A Computational Study of Traffic Assignment Algorithms
Traffic congestion is an issue in most cities worldwide. One way to model and analyse the effect of congestion and other factors on route choice behaviour and to predict the impact of traffic management projects and transport policies is traffic assignment (TA). The most commonly used TA model is known as user equilibrium (UE), which is based on the assumption that all drivers want to minimise ...
متن کاملMethod of Parameter Calibration for Error Term in Stochastic User Equilibrium Traffic Assignment Model
Abstract—Stochastic User Equilibrium (SUE) model is a widely used traffic assignment model in transportation planning, which is regarded more advanced than Deterministic User Equilibrium (DUE) model. However, a problem exists that the performance of the SUE model depends on its error term parameter. The objective of this paper is to propose a systematic method of determining the appropriate err...
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 کاملA Partial Linearization Method for the Traffic Assignment Problem
This paper presents a new solution technique for the traffic assignment problem. The approach is based on an iteratively improved nonlinear and separable approximation of the originally nonseparable objective function, and resembles the Frank-Wolfe algorithm in the sense that the subproblem separates with respect to commodities. Since the singlecommodity subproblems are strictly convex, the new...
متن کاملComparison of assignment methods for simulation- based dynamic-equilibrium traffic assignment
This paper reports on the evaluation of alternative algorithms for dynamic, or time-varying, equilibrium traffic assignment. The algorithms are used for pre-trip assignment, which reflects driver familiarity with expected traffic conditions, and are appropriate for off-line applications which require a more detailed analysis – such as temporal network flows and sensitivity to traffic control me...
