In this paper a new formulation of within-day dynamic traffic assignment is presented, where a dynamic user equilibrium is expressed as a fixed-point problem in terms of arc flow temporal profiles. Specifically, it is shown that, by extending to the dynamic case the concept of network loading...

In this paper, we propose a new model for the within-day Dynamic Traffic Assignment (DTA) on road networks where the simulation of queue spillovers is explicitly addressed, and a user equilibrium is expressed as a fixed-point problem in terms of arc flow temporal profiles, i.e., in the infinite...

In this paper, we present a new nonstationary link-based macroscopic arc performance model with capacity constraints, derived from an approximate solution to the simplified kinematic wave theory which based on the assumption, often introduced in the algorithms solving Dynamic Traffic Assignment,...

The mathematical formulation of the problem of maximizing the green band in a two-way street is performed. In so doing, in addition to problems for which the bandwidths are unsplit, we consider cases in which the bandwidths in a single cycle, in one or both directions, are split into two...

A new approach to arterial progression optimisation, based upon the properties of periodicity in time and space of the system, gives rise to the concept of equivalent systems and module of the system, which allow us to devise a very rapid algorithm for solving a bandwidth maximisation problem....

This paper presents a dynamic user equilibrium for bus networks where recurrent overcrowding results in queues at stops. The route-choice model embedded in the dynamic assignment explicitly considers common lines and strategies with alternative routes. As such, the shortest hyperpath problem is...
