Analysis of Interrelated Network Improvement Alternatives

This proposed project will develop simulation and optimization methods for analyzing, selecting, and scheduling interrelated improvement alternatives for transportation networks. The interrelations may arise from changes in network flows and resulting user benefits, from constraints affecting multiple projects, and from various possible synergies. The methods will jointly analyze different types of alternatives, including new construction, post-disruption restoration, maintenance, operations, and pricing. The methods will analyze and seek to coordinate alternatives implemented by different agencies and jurisdictions, from different funding pools. They will consider funding mechanisms and constraints, equity factors, agency priorities, and uncertainties regarding demand growth, costs, budgets and implementation times. These methods are expected to improve the ability of various transportation agencies to efficiently allocate their limited resources, coordinate their development plans, deal with disruptions, and improve the capacity, service quality and overall performance of transportation systems.
