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.

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.
The Kerner-Klenov stochastic traffic flow model in the framework of Kerner's theory has further been developed for different applications, in particular to simulate on-ramp metering, speed limit control, dynamic traffic assignment in traffic and transportation networks, traffic at heavy bottlenecks and on moving bottlenecks, features of ...
In the study of traffic flow theory, the flow-density diagram is used to determine the traffic state of a roadway. Currently, there are two types of flow density graphs: parabolic and triangular. Academia views the triangular flow-density curve as more the accurate representation of real world events. The triangular curve consists of two vectors.
Braess's paradox is the observation that adding one or more roads to a road network can slow down overall traffic flow through it. The paradox was first discovered by Arthur Pigou in 1920, [1] and later named after the German mathematician Dietrich Braess in 1968.

Complex intersections with multiple vehicle lanes, bike lanes, and crosswalks are common examples of traffic engineering projects. Traffic engineering is a branch of civil engineering that uses engineering techniques to achieve the safe and efficient movement of people and goods on roadways.
