1. 1. Towards electrified public bus transport : The case of Stockholm

   Författare :Maria Xylia; Semida Silveira; Maria Börjesson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric bus; charging infrastructure; optimisation; public transport; fossil-free; transport planning; Sweden; Energy Technology; Energiteknik;

   Sammanfattning : This thesis addresses the challenge of road transport electrification using a systems approach for the particular context of Stockholm’s public transport system. The objective is to identify the benefits of large-scale bus electrification on energy efficiency and greenhouse gas emissions, as well as the cost and planning considerations required for achieving such a shift.

3. 2. Sustainable Implementation of Electrified Roads : Structural and Material Analyses

   Författare :Feng Chen; Niki Kringos; Andreas Loizos; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrified road; Structural performance; Constitutive modelling; Asphalt; Dielectric loss.; Elektrifierade vägar; Strukturellt beteende; Konstruktivt modellerande; Asfalt; Dielektrisk förlust.; Byggvetenskap; Civil and Architectural Engineering; Transportvetenskap; Transport Science;

   Sammanfattning : Given the promise of the Inductive Power Transfer (IPT) technology for eRoad applications, the potential challenges for a successful integration of dynamic IPT technology into the physical road structure are explored extensively in this research work. The Finite Element Method (FEM) is selected for studying the structural performance of an eRoad under operational conditions. LÄS MER

   Sammanfattning : The topical issue of climate change has increasingly become important as scenarios indicate an increase of 2.5–7.8°C in the global mean temperature by the end of this century, if no greenhouse gas emissions are reduced. LÄS MER

5. 4. Transportation Mission Based Optimization of Heavy Vehicle Fleets including Propulsion Tailoring

   Författare :Toheed Ghandriz; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimization; heterogeneous heavy vehicle fleet; optimal energy management; propulsion system tailoring; Automated Driving Systems; electrified propulsion; total cost of ownership; electromobility; transportation mission; fleet sizing;

   Sammanfattning : Over decades freight vehicles were produced for a wide range of operational domains so that vehicle-manufacturers were not concerned much about the actual use-cases of the vehicles. Environmental issues, costumer expectations along with growing demand on freight transport created a competitive environment in providing better transportation solutions. LÄS MER
