Abstract This paper suggests an alternative approach to estimate the value of travel time (VTT) savings, using a case study with exogenous variation in costs and data from automatic traffic counts (ATC). With this revealed preferences approach, we address possible bias VTT estimates because self-selection. Compared used transport appraisals, results produce substantially higher VTT. Unfortunate...
In this paper we use a model-based traffic control approach to determine dynamic speed limits with the aim of reducing fuel consumption and emissions, while still guaranteeing small travel times. The approach we propose is based on model predictive control (MPC). MPC is a modelbased control design method that combines prediction and on-line optimization of a performance criterion over a given t...
terms of address as an important linguistics items provide valuable information about the interlocutors, their relationship and their circumstances. this study was done to investigate the change route of persian address terms in the two recent centuries including three historical periods of qajar, pahlavi and after the islamic revolution. data were extracted from a corpus consisting 24 novels w...
This paper uses a simulation-based optimization framework to investigate the added value of using higherorder distributional information from detailed traffic simulators to address signal control problems. In particular, this paper uses higher-order travel time distributional information to derive signal plans that account for travel time reliability. In order to derive computationally efficien...
Reliable location routing problem considers a location problem and a vehicle routing problem in order to select the optimal location of facilities and at the same time the optimal routes for vehicles considering the unexpected failure for facilities in which, all facilities may fail with a probability. In this paper, a bi-objective mathematical model has been developed to minimize the total cos...
