Interstate Highway System - Standards

Standards

The American Association of State Highway and Transportation Officials (AASHTO) has defined a set of standards that all new Interstates must meet unless a waiver from the Federal Highway Administration (FHWA) is obtained. One almost absolute standard is the controlled access nature of the roads. With few exceptions, traffic lights (and cross traffic in general) are limited to toll booths and ramp meters (metered flow control for lane merging during rush hour).

Famous quotes containing the word standards:

    If one doesn’t know one’s own country, one doesn’t have standards for foreign countries.
    Johann Wolfgang Von Goethe (1749–1832)

    Our ego ideal is precious to us because it repairs a loss of our earlier childhood, the loss of our image of self as perfect and whole, the loss of a major portion of our infantile, limitless, ain’t-I-wonderful narcissism which we had to give up in the face of compelling reality. Modified and reshaped into ethical goals and moral standards and a vision of what at our finest we might be, our dream of perfection lives on—our lost narcissism lives on—in our ego ideal.
    Judith Viorst (20th century)

    The home is a woman’s natural background.... From the beginning I tried to have the policy of the store reflect as nearly as it was possible in the commercial world, those standards of comfort and grace which are apparent in a lovely home.
    Hortense Odlum (1892–?)
