A good approach for this, would be the use of electrically driven, driverless vehicles, called Automated People Movers (APM). An application of this, a so called Group Rapid Transit (GRT) system, has already been developed by the Dutch company 2getthere. However, for the specific use of such a system on airports, only the GRT vehicles are not sufficient. Use on airports asks for an infrastructure above ground level, to be combined with the existing buildings. Further, such an infrastructure should be sustainable, to make the GRT system fit in the future plans of airports. Therefore, this master’s graduation project is about the development of such an elevated infrastructure. In order to design this, the following question is being answered: What should a sustainable elevated system infrastructure for 2getthere’s GRT system at airports look like? An important part of this master’s project thesis, is the analysis. First, the different relevant aspects of ‘sustainability’ have been investigated. This resulted in the conclusion that sustainability does not only include the aspect of ‘planet’, but that also ‘people’ and ‘profit’ (in this case, mainly the profit of the airports) are of major importance for a sustainable design. Second, the principles and applications of APMs have been summarized. At the moment, there are only a few examples of (big, metro-like) APM systems. However, in many situations, a somewhat smaller APM system is more appropriate. GRT systems with their theoretical capacity of 10,800 passengers per hour are a good solutions for many of the transport demands at airports. Next to this good fit in terms of capacity, APMs have many sustainable aspects, that distinguish them from conventional public transport systems. The to-be-designed infrastructure needs to emphasize this. Thirdly, analysis of different aspects of airports led to the conclusion that GRT systems are the best suitable APMs for airports. GRTs can mainly be applied to connect different buildings and facilities, instead of being applied in buildings. As an example, a proposal for a spatial design for Schiphol is included. Further, the important aspects of designing an infrastructure have been explored. As the infrastructure has to be elevated, different bridging systems have been scrutinized. One of the conclusions was that the infrastructure has to be as light as possible, with as little foundation as possible and it has to be prefabricated. In short, the conclusions are that steel is better suitable than concrete for the construction. This all contributes largely to the sustainability of the infrastructure. Importantly, the road surface can be involved in generating energy. These four analysis chapters result in the vision that the elevated GRT infrastructure design should be as ‘minimal’ as possible. This is reflected in the design statement: The GRT system infrastructure should be like a culm of bamboo. The design vision was elaborated in a list of criteria. Then, this design vision and knowledge from the analysis phase are translated into ideas, focusing on the main structure of the infrastructure and its sustainability. These ideas are combined in the two principle solutions ‘less is more’ and ‘green corridor’. These two concepts are merged into the final design, that consists of a trail made of pultruded glass fiber reinforced plastic profiles, carried by a steel construction that serves as guide rail at the same time. The trail is placed on steel pillars, 4.5 m above ground level and is accompanied by an evacuation path. The entire route of the infrastructure can be constructed from 20 m long modules. Also, the design contains standardized curve, split and slope sections. Since the wheels of a GRT use only a narrow part of the track, there is room for solar panels in the middle, to gain energy for the vehicles. The final part of the report consists of evaluations. The design is first evaluated based on the list of criteria in general and on sustainability in particular. In an evaluation with an expert from Schiphol, the design was reviewed as a promising product, that could be successfully exploited by 2getthere. The evaluation results in a list of recommendations followed by a personal evaluation.
