Many communities owe their existence to the routing first, of the railroad, later, of the highway, and then of the interstate. Transportation is fundamental to land values and the way communities grow.

This week’s guests are deeply involved in challenging old notions about transportation. Jeffrey Lubell is executive director of the Center for Housing Policy who argues that transportation costs should be considered in junction with housing costs to calculate the real cost of housing choices.

Diane Legge Kemp is designing transit facilities in and around Chicago to link them more intimately with the neighborhoods that surround them to encourage more people to take public transportation. Diane is principal and founder of DLK Design in Chicago.
