Open Source Software

Advancing Transparency and Innovation Through Open Source

RSG helps advance transportation planning through our leadership in open-source software. We contribute code, governance, and technical guidance to tools that empower agencies to use transparent, defensible methods for planning and policy analysis. RSG’s involvement in the development of widely used open-source tools ensures these platforms continue to evolve in ways that meet the needs of and strengthen the broader transportation planning community.

Shaping the Shared Toolbox

From code contributions to governance, RSG helps build and maintain the open-source tools transportation agencies rely on for rigorous, defensible analysis.

Public agencies face rising expectations for transparency in how transportation planning tools are built, applied, and maintained.

  • Transparency is essential: Stakeholders want tools and methods that can be inspected, verified, and trusted, especially as decisions grow more data-driven.
  • Tools must evolve with the field: Agencies need frameworks that integrate diverse data sources, incorporate best practices, and avoid lock-in to proprietary systems.
  • Collaboration drives quality: Open-source tools succeed when many contributors advance the codebase, validate assumptions, and align development with emerging policy needs.

RSG helps agencies navigate these demands. We work within consortiums and multiagency initiatives to ensure open-source tools remain technically robust, intuitive to use, and responsive to the changing needs of the transportation planning community.

  • Shape the tools: Our experts contribute code, documentation, and governance that strengthen widely used open-source frameworks in modeling and analytics.
  • Embed transparency: We design methods and workflows that clients can clearly understand, reproduce, and defend, building trust across stakeholders.
  • Support better decisions: By aligning open-source tools with real-world data and agency priorities, we help planners produce results that are accurate, accountable, and ready for scrutiny.
  • Advance the state of the practice: Our leadership in open-source development fuels innovation across the community, ensuring tools evolve to meet today’s challenges and tomorrow’s opportunities.
