Estimação da velocidade média em vias arteriais urbanas com uso do microssimulador VISSIM

Abstract

One of the main challenges in urban traffic microscopic modeling is the es ma on of the parameter of the driving behaviour models. The main objec ve of this paper is to propose a calibra on methodology for VISSIM for modeling urban arterial roads, focus-ing on the es ma on of the mean speed of cars and buses. The methodology was ap-plied in two urban corridors in Fortaleza, resul ng in calibra on errors of 10% and 13% and valida on errors of 19% and 9%. The second objec ve of this paper was to compare the proposed sequen al calibra on with the simultaneous calibra on, in which all pa-rameters are calibrated together based on the traffic measure of effec veness to be es- mated. The sequen al calibra on resulted in beEer es mates of the parameters, as this methodology decreases the chances of obtaining unrealis c sets of parameter values.
