This project translates research into practice through developing two practitioner-ready tools using findings from NITC project #1401 “Mobility for the People: Evaluating Equity Requirements in Shared Mobility Programs”. In “Mobility for the People,” we confirmed our hypotheses that while many US cities implement shared mobility program equity requirements, specific requirements range dramatically. In addition, many requirements are not supported by data collection efforts and evaluation… Read More

The Effects of Commuter Rail on Population Deconcentration and Commuting: A Salt Lake City Case Study

Joanna Ganning
The Wasatch Front is a rapidly growing metropolitan area situated in a region with natural features that extraordinarily limit growth. The Wasatch Front Mountains constrain growth on one side while the Great Salt Lake and the Oquirrh mountains constrain the other. Among the nation’s worst winter inversions occur along the Wasatch Front, whereby high-pressure weather systems trap the air, and all the pollution added by humans, in the valley. The inversions produce red air quality days and… Read More
