SIMULATION STUDIES FOR AN URBAN TRAFFIC CORRIDOR

The report describes the salient features of the SCOT (Simulation of Corridor Traffic) model and a successful calibration and validation. SCOT is a computer model that may be applied to an urban traffic corridor and will simulate vehicular traffic on freeways, including on and off ramps, and urban streets. Vehicles are treated microscopically on the arterial street system and macroscopically as platoons on the freeway. Output statistics for each simmulated link include numbers of vehicles discharged, total times of travel, average occupancy, and average occupancy, and average speeds for specified time intervals. Calibration and validation data collected via photographic techniques on a 1.2 mile test network of the Dallas North Central Expressway are described. A demonstration of the origin-destination (O-D) traffic assignment capability of the model is described.
