DEVELOPMENT AND TESTING OF INTRAS, A MICROSCOPIC FREEWAY SIMULATION MODEL, VOLUME 1: PROGRAM DESIGN, PARAMETER CALIBRATION AND FREEWAY DYNAMICS COMPONENT DEVELOPMENT

This series of volumes documents the work performed to adapt a freeway simulation model for studying freeway incidents. The resulting program, INTRAS (INtegrated TRAffic Simulation), is a vehicle-specific time-stepping simulation designed to realistically represent traffic and traffic control in a freeway and surrounding surface street environment. This volume describes the detailed capabilities of INTRAS and its structural and procedural attributes. The calibration of traffic descriptive parameters are presented herein. The development of the simulation components which model the car-following lane changing and vehicle generation aspects of freeway traffic are also included. (FHWA)
