An Improved Calibration Method for VISSIM Simulation Model Of Signalized Intersection

To achieve high fidelity and credibility for a traffic simulation model, model calibration and validation are of utmost importance. The parameters calibration of microscopic traffic simulation models is a complex and systematic process. It is time-consuming and difficult to find the optimal values of the calibration parameters. A systematic calibration procedure based on orthogonal experiment is proposed. Six driving behavior parameters critical to the model accuracy are calibrated in the proposed procedure. Then, an example of the procedure application on a complex signalized intersection in Beijing is given. The average errors of queue length and traffic flow volume are used as the performance indexes in the example. Each scenario from the experimental design is run 10 times and the simulation result is recorded for each of the runs. The performance indexes based on simulation data are calculated to compare survey data. The results show the applicability and effectiveness of using the proposed procedure based on orthogonal experiment to calibrate the parameters in VISSIM.
