Wardrop Equilibrium¶
In game theory and operations research, a Wardrop equilibrium is a concept developed by John Glen Wardrop for the prediction of traffic patterns in transportation networks that are subject to congestion.
Core Idea¶
Wardrop Equilibrium is treated here as the recurring social sciences, humanities, and arts identity summarized by this source-grounded definition: In game theory and operations research, a Wardrop equilibrium is a concept developed by John Glen Wardrop for the prediction of traffic patterns in transportation networks that are subject to congestion. In game theory and operations research, a Wardrop equilibrium is a concept developed by John Glen Wardrop for the prediction of traffic patterns in transportation networks that are subject to congestion. The idea of traffic equilibrium originated as early as 1924, with Frank Knight.
Scope of Application¶
-
Wardrop's first principle. It states: The journey times in all routes actually used are equal and less than those that would be experienced by a single vehicle on any unused route.
-
Wardrop's first principle. The traffic flows that satisfy this principle are usually referred to as "user equilibrium" (UE) flows, since each user chooses the route that is the best.
-
Wardrop's first principle. Specifically, a user-optimized equilibrium is reached when no user may lower his transportation cost through unilateral action.
-
Wardrop's first principle. A variant is the stochastic user equilibrium (SUE), in which no driver can unilaterally change routes to improve his/her perceived, rather than actual, travel times.
-
Wardrop's second principle. Wardrop's second principle, now known as "system optimal" or "social Wardrop equilibrium" states that at equilibrium, the average journey time is at a minimum.
Clarity¶
A clear use of Wardrop Equilibrium names the carrier, the operative relation, and the conditions under which the source treats the identity as present. The minimal definition is In game theory and operations research, a Wardrop equilibrium is a concept developed by John Glen Wardrop for the prediction of traffic patterns in transportation networks that are subject to congestion.
Manages Complexity¶
Wardrop Equilibrium compresses multiple social sciences, humanities, and arts details into a stable diagnostic relation. The source shows both the central mechanism—specifically, a user-optimized equilibrium is reached when no user may lower his transportation cost through unilateral action.—and the practical consequence—the Frank–Wolfe algorithm improves on this by exploiting dynamic programming properties of the network structure, to find solutions with a faster form of iteration.
Abstract Reasoning¶
- Type the carrier. Identify the social sciences, humanities, and arts entities to which the claim applies.
- State the relation. Use the source-grounded identity: In game theory and operations research, a Wardrop equilibrium is a concept developed by John Glen Wardrop for the prediction of traffic patterns in transportation networks that are subject to congestion.
- Check operation and conditions. Economists and modellers have argued that it can be achieved with marginal cost road pricing, or by a central routing authority dictating route choices. 4.
Knowledge Transfer¶
Within the home domain. Knowledge about Wardrop Equilibrium transfers literally when a new case preserves the same carrier type, relation, and recognition test. It states: The journey times in all routes actually used are equal and less than those that would be experienced by a single vehicle on any unused route. The traffic flows that satisfy this principle are usually referred to as "user equilibrium" (UE) flows, since each user chooses the route that is the best. Beyond the home.
