Thesis (MEng)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: This thesis presents a robust, sampling-based path planning algorithm for commercial airliners that simultaneously performs collision avoidance both with intruder aircraft and terrain. The existing resolution systems implemented on commercial airliners are fast and reliable; however, they do possess certain limitations. This thesis aims to propose an algorithm that is capable of rectifying some of these limitations. The development and research required to derive this conflict resolution system is supplied in the document, including a detailed literature study explaining the selection of the final algorithm. The proposed algorithm applies an incremental sampling-based technique to determine a safe path quickly and reliably. The algorithm makes use of a local planning method to ensure that the paths proposed by the system are indeed flyable. Additional search optimisation techniques are implemented to reduce the computational complexity of the algorithm. As the number of samples increases, the algorithm strives towards an optimal solution; thereby deriving a safe, near-optimal path that avoids the predicted conflict region. The development and justification of the different methods used to adapt the basic algorithm for the application as a confiict resolution system are described in depth. The final system is simulated using a simplified aircraft model. The simulation results show that the proposed algorithm is able to successfully resolve various conflict scenarios, including the generic two aircraft scenario, terrain only scenario, a two aircraft with terrain scenario and a multiple aircraft and terrain scenario. The developed algorithm is tested in cluttered dynamic environments to ensure that it is capable of dealing with airport scenarios. A statistical analysis of the simulation results shows that the algorithm finds an initial resolution path quickly and reliably, while utilising all additional computation time to strive towards a near-optimal solution. / AFRIKAANSE OPSOMMING: Hierdie tesis bied 'n robuuste, monster-gebaseerde roetebeplanningsalgoritme vir kommersiële vliegtuie aan, wat botsingvermyding met indringervliegtuie en met die terrein gelyktydig uitvoer. Die bestaande konflikvermyding- stelsels wat op kommersiële vliegtuie geïmplementeer word, is vinnig en betroubaar; dit het egter ook sekere tekortkominge. Hierdie tesis is daarop gemik om 'n algoritme voor te stel wat in staat is om sommige van hierdie tekortkominge reg te stel. Die ontwikkeling en navorsing wat nodig was om hierdie konflik-vermyding-algoritme af te lei, word in die dokument voorgelê, insluitende 'n gedetailleerde literatuurstudie wat die keuse van die finale algoritme verduidelik. Die voorgestelde algoritme pas 'n inkrementele, monster-gebaseerde tegniek toe om vinnig en betroubaar 'n veilige roete te bepaal. Die algoritme maak gebruik van 'n lokale beplanningsmetode om te verseker dat die roetes wat die stelsel voorstel inderdaad uitvoerbaar is. Aanvullende soektog-optimeringstegnieke word geïmplementeer om die berekeningskompleksiteit van die algoritme te verlaag. Soos die aantal monsters toeneem, streef die algoritme na 'n optimale oplossing; sodoende herlei dit na 'n veilige, byna-optimale roete wat die voorspelde konflikgebied vermy. Die ontwikkeling en regverdiging van die verskillende metodes wat gebruik is om die basiese algoritme aan te pas vir die toepassing daarvan as 'n konflik-vermyding-stelsels word in diepte beskryf. Die finale stelsel word gesimuleer deur 'n vereenvoudigde vliegtuigmodel te gebruik. Die simulasie resultate dui daarop dat die voorgestelde algoritme verskeie konflikscenario's suksesvol kan oplos, insluitend die generiese tweevliegtuigscenario, die slegs-terreinscenario, die tweevliegtuig-met-terreinscenario en die veelvuldige vliegtuig-enterreinscenario. Die ontwikkelde algoritme is in 'n beisge (cluttered), dinamiese omgewing getoets om te verseker dat dit 'n besige lughawescenario kan hanteer. 'n Statistiese ontleding van die simulasie resultate bewys dat die algoritme vinnig en betroubaar 'n aanvanklike oplossingspad kan vind, addisioneel word die oorblywende berekeningstyd ook gebruik om na 'n byna optimaleoplossing te streef.

Airport road access wayfinding refers to a process in which a driver makes a decision to navigate using information support systems in order to arrive to airport successfully. The purpose of this research is to evaluate senior drivers’ behaviour of alternative airport road access designs. In order to evaluate the impact of wayfinding, the combination of simulated driving and completion of a questionnaire were performed. Quantitative data was acquired to give significant results justifying the research outcomes and allow non-biased interpretation of the research results. It represents the process within the development of the methodology and the concept of airport road access design and driving behaviour. Wayfinding complexity varied due to differing levels of road-side furniture. The simulated driving parameters measured were driving mistakes and performances of senior drivers. Three types of driving scenarios were designed consisting of 3.8 miles of airport road access. 40 senior drivers volunteered to undertake these tasks. The questionnaire was used as a supporting study to increase the reliability and validity of the research. Respondents who volunteered for the simulated driving test were encouraged to participate in the questionnaire sessions. The questionnaire was answered after each simulation test was completed. The Mean, Standard Deviation (SD) and Two-Way ANOVA test were used to analyse the results and discussed with reference to the use of the driving simulation. The results confirmed that age group has no significant effect of airport road access complexity design on driving behaviour. Although many studies have been conducted on wayfinding in general, a detailed evaluation on airport road access wayfinding network and driving behaviour in respect of senior drivers were still unexplored domains.

