1. 21. Towards sustainable personal mobility with electric cars and buses

   Författare :Sven Borén; Göran Broman; Henrik Ny; Louise Ödlund; Maria Grahn; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strategic Sustainable Development; Transport Planning; Electric Vehicles; Testing; LCA; Mobility;

   Sammanfattning : The aim of this thesis was to explore if, and then how, electric cars and buses can contribute to sustainable personal mobility. Electric vehicles have increasingly been seen as a potential sustainable solution for the transport sector due to their high energy efficiency, close to zero emissions in the use phase, and the possibility to be powered by electricity from renewable resources.

3. 22. Lignocellulosic Ethanol Production Potential and Regional Transportation Fuel Demand

   Författare :Lilia Daianova; Jinyue Yan; Louise Trygg; Mälardalens högskola; []
   Nyckelord :Agricultural by-products; Straw; Bioethanol; Transport system; Greenhouse gases GHG ; Polygeneration system; Combined Heat and Power CHP ; Mixed Integer Programming MIP .; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Road traffic dominates in domestic Swedish transportation and is highly dependent on fossil fuels, petrol and diesel. Currently, the use of renewable fuels in transportation accounts for less than 6% of the total energy use in transport. LÄS MER

4. 23. Catching the Bus in Old Age - Methodological Aspects of Accessibility Assessments in Public Transport

   Författare :Gunilla Carlsson; Hållbar vardag och hälsa i ett livsperspektiv; []

   Sammanfattning : Engagement in daily activities is central for people’s health and well-being. Today, our activity arenas mostly cover great geographical areas, and to reach different activities we must travel. However, people with functional limitations are sometimes restricted in their travelling. LÄS MER

5. 24. Cost and financing of the sustainability transition of the Swedish road freight transport sector

   Författare :Elmira Parviziomran; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Godstransporter; Hållbar utveckling; Fossila bränslen; Fordon; Kostnader; Finansiering; Batterier; Sustainable development; Electric batteries; Vehicles; Freight and freightage; Fossil fuels; Sustainability transition; Decarbonization; Heavy-duty vehicles; Cost; Financing; Battery; Circular economy; Diesel fuels;

   Sammanfattning : The cost and financing of the road freight sector’s sustainability transition, driven by significant greenhouse gas (GHG) emissions and cost considerations, represent an urgent yet underexplored research focus. This study investigates the costs of fleet replacement with zero-emission powertrains, battery electric vehicles (BEVs) and fuel cell vehicles (FCVs), emphasizing cost variables that have been overlooked in transition research.

7. 25. Constructing Transit Corridors : The Politics of Public Transport Policy and Planning in Malmöhus and Skåne 1970-2020

   Författare :Jens Portinson Hylander; Robert Hrelja; Jamil Khan; Fredrik Pettersson-Löfstedt; Jane Summerton; Jonathan Metzger; Miljö- och energisystem; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Public transport; Rationality; power and politics; Planning theory; policy studies;

   Sammanfattning : Planning local and regional public transport in so-called ’transit corridors’ – i.e., to concentrate infrastructure and resources to few, but more attractive corridors in a city or a region – is commonplace in contemporary public transport planning. This has not always been the case, however. LÄS MER
