Pełny tekst źródłaWider bike facilities intuitively accommodate a greater number of cyclists in the same amount of time, but specific queue discharge characteristics associated with varying widths and/or types of bike facilities have not been thoroughly documented.
The focus of this research analyzed queues of cyclists at four signalized intersections in Portland, OR with varying widths on the approach and downstream intersection legs. A total of 2,820 cyclists within 630 groups of queued cyclists were observed at five different intersection layouts in Portland, Oregon. The layouts consisted of: a standard bike lane six feet wide connecting bicyclists to a standard bike lane six feet wide, a standard bike lane five feet wide connecting bicyclists to two standard bike lanes each five feet wide, a buffered bike lane 12 feet wide connecting bicyclists to a standard bike lane 6.5 feet wide, a bike box 21 feet wide connecting bicyclists to a buffered bike lane 10 feet wide, and a bike box 15 feet wide connecting bicyclists to two standard bike lanes each five feet wide.
For each configuration, the following aspects were analyzed: average headway per cyclist within each queue, the time required for queues to enter the intersection, the time required for queues to clear the intersection, the number of cyclists within queues, the width of the bicycle facilities, the approach grade, and the utilization of a bike box at the intersection approach if it was present.
The first major focus of the analysis reviewed the average headway values associated with each observed queue of cyclists. The queue size with the lowest mean of the average headway was for groups of seven cyclists with an average headway of approximately 0.8 seconds per cyclist. For queues larger than seven in size, the mean of the average headway remained relatively stable until queues of 12 in size and started to slightly increase toward approximately 1.0 seconds for queues larger than 12 cyclists. In addition, it appears that utilization of a bike box has a potential relationship with a reduced average headway as compared to queues that do not utilize a bike box. The associated reduction in the mean of the average headway was approximately 0.2 to 0.3 seconds per cyclist for queues of three or more in size.
The second major focus of the analysis reviewed the queue discharge rate associated with each observed queue of cyclists. The results appear to potentially indicate that wider bike facilities approaching an intersection, wider receiving bike facilities, or utilization of a bike box generally discharge queues of bicyclists into the intersection over a shorter amount of time as compared to facilities that are narrower or underutilized. The installation of a bike box at one of the study intersections increased the approach width from five to 15 feet and resulted in consistently lower average discharge times for all queue sizes, a reduction of greater than one second for queues of two cyclists to as much as about four seconds for queues of nine cyclists.
The third major focus of the analysis reviewed the intersection clearance time associated with each observed queue of cyclists. The results appear to potentially indicate that wider bike facilities approaching an intersection, wider receiving bike facilities, or utilization of a bike box generally clear queues of bicyclists through the intersection over a shorter amount of time as compared to facilities that are narrower or underutilized.

Pełny tekst źródłaOs planejadores de transporte precisam avaliar as condições de estresse dos usuários em infraestruturas cicloviárias, uma vez que situações de alto estresse podem desencorajar o uso deste modo de transporte sustentável. Poucas pesquisas têm questionado se existe alguma relação entre esses fatores ambientais e a resposta emocional em termos de medidas objetivas do estresse. O objetivo deste trabalho é explorar a incorporação de sensores inteligentes no planejamento e avaliação da infraestrutura cicloviária. Essa nova abordagem é focada na perspectiva de monitorar parâmetros intrínsecos ao usuário, como as emoções. Nesta perspectiva, os indicadores dos níveis de estresse são feitos a partir da medição direta de respostas fisiológicas em ciclistas ao longo do percurso. Essa abordagem aproveita os recursos tecnológicos para extrair informações dos usuários e permitir o uso dessas informações de forma integrada para melhorar a infraestrutura dos ciclistas. Os dados foram coletados por meio de sensores de estresse, de ruído e acelerômetros incorporados a um smartphone e GPS. Inicialmente é apresentado o problema e como o projeto e avaliação das ciclovias tem sido abordada na literatura. A abordagem proposta permitiu identificar as contribuições mais relevantes e as lacunas de pesquisa, tais como, a falta de pesquisas baseadas em critérios de objetivos e a falta de pesquisas que envolvam o desenho e a avaliação de cenários de infraestrutura compartilhados com veículos automotores. Em seguida foi proposto um método objetivo de