Variable Speed Limit Assignment
This is an upcoming approach of eliminating shockwave and increasing safety for the vehicles. The concept is based on the fact that the risk of accident on a roadway increases with speed differential between the upstream and downstream vehicles. The two types of crash risk which can be reduced from VSL implementation are the rear-end crash and the lane-change crash. Different approaches have been implemented by researchers to build a suitable VSL algorithm.

Famous quotes containing the words variable, speed and/or limit:
“There is not so variable a thing in nature as a lady’s head-dress.”
—Joseph Addison (1672–1719)
“Life is too short to waste
In critic peep or cynic bark,
Quarrel or reprimand:
‘Twill soon be dark;
Up, heed thine own aim, and
God speed the mark!”
—Ralph Waldo Emerson (1803–1882)
“Moreover, the universe as a whole is infinite, for whatever is limited has an outermost edge to limit it, and such an edge is defined by something beyond. Since the universe has no edge, it has no limit; and since it lacks a limit, it is infinite and unbounded. Moreover, the universe is infinite both in the number of its atoms and in the extent of its void.”
—Epicurus (c. 341–271 B.C.)
