  2. Flow network - Wikipedia

    en.wikipedia.org/wiki/Flow_network

    A flow must satisfy the restriction that the amount of flow into a node equals the amount of flow out of it, unless it is a source, which has only outgoing flow, or sink, which has only incoming flow. A network can be used to model traffic in a computer network, circulation with demands, fluids in pipes, currents in an electrical circuit, or ...

  3. Traffic flow (computer networking) - Wikipedia

    en.wikipedia.org/wiki/Traffic_flow_(computer...

    In packet switching networks, traffic flow, packet flow or network flow is a sequence of packets from a source computer to a destination, which may be another host, a multicast group, or a broadcast domain. RFC 2722 defines traffic flow as "an artificial logical equivalent to a call or connection."

  4. 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.

  5. Transport network analysis - Wikipedia

    en.wikipedia.org/wiki/Transport_network_analysis

    A transport network, or transportation network, is a network or graph in geographic space, describing an infrastructure that permits and constrains movement or flow. [1] Examples include but are not limited to road networks , railways , air routes , pipelines , aqueducts , and power lines .

  6. Braess's paradox - Wikipedia

    en.wikipedia.org/wiki/Braess's_paradox

    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.

  7. Three-phase traffic theory - Wikipedia

    en.wikipedia.org/wiki/Three-phase_traffic_theory

    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.

  8. Network traffic simulation - Wikipedia

    en.wikipedia.org/wiki/Network_traffic_simulation

    Network traffic simulation usually follows the following four steps: [1] [2] Modelling the system as a dynamic stochastic (i.e. random) process; Generation of the realizations of this stochastic process; Measurement of Simulation data; Analysis of output data

  9. Traffic model - Wikipedia

    en.wikipedia.org/wiki/Traffic_model

    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).
