Analyst Ryan Haac both coauthored a peer-reviewed paper, titled “In the shadow of wind energy: Predicting community exposure and annoyance to wind turbine shadow flicker in the United States,” which was published in the Energy Research & Social Science journal. The paper is also the subject of a webinar on March 11, 2022, at 3:00 p.m. ET (12:00 p.m. PT). The webinar is free and open to the public.

Ken and Ryan worked with their paper's coauthors from Lawrence Berkeley National Laboratory and Vermont Environmental Research Associates, Inc. to model shadow flicker (SF) exposure. SF is the effect of sunlight passing through moving wind turbine blades, which can lead to annoyance among those exposed.

The team modeled shadow flicker exposure at nearly 35,000 US residences across 61 wind projects and surveyed 747 people. The results shed light on what contributed to perceived shadow flicker and annoyance. The team did not find a significant correlation between shadow flicker annoyance and exposure. Instead, the team's model identified a greater correlation with other factors among respondents. These included a person's level of education, age, perception of how wind turbines look, and annoyance at other human-caused sounds.

Research of this nature is increasingly important as the renewable energy market expands. By 2035, the installed capacity of wind energy in the United States will be 600 gigawatts (GW), up from 110 GW now. This will require thousands of new wind projects. To understand how those projects will affect nearby communities, additional research like that undertaken by RSGers for this paper will be necessary to better understand wind turbine shadow flicker exposure.

RSG is sponsoring a webinar on Wednesday, January 26 from 1:00 p.m. to 2:00 p.m. ET to discuss key findings from our COVID-19 Transportation Insights Survey and similar research conducted throughout the pandemic. RSG will moderate the webinar. It will include several industry experts, academics, and researchers who will present on COVID-19 travel behavior changes. The webinar is free and open to the public.

The Institute of Transportation Studies (ITS) at the University of California, Berkeley named RSG Principal Johanna Zmud, PhD, as an ITS Senior Fellow for 2022. Johanna is one of only five Senior Fellows selected this year. The award recognizes her extraordinary contributions and dedication to the transportation field.

As a Principal at RSG, Johanna supports clients' needs around transportation technology and emerging mobility. She has cofounded several firms and worked in both the public and private sectors on travel behavior and transportation research.

As an ITS Senior Fellow, Johanna will continue her important work at RSG while shaping the industry conversation. Senior Fellows can collaborate with ITS faculty, staff, and students to improve transportation education, research, and practice.

Jim Brogan, PMP, joins RSG as a Vice President and brings over 25 years of experience in multimodal planning, operations, strategic planning, transit planning, and investment support at the national, state, and local levels.

Jim has helped state DOTs, MPOs, ports, railroads, transit agencies, and regional coalitions across the country more effectively identify and address multimodal issues within their planning and investment activities.

Jim's strategic mindset and emphasis on improving outcomes will empower RSG to continue to deliver unparalleled transportation and mobility insights to clients in both new and established markets.

We're excited to safely gather at the 2022 Transportation Research Board (TRB) Annual Meeting this month.

Many of the workshops and sessions this year will focus on the equity, resiliency, sustainability, and safety of the transportation system. RSGers are presenting individual posters and lectures on several related topics, including big data, COVID-19 travel changes, airport choice modeling, rail demand, and traffic noise modeling.

RSG is proud to be a Bronze Patron of the 101st TRB Annual Meeting, which attracts thousands of transportation professionals. Its sessions cover all transportation modes and inspire thought-provoking industry dialogue and change.

RSGers attending the Annual Meeting are following TRB's COVID Health and Safety Procedures, outlined here. A complete Annual Meeting program is available on TRB's website.

Kyeongsu Kim, PhD, joins RSG as a Director and brings over 15 years of experience in travel demand modeling and data analytics. Kyeongsu has led numerous innovative data analytics and modeling projects and has a proven track record that exceeds client expectations. Importantly, his analytical and project management skills will allow us to continue to bridge the project delivery gap between consultants and government agencies.

Jonelle Hanson, AICP, joins RSG as a Director and brings over 12 years of transportation planning experience in the public and private sectors. Her primary interests are in strategic mobility planning and long-range transportation planning. She is also researching the manufacturing of landing infrastructure for delivery using drones, or Unmanned Aircraft Systems (UAS). Jonelle's experience and expertise will allow us to continue to help clients plan for and adapt to rapidly changing traveler behavior.

The Zephyr Foundation has awarded PopulationSim its “Zephyr Software Badge” after RSG Senior Director Joel Freedman nominated the program. The award was made after Zephyr's Software Badging process found that the population synthesis program is easy to use, useful to Zephyr's community of users, and contributed to a common problem space.

RSG originally developed the population synthesis program for the Oregon Department of Transportation and its partner agencies. It replaced multiple population synthesis tools being used throughout the state at the time. Unlike other population synthesis software products, PopulationSim handles multiple geographies and avoids algorithmic errors. Moreover, RSG built it using software engineering best practices. This reduces the likelihood of bugs and enhances its utility to users. RSG included PopulationSim in the Python-based ActivitySim modeling framework, which we also led the development of.

RSG Director Michelle Lee coauthored a peer-reviewed paper, titled “The 2019 Conference on Health and Active Transportation: Research Needs and Opportunities,” which was published in the International Journal of Environmental Research and Public Health. The paper discusses expert conclusions from the December 2019 Conference on Health and Active Transportation (CHAT).

Active transportation, which includes activities like bicycling and walking, has well-known public health benefits. These modes, when replacing personal vehicle trips, can also reduce emissions. The COVID-19 pandemic revealed new opportunities for active transportation. At the same time, the pandemic highlighted societal inequities around transportation access and health.

Michelle and her fellow authors present a conceptual model, based on CHAT sessions, that could assist practitioners in overcoming barriers to the development and use of active transportation infrastructure. The paper also identifies crucial research gaps. Importantly, the paper emphasizes the importance of coupling additional research with plans for dissemination and implementation.
