Andrew Breck joined Volpe in 2011. Applying a dual background in the natural and social sciences, he researches, analyzes, and synthesizes information to support strategic decisions, plans, and policies for a variety of customers. His work addresses diverse topics, including sustainability, energy, resiliency, vulnerable road user safety, and social equity. He recently led a Volpe team that supported the Federal Highway Administration (FHWA) in developing the FHWA Environmental Justice Reference Guide. The guide draws together information from diverse disciplines, strengthening and broadening the conversation on environmental justice while providing practical tips and tools for transportation agencies.
Breck has also developed resource management plans for a variety of clients, proposing options and weighing the costs and benefits of each approach. His analyses focus on monetary as well as non-monetary costs and benefits, such as ecosystem services and social outcomes. One example of a relevant transportation application for this type of analysis is assisting transportation agencies in evaluating methods for managing the right-of-way real estate that they own and maintain for safety, aesthetics, asset preservation, and other desired values.
