Traffic Flow - History

History

Attempts to produce a mathematical theory of traffic flow date back to the 1920s, when Frank Knight first produced an analysis of traffic equilibrium, which was refined into Wardrop's first and second principles of equilibrium in 1952.

Nonetheless, even with the advent of significant computer processing power, to date there has been no satisfactory general theory that can be consistently applied to real flow conditions. Current traffic models use a mixture of empirical and theoretical techniques. These models are then developed into traffic forecasts, to take account of proposed local or major changes, such as increased vehicle use, changes in land use or changes in mode of transport (with people moving from bus to train or car, for example), and to identify areas of congestion where the network needs to be adjusted.

Famous quotes containing the word history:

    History is not what you thought. It is what you can remember. All other history defeats itself.
    In Beverly Hills ... they don’t throw their garbage away. They make it into television shows.
    Idealism is the despot of thought, just as politics is the despot of will.
    Mikhail Bakunin (1814–1876)

    I cannot be much pleased without an appearance of truth; at least of possibility—I wish the history to be natural though the sentiments are refined; and the characters to be probable, though their behaviour is excelling.
    Frances Burney (1752–1840)

    The history of modern art is also the history of the progressive loss of art’s audience. Art has increasingly become the concern of the artist and the bafflement of the public.
    Henry Geldzahler (1935–1994)
