Texans have been hearing about plans for high-speed rail between Dallas and Houston for more than a decade now. As the state's population continues to grow, leaders say residents could need to get comfortable with different modes of transportation to ease the movement of more than 30 million people daily.

Michael Morris, the director of transportation for the North Central Texas Council of Governments and Kara Kockelman, the Dewitt Greer Centennial Professor of Transportation Engineering at the University of Texas, are this week's guests.
