Does Compact Development Increase Or Reduce Congestion?, Reid Ewing Oct 2017

Does Compact Development Increase Or Reduce Congestion?, Reid Ewing

TREC Project Briefs

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.
