Urban gondola lift systems are becoming a regular sight rather than a rarity throughout the globe. Authors attribute their increasing popularity to factors such as environmental sustainability, operational reliability and cost efficiency compared to other right-of-way transit solutions. Replacing conventional modes of transit with urban gondolas cannot however be achieved without tackling several operational challenges. As potential new operators often lack the human resources and knowledge base required to successfully man, operate and maintain systems, they turn to manufacturers for increased after-sale support. Companies of the Doppelmayr Garaventa Group, the world’s largest manufacturer of gondola lifts, responded to these demand patterns by offering complete operations & maintenance contracts which, among other services, include the delivery and installation of reserve components. Calculating the total cost of such components for the life cycle of a system however still proves to be demanding and requires new computational models to increase its efficiency. The applicative purpose of this paper was thus set to formulate a model that is capable of performing life cycle cost calculations for components of urban gondola lift systems, according to a set of criterion defined by industrial entities. Its research aim is accordingly to answer questions about how concurrent instruments are set up, what models does contemporary research regard as efficient in similar industries and whether these models are able to enhance life cycle cost calculation capability within the urban gondola lift market. These aims were achieved through an analysis of current company practices, followed by the formulation of two new model alternatives based on a review of contemporary scientific literature, and concluded by an iterative process wherein the two alternatives were compared to each other in terms of performance and then merged to combine the best performing features of each version. Through a second iteration, the merged model was then compared to current instruments and established as the superior choice, using industry criteria. The paper concludes by resolving the research questions it set out to answer and making further recommendations for the direction of future research and studies.

Linbana som kollektivt transportmedel i tätbebyggt område är i Sverige ett nytt fenomen. Med hänsyn till samhällets urbanisering och ambition att tillgodose bostadsbehovet genom förtätning, framstår linbana som ett lämpligt komplement till att förstärka befintlig infrastruktur. Framförallt på grund av det marginella "fotavtryck" anläggningen utgör på miljön. Linbanor är energieffektiva och miljövänliga transportalternativ som även ger framkomlighet i miljöer där andra transportsätt är för svåra eller för dyra att anlägga. I studien har frågor kring ersättning av markintrång och störningar som en linbana kan medföra granskats. Studien redogör för de generella ersättnings- och värderingsprinciper som berör detta område, samt hur dessa kan appliceras på linbanor i tätbebyggt område. Studien har genomförts med en juridisk metod, som innebär en fördjupning i lagtext, förarbeten och doktrin. För att kunna bedöma inverkan av störningarna har även vägledande rättsfall och praxis använts. Intervjuer har gjorts med en förrättningslantmätare samt ett tekniskt råd på avdelning 6, Svea hovrätt (mark- och miljööverdomstolen) för att vidga studiens referensramar av de tolkningar som gjorts. Av studien framgår att regler för intrångsersättning i expropriationslagen ska tillämpas, oavsett vilket lagrum som används för markåtkomsten. Avgörande där är den marknadsvärdeförändring intrånget medför. Effekten på marknadsvärdet av markintrång som utgörs av enbart vajer mellan stationer och pelarstöd, är svårare att bedöma än det intrång som görs för stationer och pelarstöd. Svårigheten ligger i bedömningen av hur marknadsvärdet förändras när fastigheten "urholkas" för linbanan. En linbana kan anläggas på höga höjder, vilket innebär att fastighetens möjlighet att nyttja utrymmet under vajern i de fallen inte begränsas i någon större utsträckning. Bedömning måste dock göras i det enskilda fallet. Gällande störningar framkommer problem kring hur olika störningar kan uppfattas samt hur dess sammantagna effekt ska bedömas. Då linbana som kollektivt transportmedel i tätbebyggt område är nytt inom Sverige har ännu inga rättsfall kring markintrång eller störningar prövats. För att kunna göra en bedömning av störningar har en rättsfallsanalys gjorts av rättsfall med verksamheter vars störning liknar de som kan uppkomma från linbanor. Resultatet visar att ämnet är svårbedömt. Att pröva linbanan i detaljplan kan därför vara en nödvändig åtgärd. Linbanan blir då prövad i sin helhet, och inom ramen för detaljplan främjas en bra dialog med berörda sakägare och medborgare i allmänhet. / A gondola lift as a means of public transportation system is a new phenomenon in Sweden. In view of the urbanization and society’s ambition to accommodate the urgent need of housing through a concentration of the city, a gondola lift stands out as a suitable compliment for the existing infrastructure. Above all because of the small "footprint" the structure makes on the environment. As a transportation system, gondola lifts are energy efficient, environmentally friendly and provides accessibility where other transportation systems are too difficult or too expensive to build. The study has looked at questions of compensation for the property encroachments and environmental disturbances a gondola lift might cause. The study gives further details about the general principles of compensation and valuation regarding this area, and also how these principles can be applied to gondola lifts in urban areas. The study has been done using a legal methodology, which involves a deeper understanding of the law, government bills and doctrine. Guiding- and precedent court cases has been analyzed in order to make an assessment about the influence of the environmental disturbances. Interviews has been done with a cadastral surveyor at the Gothenburg municipality office and with a technical adviser at the environmental court of appeal, in order to broaden the perspectives of the interpretations made in the study. The study infers that the compensation rules of encroachment in the law of expropriation should be applied, no matter which law is used to expropriate for the gondola lift. Decisive when determining the compensation is the change in market value caused by the encroachment. It´s harder to estimate the effect on market value caused by encroachment of the cable only, than for encroachment of the station buildings and pillars. The difficulty lies in the estimation of the change in market value when the expropriated property is "hollowed" in favor of the gondola cable. A gondola lift can be built very high, which means that a property in those cases aren´t restricted in any large extent regarding the use of the property directly below the cable. Although, assessments must be done for each individual case. Regarding the different disturbances, problems occur around the way they are perceived and how the overall effect of different disturbances should be assessed. Because gondola lifts as a public transportation is so new, there hasn´t been any legal cases tried about its encroachment or disturbances. In order to make an assessment about disturbances, a court case analysis has been done using cases about activities which disturbances are comparably similar to the once caused by a gondola lift. The result of the study shows that this assessment is hard to do. A necessary proceeding might be to try out the gondola lift in a detailed zoning plan. The gondola lift is then tested as a whole, including the effects of disturbances and encroachment. The framework of a detailed zoning plan also promotes the dialog with the parties concerned as well as with the other citizens.
