JFK Airport Redevelopment Program, Queens, NY
Scope of Work
Traffic Data Collection │Capacity and Simulation Analysis │Traffic Impact Analysis │ QA/QC Audits│ Traffic Circulation Analysis │Level of Service (LOS) Sensitivity Analysis │VISSIM Models
JPCL has been involved in performing several different studies for the JFK Airport Redevelopment project. JPCL collected TMC, VCC, Speed Runs, and made QA/QC Comparisons, developed LOS for passenger wait times, conducted Qualitative Parking Garage Inventory, and identified Correlation Factors between passenger throughput and vehicle volumes. JPCL analyzed the impact of re-routing incoming traffic that entered the JFK Terminal 8 Lower Level by different vehicle classes, such as personal vehicles, buses, vans, taxis, and limousines. JPCL performed traffic simulations utilizing VISSIM software to analyze the traffic conditions at various intersections and provided insights and recommendations to improve the traffic flow conditions in the study area.
JPCL also performed Traffic Impact Analysis for the proposed facilities on the Airside and Landside Roadways at the airport. The study involved evaluating roadway capacity in the existing conditions, forecast of maximum trips, and traffic signal improvements to accommodate additional trips in the study area. For this purpose, the Synchro model was developed for the airside traffic analysis and a VISSIM model was used for the landside traffic demands and capacity evaluation. A sensitivity analysis was also performed to determine the maximum capacity of roadways on both airside and landslide for the proposed developments.
In addition, JPCL performed a Level of Service (LOS) sensitivity analysis for various traffic volume demand scenarios for five critical links in the proposed JFK Terminal 4 parking lot design. A VISSIM microscopic model was developed identifying links as either a multilane freeway segment or a weaving segment. A level of service sensitivity analysis was performed for various volume demand scenarios by applying percentage volume increments from 5% to 35% in the model. The calculated density (passenger cars/mile/lane) for each link was used to identify the LOS using the Highway Capacity Manual (HCM). A technical memorandum was prepared and presented to the agency with observations and recommendations based on the results of the sensitivity analysis performed.
