EQUILIBRIUM TRAFFIC ASSIGNMENT MODELS WITH VARIABLE DEMAND CONSIDERING TRAVEL TIME RELIABILITY

User equilibrium traffic network assignment with stochastic travel times and late arrival penalty

The classical Wardrop user equilibrium (UE) assignment model assumes traveller choices are based on fixed, known travel times, yet these times are known to be rather variable between trips, both within and between days; typically, then, only mean travel times are represented. Classical stochastic user equilibrium (SUE) methods allow the mean travel times to be differentially perceived across th...

Computation of Equilibrium Distributions of Markov Traffic-Assignment Models

A Traffic Network Design Scheme Based on Travel Time Reliability

On the basis of travel time reliability, this paper puts forward the concepts of absolute reliability and relative reliability to better assess road network; simultaneously, regional traffic road network reliability formula is deducted according to series and parallel connection of link, OD pair and road network. Finally, a bi-level programming model is established to optimize road network. The...

Real-time travel time estimation using macroscopic traffic flow models

This paper presents the estimation of travel time on highways based on macroscopic modelling. The focus is on real-time values as compaved to average or static values. The macroscopic models are used for distributed and timehpace lumped settings and corresponding travel time estimation functions and algorithms are developed. The implications of these algorithms for the implementation of various...
