Nearly two-dozen representatives from southwestern Pennsylvania worked together to come up with ideas for how to improve transportation in the area.

The Regional Transportation Alliance of Southwestern Pennsylvania released its findings Wednesday in the report Imagine Transportation 2.0.

The alliance surveyed more than 500 community and governmental groups to build a list of seven broad overarching principles and “50 ideas to explore.”

The efficient movement of people and goods is one of the essential components of sustainable regions. So, too, is keeping public transportation both accessible and operative at the most efficient levels, according to William W. Millar, a nationally known expert in the fields of public transportation and transportation policy.

Millar spoke on these and other transportation issues at the University of Pittsburgh Tuesday during his lecture, “How Will We Travel in the Future? The Role of Transportation in Building Sustainable Regions."
