Applications of ASDE-X Data to the analysis of airport surface operations
… Airport Surface Detection Equipment, Model-X (ASDE-X) has been installed at over 30 airports in the US as a safety device. The applications of the data being captured by these systems are far broader than just promoting safety. In this thesis, it will be demonstrated how ASDE-X data can be …

Determining the Location of Runway Exits Using Airport Surface Detection Equipment
<p>Airport surface detection equipment, such as ASDE-X, is used by thirty-five commercially operated airports throughout the United States. ASDE-X is responsible for the safe monitoring of aircraft movements as well as ground support vehicle operating on the airfield. Like most radar-based …

Analysis of approach stability and challenges in operational implementation of RNP approach procedures
… at four airports were analyzed using radar (ASDE-X) data, of which 364 (3.29%) were identified as RNP procedures. Of all approaches analyzed, two non-RNP cases were identified as unsafe, while there were no unsafe RNP cases. However, due to the relatively low number of RNP approaches …

Estimation of Runway Throughput with Reduced Wake Separation, Runway Optimization, and Runway Occupancy Time Consideration
… Airport Surface Detection Equipment Model X (ASDE-X) for analysis. The Runway Exit Design Interactive Model (REDIM) is used to optimize the runway exit locations and reduce ROT. The runway throughput and safety factors are generated from a Monte Carlo runway simulator. This thesis focuses on …

Estimation of Runway Throughput with Reduced Wake Vortex Separation, Technical Buffer and Runway Occupancy Time Considerations
… Airport Surface Detection Equipment, Model X (ASDE-X) data set. The analysis uses a modified version of the Quick Response Runway Capacity Model (RUNSIM). The main contributions of the study are: 1) identifying the technical buffer between in-trail arrivals and regenerate them in RUNSIM; 2) …

The influence of runway occupancy time and wake vortex separation requirements on runway throughput
… on Airport Surface Detection Equipment Model-X (ASDE-X) aircraft surveillance data. The findings of this study indicate that runway occupancy does not necessary scale with aircraft size. Small aircraft often occupy the runway as long as large aircraft, which limits the potential for reduced …

Runway Exit Speed Estimation Models
… geometry parameters define the type of exit. The ASDE-X data provides the observed exit speeds at the point of curvature for these exits. This study examines a few models with observed exit speeds as the response variable and exit geometry as the predictor variables.

Development of Aircraft Wake Vortex Dynamic Separations Using Computer Simulation and Modeling
… on Airport Surface Detection Equipment Model X (ASDE-X) data records at ORD during a 10-month period in the year 2016, a 3-month period at DEN, and a 4-month period at LGA. Results indicate that further reducing wake vortex separation distances from the FAA's proposed RECAT II static matrix, of 2 …

Airport Performance Metrics Analysis: Application to Terminal Airspace, Deicing, and Throughput
The Federal Aviation Administration (FAA) is continuously assessing the operational performance of the National Airspace System (NAS), where they analyze trends in the aviation industry to help develop strategies for a more efficient air transportation system. To measure the performance of various …

Incorporation of Causal Factors Affecting Pilot Motivation for Improvement of Airport Runway and Exit Design Modeling
This research aims to improve the design and placement of runway exits at airports through analysis and modeling of the effects that exogenous causal factors have on pilots' landing behavior and exit selections. Incorporating these factors into modeling software will strengthen the software's …
