käyttäjättasapaino

Käyttäjätasapaino, often translated as user equilibrium, is a concept used in transportation planning and network analysis. It describes a state where no individual user of a transportation network can improve their travel time by unilaterally changing their route. This means that all used routes between any origin and destination are equally attractive in terms of travel time, and any unused route is less attractive.

The principle ofkäyttäjätasapaino is based on the idea that travelers will choose the route that minimizes their individual travel time. As more people use a particular route, congestion increases, and the travel time on that route rises. This leads some travelers to switch to less congested routes, redistributing traffic until a state of equilibrium is reached.

This concept is fundamental to traffic assignment models, which are used to predict how traffic will flow through a network based on origin-destination demand and the characteristics of the network. Understanding käyttäjätasapaino helps planners to assess the impact of new infrastructure, traffic management strategies, and changing travel patterns on the overall efficiency of the transportation system. It is also applied in other network contexts, such as telecommunications and energy distribution.
