چکیده مقاله:
Determining trip demand matrix is among the basic data in transportation planning. This matrix is derived by surveys,interviews with citizens or questionnaires that required time, money and manpower. Thus, in recent years, demandestimation methods based on network information is taken into consideration. In these methods with the informationincluding: volume, travel time, capacity of the links and initial demand matrix it is possible to estimate the demand matrix.In this paper, we removed the additional parameters in previous studies and used a simple solution to estimate the matrix.This paper proposes a Fuzzy-PFE estimation method that allows to improve the estimation performances of PFE estimator.The objective function presented based on the reduction of travel time and travel time of routs in networks is uncertain.The method is developed by fuzzy sets theory and fuzzy programming that seems to be convenient theoretical frameworkto represent uncertainty in the available data. The new model is the removal of iterative process of origin - destinationmatrix estimation using travel time and increase convergence of the model for the large-scale and congested networks byapplying little changes in the basic model. In this paper we used TRANSCAD Software to determine the shortest path inthe network and optimization of objective function is performed by CPLEX.
