The use of simulation models on the Central Artery/Third Harbor Tunnel Project

This paper discusses how simulation models are being used on the Central Artery/Third Harbor Tunnel Project to develop incident response plans and to evaluate the design of the Integrated Project Control System. This simulation effort is comprised of four phases: use of the INTEGRATION Network Simulation Model to develop incident response plans; (2) use of the MIT Dynamic Traffic Model to test and evaluate the proposed control system design; (3) further development of the MIT model to be used as a tool in the operations control center (OCC) for fine-tuning incident response plans; and (4) development of a concept for a future predictive simulation model to be used on-line in the OCC. The first two of these efforts are underway, the third is being evaluated, and the fourth represents a possible future implementation in the OCC.
