This article describes the development of a microscopic computer simulation model, SIMSIO (SImulation Model of Signalized Intersection Operations). The various ways of modeling traffic behavior are discussed and the selection and calibration of these mechanisms with field observations are described. Validation studies show that SIMSIO provides a good representation of actual conditions. SIMSIO can provide a flexible and efficient experiment analysis tool which can be used to evaluate signal timing, geometry design and traffic management of signalized intersections, as well to test as new technologies and concepts.
