Autonoma elektrifierade bussar : sammanlagda erfarenheter med fokus på användare
- 2023
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Ride the future är en mobilitetslösning med tre elektrifierade autonoma bussar som trafikerar en 4,2 km lång slinga vid Linköpings Universitet och Vallastaden. Ett av målen för Ride the future är att visa hur en autonom elektrifierad buss kan vara en del av mobiliteten i den moderna förtätade staden. För att nå upp till det målet finns ett behov av att summera resultat från forskningsprojekt som har studerat användningen av de autonoma bussarna. Syftet med den här rapporten är att sammanfatta och diskutera dessa resultat med utgångspunkt i användares behov och erfarenheter.I sammanfattningen ingår aspekter kring fordon och drift, infrastruktur och användarnas uppfattning kring attraktivitet, tillgänglighet, bekvämlighet och inkludering.En sammanställning av genomförda användarstudier visar att majoriteten av de resenärer som testat bussarna är positiva till resandet, men att det krävs insatser för att attrahera bilister. Vidare behövs ett ökat fokus på utvecklingen av hur fordonen ska kunna kommunicera med resenärer i bussen, men även med de som interagerar med bussen utanför (fotgängare, cyklister och andra fordonsförare). Föraren är viktig sett utifrån den situation vi har idag med en till viss del omogen teknik. Förarna stöttar såväl bussen som resenärerna och då i synnerhet barn, äldre och personer med funktionsnedsättning. För att mobilitetstjänsten ska vara tillgänglig för alla passagerare behövs ändå utveckling och förbättring av både fysisk infrastruktur och digitala lösningar.Projektet Ride the futures parter avser att fortsätta med den gemensamma ambitionen att testa och bidra till utvecklingen av de lösningar som krävs för ett framtida hållbart mobilitetssystem inom både den förtätade staden och landsbygden. Frågeställningar som är nödvändiga att arbeta vidare med är både tekniska, mellanmänskliga samt affärsmässiga.

- OBJECTIVE: Compare the long-term effects of two different individualised physical activity interventions in hip or knee osteoarthritis patients.DESIGN: Randomised, assessor-blinded, controlled trial.SETTING: Primary care.SUBJECTS: Patients with clinically verified hip or knee osteoarthritis, <150 min/week with moderate or vigorous physical activity, aged 40-74.INTERVENTION: The advice group (n = 69) received a 1-h information and goalsetting session for individualised physical activity. The prescription group (n = 72) received information, goalsetting, individualised written prescription, self-monitoring, and four follow-ups.MAIN MEASURES: Physical activity, physical function, pain and quality of life at baseline, 6, 12 and 24 months.RESULTS: There were only minor differences in outcomes between the two groups. For self-reported physical activity, the advice group had improved from a mean of 102 (95% CI 74-130) minutes/week at baseline to 214 (95% CI 183-245) minutes/week at 24 months, while the prescription group had improved from 130 (95% CI 103-157) to 176 (95% CI 145-207) minutes/week (p = 0.01 between groups). Number of steps/day decreased by -514 (95% CI -567-462) steps from baseline to 24 months in the advice group, and the decrease in the prescription group was -852 (95% CI -900-804) steps (p = 0.415 between groups). Pain (HOOS/KOOS) in the advice group had improved by 7.9 points (95% CI 7.5-8.2) and in the prescription group by 14.7 points (95% CI 14.3-15.1) from baseline to 24 months (p = 0.024 between groups).CONCLUSIONS: There is no evidence that individualised physical activity on prescription differs from individualised advice in improving long-term effects in patients with hip or knee osteoarthritis.

- OBJECTIVE: To compare the responsiveness of two unilateral lower-limb performance-based tests, the one-leg rise test and the maximal step-up test, with the bilateral 30-second chair-stand test and the self-reported measure of physical function (HOOS/KOOS). Specific aims were to evaluate responsiveness, floor/ceiling effect and association between the instruments.METHOD: Data was included from 111 participants, mean age 61.3 years (8.3), with clinically verified hip or knee osteoarthritis, who reported less than 150 minutes/week of moderate or vigorous intensity physical activity. Responsiveness, how well the instruments captured improvements, was measured as Cohen's standardised mean difference for effect size, and was assessed from baseline to 12 months following a physical activity intervention. Other assessments were floor and ceiling effects, and correlations between tests.RESULTS: The maximal step-up test had an effect size of 0.57 (95% CI 0.37, 0.77), the 30-second chair-stand 0.48 (95% CI 0.29, 0.68) and the one-leg rise test 0.12 (95% CI 0.60, 0.31). The one-leg rise test had a floor effect as 72% of the participants scored zero at baseline and 63% at 12 months. The correlation between performance-based tests and questionnaires was considered to be minor (r = 0.188 to 0.226) (p = 0.018 to 0.048).CONCLUSION: The unilateral maximal step-up test seems more responsive to change in physical function compared to the bilateral 30-second chair-stand test, although the tests did not differ statistically in effect size. The maximal step-up test provides specific information about each leg for the individual and allows for comparison between the legs.

