Integrated simulation and optimization in airfield networks
… airfield networks considering gate location and taxiway network information. By using the integrated simulation results, an improved dynamic programming model is established to solve the runway exit location problem. The simulation model uses aircraft kinematic functions coupled with individual …

Evaluating Flight Crew Decision-Making Through Part 121 Taxi Operations
… to enter a turn during taxi operations based on taxiway intersection angle and surface contamination. Additionally, this study explored whether there was a way to connect ASRS and ADS-B.</p> <p>Eighty-eight flights were split into four different groups based on their taxiway intersection angle …

Airport surface traffic optimization and simulation in the presence of uncertainties
… may be mitigated by optimizing runway and taxiway schedules. In prior research, runway scheduling algorithms and taxiway schedule optimization models have been developed independently, but they are closely related in airport operations. This motivates the development of a fast and efficient …

A knowledge base for rehabilitation of airfield concrete pavements
… design rehabilitation alternatives for a runway, taxiway or an apron. The AIRfield PAvement Consultant System (AIRPACS) uses the knowledge of planners, constructors, airfield managers and designers to solve difficult jointed plain concrete pavement (JPCP) design problems. This expert system …

Pilot Perception of Light Emitting Diodes Versus Incandescent Elevated Runway Guard Lights
… meaning of the signs, markings and lights on the taxiways and runways through a questionnaire that was developed with the FAA. Experiment 2 evaluated pilot perception of LED lighting compared to current incandescent elevated runway guard lights.</p> <p>The meaning of airfield lights is not often …

Development of Optimization and Simulation Models for the Analysis of Airfield Operations
… the Network Assignment Problem (NAP) for taxiway operations, and a simulation model for the evaluation of current or proposed ATC system in detail. For the ASP, we develop a mathematical model and apply the Reformulation-Linearization-Technique (RLT) of Sherali and Adams to construct an …

A Model to Convert Airport Geographic and Geometric Information into a Node-Link Network
… model, a standalone computer application, called Taxiway Toolkit, is developed to improve the Airfield Delay Simulation Model (ADSIM+).

Integrated airport capacity and delay model: computer package of the Federal Aviation Administration advisory circular 150/5060-5
… to predict airport hourly capacities and delays~ taxiway hourly capacity, gate group hourly capacity, overall airport hourly capacity, and annual service volumes. The possibility to replace the existing Federal Aviation Administration Advisory Circular 15015060-5 in the future was also explored. …

Modeling and control of airport departure processes for emissions reduction
… queue, and the congestion delay due to ramp and taxiway interactions. The dependence of the taxi-out time on these factors is analyzed and modeled. The performance of the model is validated through a comparison of its predictions with observed data at Boston's Logan International Airport (BOS). A …

Development of a pavement life cycle assessment tool for airfield rehabilitation strategies
… for three candidate rehabilitation strategies on Taxiway A and B at O’Hare International Airport in Chicago, IL: rubblization with mill/asphalt inlay, precast concrete panel replacement, and full depth reconstruction of existing concrete pavement structure. An extensive literature review and …

Development of techniques for rapidly assessing the local air quality impacts of airports
… (AERMOD). Meteorological, emissions, runway, and taxiway/terminal data for simulations were obtained from various sources. The RDMS was applied to obtain local-scale PM2.5 concentrations and exposures for the year 2006 for 191 U.S. airports that accounted for 95% of U.S. air passenger traffic. The …

Application of aircraft sequencing to minimize departure delays at a busy airport
… measures can be taken at the gate, on the taxiway system or at the runway queue to minimize departure delays and/or the cost of unavoidable delays. This cost includes needless fuel consumption and noxious emissions. In this thesis, we focus primarily on runway queue optimization. The first …

On the control of airport departure operations.
This thesis is focused on airport departure operations; its objective is to assign a value to surface surveillance information within a collaborative framework. The research develops a cooperative concept that improves the control of departure operations at busy airports and evaluates its merit …