avaliação de infraestruturas cicloviárias, combinando a avaliação ambiental com medições de aceleração vertical, a fim de melhorar a coleta de dados e outros procedimentos necessários para avaliar os principais componentes das infraestruturas cicloviárias. Na sequência uma ferramenta para caracterizar o estresse de tráfego de ciclovias, denominada Level of Traffic Stress (LTS), foi validada com medidas fisiológicas no contexto urbano de uma cidade brasileira de porte médio. Observou-se que não há correlação e há pouca concordância entre esses parâmetros. Ressalta-se ainda que, mesmo ao incorporar informações de velocidade de tráfego à ferramenta LTS, não foi significativamente relacionado com estresse medido sob a perspectiva do ciclista. Por fim, foi investigada a influência do ruído, vibração, presencia ou ausência de ciclovias e período do dia no estresse experimentado pelos ciclistas. Uma análise dos valores de p e dos intervalos de confiança das razões de chances mostraram, com um nível de confiança de 95%, que apenas o período do dia influenciou o estresse. Neste caso, as chances de ter estresse aumentaram em 24% na hora pico da tarde em comparação com a hora pico da manhã. Este estudo mostrou a viabilidade da avaliação do estresse em ciclistas por meio de um método de medida objetiva além da rápida identificação dos níveis críticos de estresse.

Pełny tekst źródłaAlthough knowledge about the complex of problems with climate change is widespread, individuals often do not consider their own actions as contributors to climate change when they make their own choice of how to transport themselves, especially with the widespread use of cars. To reduce unnecessary car use, work is taking place at the public sector level in the city of Malmö. Through information, communication and campaigns, the city aims to raise the amount of pedestrians, cyclists and public transport users; this job can be summarized as: behavioral change. This job is part of the aim to make Malmö a more attractive and more sustainable city. The purpose of this study is to investigate how agents of change at the public sector level understand their profession and their professional role. This involves how they understand the boundaries in which they can operate, their understanding of competencies, how they understand success in their work, and how success can be and should be measured. The study took place through a qualitative study in the form of interviews where six agents of change at the Trafikmiljöenheten in Malmö Stad make up the empirical population for the study. The results show that the interviewed agents of change see opportunities and hindrances with working in the public sector. The advantages are that they feel a level of freedom, as they are not a company aiming to sell a product and that they feel they have the opportunity to affect how the work should go about through the opportunity to bring forward their own ideas. The disadvantages are the political arena that they are a part of, where the policies of the ruling politicians form the boundaries in which the agents of change can perform their work. There is tension between working with effects that only become evident in the long-term and the demands of showing short- term effects. The agents of change say that competencies of social and interpersonal character rather than technical and practical competencies are important for doing a good job. The interviewees outlined that the general attitude towards environmental questions and choice of transport modes has changed over the past 10-15 years which makes it easier for the agents of change to reach out with their messages.

Pełny tekst źródłaÄven om cyklister i många fall färdas på samma vägar som bilar, motorcyklar och mopeder är cyklar sällan utrustade med backspeglar. Istället förlitar sig de flesta cyklister på att se sig över axeln för att bedöma en trafiksituation, vilket kan vara både obekvämt och desorienterande, samtidigt som detta innebär att uppmärksamhet tas ifrån vägen framför cyklisten. Syftet med detta projekt var att undersöka och utvärdera befintliga backspegelprodukter för att försöka förstå varför de inte används i större utsträckning. Baserat på resultatet av denna undersökning var syftet dessutom att utveckla ett koncept på en ny produkt avsedd att öka cyklisters medvetenhet om vad som finns bakom dem i trafiken. Detta på ett sätt som innebar en förbättring av svagheterna med befintliga produkter. Genom tillämpning av användarcentrerade design- och undersökningsmetoder gjordes insikter som användes som inspiration för konceptutvecklingen. Dessa insikter översattes även till en kravspecifikation som användes för att utvärdera de olika koncepten. Utav sju koncept valdes ett för vidare utveckling, vilket inkluderade iterativ utveckling av en fungerande prototyp baserat på feedback från användare. Det resulterande konceptet var en cykelhjälm som via en inbyggd bakåtriktad kamera strömmade video till en app i användarens smartphone, i sin tur monterad på dennes cykelstyre.

