  1. 1. High Capacity Transport för masstransporter i stadsmiljö för ökad transporteffektivitet och miljövinning

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Lena Walter; [2023]
    Nyckelord :Mass transport; transport efficiency; load classes; SWOT analysis; Massatransporter; transporteffektivitet; bärighetsklasser; SWOT-analys;

    Sammanfattning : En växande urban befolkning påverkar förutsättningarna för transporter i städer genom ökad trängsel. På grund av den höga byggnadstakten genereras stora mängder berg- och jordmassor som leder till ett högt antal byggrelaterade transporter som påverkar klimatet genom koldioxidutsläpp och som försämrar luftkvaliteten.

  3. 2. Techno-economic analysis and design of the charging infrastructure for Electric Heavy Vehicles in Oskarshamn

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Joan Cassany Espinosa; [2023]
    Nyckelord :Electrification; decarbonization; freight transport; heavy duty vehicle; battery electric truck; charging infrastructure; business model assessment; Elektrifiering; avkolning; godstransport; tunga fordon; batterielektrisk lastbil; laddinfrastruktur; affärsmodellsbedömning;

    Sammanfattning : Within the most pollutants industries, the energy sector is the most significant contributor to climate change, representing two-thirds of the total Greenhouse Gas (GHG) emissions. One of the main responsible for these emissions is transportation, which accounts for 26% of the world’s energy consumption, with crude oil-derived products providing more than 90% of this energy.

  4. 3. Evaluation of two different transport options for freight of heavy battery cells : a case study

    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Malin Andersson; Sara Fridhagen; [2022]
    Nyckelord :supply chain; sustainability; Lean; battery electric vehicle; transport; filling rate; truck; train; dangerous goods; tied-up capital;

    Sammanfattning : With the change that is taking place in the automotive industry, where production goes from producing internal combustion motor vehicles (ICE) to battery electric vehicles (BEV), this will lead to an increase in transportation of batteries. Batteries are components that are heavy, expensive, and classified as dangerous goods, which means higher demands on transport. LÄS MER

  5. 4. An Optimization Model for Electric Vehicle Routing with Tractor Swapping

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Alexander Strid; Daniel Liu; [2022]
    Nyckelord :Vehicle Routing Problem VRP ; tractor swapping; electric VRP; rich VRP; heavy goods vehicles; mixed-integer linear programming MILP ; applied mathematics; ruttoptimering; traktorbyte; elektriska lastbilar; tunga lastbilar; linjär heltalsoptimering; tillämpad matematik;

    Sammanfattning : The purpose of this thesis is to investigate how tractor swapping can be implemented in Vehicle Routing Problems (VRP) with electric heavy goods vehicles, and to evaluate how a model that allows for tractor swapping performs, in terms of schedule cost, against a model that does not. Hence, this thesis introduces a new rich VRP variant which includes tractor swapping, as well as time windows, pickup and delivery, and electric vehicles. LÄS MER

  7. 5. Early Classification of Automotive Radar Data Using LSTM

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Joel Styrélius; [2021]
    Nyckelord :;

    Sammanfattning : Advanced Driving-Assistance Systems such as blind-spot warning and collision avoidance are crucial systems for creating a safer and more sustainable traffic environment. A prerequisite for the safe operation of these types of systems is the classification of objects in the vicinity of the ego vehicle, based on data from automotive sensors such as lidars and radars.
