Side constrained traffic equilibrium models— analysis, computation and applications

Side Constrained Traac Equilibrium Models| Analysis, Computation and Applications

We consider the introduction of side constraints for reening a descriptive or prescriptive traac equilibrium assignment model, and analyze a general such a model. Side constraints can be introduced for several diverse reasons; we consider three basic ones. First, they can be used to describe the eeects of a traac control policy. Second, they can be used to improve an existing traac equilibrium ...

On Side Constrained Models of Traffic

The basic model of traac assignment does not capture complex traac ow relationships such as interactions among vehicles on diierent road links, joint capacities on two-way streets, turning priorities in junctions, etc. Traditionally, such relationships are introduced implicitly through generalizations of the separable travel cost function of the basic model, and the reened models are usually st...

Constrained traffic equilibrium in routing

Use qij to denote the (i; j)-entry of the matrix Q (i; j = 1; 2). Then (Q) reads as (Q) = 0(1 + p 05)r 0 2 0(2 0 p 05)r + (1 + p 05) 2r + (1 0 p 05) 0(1 + p 05)r 0 2 (2) where r = (01+ p 05)q 11 0(2+ p 05)q 12 +2q 21 + (01+ p 05)q 22 : (3) Because any stabilizing controller can be obtained from the (2, 1)-and (2, 2)-entries of (2), we are interested in the set of r's of (3), that is, the ideal ...

A Dynamic Side-Constrained User Equilibrium Problem

Abstract: This paper incorporates two side constraints, namely, the link capacity and first-in-first-out (FIFO) constraints, into the dynamic user equilibrium (DUE) problem. Although the link capacity constraint has been addressed in the literature, its implications for the associated multiple-valued dual variables have not been properly drawn out and, thus, the matter is still subject to contr...
