Assuming travelers' standard of choosing the path which perceives travel trait cost is minimized due to stochastic variations of link capacities,a stochastic user equilibrium assignment model based on travel trait is formulated.
In this view,based on the four-stage traffic model theory,using O-D estimation method and stochastic user equilibrium assignment model,with the purpose of achieving a realistic and reasonable result,this paper has designed the transit route adjustment and effect analysis procedure.
In this paper we studied the model with stochastic user equilibrium assignment for elastic demand,gave some related proof and designed the solving algorithm. A simple example was given to conduct programming computation.
Specially, as an example, the stochastic user equilibrium assignment model for the congested public transport network with elastic demand is proposed together with an effective solution algorithm.
For each approach a different optimization model and some solution algorithms are proposed; both models and algorithms are based on the assumptions of within-day static system and stochastic user equilibrium assignment models.
In this paper, a discretetime dynamic stochastic assignment model is proposed to meet the theoretical needs of traffic flow guidance systems.The model provides a discretetime description of the variations of flows on a road network during a day or a peak period.The traffic flow on links in the model is assumed as two parts:the free flow and a queue.The firstinfirstout discipline is enforced on all links at all periods of the day.The congestion effect at links and link junctions is taken acc...
In this paper, the system character of urban transit network and the principle of passenger how to choose route when congestion exists is analyzed,also uncertain factors are discussed. Further, link cost function is developed and a stochastic user equilibrium assignment model which satisfies the SUE(Stochastic User Equilibrium) principle is formulated, then GA(Genetic Algorithm) is cooperated with the model. ...
This paper proposes a stochastic user equilibrium assignment model for congested transit networks with multi class users. The corresponding equivalent mathematical programming problem is formulated, where the different perception of various user classes such as workers and shoppers on the path travel time is considered. An iterative algorithm is also put forward. Finally, an example is given to show that the proposed model and solution algorithm are rational and effectiv...
