Microscopic simulation model calibration and validation for freeway work zone network - a case study of VISSIM

Microscopic simulation models have been widely accepted for evaluation of various transportation system design and traffic operations and management strategies. In that regard, the calibration and validation of simulation model is crucial for appropriate decision making process. This paper presents an application of previously developed microscopic simulation model calibration and validation procedure for a freeway work zone network. Multiple days of field data were collected to consider variability and these days were divided into calibration and validation datasets. The study results showed that the procedure was effective in the calibration and validation of a freeway work zone network
