2. 1. Foliated Transportation Networks - Evaluating feasibility and potential

   Author : Joakim Kalantari; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hybrid transportation systems; transportation network modeling; intelligent transportation systems.; transportation planning and control; transportation network simulation; transportation network optimization; Transportation networks; transportation network performance; mixed model transportation; transportation network efficiency;

   Abstract : Neither the critical role that transportation plays for economic activities nor its negative external effects can be denied. At the same time, the resources required to sustain and develop the transportation system to an adequate degree and at the required pace are limited. READ MORE

4. 2. Foliated Transportation Networks - Exploring feasibility and potential

   Author : Joakim Kalantari; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transportation network modeling; hybrid transportation systems; transportation network optimization; transportation network simulation; transportation planning and control; Transportation networks; mixed model transportation;

   Abstract : In transportation systems in general the issue of overcapacity coupled with low resource utilization has been identified for some time now. It has also been shown that the growth in transportation demand in the past is not absorbed by the existing overcapacity; rather the low levels of resource utilization are maintained. READ MORE

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

   Author : Toheed Ghandriz; Chalmers tekniska högskola; []
   Keywords : 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;

   Abstract : 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. READ MORE

6. 4. Transportation Mission-Based Optimization of Heavy Combination Road Vehicles and Distributed Propulsion, Including Predictive Energy and Motion Control

   Author : Toheed Ghandriz; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automation; electrified propulsion; long combination vehicles; electromobility; propulsion system tailoring; automated driving systems; optimal control; single-track and two-track vehicle models; predictive energy management and vehicle stability; motion control; longer heavier vehicles; vehicle stability; optimal energy management; total cost of ownership; optimization; transportation mission; heterogeneous heavy vehicle fleet; fleet sizing;

   Abstract : This thesis proposes methodologies to improve heavy vehicle design by reducing the total cost of ownership and by increasing energy efficiency and safety. Environmental issues, consumers expectations and the growing demand for freight transport have created a competitive environment in providing better transportation solutions. READ MORE

7. 5. On Battery Electric Vehicles: Driving Patterns, Multi-Car Households and Infrastructure

   Author : Niklas Jakobsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BEV; battery size; individual movement pattern.; Electro-mobility; GPS-logging;

   Abstract : The transportation sector is responsible for a quarter of all greenhouse gas emissions in Europe. Though the transport system may be difficult to change into a less polluting system, electric vehicles may be a possible approach. READ MORE
