D13.4 , EBSF 2 - Gothenburg: Demonstration Results
- 2018
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The Gothenburg demonstration team has implemented and tested three (3) technological innovations (TIs), listed below according to the name and coding agreed with the EBSF_2 evaluation team and described in the following sections, namely: New energy-efficient heating solution for electric buses (TIGot1). In an electric driven vehicle the on-board energy consumption for heating is of higher importance compared to a diesel or hybrid driven vehicle, since there is much less surplus heat due to the high efficiency of the system.TIGot1 has tested the efficiency of a heating solution for electric buses that is driven by electricity and biofuels instead of diesel. Attractiveness and efficiency of innovative external and internal design of electric buses (TIGot2) A new driveline means the possibility to create new vehicle design. Four fully electric buses and seven plug-in hybrid buses (for comparison) that operate a new bus line in Gothenburg, line 55, have been demonstrated and evaluated. Attractiveness of innovative bus stop designs (incl. indoor) and interaction between bus and bus stop designs (TIGot3). Electrification offers new opportunities for creating innovative solutions for the interface between public transport and the urban environment, in terms of new types of bus stops, including an indoor stop. TIGot1 belongs to the EBSF_2 topical area “Energy Strategy and Auxiliaries”, TIGot2 to “Vehicle Design and TIGot 3 to “Interface between Bus and Urban infrastructure”. The team has shown a 60% decrease in the energy consumption for heating by installing an air-to-air heat pump, added insulation in key areas, and updated control systems. This equals a 17% reducton in overall energy use for an electric bus under normal operating conditions in Gothenburg. In terms of attractivness of buses and bus stops the fully electric bus line that has been implemented in Gothenburg has proven to be very popular with the travellers, as well as the drivers. Key benefits are the silent, low vibration, comfortable and well kept buses; the competent and friendly bus drivers; and the innovative and welcoming bus stops. Not the least people with reduced mobility stated that the buses and bus stops were easily accessible and declared it “the best bus ever”. Nevertheless some issues were found, not the least in terms of how to integrate the bus stops better in the city. The project clearly has shown that in order for bus stops to become something more than just a place to wait, both placement in the city and the cooperation of the surrounding businesses are of vital importance.

D17.6. Code of Practice for New Design Options of the Exterior and Interior Design and Layout of Buses and its Interface with the Platform
- 2018
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The EBSF 2 project has developed and tested, both in simulations and in field trials, different design solutions for (electric) buses and bus stops as well as the interface between the two. The results show that electrification can have a potentially huge positive impact on comfort, safety, accessibility, as well as the general impression of the public transport system. Simulations show that a number of design details impact efficiency and perception such as; large doors, big open areas around doors, absence of obstructions between door and seat/wheelchair position, etc. Results also demonstrate the importance of considering carefully the interplay between bus design, bus stop design, and e.g. rules for boarding. Simulations are here an important design tool. The EBSF 2 project has furthermore demonstrated the the feasibility and potential of indoor bus stops. Overall, electric buses, almost completely silent and without local emissions, offer new possibilities to progress towards a bus system that is more integrated with the city and everyday activities.

Patterns of use, perceived benefits and reported effects of access to navigation support systems: an inter-European field operational test
- 2015
-
Ingår i: IET Intelligent Transport Systems. - : Institution of Engineering and Technology (IET). - 1751-9578 .- 1751-956X. ; 9:8, s. 802-809

Tidskriftsartikel (refereegranskat)abstract
- The study presents findings regarding drivers' patterns of use, attitude towards, and reported effects of access tomature nomadic navigation support systems. Three different systems were tested by 582 drivers in four-field operationaltests for a period of six months. A majority of the participants used the support system for trips where the route/destination was unfamiliar but there were also other use scenarios. The main benefits entailed convenience andcomfort. Reported effects involved increased possibilities to choose the route according to preferences; a decrease inthe time it took to reach destinations and in the distance covered to reach the destination. One in four reported adecrease in fuel consumption attributed an increased compliance with speed limits and/or that driving around andsearching for the correct route to reach the desired destination could be avoided. A majority reported ‘no change’regarding the number of journeys made by car. Reported effects (whether increases or decreases) were howeversmaller than expected before the trial.

