- Terminal Reconstruction Traffic Engineering
To address aging infrastructure, flight delays and increased passenger demands, Delta Air Lines, the largest carrier at LaGuardia Airport, has embarked on a multibillion-dollar overhaul of its terminal building. This busy and congested airport needs numerous upgrades to address congestion, traffic access and ITS challenges. Partnering with Delta Air Lines and working closely with the Port Authority of New York and New Jersey, our team evaluated interim and proposed landside multilevel roadway changes for arrival and departure levels, curbside pick-up operations and taxi/for-hire vehicle staging areas to optimize traffic operations within the vicinity of the terminal.
The project included development of Vissim simulations and parameters pertaining to the proposed entrance and frontage road system for the terminal during each stage of construction. That task required the evaluation of existing traffic conditions, development of seasonal adjustment factors, projection of traffic to future years based on flight schedules, and redistribution of traffic onto the proposed frontage road design. The team balanced traffic flow diagrams for the proposed frontage road design utilizing a seasonal adjustment factor and traffic projections. From that effort, Vissim models were developed to evaluate all interim roadway stages and keep the busy airport running smoothly. Because of unique traffic patterns for personal vehicles, taxis and transportation-as-a-service vehicles, each user type was counted independently and accounted for in the model.
To obtain the data needed for the traffic modeling, the team collected airport-wide traffic data. They are coordinating the work in conjunction with the Central Terminal Building (CTB) that is under construction by the LaGuardia Gateway Partners joint venture.
