Konferensbidrag (populärvet., debatt m.m.)abstract
- There has been a growing recognition among noise researchers that natural elements and natural areas of the built environment have potentials to reduce annoyance due to traffic noise. It has been suggested that presence of vegetation (e.g., trees, bushes, grass, flowers) contributes to an aesthetically pleasing environment, which influence overall residential satisfaction and people?s perception of the noise. Other expected benefits of natural elements/areas are prevention or modification of adverse effects of work-, personal-, or environmental stress (e.g., noise) through restoration processes. Within the large TVANE-project, the present study examined the effect of green areas (park or similar at walking distance) on noise responses in residential settings (n=468) exposed to road traffic noise (LAeq,24h 45 to 65 dB). A binary multiple logistic regression analysis, with sound exposure as the prime variable assumed to predict general noise annoyance at home, indicated that presence of green areas, a closer distance to it from the subject?s home, and perceived green-area characteristics (good sound environment, high attractiveness and potentials for recreational activities) significantly lowered noise annoyance. The results suggest that the exposure-response relationship between noise and annoyance is influenced by access to nearby green areas provided that they have good environmental quality, particularly regarding the perceived sound environment

- Eighty-five volunteer drivers, 65-85 years old, without cognitive impairments impacting on their driving were examined, in order to investigate driving errors characteristic for older drivers. In addition, any relationships between cognitive off-road and on-road tests results, the latter being the gold standard, were identified. Performance measurements included Trail Making Test (TMT), Nordic Stroke Driver Screening Assessment (NorSDSA), Useful Field of View (UFOV), self-rating driving performance and the two on-road protocols P-Drive and ROA. Some of the older drivers displayed questionable driving behaviour. In total, 21% of the participants failed the on-road assessment. Some of the specific errors were more serious than others. The most common driving errors embraced speed: exceeding the speed limit or not controlling the speed. Correlations with the P-Drive protocol were established for NorSDSA total score (weak), UFOV subtest 2 (weak), and UFOV subtest 3 (moderate). Correlations with the ROA protocol were established for UFOV subtest 2 (weak) and UFOV subtest 3 (weak). P-Drive and self ratings correlated weakly, whereas no correlation between self ratings and the ROA protocol was found. The results suggest that specific problems or errors seen in an older persons driving can actually be "normal driving behaviours".

- The frequency of occupational accidents in Swedish farming is high. An intervention methodology aimed at influencing safety attitudes and behaviour was previously tested. The aims of the present study were to evaluate long‐term effects of the intervention and to assess these results in relation to a randomly selected comparison group.The intervention was based on regular group discussions, focusing on dialogue and reflection in networks for social support. Eighty‐eight farmers and farm workers, divided into nine groups, participated. Each group gathered on seven occasions during one year, assisted by a process consultant, supporting safety communication and the change process. A questionnaire was used to evaluate the effects. The long‐term results of the intervention showed that safety activity increased significantly and risk acceptance (fearlessness) and work stress decreased. Measurements were made at T1, T2 and T3, i.e., pre‐, post‐ and long‐term, in the intervention group and at T1 and T3 in the comparison group.The results of the present study showed a long‐term effect of the intervention on safety activity and risk acceptance (fearlessness) in relation to the comparison group. However, the comparison group also showed a decline in work stress, which indicates that the stress reduction may have had other causes than the intervention.

Tidskriftsartikel (refereegranskat)abstract
- Digital infrastructures enable delivery of information services in functional areas such as health, payment, and transportation by providing a sociotechnical foundation for partnership governance, resource reuse, and system integration. To effectively serve emerging possibilities and changing purposes, however, a key question concerns how an infrastructure can be extended to cater for future services in its functional area. In this paper, we approach such digital infrastructure growth as a challenge of aligning new partners whose digital capabilities spur innovative services that attract more users. We advance an initial typology that covers four growth tactics (i.e., adding services, inventing processes, opening identifiers, and providing interfaces) with the potential to set extension of infrastructures in motion. We then explore the proposed typology by investigating the ways in which its particular tactics successfully extended the scope of a digital infrastructure for public transportation in Stockholm, Sweden. Our insights invite IS scholars to engage more deeply in the development of growth tactics that achieve infrastructure extensions necessary for improving the durability of service delivery.

Non-collision incidents on buses due to acceleration and braking manoeuvres leading to falling events among standing passengers
- 2019
-
Ingår i: Journal of Transport & Health. - : Elsevier BV. - 2214-1405 .- 2214-1413. ; 14:September

Tidskriftsartikel (refereegranskat)abstract
- Background: On public transport buses, standing passengers are subject to acceleration and braking driver manoeuvres which may lead to a falling event. Purpose and procedures: This study investigates the characteristics of such events connected to driver manoeuvres (i.e., acceleration or braking), passenger conditions (i.e., boarding, travelling, alighting), and injury severity. The data for analyses comprise three and a half years (2015-2018). All passengers were standing at the time of the fall event and were treated at hospital emergency departments (ED) after the falling event. Findings: The results highlight aspects which may need further attention. For example, the involvement of females is not only high for the 65 + age group, this is also the case for younger age groups which indicates that acceleration/deceleration threshold values for sustaining balance may differ by gender. Furthermore, driver manoeuvres and passenger conditions are important characteristics impacting the mechanisms of falling differently. In acceleration manoeuvres, older passengers (aged 65 +) are most often involved in a fall inmediately after boarding, whereas falls during braking manoeuvres are most common while travelling, and mostly involving the 25-64 years-old age group. Conclusions: These findings may indicate that acceleration and braking manoeuvres should be studied separately. It is worth noting that driving style might influence the risk of losing balance for standing passengers, and shortening the time to get seated can be beneficial for reducing the risk of falling, especially for the elderly users after boarding the bus.