Pełny tekst źródłaPostmodernism has been the focus of a growing number of academic studies, which research its characteristics, such as fragmentation, heterogeneity, juxtaposition of opposites and the disbelief in definite truths and universal explanations (COVA, 1996a). To define its strategies, postmodern researches should consider the existence of social microgroups, created freely by individuals, based on their emotional choices (MAFFESOLI, 2006). Also named neotribes, tribes, communities or postmodern groups (COVA, 1996a; MAFFESOLI, 2006), they bring together people through values such as locality, affinity, emotion and passion; have rituals and worship symbols, besides consuming products and services due to their capacity of creating social interactions - linking value (COVA, 1997). The main purpose of this work is to identify if and how the characteristics of the postmodern tribes apply to road cyclists, as to understand how their consumption works and verify the existence of linking values on its structure. The Walter Tuche Group, which gathers around 130 road cyclists in Rio de Janeiro, Brazil, was selected for this exploratory research. The subject’s choice aims at contributing to the marketing discipline academically and to the sport consumption business perspective, not only due to the importance of understanding consumers’ tribes on a postmodern view, but also due to the lack of studies on sport communities. The results suggest that the cycling group members possess habits peculiar to postmodern tribes and that their members consider the act of cycling as a mean to give purposes to their lives.

Pełny tekst źródłaTrafiken är en komplex miljö med många deltagare; diverse ny teknik gör anspråk på att underlätta denna komplexitet. Men, cyklister—en särskilt utsatt grupp av trafikanter—har hittills hamnat i skymundan för sådana utvecklingar. Vidare, aspekten av användbara gränssnitt för cyklister inom sådana uppkopplade och samverkande trafiksystem (C-ITS) har utforskats desto mindre. Det här examensarbetet inom Teknisk design presenterar fem multimodala kollisionsvarningar avsedda för cyklister—framtida sådana i dessa C-ITS—genom en ny och bimodal användning av benledande hörlurar via både ljud och vibrationer. Examensarbetet genomfördes i koppling till forskningsprojektet V2Cyclist, orkestrerat av RISE Interactive, vars projektmål var att anpassa det trådlösa kommunikationsprotokollet V2X för cyklister via en fysisk prototyp i form av en cykelhjälm och parallellt utveckla ett tillhörande användargränssnitt. En viktig del av det teoretiska ramverket för det här examensarbetet grundar sig på multiple resource theory: uppgifter kan utföras mer effektivt i en annan modalitet än i en som redan är belastad med uppmärksamhet. Mänskliga faktorer och teori om vår uppfattning användes; bevis pekar på att människor har evolutionärt utvecklat en bias för hotande ljud som upplevs inkräkta på vårt närmsta personliga revir; etologiska rön visar på en koppling mellan lågfrekventa ljud och ‘storhet.’ Tekniker inom ljuddesign vanligtvis använda till mer artistiska ändamål, såsom syntes och mixning, användes här till godo för att utforska den nya och bimodala designrymden. Processen för arbetet grundade sig i design thinking och bestod av fyra faser: kontextfördjupning, idégenerering, konceptutveckling, och utvärdering. En ny och tidigare outforskad designrymd beståendes av en bimodal, ljudtaktil användning av benledande hörlurar divergerades och konvergerades. Ett initialt utforskande angreppssätt gav upphov till en bred mängd av idéer. Ett senare renodlande angreppssätt gick, dock, inte hela vägen till endast en optimal lösning, då vidare utvärdering krävs men också på grund av okända teknologiska begränsningar. Dessutom, givet cyklisters stora mångfald, kan det möjligtvis följa att det inte finns någon enskild design av den optimala kollisionsvarningen. Ett spann på fem olika lösningar presenteras därmed. Fem koncept för multimodala kollisionsvarningar presenteras där varje variant uttrycker fara och kritiskhet på olika sätt. Vissa är statiska i typ, medan andra verkar mer kontinuerligt och dynamiskt. Det antogs att kollisionsvarningar sker sällan. Olika designtekniker och motiveringar har använts, ibland i kombination med varandra, för att skapa kollisionsvarningar vars avsikter omedelbart förstås: normer inom design och kultur gällande ljud; uttalad kommunikation i form av tal; anspråk på människors biologiska intuition via hotfulla och djurliknande klangfärger; dynamisk och procedurellt genererad feedback; multimodal effektfullhet; korsmodal känsla av grova texturer; size-sound symbolism för att antyda ‘storhet;’ samt de naturligt aktiverande egenskaperna hos looming sounds.

Pełny tekst źródłaSyfte Syftet med denna studie var att skapa en metod för att åstadkomma skillnader i muskelglykogen samt observera den akuta effekten av träning med låga muskelglykogennivåer på metabola och fysiologiska parametrar. Metod Vid två tillfällen fick tio vältränade mountainbike- eller landsvägscyklister ((medel±SD) ålder, längd, kroppsvikt, VO2max och VO2max·kg-1 var 28±5 years, 74,7±6,3 kg, 183±6 cm, 4876±332 mL min-1, 64,4±2,8 mL·kg min-1) genomföra ett träningspass i syfte att tömma muskelglykogendepåerna följt av en natts vila och sedan ett andra träningspass. Studien följde ett randomiserat crossover-upplägg och det ena försökstillfället genomfördes med en diet hög på kolhydrater och det andra tillfället med en diet utan kolhydrater (CHO). All testning genomfördes på en Monark 839E ergometer och muskelbiopsier togs före tömningspass, efter en natts vila före det andra träningspasset och tre timmar efter det andra träningspasset. Venösa blodprov togs i vila före biopsitagning för analys av plasma FFA och glukos. Resultat Koncentrationen av muskelglykogen före tömningspasset var 623±180 and 645±133 mmol·kg dw-1 vid försök utan respektive med CHO. Tömningspasset och 13 timmars vila resulterade i en signifikant minskning av muskelglykogen vid försök utan CHO (p<0.0001), och med CHO (p<0.01) till 166±71 och 478±111 mmol·kg dw-1. Nettominskningen av muskelglykogen vid tömningspasset utan CHO korrelerade positivt med glykogenkoncentration före tömning Efter genomförande av det andra träningspasset och tre timmars efterföljande vila var muskelglykogenmängden vid försöken utan CHO och med CHO 130±52 och477±97 mmol·kg dw-1. Vid träning med lågt muskelglykogen fanns det en kraftig ökning av fria fettsyror i blod vid vila och under arbete noterades en ökning skattning av Borg subjektivt skattad ansträngning (RPE) samt en sänkning av blodglukos. Slutsats Protokollet som användes i denna studie skapade framgångsrikt en minskning av muskelglykogen och träning med låga glykogennivåer kunde sammankopplas med flera fysiologiska parametrar som indikerar en möjlig sänkning av prestationsförmåga under uthållighetsarbete.

