RSG Director Dana Lodico, PE, INCE Bd. Cert. recently coauthored an article that was published in the latest issue of the Noise Control Engineering Journal. The article, titled “Acoustical longevity and durability of pavements,” examined findings from four long-term pavement studies to determine how quieter pavements held up over time when compared to their more rigid counterparts. The long-term studies reviewed by Dana and her coauthor looked at pavements in Arizona and California. Their paper concluded that quieter pavements, which experience some noise level increase over time due to wear, continued to offer noise reduction benefits years later when compared to some rigid pavements. This paper adds to a growing body of research that will help US regulatory agencies assess the feasibility and practicality of employing quieter pavement technologies as one method to help reduce overall vehicle noise levels from our nation's roadways.

We are thrilled to welcome Dana Lodico, PE, INCE Bd. Cert. as a Director at RSG. Dana brings 21 years of experience in acoustical consulting, civil engineering, and acoustical research. She is also Vice President of the Institute of Noise Control Engineering. Dana's experience and expertise will help us continue to identify creative solutions to acoustics problems.

Yesterday, during recorded testimony at the Vermont Senate Committee on Transportation, an employee of Resource Systems Group, Inc. (RSG) was overheard making an on-mic racial slur. In response to this, RSG CEO Stephen Lawe issued the following statement:

“On behalf of the entire company, I apologize to anyone affected by these deplorable remarks. The outburst by an employee of RSG is both regrettable and unforgivable. This kind of behavior is not at all tolerated and the employee was terminated immediately.

“RSG takes great pride in the quality of work and the quality of employees in our organization. We have immediately begun to put in place additional safeguards to assure that our current employees are aligned properly with our company values and uphold them – as well as assure that all future employees uphold those critical values.”

Activity-based models offer more functionality than standard trip-based models. However, user concerns about activity-based models’ cost, complexity, and support have limited their wider adoption.

ActivitySim is different. It is open source, purpose-built, and grounded in the principles of collaboration and modern software engineering.

ActivitySim was developed by RSG and is the product of a consortium of member agencies overseen by the Association of Metropolitan Planning Organizations (AMPO). Most importantly to users, it is a state-of-the-practice modeling platform that is always improving.

RSG President Tom Adler coauthored an article for the latest issue of TR News. The article summarizes research RSG conducted into how transportation network companies such as Uber and Lyft have impacted airport revenues and operations. Specifically, it discusses findings from ACRP Research Report 215: Transportation Network Companies (TNCs)—Impacts to Airport Revenues and Operations—Reference Guide, which was published in 2020.

ACRP Research Report 215 follows work done as part of ACRP Synthesis 84: Transportation Network Companies—Challenges and Opportunities for Airport Operators, which was published in 2017. ACRP Synthesis 84 concluded more research was needed into the topic. In response, ACRP Research Report 215 describes strategic approaches and practical tools that airports can reference to develop ground access programs that align with their policy goals. Both ACRP Research Report 215 and ACRP Synthesis 84 surveyed 100 of the largest airports in the United States. These findings helped the research team understand TNC operations at each of these airports, the resulting access mode shares, and the revenues received from TNC fees. The data also helped the research team develop integrated supply and demand models to estimate the effects of TNC growth and TNC-related pricing policies on airport access mode shares and revenues.

The application of the models confirmed the complex (and often counterintuitive) relationship between pricing, revenue, and mode choice in the context of airport ground access. While the work completed for ACRP Research Report 215 occurred prior to COVID-19, the research team's methods remain relevant as airports look for ways to attract customers and increase revenue. Given these changes, airport operators can still consider the specific tools, guidelines, and policy levers described in ACRP Research Report 215 to support their decision-making in a rapidly evolving travel environment during and after the pandemic.
