Research Highlights

Is Transit-Oriented Development Affordable for Low and Moderate Income Households?

Reid Ewing Nicole Iroz-Elardo , Arlie Adkins
Transportation and land use planning, as a field, is shifting away from segregated uses connected by highways and streets to more compact, mixed-use developments connected by high-quality transit. This new paradigm has brought special attention to transit-oriented developments (TOD), which are sometimes touted as being among the most affordable, efficient places to live. But how affordable are they, and who has the power to effect change? Is Transit-Oriented Development Affordable for Low… Read More

Does Compact Development Increase or Reduce Traffic Congestion?

Reid Ewing Shima Hamidi
It is now widely held, even among many state transportation departments, that you cannot “pave your way out of congestion” (at least in the long run) due to highway induced traffic and highway induced development (sprawl). Therefore, any solution to highway congestion must be multi-faceted and must, in particular, reduce the need for so much vehicular traffic. From years of other research, we know that compact development that is dense, diverse, well-designed, etc. reduces vehicle miles… Read More
