A General Simulation Model for Use with Real Freeway Data to Perform Congestion Prediction--Phase 3

Description: The overall goal of this project is to create a method for predicting traffic congestion on freeway corridors. This report documents the calibration of the model and demonstrates its verisimilitude across full days and over 10 miles. In addition, it provides a demonstration of the utility of the model by testing its ability to perform simulation of vehicle behavior under unusual conditions. Inter-vehicle communication to improve safety is simulated, and the resulting safety and congestion reduction that can be gained by sharing vehicle states is demonstrated.
