1. 1. Driving it home! Exploring and enhancing the adoption of eco-driving

   Författare :Helena Strömberg; Chalmers University of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; SAMHÄLLSVETENSKAP; HUMANIORA; ENGINEERING AND TECHNOLOGY; SOCIAL SCIENCES; HUMANITIES; pro-environmental behaviour; exploratory approach; behaviour change; interventions; eco-driving;

   Sammanfattning : One strategy to reduce the environmental impact of the transport sector is to increase the adoption of eco-driving among both professional and private drivers. Attempts to introduce eco-driving have though had varying success, and many questions remain to be answered. LÄS MER

3. 2. On optimal mission planning for conventional and electric heavy duty vehicles

   Författare :Ahad Hamednia; Chalmers University of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Logistics planning; Transport efficiency; Mission planning; Optimal control; Eco-driving; Model predictive control;

   Sammanfattning : Ever-growing energy consumption and CO2 emissions due to the increase in road transport are major challenges that attract international attention, especially policy makers, logistic service providers and customers considering environmental, ecological and economic issues. Other negative side-effects caused by the growth of the road transport are the extensive economic and social costs because of traffic congestion. LÄS MER

4. 3. Optimal Control of Electric Bus Lines

   Författare :Rémi Lacombe; Chalmers University of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Eco-driving; Electric buses; Bus bunching; Nonlinear programming; Optimal control; Model predictive control;

   Sammanfattning : Bus lines are inherently unstable systems, where any delay tends to be further amplified by the accrued passenger loads encountered at stops downstream. This self-reinforcing mechanism, when combined with the multiple sources of disturbances of an urban environment, can lead to the problem of bus bunching. LÄS MER

5. 4. Fuel-efficient and safe heavy-duty vehicle platooning through look-ahead control

   Författare :Valerio Turri; Karl H. Johansson; Nathan van de Wouw; KTH; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; platooning; eco-driving; look-ahead control; dynamic programming; distributed model predictive control; optimal control; autonomous vehicles; Electrical Engineering; Elektro- och systemteknik; Vehicle and Maritime Engineering; Farkostteknik;

   Sammanfattning : The operation of groups of heavy-duty vehicles at small inter-vehicular distances, known as platoons, lowers the overall aerodynamic drag and, therefore, reduces fuel consumption and greenhouse gas emissions. Experimental tests conducted on a flat road and without traffic have shown that platooning has the potential to reduce the fuel consumption up to 10%. LÄS MER

7. 5. Understanding processes and travel behaviour changes connected to electric vehicle adoption

   Författare :Joram H.M. Langbroek; Joel P. Franklin; Yusak Susilo; Jilian Anable; KTH; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportvetenskap; Transport Science;

   Sammanfattning : The use of electric vehicles (EVs) has the potential to increase the sustainability of the transport system, especially in case of unchanged or decreased car use, eco-driving and charging during hours of low electricity demand in case of an electricity generation mix with a large share of renewable energy sources. However, EVs still use much energy and EV-use does not solve problems regarding accessibility, social equity, traffic safety and has only a limited beneficial effect on liveability (e. LÄS MER
