E-scooters are quite popular among young people in big cities. Their use seems to be a well-studied phenomenon. This study concentrates on the risky behaviour of e-scooter riders and on e-scooter riders' and non-riders' attitudes towards risky e-scooter riding. The goals were to describe these attitudes and to describe the most common types of risky e-scooter behaviours in five participating countries. An online questionnaire was developed and distributed in Australia, Belgium, the Czech Republic, Sweden, and Norway from June to September 2020. Respondents were recruited through sponsored Facebook ads and participant sharing (snowball sampling). The riders in the countries considered in this study tend to perceive e-scooters as being quite safe. The majority of them even think e-scooters pose no danger to other road users. On the other hand, the non-riders believe riding an e-scooter is rather unsafe, with the exception of Belgium, where the respondents tend to think that it is very unsafe. When risky behaviour is considered, the non-riders tend to report more risky behaviour than e-scooter riders, even though fact-based observable behaviour, e.g. helmet use, should in principle be the same across both groups. In addition, as the existing literature shows, evidence suggests that young riders and male riders engage in more risky riding behaviours in comparison to older and female riders. This phenomenon should be addressed by effective preventive programmers and campaigns. The data shows that a greater frequency of riding predicted more risky riding behaviours. Although there are some differences between the samples under study, these findings can inspire police officers to promote e-scooter safety behaviour. [ABSTRACT FROM AUTHOR]

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.

Design representations are important tools for designers in the design process. To help designers choose the appropriate representation, taxonomies have been proposed based on type, degree of fidelity, and when to use them. However, Design representations may also play an important role in designers' communication with users and enabling users as co-designers. Therefore, new taxonomies, focusing on design representations' potential mediating roles in collaborative design processes with users, have been developed. The purpose of this interview study, with twelve designers within Swedish industry, was thus to investigate how designers use design representations in communication with users in the design process. The study indicates that the designers mainly interacted with users in order for them to answer specific design questions or to evaluate design solutions. If design representations' value for facilitating communication and collaboration with users should be emphasized, we need to shift from teaching mainly taxonomies related to fidelity levels or when to use them in the design process, and rather educate future designers about design representations inherent potential to mediate and enhance the dialogue with users.

Bicycle infrastructure is in most cities a fairly recent addition and something that has, in many cases, been squeezed in where space has been available. Consequently, the properties of bike lanes differ a lot between different locations. An observation that is easy to make is that when bike lanes are wide, smooth, and straight, the variation in cyclists’ behaviour is low. When on the other hand there are lanes that disappear, that takes long detours, or are blocked for various reasons, cyclists start to act in a way that from an outsider perspective may look random or at least difficult to predict. This paper reports on a study where 17 cyclists have filmed their daily commute with GPS equipped action cameras. They then observed their film together with a researcher and explained how they perceive the route and how they make their choices in traffic. Based on the results of the study we present a tentative model of how cyclist behaviour can be predicted that can be used as a design tool when designing bicycle infrastructure or making changes to existing infrastructure. The model suggests that cyclist behaviour is affected by two sets of factors; physical factors that can be viewed as unintentional nudges associated with the environment, and subjective factors that are based on rational decisions by the individual cyclist.

Objective: Crashes between cars and cyclists at urban intersections are common, and their consequences are often severe. Typical causes for this type of crashes included the excessive speed of the cyclist as well as car drivers failing to see the cyclist. Measures that decrease the cyclists' speed may lead to safer car-cyclist interactions. This study aimed to investigate the extent to which cyclists may approach intersections at a lower speed when nudged to do so.Methods: Visual flat-stripe nudges were placed on bicycle lanes in the proximity of uncontrolled intersections (with a history of car-cyclist crashes) in two locations in Gothenburg, Sweden. This specific nudge was the one obtaining the best results from a previous study that tested different nudges in controlled experiments. Video data from the intersections were recorded with a site-based video recording system both before (baseline), and after (treatment), the nudge was installed. The video data was processed to extract trajectory and speed for cyclists. The baseline and treatment periods were equivalent in terms of day of the week, light, and weather conditions. Furthermore, two treatment periods were recorded to capture the effect of the nudge over time in one of the locations.Results: Leisure cyclists showed lower speeds in treatment than in baseline for both locations. Commuters were less affected by the nudge than leisure cyclists. This study shows that visual nudges to decrease cyclist speed at intersections are hard to evaluate in the wild because of the many confounders. We also found that the effect of visual nudges may be smaller than the effect of environmental factors such as wind and demographics, making their evaluation even harder.Conclusions: The observed effect of speed might not be very high, but the advantage both in terms of cyclist acceptance and monetary cost makes an investment in the measure very low risk. This study informs policymakers and road authorities that want to promote countermeasures to intersection crashes and improve the safety of cyclists at urban intersections.

