A third and last community meeting for North Siders to contribute to a Carnegie Mellon University "urban lab" study will be held Wednesday from 6:30 to 9 p.m. at the Children's Museum.

CMU architecture students are proposing ways to "mend disconnects within the neighborhood," said Flora Bao, one of the students.

The focus this semester has been on Allegheny West, Central North Side and East Allegheny.

Ms. Bao said students will compile a booklet with the schemes they devise.

They will include improvements to traffic flow around Allegheny Center, possibly breaking through the isolating circle it creates; boosting the presence of destinations such as the National Aviary, the Mattress Factory, the Children's Museum and Allegheny General Hospital; filling in deteriorated lots with homes to increase population and diversity; and encouraging more retail zoning.
