Gulfton, in southwest Houston, is home to a large immigrant community where many residents get around on foot, including walking to bus stops.

But during a study of the Gulfton neighborhood, researchers with Rice University’s Kinder Institute found that over a third of the street segments they surveyed didn’t have sidewalks.

“Sidewalk availability matters but in addition to that the condition of the sidewalk is very important,” said Dian Nostikasari, one of the researchers who worked on the project.
