1. 1. Assessment of aggregate structure in porous asphalt using X-ray computed tomography

   University essay from KTH/Väg- och banteknik

   Author : Mari Haagenrud Matsson; Malex Love Valdemar Åkerblom; [2023]
   Keywords : Tomography; non-destructive testing; destructive testing; air voids content; aggregate size distribution; porous asphalt;

   Abstract : X-ray computed tomography is a technique that has been successfully utilized to characterize internal microstructure of asphalt mixtures. The city of Linköping (Sweden) developed an action plan to reduce noise; accordingly KTH and VTI developed a method to determine air void content in porous asphalt using x-ray computed tomography and an image processing software called ImageJ.

3. 2. Road traffic noise simulations based on 3D city models

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Wenjing Liu; [2023]
   Keywords : 3D city model; 3CIM; CNOSSOS-EU; noise simulation; city noise evaluation; data tailor; FME; SoundPLAN; Geomatics; Earth and Environmental Sciences;

   Abstract : Urban development and densification cause noise problems that can have a negative impact on human health. In 2002, the European Union (EU) stated the European Noise Directive (END) with the purpose to evaluate environmental noise levels (including the sources road, railway, and air traffic) in the member states every 5 years.

4. 3. Randomized heuristic scheduling of electrical distribution network maintenance in spatially clustered balanced zones

   University essay from KTH/Geoinformatik

   Author : Carolina Offenbacher; Ellen Thornström; [2022]
   Keywords : Capacitated Vehicle Routing Problem; Electrical distribution network; Heuristic algorithm; Scheduling; Handelsresandeproblemet; Eldistributionsnätverk; Heurustik algortim; Schemaläggning;

   Abstract : Reliable electricity distribution systems are crucial; hence, the maintenance of such systems is highly important, and in Sweden strictly regulated. Poorly planned maintenance scheduling leads unnecessary driving which contributes to increased emissions and costs. READ MORE

5. 4. Scaling up electric vehicles in India A focus on Maharashtra state, Mumbai Market formation and demand side policies

   University essay from Lunds universitet/Internationella miljöinstitutet

   Author : Oana Arseni; [2021]
   Keywords : India; Electric cars; Demand innovation policies; Market diffusion; Technology innovation systems; Social Sciences;

   Abstract : Governments around the world have begun to adopt measures in support of electric vehicles. The supply push policies have been traditionally studied leaving the demand side innovation policy without much investigation. Therefore, policy makers lack institutional knowledge and policy experience. READ MORE

6. 5. Mobility-as-a-Service and Electrification of Transport : A Study on Possibilities and Obstacles for Mobility-as-a-Service in Stockholm and Implications for Electrification of Vehicles

   University essay from KTH/Energiteknik

   Author : Albert Petersson; [2020]
   Keywords : ;

   Abstract : Increasing urbanization drives the need for cities to make transport more efficient, both to meet climate goals as well as creating an attractive living environment for its residents, with less congestion, noise and local pollution. As vehicles are increasingly electrified, further innovations will be needed in order to meet environmental, social and economic sustainability targets, and a more efficient use of vehicles and public transport is central in this endeavor.