- OBJECTIVE: To evaluate whether physical activity on prescription, comprising five sessions, was more effective in increasing physical activity than a one-hour advice session after six months.DESIGN: Randomized, assessor-blinded, controlled trial.SETTING: Primary care.SUBJECTS: Patients with clinically verified osteoarthritis of the hip or knee who undertook less than 150 minute/week of moderate physical activity, and were aged 40-74 years.INTERVENTIONS: The advice group (n = 69) received a one-hour session with individually tailored advice about physical activity. The physical activity on prescription group (n = 72) received individually tailored physical activity recommendations with written prescription, and four follow-ups during six months.MAIN MEASURES: Patients were assessed at baseline and six months: physical activity (accelerometer, questionnaires); fitness (six-minute walk test, 30-second chair-stand test, maximal step-up test, one-leg rise test); pain after walking (VAS); symptoms (HOOS/KOOS); and health-related quality of life (EQ-5D).RESULTS: One hundred four patients had knee osteoarthritis, 102 were women, and mean age was 60.3 ± 8.3 years. Pain after walking decreased significantly more in the prescription group, from VAS 31 ± 22 to 18 ± 23. There was no other between groups difference. Both groups increased self-reported activity minutes significantly, from 105 (95% CI 75-120) to 165 (95% CI 135-218) minute/week in the prescription group versus 75 (95% CI 75-105) to 150 (95% CI 120-225) in the advice group. Also symptoms and quality of life improved significantly in both groups.CONCLUSION: Individually tailored physical activity with written prescription and four follow-ups does not materially improve physical activity level more than advice about osteoarthritis and physical activity.TRIAL REGISTRATION: ClinicalTrials.gov (NCT02387034).

A Nationwide Study of Asthma and Allergy in Swedish Preschool Children : with Special Reference to Environment, Daycare, Prevalence, Co-ocurrence and Incidence
- 2010
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Aim: The aim of this project was to study the age and sex specific occurrence of atopic and non-atopic asthma and other atopic manifestations in a nationwide sample of Swedish pre-school children. Methods: All 70 allergen avoidance day-care centres (AADC) with 84 sections and 140 matched ordinary day-care centres with 440 sections in 62 municipalities across Sweden were sampled. In 2000 the staff at each section responded to a questionnaire on indoor and outdoor environment at the section. In 2002 parents of 5,886 children attending the AADCs and ODCs responded to a postal questionnaire regarding symptoms indicating prevalent asthma, allergic rhinitis, eczema, and food, furred pet and pollen allergy and other data in their children. In 2007, parents of 4255 children responded to an almost identical follow-up questionnaire. Results: The AADCs had far more strict rules than ODCs on furred pets and smoking at home and on perfume use, and the indoor environment was better, owing to better cleaning. The age specific asthma prevalence was curvilinear with a peak at age 3 of 11.4% among boys and 9.8% among girls. In addition the prevalence increased by municipality population density, a proxy for degree of urbanisation. There was a highly significant co-occurrence between all asthma-atopic manifestations, but there was no evidence of ordered sequence of manifestation onset. The asthma incidence was highly dependent on presence or absence of co-occurrence variables. Given the variable mix in the present study population, the annual asthma incidence ranged from 0.6% to 1.2%. Conclusions: AADCs had more strict rules and a better indoor environment than ODCs. The asthma prevalence was affected by age, sex and degree of urbanisation. There was close co-occurrence between all asthma and atopic manifestations but no evidence of ordered sequence of onsets. The annual asthma incidence was strongly dependent of co-occurrence conditions.

