Essay Example on Provides a cost effective way of testing and evaluating different scenarios

 The network can be coded in a Network Editor that is bundled with the simulation model and can then be transferred to the simulation model The Network Editor is designed to simplify network coding In some cases the network can be coded in simulation or optimization models and can be transferred exported to other simulation models This procedure is mainly used when multiple softwares are required for the analysis and optimization of the network Sometimes due to the simplicity of the Network Editor the study network is coded in one model and then transferred to another model If this method of coding the network is used the user should be aware of the features elements that may be altered or missed during the transfer process Calibration Simulation models need to be calibrated before they are used for testing future scenarios since an un calibrated model might lead to skewed results Calibration involves changing some of the default parameters used in the simulation model so that it reflects the conditions observed in the study area As previously mentioned the movement of traffic in a simulation model is governed by different logics Simulation models provide the user with different parameters to fine tune the logic and other aspects of the model Examples of these parameters include minimum headway minimum acceleration rate minimum deceleration rate maximum acceleration rate etc These parameters are give
