User-Equilibrium Properties of Fixed Points in Dynamic Traffic Assignment∗
This paper considers the problem of dynamic traffic assignment under the principle that individual drivers will choose fastest paths, in the dynamic situation where path durations consist of time-dependent link travel times. Rather than constructing a unified model encompassing traffic dynamics and route choice, we decompose the model into an assignment mapping, which identifies the link travel...
متن کاملA Dynamic User Equilibrium Model for Traffic Assignment in Urban Areas
The growing traffic congestion in urban areas creates an urgent need for a better transportation planning. In this context, traffic assignment models can be used to help public authorities to test the impact of various transportation policies such as enlarging areas where bottleneck occurs, work start time flexbility etc. The representation of traffic variations over time allows dynamic transpo...
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 کاملFeedback control solutions to network level user-equilibrium real-time dynamic traffic assignment problems
A new method for performing Dynamic Traffic Assignment @TA) is presented which is applicable in real time, since the solution is based on feedback control. This method employs the design of nonlinear H, feedback control systems which is robust to certain class of uncertainties in the system. The solution aims at achieving user equilibrium on alternate routes in a network setting. 1.
متن کاملLiterature Review of Traffic Assignment: Static and Dynamic
Rapid urban growth is resulting into increase in travel demand and private vehicle ownership in urban areas. In the present scenario the existing infrastructure has failed to match the demand that leads to traffic congestion, vehicular pollution and accidents. With traffic congestion augmentation on the road, delay of commuters has increased and reliability of road network has decreased. Four s...
