It is situated in the middle of the roads Madrid-Bilbao and Barcelona-Santiago de Compostela, at the edge of the Iberian central plateau. It has about 180,000 inhabitants in the actual city and another 20,000 in the metropolitan area. It is the capital of the province of Burgos, in the autonomous community of Castile and León. Burgos was once the capital of the Crown of Castile. It has many historic landmarks, of particular importance; the Cathedral of Burgos (declared World Heritage Site by UNESCO in 1984), Las Huelgas Reales Monastery and Miraflores Charterhouse.

SUBMITTED TO IEEE TRANSACTION ON INTELLIGENT TRANSPORTATION SYSTEMS ON NOVEMBER 2014 1 A Hybrid Optimal Control Approach to Fuel Efficient Aircraft Conflict Avoidance Manuel Soler, Maryam Kamgarpour, Javier Lloret, and John Lygeros, Fellow, IEEE Abstract—We formulate fuel optimal conflict free aircraft the ATCOs would still be in the loop, and thus trajectories trajectory planning as a hybrid optimal control problem. The should also be cognitive friendly. This ensures high levels of discrete modes of the hybrid system capture the air traffic efficiency and safety via automation, yet accounts for human’s procedures for conflict resolution, e. g., speed and turn advisories. In order to solve problems of realistic dimensions arising from trust and acceptance. In this work, we propose an optimal air traffic sector planning, we formulate a numerically tractable control framework, consistent with the operational procedures approach to solve the hybrid optimal control problem. The of ATCOs, pilots and autopilots, for minimum fuel conflict approach is based on introducing binary functions for each mode, resolution in pre-tactical (20 minutes to one hour) trajectory relaxing the binary functions and including a penalty term on planning.

Furthermore, using data from Spanish airports, we empirically test this model obtaining the demand function according to the preferences of public authorities. The results show that the public budget, airport’s attributes or intermodal competition a¤ect to the demand for aircraft operations of regional public agencies. Finally, we propose an empirical method to determine the market power of airlines within these marketing agreements in a particular airport or route. 1 Introduction In recent years, some airports have experienced a signi…cant increase in air tra¢ c due to the liberalization in the air transport market. In some cases, this phenomenon has been related to the existence of new transport policy tools which aim to promote the use of airport infrastructure with idle capacity. In this way, an increasing number of regional airports have received the support of their regional governments through …nancial arrangements with air carriers in order to open new routes, as well as to provide advertising services linked to the permanence of the air carrier at a given airport. Indeed, airport managers have more incentives to negotiate long-term contracts with air carriers in order to reduce the risk of tra¢ c loss for their installations (Gillen, 2011).

  • European Hub Airports – Assessment of Constraints for Market Power in the Local Catchment and on the Transfer Market
    Technische Universität Dresden Fakultät Verkehrswissenschaften „Friedrich List” Institut für Wirtschaft und Verkehr DISSERTATION European Hub Airports – Assessment of Constraints for Market Power in the Local Catchment and on the Transfer Market zur Erlangung des akademischen Grades Doctor rerum politicarum (Dr. rer. pol.) im Rahmen des Promotionsverfahrens an der Fakultät Verkehrswissenschaften „Friedrich List“ der Technischen Universität Dresden vorgelegt von: Annika Paul, geb. Reinhold geb. am 30.09.1981 in Gifhorn Gutachter: Prof. Dr. rer. pol. habil. Bernhard Wieland Prof. Dr. rer. pol. Hans-Martin Niemeier Ort und Tage der Einreichung: Dresden, 23. Januar 2018 Ort und Tag der Verteidigung: Dresden, 04. Juni 2018 Abstract Airports have long been considered as an industry in which firms are able to exert significant market power. Nowadays, there is controversial discussion whether airports face a degree of competition which is sufficient to constrain potentially abusive behaviour resulting from this market power. The level of competition encountered by European airports has hence been evaluated by analysing the switching potential of both airlines and passengers between different airports, for example. The research within this thesis contributes to the field of airport competition by analysing the degree of potential competition 36 European hub airports face on their origin-destination market in their local catchments as well as on the transfer market within the period from 2000 to 2016. For this purpose, a two-step approach is applied for each market, with first analysing the degree of market concentration, using the Herfindahl Hirschman Index as a measure, for each destination offered at the hub airports and the respective development over time.

  • Regional Public Support to Airlines and Airports: an Unsolved Puzzle
    Regional public support to airlines and airports: an unsolved puzzle Ramón Núñez-Sánchez October 20, 2014 Abstract This paper proposes a structural model to explain the motivation of regional public authorities to arrange marketing agreements for route and tra¢ c development. Moreover, using data from Spanish airports, we em- pirically test this model obtaining the (inverse) demand function according to the preferences of public authorities. The results show the sensibility in the demand for aircraft operations of regional public agencies increases as the size of the airport also increases. Finally, we propose an empirical method to determine the market power of airlines within these marketing agreements in a particular airport or route. 1 Introduction In recent years, some airports have presented important growths levels of traf- …c due to the liberalization in the air transport market. In some cases, this phenomenon has been related to the existence of new transport policy tools which aim to promote the use of airport infrastructure with idle capacity. In this way, an increasing number of regional airports have received the support of their regional governments through …nancial arrangements with air carriers in order to open new routes, as well as to provide advertising services conditioned to the permanence of the air carrier at a given airport. Indeed, airport man- agers have more incentives to negociate long-term contracts with air carriers in order to reduce the risk of tra¢ c loss for their installations (Gillen, 2011). In Europe, these types of agreements among regional governments and air carriers have been controversial, especially for those full service carriers (FSCs) which have made a claim to the European Commission, asking whether those subsidies should not be considered as illegal.
