    Passenger-oriented Railway Traffic Re-scheduling: A Review of Alternative Strategies utilizing Passenger Flow Data2017Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Developing and operating seamless, attractive and efficient public transport services in a liberalized market requires significant coordination between involved actors, which is both an organizational and technical challenge. During a journey, passengers often transfer between different transport services. A delay of one train or a bus service can potentially cause the passenger to miss the transfer to the subsequent service. If those services are provided by different operators and those are not coordinated and the information about the services are scattered, the passengers will suffer. In order to incorporate the passenger perspective in the re-scheduling of railway traffic and associated public transport services, the passenger flow needs to be assessed and quantified. We therefore perform a survey of previous research studies that propose and apply computational re-scheduling support for railway traffic disturbance management with a passenger-oriented objective. The analysis shows that there are many different ways to represent and quantify the effects of delays on passengers, i.e.“passenger inconvenience”. In the majority of the studies, re-scheduling approaches rely on historic data on aggregated passenger flows, which are independent of how the public transport services are re-scheduled. Few studies incorporate a dynamic passenger flow model that reacts based on how the transport services are re-scheduled. None of the reviewed studies use real-time passenger flow data in the decision-making process. Good estimations of the passenger flows based on historic data are argued to be sufficient since access to large amounts of passenger flow data and accurate prediction models is available today.

    Movement of people and goods2013Inngår i: Understanding Complex Systems / [ed] Edmonds B., Meyer R. (eds), Springer Verlag , 2013, nr 9783319669472, s. 705-720Kapittel i bok, del av antologi (Fagfellevurdert)
    Abstract [en]

    Due to the continuous growth of traffic and transportation and thus an increased urgency to analyze resource usage and system behavior, the use of computer simulation within this area has become more frequent and acceptable. This chapter presents an overview of modeling and simulation of traffic and transport systems and focuses in particular on the imitation of social behavior and individual decision-making in these systems. We distinguish between transport and traffic. Transport is an activity where goods or people are moved between points A and B, while traffic is referred to as the collection of several transports in a common network such as a road network. We investigate to what extent and how the social characteristics of the users of these different traffic and transport systems are reflected in the simulation models and software. Moreover, we highlight some trends and current issues within this field and provide further reading advice. © 2017, Springer International Publishing AG.

    Ett samhälle utan transportutsläpp: de mjuka trafikanternas stad2019Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Dagens planering tar stor hänsyn till infrastrukturen när ett nytt område ska växa fram. Gatunätet placeras ut för att sedankompletteras med byggnader, parker och andra funktioner för att säkerställa att tillgängligheten är så bra som den kan bli.Normen under de senaste hundra åren har varit att gatanshuvudfunktion ska främja bilens framkomlighet och detsynsättet har präglat städernas utformning och vad som anses vara en gata. Detta projekt tittar på hur ett område kan se ut om man bortser från bilen och baserar utformningen på ett mer hållbart transportmedel som cykeln, samt vad som krävs för att möjliggöra detta och kompensera för det som går förlorat till följd av bilens uteslutande. Detta arbete kommer fokusera på cykelns fördelar ur olika perspektiv och undersöka hur den kan ta större plats i gatuanvändningens hierarki.Utifrån forskningen kommer olika gestaltningsförslag att tas fram för att synliggöra vilka fysiska attribut som en cykelorienterad stad eller stadsdel behöver innefatta för att kunna erbjuda effektiva transportmöjligheter. För att vidare konkretisera och exemplifiera principerna kommer förslagen att implementeras i ett nytt utvecklingsområde i Kungens kurva söder om Stockholm. En funktionsblandad bebyggelse föreslås tillsammans med en infrastruktur som fokuserar på gång och cykelns framkomlighet snarare än bilens.

    District Heating and CHP: A Vital Role for the Development towards a Sustainable Society?2012Inngår i: Latest trends in sustainable and green deveopment - Proceedings of the 3rd International Conference on Urban Sustainability, Cultural Sustainability, Green Development, Green Structures and Clean Cars (USCUDAR 12), WSEAS Press , 2012, s. 157-167Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In Sweden, district heating (DH) is quite well developed and is already mainly based on non-fossil fuels. Increased use of DH is therefore considered as a way of phasing out fossil energy for heating purposes. Furthermore, increased use of DH provides an increased basis for combined heat and power production (CHP). Considering that coal condensing is the marginal production of electricity in Europe, increased use of bio-fueled CHP leads to even greater reductions of global carbon dioxide (CO2) emissions. However, in a sustainable society, where there is no longer a systematic increase of CO2 (and no other sustainability problems), the benefits of DH are less obvious. The aim of this work is to explore the impact of DH and CHP in the development towards such a society. A local energy system is studied for five different time periods from 2010 to 2060 with different marginal technologies for electricity production. Results show that when the local energy utility co-operate with a local industry plant and invests in a new CHP plant for waste incineration the global CO2 emissions for the whole studied time period will be reduced with about 48 000 tonnes, which corresponds to over 100 % of the emissions from today’s system for the same time period. When considering that bio fuel is a scarce resource, and that the amount of CO2 emission linked to waste probably will be lower in sustainable society, the global CO2 emissions will be about 250% lower compared to the system of today. The studied DH related cooperation and introduction of CHP will reduce the system cost for the whole studied energy system with 2 500 MSEK for the studied period. In general, the results indicate that the modeled measures will not have any major advantages over other heating technologies in a sustainable society but that it can play a vital role for the development towards such a society.
