A modified Physarum-inspired model for the user equilibrium traffic assignment problem
The user equilibrium traffic assignment principle is very important in the traffic assignment problem. Mathematical programming models are designed to solve the user equilibrium problem in traditional algorithms. Recently, the Physarum shows the ability to address the user equilibrium and system optimization traffic assignment problems. However, the Physarum model are not efficient in real traf...
متن کاملA Physarum-inspired Model for the Probit-based Stochastic User Equilibrium Problem
Stochastic user equilibrium is an important issue in the traffic assignment problems, tradition models for the stochastic user equilibrium problem are designed as mathematical programming problems. In this article, a Physaruminspired model for the probit-based stochastic user equilibrium problem is proposed. There are two main contributions of our work. On the one hand, the origin Physarum mode...
متن کاملA bio-inspired algorithm for fuzzy user equilibrium problem by aid of Physarum Polycephalum
The user equilibrium in traffic assignment problem is based on the fact that travelers choose the minimum-cost path between every origin-destination pair and on the assumption that such a behavior will lead to an equilibrium of the traffic network. In this paper, we consider this problem when the traffic network links are fuzzy cost. Therefore, a Physarum-type algorithm is developed to unify th...
متن کاملA Schedule-based User Equilibrium Traffic Assignment Model
Equilibrium traffic assignment models exist to deal with a range of observational uncertainties. Perhaps the most well known is the stochastic user equilibrium model, incorporating random perceptual terms to represent components of drivers’ disutility that are not explained through observed attributes (Sheffi, 1985). The uncertainty represented by such a model is from the viewpoint of the model...
متن کاملStability of user-equilibrium route flow solutions for the traffic assignment problem
This paper studies stability of user-equilibrium (UE) route flow solutions with respect to inputs to a traffic assignment problem, namely the travel demand and parameters in the link cost function. It shows, under certain continuity and strict monotonicity assumptions on the link cost function, that the UE link flow is a continuous function of the inputs, that the set of UE route flows is a con...
