Reduced gradient algorithm for user equilibrium traffic assignment problem

, 2020
A path-based algorithm is developed for the static traffic assignment problem (TAP). In each iteration, it decomposes the problem into origin-destination (OD) pairs and solves each subproblem separately using the Wolfe reduced gradient (RG) method.

Traffic assignment: Equilibrium models

Proceedings of the Institution of Mechanical Engineers, Part I: Journal of Systems and Control Engineering, 2001
The formulation of static traffic assignment models, with variable and fixed demand, based on Wardrop's first principle, are presented for deterministic and stochastic models. The main algorithms used to obtain solutions for these network equilibrium models are given for each class of assignment problems.

Joint Planning of EV Fast Charging Stations and Power Distribution Systems With Balanced Traffic Flow Assignment

IEEE Transactions on Industrial Informatics, 2021
To tackle the challenges introduced by the fast-growing charging demand of electric vehicles (EVs), the power distribution systems (PDSs) and fast charging stations (FCSs) of EVs should be planned and operated in a more coordinated fashion.

Multimodal traffic assignment with traffic emission effects

Proceedings of the Institution of Civil Engineers - Engineering Sustainability, 2016
Traffic emissions are one of the most serious issues that affect urban sustainable development. Due to the heavy pollution from cars, public transport, including electric bicycles, has been regaining its proper position. A multimodal traffic equilibrium model with emission effects (MTEEE) is presented that considers energy use per person and pollutant

Link-Based System Optimum Dynamic Traffic Assignment Problems in General Networks

Operational Research, 2019
Most current system optimum dynamic traffic assignment (SO-DTA) models do not contain first-in-first-out (FIFO) constraints and are limited to single-destination network applications.

Real-time Traffic Assignment Using Engineered Customizable Contraction Hierarchies

ACM Journal of Experimental Algorithmics, 2019
Given an urban road network and a set of origin-destination pairs, the traffic assignment problem asks for the traffic flow on each road segment. Common solution algorithms require a large number of shortest-path computations.

On Dynamic Traffic Assignment [PDF]

, 1982
Traffic assignment is one of the most important steps in the mathematical theory of traffic flow and there is a lot of literature dealing with this subject (confer to Potts and Oliver (1972) or Florian (1976)). But almost all the papers have in common that only a static version of the assignment or the traffic equilibrium problem is treated. This means

Traffic Assignment Model with Environmental Traffic Capacity

ICCTP 2011, 2011
Based on the model of mobile pollutant emissions, environmental factors are embedded into a traffic assignment model in this study. Basic requirements for modeling are put forward considering urban environmental traffic capacity (ETC), while the countermeasures for link impedance function modeling including environmental factors are proposed.

A treatise on traffic assignment

Regional and Urban Economics, 1974
Abstract So far some economists have studied the pattern of traffic assignment theoretically and empirically. But it seems that there are few proper stochastic or statistical models for analyzing the traffic assignment problem on the base of an economic theory.
