  2. Traffic flow - Wikipedia

    en.wikipedia.org/wiki/Traffic_flow

    In transportation engineering, traffic flow is the study of interactions between travellers (including pedestrians, cyclists, drivers, and their vehicles) and infrastructure (including highways, signage, and traffic control devices), with the aim of understanding and developing an optimal transport network with efficient movement of traffic and minimal traffic congestion problems.

  3. QUIC - Wikipedia

    en.wikipedia.org/wiki/QUIC

    QUIC was developed with HTTP in mind, and HTTP/3 was its first application. [35] [36] DNS-over-QUIC is an application of QUIC to name resolution, providing security for data transferred between resolvers similar to DNS-over-TLS. [37]

  4. Three-phase traffic theory - Wikipedia

    en.wikipedia.org/wiki/Three-phase_traffic_theory

    In particular, in two-phase traffic flow models in which traffic breakdown is associated with free flow instability, this model instability leads to the F → J phase transition, i.e. in these traffic flow models traffic breakdown is governed by spontaneous emergence of a wide moving jam(s) in an initial free flow (see Kerner’s criticism on ...

  5. Fundamental diagram of traffic flow - Wikipedia

    en.wikipedia.org/wiki/Fundamental_diagram_of...

    The flow and capacity at which this point occurs is the optimum flow and optimum density, respectively. The flow density diagram is used to give the traffic condition of a roadway. With the traffic conditions, time-space diagrams can be created to give travel time, delay, and queue lengths of a road segment.

  6. Boris Kerner - Wikipedia

    en.wikipedia.org/wiki/Boris_Kerner

    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]

    en.wikipedia.org/wiki/Traffic_congestion...

    Synchronized flow is defined as congested traffic that does not exhibit the jam feature [J]; in particular, the downstream front of synchronized flow is often fixed at the bottleneck. Thus Kerner's definitions [J] and [S] for the wide moving jam and synchronized flow phases of his three-phase traffic theory [ 6 ] [ 7 ] [ 8 ] are indeed ...

    Used to determine the distance headway between a vehicle and its predecessor. One of the simplest model in this category is the Pipe's rule, the basic assumption of this model is "A good rule for following another vehicle at a safe distance is to allow yourself at least the length of a car between your vehicle and the vehicle ahead for every ten miles per hour (16.1 km/h) of speed at which you ...

  9. Biham–Middleton–Levine traffic model - Wikipedia

    en.wikipedia.org/wiki/Biham–Middleton–Levine...

    The Biham–Middleton–Levine traffic model is a self-organizing cellular automaton traffic flow model.It consists of a number of cars represented by points on a lattice with a random starting position, where each car may be one of two types: those that only move downwards (shown as blue in this article), and those that only move towards the right (shown as red in this article).
