What We Do

Momentum works with foreign partners to share knowledge and best practices focused on seven key areas across all modes of transportation, all of which address overarching policy issues including sustainability, equity, and economic development:

Transportation Planning and Project Delivery

Transportation planning involves collaboration with government agencies, community stakeholders, private sector organizations, and others to develop strategies and policies to manage transportation systems. Good planning leads to good projects that are the foundation of an effective transportation system. Learn more about our Transportation Planning and Project Deliverywork.

Climate Change

The transportation sector is a leading emitter of greenhouse gas (GHG) emissions that contribute to climate change, but the sector is also affected by climate change. Rising temperatures and severe weather events can cause minor to catastrophic damage to transportation systems and infrastructure. A multimodal, holistic approach is needed to reduce GHG emissions, mitigate climate change impacts, and build a more resilient transportation system. Learn more about our Climate Change work.

Across all modes of transportation, government agencies strive for the continuous improvement of transportation safety. To implement a comprehensive and coordinated approach to transportation safety, government agencies rely on performance-based and data-driven measures; agencies also must also consider policies, evaluate emerging planning approaches, and assess design strategies. Learn more about our Safety work.

Cross-Border Mobility and Trade

Cross-border mobility and trade addresses the effective movement of people, goods, and services across international borders. Government agencies, businesses, and community stakeholders must coordinate to ensure the efficient and secure flow of trade across borders. Effective border transportation plans focus on connectivity for all modes of transportation to fully support trade and mobility. Learn more about our Cross-Border Mobility and Trade work.

Freight and Logistics

Freight and logistics planning is the process of coordinating and optimizing the movement of goods from one place to another, typically using multiple transportation modes. Government agencies can work with private sector organizations and other stakeholders to invest in infrastructure and develop plans that support improved freight and logistics activities. Effective freight and logistics planning can help to improve freight efficiencies, reduce freight’s environmental impacts, and ensure that freight supports sustainable economic growth for communities, regions, or nations. Learn more about our Freight and Logistics work.

Innovation and Technology

Emerging technologies and mobility options are shaping the future of the transportation sector. Transportation agencies can improve operations, enhance travelers’ experiences, ensure reliable service, and improve overall quality of life. Examples include zero-emission or automated vehicles, micro mobility, and “smart” cities. Learn more about our Innovation and Technology work.

Good Governance and Good Regulatory Practices

Governance refers to the government processes and practices through which decisions are made about shared issues, such as transportation. Governments often use regulations to establish rules and norms for transportation practices. Governments can exhibit “good governance” in the transportation sector through ensuring that decisions are made equitably, transparently, and sustainably, as well as by involving the public in the decision-making process. Learn more about our Good Governance and Good Regulatory Practices work.