The paradox of public acceptance of bike sharing in Gothenburg
- 2016
-
Ingår i: Proceedings of the Institution of Civil Engineers: Engineering Sustainability. - : Thomas Telford Ltd.. - 1478-4629 .- 1751-7680. ; 168:6, s. 101-113

Tidskriftsartikel (refereegranskat)abstract
- Bike sharing is one of the most promising urban planning interventions to facilitate an all-necessary transition towards a more sustainable transport paradigm. Regardless of the fact that hundreds of schemes run in more than 50 countries worldwide, bike sharing is still moderately investigated by research. This paper reports on a primarily quantitative study of 558 responses that was set to frame attitudes reflecting public acceptance towards the rapidly expanding bike-sharing scheme in Gothenburg (Styr & Ställ), in an attempt to identify the ‘formula for success’. The respondents generally believed that Styr & Ställ is a pro-environmental, inexpensive and healthy transport mode, which complements the city’s public transport services and promotes a more human-friendly identity for Gothenburg. Even the respondents that self-reported a small (or no) likelihood to use bike sharing were positive towards the scheme. This means that they recognise that bike sharing has a significant pro-social potential and is not a system favouring a particular road-user segment over others that might not be interested or able to use it. The fact that the majority of the respondents do not use the scheme and yet its popularity is still vast indicates that there is much potential for more use in real terms.

Turning Interaction Design Students Into Co-Researchers: How We Tried This and Somewhat Failed
- 2015

Ingår i: Proceedings of the 17th International Conference on Engineering and Product Design Education (E&PDE15). - 9781904670629 ; , s. 194-199

Konferensbidrag (refereegranskat)abstract
- There are many potential benefits of involving university students in research (as researchers, not subjects). It can help students to increase their retentive knowledge in the subject they study, and also develop research skills such as problem framing and analysis. While disciplines such as psychology and medicine have a tradition of students contributing to research publications, Design and Product Development does not. This indicates an untapped potential for researchers in these fields to more actively engage their students in their work. In the spring of 2014, we made an effort to involve Interaction Design master's students in our research. It was in a Product Development course on "User Requirements Elicitation". The research itself dealt by comparison with the effectiveness of two research methods; namely, individual interviews compared to group interviews. During the course, students in groups made a quantitative and qualitative comparison of the two methods. It was clear that the students did not appreciate this initiative. Their opinion was that it did not have a high enough "pay-off" in relation to their efforts. The course received very low scores when the students evaluated it. However, we could see quite clearly that they had developed an in-depth knowledge of the compared methods. The students also discussed issues such as reliability and validity of their research in a way that we had not seen in the course in its previous years. The whole experiment resulted in significant knowledge generation regarding how (and how not) to involve students in research.

Users' perception and reported effects of long-term access to in-vehicle traffic information services mediated through nomadic devices: Results from a large-scale inter-european field operational test
- 2015

Tidskriftsartikel (refereegranskat)abstract
- ICT-mediated traffic information has been argued to contribute to a more sustainable transport system through affecting drivers. Nevertheless, long-term effects of travellers having access to nomadic in-vehicle systems for traveller information are not well known. This study presents the results from a multi-national large-scale field operational test (FOT). The results show that the users in general were positive to the tested systems and that there were several effects on their driving behaviour but in many cases the effects were limited. Moreover the effects varied between system types. Positive effects were related to comfort, as well as individual and system efficiency. One could also notice that perceived effects were not as high as the participants had expected, leading to some disappointment. Most of the times this was due to the tested systems functioning in a less than optimal way.

Electric bicycle adoption – drivers and barriers from a user perspective
- 2016
-
Ingår i: proceedings of WeBikeC 2016: Workshop On Electric Bicycle Commuting, 9-10 June 2016, Ghent, Belgium.
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Recent technological advances has led electric bicycles to represent novel opportunities to replace car journeys. However, despite the potential for societal gains, there is relatively little research that studies why potential users either choose to ride an electric bicycle, or not. Accordingly, this study investigates drivers and barriers of using an electric bicycle for everyday trips through a case study in western Sweden.
