My small town did this 20 or 30 years ago with a number of residential streets that were commonly [ab]used for shortcuts. They erected barriers that consist of a curb across the roadway and a series of three or four "no entry" and "dead end" signs. Inconvenient, but it stops through traffic. Tucson and Phoenix have another alternative. The cities are built with the main roads being a large grid. Subdivision roads are twisty and higgledy-piggledy. It's almost always too inefficient to cut through a subdivision to bother trying.
