MICROSCOPIC SIMULATION MODEL CALIBRATION AND VALIDATION : A CASE STUDY OF VISSIM FOR A COORDINATED ACTUATED SIGNAL SYSTEM

This paper proposes a procedure for microscopic simulation model calibration and validation and demonstrates an example case study using real world traffic data from Route 50 on Lee Jackson Highway in Fairfax, VA. The proposed procedure consisted of nine steps: i) measure of effectiveness selection, ii) data collection, iii) calibration parameter identification, iv) experimental design, v) run simulation, vi) surface function development, vii) candidate parameter sets generations, viii) evaluation, and ix) validation through new data collection. The case study indicates that the proposed procedure appears to be properly calibrating and validating the VISSIM simulation model for the test-bed network
