Speed values specific to a given circumstance can be obtained with the same formula using the appropriate reference constants specific to the circumstance.

VMS systems were deployed at least as early as the 1950s on the New Jersey Turnpike.

A chicane (/ ʃ ɪ ˈ k eɪ n /) is a serpentine curve in a road, added by design rather than dictated by geography. Chicanes add extra turns and are used both in motor racing and on roads and streets to slow traffic for safety.
Unsafe at Any Speed: The Designed-In Dangers of the American Automobile is a non-fiction book by consumer advocate Ralph Nader, first published in 1965.
