Three-phase traffic theory is a theory of traffic flow developed by Boris Kerner between 1996 and 2002. [1] [2] [3] It focuses mainly on the explanation of the physics of traffic breakdown and resulting congested traffic on highways.

The first mathematical model of traffic flow in the framework of Kerner's three-phase traffic theory that mathematical simulations can show and explain traffic breakdown by an F → S phase transition in the metastable free flow at the bottleneck was the Kerner-Klenov stochastic microscopic traffic flow model introduced in 2002. [46]
Three-phase traffic theory is an alternative theory of traffic flow created by Boris Kerner at the end of 1990's [24] [25] [26] (for reviews, see the books [27] [28] [29]). Probably the most important result of the three-phase theory is that at any time instance there is a range of highway capacities of free flow at a bottleneck.
As demand approaches the capacity of a road (or of the intersections along the road), extreme traffic congestion sets in. When vehicles are fully stopped for periods of time, this is known as a traffic jam [3] [4] or (informally) a traffic snarl-up [5] [6] or a tailback. [7] Drivers can become frustrated and engage in road rage. Drivers and ...

Traffic modeling draws heavily on theoretical foundations like network theory and certain theories from physics like the kinematic wave model. The interesting quantity being modeled and measured is the traffic flow , i.e. the throughput of mobile units (e.g. vehicles ) per time and transportation medium capacity (e.g. road or lane width).
