Mass Transit

The seamless integration of a transit system into its environment, whether urban or suburban, a railroad corridor, a commercial district, or an airport, is a great measurement of project success.  The system also must meet high standards for safety, reliability, security, and effectiveness in addressing mobility challenges, while representing value for the investment.  We work with you to develop transit solutions that not only meet these needs, but are also constructible and can be maintained into the future.

Our Expertise

Robust Transit Systems
We support the full life cycle of planning, designing, implementing, construction management, testing commissioning for new systems, rehabilitations, integrated line extensions, and state of the art enhancements to existing systems. We focus on accessible systems that support transit-oriented development of offices, housing, and commercial spaces. 

We’ve earned a national reputation as a leader in transit, rail, and bus through demonstrated innovation, such as the $2 billion Purple Line light rail project that winds through the Maryland suburbs outside of Washington, D.C., and the development of our TAROS suite of software for ensuring flexible and reliable operations.

Full Facility Integration
For the first time in six decades, people are driving less. Our integration of all types of transit infrastructure and facilities provides a solid foundation for meeting the demand for transit that’s readily available, efficient, and safe.  We combine a full spectrum of disciplines to develop the guideway elements, structures, retaining walls, track, civil and drainage solutions, and geotechnical solutions needed for connect transit systems and facilities. Since 1973, we’ve designed more than 100 vehicle maintenance facilities; many are winners of industry awards.

  • Rail Operations

    Rail Operations

    Manage the exceptional performance of your rail operations with the TAROS® suite of simulator software tools. TAROS® produces the accurate data you need to make decisions that impact reliability, validate proposed infrastructure improvements, and be ready for the unexpected.
  • Testing & Commissioning

    Testing and Commissioning

    We put the people and process in place to ensure a smooth transition from the construction to operation of your transit system. Our field personnel put processes, equipment, controls, and systems through operational and performance testing to guarantee that individual systems operate well on their own and as part of the overall system.
  • Safety & Security

    Security and Safety

    Safety and security issues are mission critical for the transit industry. With a host of federal and best practice documents creating a response framework, transit managers need to be diligent in their approach. Gannett Fleming performs all levels of transit safety and security planning, design, and construction management. Our team possesses in-depth knowledge of the issues that are on the minds of transit and rail operators. We can assist you in assessing and mitigating transit infrastructure vulnerabilities and help you understand your susceptibilities and risks. Read more about Security & Safety.
  • Sounds of Transit

    Sounds of Transit

    Noise and its impact is an understandable concern during the development of a new transit system within a community. Through early public early engagement, we can help you demonstrate actual transit sound levels in surrounding areas and mitigate local resistance to your project.