A nationwide study of asthma incidence and its determinants in preschool children during five years of follow up
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Background: Many studies on asthma prevalence have been published, but the number of studies on asthma incidence in preschool children is limited. A number of studies on asthma prevalence have been published, but there are few studies on asthma incidence in preschool children. In this project a nationwide sample of preschool children were followed with the aim to estimate 5-year asthma incidence and its determinants. Methods: Parents of 5886 children 1-6 years of age, sampled from day-care centres in 62 municipalities all over Sweden, responded in 2002 to a baseline postal questionnaire with questions regarding symptoms indicating possible asthma or atopic conditions, and a number of other variables. In 2007, 4255 of the parents responded to an almost identical questionnaire. Results: A large number of potential baseline determinants for 5-year asthma incidence were identified. Of these, food allergy, wheezing last 12 months, rhinitis, parental rhinitis, parental asthma, ever asthma, age, and eczema, on rank order of importance, remained significant in multivariate logistic regression analysis. The asthma incidence was highly dependent on presence or absence of these variables. Given the variable mix in the present study population, the incidence ranged from 2.9% in the oldest to 5.8% in the youngest children, corresponding to an annual asthma incidence of 0.6% to 1.2%. Conclusions: The incidence of asthma is highly dependent on the composition of the underlying population. However, an annual incidence in range a half to one percent in preschool children in the general population appears probable.

- While many studies on asthma prevalence have been published, the number of studies on asthma incidence in pre-school children is limited. In this project, a nationwide sample of pre-school children was followed with the aim of estimating cumulative 5-year asthma incidence and its determinants. Parents of 5,886 children 1-6 years of age, sampled from day-care centres in 62 municipalities all over Sweden, responded in 2002 to a baseline postal questionnaire with questions regarding symptoms indicating possible asthma or atopic conditions, and a number of other variables. In 2007, parents of 4,255 children responded to an almost identical follow-up questionnaire. Of these, the 3,715 children who were free from asthma at baseline constitute the study population for this report. A large number of potential baseline determinants for cumulative 5-year asthma incidence were identified. Of these, food allergy, rhinitis, incomplete asthma diagnosis criteria (wheezing last 12 months, and ever had asthma but no current symptoms), parental rhinitis, parental asthma, age, and eczema, in ranking order of importance, remained significant in multivariate logistic regression analysis. The asthma incidence rate was highly dependent on presence or absence of these variables, the average annual rate ranging from 2/1,000/year in 6-year-olds with no determinants to154/1,000/year in 1-year-olds with all determinants, corresponding to 11/1,000/year based on the whole study population.

Tidskriftsartikel (refereegranskat)abstract
- Sweden has had specialized 'allergen avoidance daycare centers' (AADC) since 1979. The aim was to compare AADC with ordinary daycare centers (ODC). Through contacts with municipalities and hospitals, 72 AADC were identified. For each AADC, the two nearest ODCs served as controls. A questionnaire was sent to the local directors of the 216 daycare centers (531 sections), 83% responded. A total of 39% of the ODCs had ever had dampness/molds, 12% were near (<500 m) stables/farms, 23% were closer than 50 m to a heavy trafficked road, and 13% were exposed to wood smoke in winter. Only 11% of the AADCs had any child with furred pets at home, while 97% of the ODCs had children with furred pets. Bans on smoking at home and on perfumes were more common at the AADCs (P = 0.001). Fewer AADCs had PVC floors (OR = 0.53; P = 0.01), dampness/molds (OR = 0.55; P = 0.04), shelves (OR 3.03; P = 0.001), curtains (OR = 1.67; P = 0.047), and flowers (OR = 0.03; P < 0.001), while more had daily floor cleaning (OR = 19.9; P = 0.004), weekly wiping of furniture (OR = 11.0; P = 0.001), and washing of pillows/mattresses (OR = 2.74; P = 0.005) and curtains (OR = 9.07; P = 0.001). In conclusion, allergy avoidance daycare centers differ from other daycare centers, and may have better indoor environments. PRACTICAL IMPLICATIONS: There is a need to improve the indoor environments of daycare centers, including reduction of building dampness and molds. Allergen avoidance daycare centers (AADC) in Sweden differ from ordinary daycare centers in many respects, with fewer indoor and building factors related to dust, allergens and irritants. This shows that the indoor environments of daycare centers can be improved. Data suggest that AADC may have lower levels of pet allergens, and this is beneficial for children with pet allergy. The effects of these improvements on indoor exposures and health of the children need to be further evaluated.
