Traffic wave

Traffic waves, also called stop waves, ghost jams, traffic snakes or traffic shocks, are traveling disturbances in the distribution of cars on a
Mitigation
It has been said[2][unreliable source?] that by knowing how traffic waves are created, drivers can sometimes reduce their effects by increasing vehicle headways and reducing the use of brakes, ultimately alleviating traffic congestion for everyone in the area.
However, in other models,[
History
The earliest theoretical model of traffic shock waves was offered by Lighthill and Whitham in 1955.[3] The following year Paul Richards independently published a similar model.[4] Both papers were based on fluid dynamics and the model is known as the Lighthill-Whitham-Richards model.[5]