Self-Perception and the Relation to Actual Driving Abilities for Individuals With Visual Field Loss
- 2022
-
Ingår i: Frontiers in Human Neuroscience. - : Frontiers Media SA. - 1662-5161. ; 16
-
Tidskriftsartikel (refereegranskat)abstract
- BackgroundIn Sweden, individuals with visual field loss (VFL) have their driving license withdrawn. The literature clearly indicates that individuals with VFL are unsafe drivers on a group level. However, many drivers with VFL can be safe on an individual level. The literature also suggests that self-perception, beliefs, and insights of one's own capabilities are related to driving performance. This study had three aims: (1) To investigate self-perceived driving capability ratings for individuals with VFL; (2) to compare these ratings between groups with different medical conditions associated with VFL (stroke, glaucoma, and diabetes); and (3) to relate the self-perception ratings to actual driving performance in an advanced driving simulator. MethodsParticipants comprised 723 individuals whose driver's license had been withdrawn because of VFL and 92 normally sighted elderly individuals. All participants completed a background survey, rated difficulties with different traffic situations, rated their strengths and weaknesses as drivers, and rated aspects that were important for causing traffic accidents. Of the VFL group participants, 264 also completed a simulator-based driving test that they knew could lead to renewal of their driving license. VFL participants and normally sighted was at the same age when they completed the simulator driving test. ResultsOverall, individuals with VFL rated their capabilities as high on all instruments and scales used, even higher than the elderly normally sighted control group. The only VFL etiology group that rated lower than other groups was the diabetes group. Safety orientation and internal control orientation values were best at discriminating between VFL participants in terms of self-perception of driving performance. Participants categorized as "high" in terms of safety skills and internal control were more modest in their ratings. Finally, participants who passed the simulated driving test did not differ from those who failed, in any of the self-perception measures. ConclusionSelf-perception ratings among individuals with VFL were higher than those of normally sighted elderly individuals. Self-assessed skills did not predict driving performance. Groups with different VFL etiologies rated similarly. Self-ratings of driving abilities cannot be used to assess actual driving performance. Actual driving tests (on road or in the simulator) are necessary to discriminate between safe and unsafe drivers with VFL.

Tidskriftsartikel (refereegranskat)abstract
- Ongoing urban exploitation is increasing pressure to transform urban green spaces, while there is increasing awareness that greenery provides a range of important benefits to city residents. In efforts to help resolve associated problems we have developed a framework for integrated assessments of ecosystem service (ES) benefits and values provided by urban greenery, based on the ecosystem service cascade model. The aim is to provide a method for assessing the contribution to, and valuing, multiple ES provided by urban greenery that can be readily applied in routine planning processes. The framework is unique as it recognizes that an urban greenery comprises several components and functions that can contribute to multiple ecosystem services in one or more ways via different functional traits (e.g. foliage characteristics) for which readily measured indicators have been identified. The framework consists of five steps including compilation of an inventory of indicator; application of effectivity factors to rate indicators' effectiveness; estimation of effects; estimation of benefits for each ES; estimation of the total ES value of the ecosystem. The framework was applied to assess ecosystem services provided by trees, shrubs, herbs, birds, and bees, in green areas spanning an urban gradient in Gothenburg, Sweden. Estimates of perceived values of ecosystem services were obtained from interviews with the public and workshop activities with civil servants. The framework is systematic and transparent at all stages and appears to have potential utility in the existing spatial planning processes.

Tidskriftsartikel (refereegranskat)abstract
- © 2015 The Authors. The urban environment is a complex structure with interlinked social, ecological and technical structures. Global warming is expected to have a broad variety of impacts, which will add to the complexity. Climate changes will force adaptation, to reduce climate-related risks. Adaptation measures can address one aspect at the time, or aim for a holistic approach to avoid maladaptation. This paper presents a systematic, integrated approach for assessing alternatives for reducing the risks of heat waves, flooding and air pollution in urban settings, with the aim of reducing the risk of maladaptation. The study includes strategies covering different spatial scales, and both the current climate situation and the climate predicted under climate change scenarios. The adaptation strategies investigated included increasing vegetation; selecting density, height and colour of buildings; and retreat or resist (defend) against sea-level rise. Their effectiveness was assessed with regard to not only flooding, heat stress and air quality but also with regard to resource use, emissions to air (incl. GHG), soil and water, and people's perceptions and vulnerability. The effectiveness of the strategies were ranked on a common scale (from -3 to 3) in an integrated assessment. Integrated assessments are recommended, as they help identify the most sustainable solutions, but to reduce the risk of maladaptation they require experts from a variety of disciplines. The most generally applicable recommendation, derived from the integrated assessment here, taking into account both expertise from different municipal departments, literature surveys, life cycle assessments and publics perceptions, is to increase the urban greenery, as it contributes to several positive aspects such as heat stress mitigation, air quality improvement, effective storm-water and flood-risk management, and it has several positive social impacts. The most favourable alternative was compact, mid-rise, light coloured building design with large parks/green areas and trees near buildings.