La gestion des aéroports a connu durant les trente dernières années de profondes évolutions. En effet, les enjeux de forte croissance du trafic aérien ont progressivement conduit à une logique d'amélioration qualitative. En outre, l’arrivée de nouveaux modes de gestion privés et de partenariats publics privés a renforcé le besoin de transparence.Dans ce contexte, les régulateurs sont devenus fortement responsables de l'organisation des aéroports. Ils doivent faire en sorte que les objectifs de service public soient pris en compte, en particulier dans leur nouvelle composante qualitative et doivent informer l'usager.La maîtrise des aéroports par les régulateurs est cependant rendue difficile : le déséquilibre d'information avec le gestionnaire, l'existence d'un oligopole ou encore la situation de monopole naturel sont autant d'éléments qui viennent affaiblir la position du régulateur. A la lumière de la théorie des contrats, l'analyse de modèles internationaux montre que les limites du mécanisme concurrentiel obligent à envisager une régulation plus poussée pour les aéroports que dans d'autres services publics.La mesure de performance par des indicateurs portant sur les résultats financiers et extra-financiers est un outil propre à améliorer cette maîtrise de la gestion par les régulateurs. En introduisant des mécanismes de circulation d'information, elle permet de mieux appréhender les évolutions de chaque service, mais aussi de les comparer entre eux. L'incitation par pseudo-concurrence peut ainsi s’appliquer efficacement, quel que soit le mode de gestion. Les indicateurs vont aussi servir à définir la qualité attendue dans la phase précontractuelle, puis à suivre et à piloter les résultats du service en phase d'exécution. Ils permettent enfin une communication vers les clients, rendant ainsi plus visibles des progrès du service qui restent souvent cachés. / Airport management has undergone profound changes in the last thirty years. Indeed, air traffic strong growth issues have gradually led to a goal of qualitative improvement. Besides, the arrival of new private management methods and public-private partnerships has strengthened the need for transparency.In this context, the regulators became strongly responsible for the organization of airports. They should ensure that public service objectives are taken into account, especially in their new qualitative component and must inform the passengers.However, managing airports is complicated for regulators due to several factors. Indeed, imbalance of information between the regulator and the airport manager, existence of oligopoly or even natural monopoly are elements that weaken the position of the regulator. In light of the contracts theory, the analysis of international models shows that the limits of the competitive mechanism force us to consider a further regulation for airports than for other public services.The performance measurement through indicators based on financial and extra- financial results is a tool to improve the control of airports management by regulators. By introducing mechanisms for flow of information, it helps to understand the evolution of each service, but also to compare them. The incentive for pseudo-competition can be applied effectively, regardless of the mode of management. The indicators will also be used to determine the quality expected in the pre-contractual phase, and to monitor and pilot the results of the services during the implementation phase. Finally, they allow communication to customers, making more visible the improvement of the services, which often remain hidden.

A impossibilidade da ampliação física suficiente para atender às perspectivas de crescimento da demanda de vôos em aeroportos como Congonhas (São Paulo), faz com que soluções alternativas para maior eficiência no processamento dos vôos sejam de grande interesse, destacando-se as soluções operacionais. Considerando-se a complexidade dos processos logísticos associados às operações aeroportuárias, a utilização da simulação em ferramentas de apoio à decisão permite a análise minuciosa do desempenho e eficiência do sistema de pátio de aeronaves. O objetivo principal dessa dissertação consiste em identificar os parâmetros e representar as operações do pátio em um modelo de simulação para análise do processo de atendimento das aeronaves e da influência de cada componente no seu tempo total. Desenvolvido em Arena® esse modelo utiliza os dados da movimentação real de aeronaves do aeroporto de Congonhas (a partir de fontes como os registros da torre, relatórios de planos de vôo, HOTRAN ou planejamento de pátio). Sua aplicação ao caso do aeroporto mostrou-se útil ao estudo do tempo de ocupação das posições (turn-around time), das esperas para atendimento e das taxas de ocupação dos recursos, assim como na determinação dos impactos das esperas em solo (ground holding) na capacidade total do sistema. Permitiu também a análise do processo de atendimento das aeronaves e o balanceamento do número dos equipamentos de pátio, aliada à animação detalhada dos serviços prestados no pátio desse aeroporto. Poderia, além disso, ser utilizado na avaliação de cenários de demanda, no teste de políticas de alocação de aeronaves às posições, na determinação do impacto do uso de slots, do compartilhamento de recursos ou da alteração de outras práticas operacionais. Em resumo, este modelo computacional oferece uma completa simulação dos serviços prestados no pátio de aeronaves buscando a melhor utilização dos recursos existentes e permitindo melhorias na capacidade do pátio, tanto com o enfoque de planejamento (configuração das posições) como operacional (avaliação da capacidade das posições). / The impossibility of physical expansion large enough to accommodate the anticipated growth in flight demand at airports such as Congonhas, São Paulo, has drawn interest to alternative solutions, especially operational ones, for the improvement of apron services efficiency. Considering the complexity of airport operation logistics, the utilization of simulation based decision support tools allows for the detailed analysis of the performance and efficiency in the airport apron system. The main objective of this dissertation is to identify the parameters that influence apron operations and to represent the apron operations in a simulation model in order to analyze the aircraft servicing process and the influence of each component in the servicing process total time. The simulation model was developed with Arena™ and uses real flight traffic data of operations at Congonhas airport (obtained from the tower logs, flight plan reports, HOTRAN and apron utilization planning documents). The application of the model to Congonhas airport was useful for the study of turn-around times, servicing waiting times, resource occupation rates, as well as the determination of ground holding impacts on the overall capacity of the system. The model was also used to analyze the airport’s apron servicing process and the adjustment of apron resources numbers, in addition to the detailed animation of those services. Moreover, this model could be used in the evaluation of demand scenarios, test of gate assignment rules, determination of impacts of slot time attribution, of sharing resources or other operational practices. In summary, this computational model offers a complete simulation of the apron services, with the goal of enabling better utilization of the airport’s existing resources and improvements in the apron capacity, both from a planning point of view (considering the apron configuration) and from an operational point of view (considering the capacity of each stand position).
