Quality of Life Study
The Quality of Life (QoL) Study is RTD's data-driven evaluation of progress toward meeting the FasTracks Program goals. The QoL Study focuses on the “quality of life” in the context of those areas most affected by transit improvements and those specifically addressed in the FasTracks Plan: mobility, environment, economic activity, development, and land use.
Transit-Oriented Development Projects
Development at and around the system's transit stations is an exciting element of the FasTracks program. As the Denver region's public transit agency, RTD plays an important role in the implementation of Transit-Oriented Development (TOD). TOD is characterized by a pedestrian-oriented environment that allows people to live, work, shop and play in places accessible by transit.