The main objective of WP5 is to run a set of field trials with naïve users (i.e. not experts involved in the development of the measures) for all nudging and coaching measures developed in WP2-4. Field trials with naïve users are necessary in order to validate the estimated effectiveness of each measure. The field trials were set up in as realistic settings as possible, given the possibilities to implement/distribute each measure. This deliverable gives a short description of the field trial setup for each measure, and then reports the effects of the nudge on road user behaviour.

Bicycle riders are over represented in fatal traffic accidents in Europe, and the trend is still on the rise (European Commission, 2018). While most cycling accidents are defined as single accidents, the outcome of an accident where a car or other heavy vehicle is involved is naturally much more severe. A Swedish study found that eight of ten car-bicycle accidents happen in intersection scenarios (Isaksson-Hellman & Werneke, 2017). If cyclists, as well as car drivers, adapt their speed before intersections everyone has more time to spot each other and to take evasive action, which should lead to a decrease in accidents. Authorities around the world are putting up physical obstructions such as rumble stripes to make cyclists slow down, but is this the right way to go? Previous studies have found smooth surfaces to be a very important factor for cycling comfort, and vibrations to be highly disliked (Ayachi et al., 2015; Bíl et al., 2015; Stinson and Bhat, 2005; Torbic et al., 2003). The core of the MeBeSafe project is to investigate whether nudging, i.e. non-forcing measurements without demands on conscious interpretation, can be used to influence traffic behaviour and suggest how these nudges should be designed. In the project, both visual and haptic nudges have been developed and tested. This paper reports on an experimental study with 16 participants, 19-75 years of age, that was carried out with six different haptic nudges. The nudges consisted of modified surface softness and roughness as well as dimensional modifications. Results indicate that most haptic nudges have very little effect on speed and those with larger effect are generally disliked. This suggests that building physical obstructions for cyclists may not be the correct way forward, although results from cycling workshops performed in the project suggests that haptic nudges might be a good choice if one wants to nudge cyclist to change trajectory. If one wants to affect bicyclists’ speed, visual nudges are likely to be a more constructive route for cities to take.

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.

BICYCLE sharing programs - 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, Sweden (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. [ABSTRACT FROM AUTHOR]

HE - Abstract
Using bicycles on an ‘as-needed’ basis, usually for a small rental fee and without the externalities and obligations linked to bicycle ownership, is what makes public bicycles a societally affordable medium to enhance the transition to a more sustainable urban transport paradigm. However, despite its distinctive character in terms of its potential to be a mechanism transforming in some degree urban mobility to a shared responsibility regime, bike-sharing still faces some of the same safety concerns associated with ordinary bicycle ridership. The most common problem for cyclists’ wellbeing is that the traffic system is designed predominately from a car-user perspective. Even the cities that have recently implemented public bicycle programmes, and therefore showed some extra care to provide fitting urban conditions for them, have not yet achieved to fully eclipse car-orientation as the prime cornerstone of their development norms. This means that transport systems worldwide do not necessarily take fully into account the main characteristics of cyclists reflecting safety themes: a cyclist is vulnerable (in a crash), flexible (in behaviour), instable (may fall off the bike), inconspicuous (difficult to see), has differing abilities (due to a wide range of the population), is conscious of effort (i.e., highly motivated to minimize energy expenditure), and sometimes seen as intruders in the traffic systems, rather than as an integral part. This work refers to the results of a research scheme that meant to examine road users’ attitudes directly reflecting public acceptability towards two bike-sharing schemes in Drama (Greece, 50.000 residents) and Gothenburg (Sweden, 500.000 residents). Although safety was not the principal initiative for doing this dual study, one key conclusion was that many people could not embrace bike-sharing due to their perceptions that bicycle represents in general an unsafe travel mode and that their cities provide only limited road safety for cyclists.
