The purposes of this article is as follows:
A.
Traffic safety. The occurrence of accidents, and more frequently the fear or expectation that accidents or near accidents might occur, is often a leading problem. In some cases, these streets serve as primary pedestrian routes for school children, which tends to amplify these concerns.
B.
Traffic speed. Excessive speed is a frequent resident complaint. Vehicles driven at high speeds, even if only occasionally, are seen as a threat by thoughtless drivers to the peace, quiet, safety and quality of life within the neighborhood.
C.
Traffic volumes. As with speed, excessive amounts of traffic are also of major concern to residents.
D.
Noise and air pollution. Environmental issues play a great role in the basic quality of neighborhood life, particularly if a major percentage of the traffic stream is made up of larger and/or older vehicles, if street curvature or gradient is severe or if the pavement has a rough surface.
E.
Impacts on property. The presence of excessive traffic can discourage residents and lead to increased resident turnover and neighborhood instability. There is also some evidence that streets with greater auto accessibility may be more susceptible to residential crime.
