Or the Salt Lake City Region: What would be the implications of a policy that prohibits freeway capacity expansions.

For the Salt Lake City Region: What would be the implications of a policy that prohibits freeway capacity expansions:
~ On mobility (The ability to travel)
~ On Accessibilty (The ability to reach destinations)
~ Land Use patterns and Urban Form
~ On environmental Quality

Assume that the money saved by not expanding roads was spent in other ways (of your choosing) to either improve mobilty or accessibilty. ( MY choosing is to improve Mobilty by investing the money in alternative modes of transportation)

At what point does freeway capacity expansion become counterproductive (Consider environmental sustainablilty & other goals)

If you were to recommend to each city one land use policy to reduce travel demand or improve accessibilty in the salt lake city region, what would that policy be?
( Increase Density. Increase Mixed use properties. Place user taxes during peak hours, and takes the proceeds and invest in alternative transportation & a more cennected street grid)
