Urban transportation -- United States, Transportation planning, Traffic congestion -- Management
The net effects of sprawl or compact development on area-wide traffic congestion have been a subject of debate among transportation researchers.
This project aims to settle the debate using:
- Congestion data from the Texas Transportation Institute’s Urban Mobility Scorecard database;
- Compactness/sprawl metrics developed at the University of Utah.
Compact development may help at the margin, but the greatest reduction in congestion appears to be achieved through expansion of surface streets and higher highway user fees.
