Land Use and Traffic Congestion is an investigation into the links among land use, travel behavior, and traffic congestion. Researchers focused on four transportation corridors in the Phoenix area: three older neighborhoods with relatively mixed, higher density land use, and one suburban area with lower density but high traffic volumes. The analysis suggested that the higher density corridors exhibited less congestion due to the greater mix of uses, shorter trip lengths, more travel by transit and non-motorized modes, and the presence of a secondary street grid system.

When we talk about Constitutional issues in relation to the Act, we are really asking is there a likelihood that it is unconstitutional in part or as applied to particular situations? The first risk is that some parts of it will be held to have been beyond the power of Congress to enact because they are not permissible exercises of the Interstate Commerce power. The second issue is the application of the Act to certain tracts of private property in a manner that would deprive that property of all beneficial use and constitute a taking of property. The third is that the mitigation demanded by the government as a condition for being allowed to take endangered species will exceed the power of government to demand because of a lack of a nexus in rough proportionality-- two tests that the Supreme Court has come up with in recent years.
