Evaluating Mobility Impacts Of Construction Workzones On Utah Transportation System Using Machine Learning Techniques
Abbas Rashidi
Roadside construction – be it a detour, a closed lane, or a slow weave past workers and equipment – work zones impact traffic flow and travel times on a system-wide level. The ability to predict exactly what those impacts will be, and plan for them, would be a major help to both transportation agencies and road users. Funded by the National Institute for Transportation and Communities, the latest Small Starts project led by Abbas Rashidi of the University of Utah introduces a robust, deep…

How does transportation affordability vary between TODs, TADs, and other areas
Brenda Scheer Reid Ewing
Transit-oriented development, or TOD, could be the “poster child” for sustainable urban development. It concentrates land uses, including commercial and multi-family housing, near transit stations so as to reduce car dependency and increase ridership. The benefits are manifold; increased community health, positive economic impacts, less harm to the environment and potentially greater social equity.
But what about affordability? In exchange for all these benefits, do TOD residents spend more…