Pełny tekst źródłaENGLISH ABSTRACT: The purpose of this study was to determine the effect of plyometric exercise training on the aerobic and anaerobic capacities of well-trained cyclists. Twenty male competitive cyclists (age: 24 ± SD 5 years, height: 180 ± SD 6 cm and body mass: 77 ± SD 6 kg), including 12 mountain bikers and eight road cyclists were randomly divided into an experimental (n = 13) and a control group (n = 7). Testing included kinanthropometric measurements, vertical jump test, bench pull test, maximal aerobic capacity test, indoor 5-kilometer time trial (TT), anaerobic capacity test (30-second Wingate test) and an outdoor 4.4-kilometer time trial (field test). The plyometric training program had no statistically significant effect on the maximal aerobic capacity, anaerobic capacity, time trial performance (laboratory and field) and vertical jump performance of the experimental group. Selected outcome variables, i.e. VO2max, PPO and MP during the Wingate test and time to complete the laboratory TT, bordered on statistical significance. The experimental group significantly improved their upper body strength. There was also a strong correlation between the outdoor TT and upper body strength (r = 0.72). Although the plyometric training program did not significantly improve the performance of the cyclists, indications were that the experimental group improved their anaerobic power and upper body strength. One previous study in the literature suggested that the effects of a plyometric training program may only become evident a few weeks after completion of the program. It is therefore possible that the cyclists in this study would have experienced the benefits of plyometric training only later, i.e. closer to the competition season when the aim of their training program is to improve power and speed.
AFRIKAANSE OPSOMMING: Die doel van die studie was om te bepaal wat die effek van pliometriese oefeninge is op die aërobiese en anaërobiese vermoëns van goed ingeoefende fietsryers. Twintig kompeterende mans fietsryers, (ouderdom: 24 ± SD 5 jaar, lengte: 180 ± SD 6 cm en gewig: 77 ± SD 6 kg), was ewekansig ingedeel in of ‘n eksperimentele (n = 13) of ‘n kontrole groep (n = 7). Die groep sluit twaalf bergfietsryers en agt padfietsryers in. Kinantropometriese metings, vertikale spronghoogte, ‘n bolyf kragtoets (“bench pull test”), ‘n maksimale aërobiese uithouvermoë toets, ‘n binneshuise 5-kilometer tydtoets (TT), ‘n anaërobiese kapasiteit toets (30-sekonde Wingate toets) en ‘n buitemuurse 4.4-kilometer tydtoets (veldtoets) was voltooi gedurende die toetsperiode. Die pliometriese oefenprogram het geen statisties betenisvolle effek op maksimale aërobiese kapasiteit, anaërobiese kapasiteit, tydtoets prestasie (laboratorium en veld) of op vertikale spronghoogte van die eksperimentele groep gehad nie. Spesifieke uitkomsveranderlikes, soos VO2maks, piek en gemiddelde kraguitset gedurende die Wingate toets, en die tyd wat dit geneem het om die laboratorium tydtoets te voltooi, het gegrens aan ‘n statistiese betekenisvolle verbetering in die eksperimentele groep. Die eksperimentele groep het ‘n betekenisvolle verbetering getoon in hul bolyfkrag na die intervensie. Daar was ook ‘n sterk verband tussen die veld tydtoets en die bolyfkrag in die eksperimentele groep (r = 0.72). Hoewel die pliometriese oefenprogram nie die prestasie van die fietsryers betekenisvol verbeter het nie, het dit tekens van verbetering in die eksperimentele groep se anaërobiese en bolyfkrag getoon. ‘n Vorige studie het voorgestel dat ‘n pliometriese inoefeningsprogram slegs na ‘n paar weke na die intervensie ‘n effek sal toon in prestasie. Daarom is dit moontlik dat die fietsryers in die studie die voordele van pliometriese oefeninge eers later ervaar het, nader aan die kompetisiefase wanneer die doel van die oefenprogram is om spoed en krag te verbeter.

Pełny tekst źródłaElectric bicycles (e-bikes) are a relatively new form of transport. The aim of this dissertation is to investigate their effects on road safety. In 2012, at the beginning of this dissertation project, knowledge of e-bikes in general and their impact on road safety in particular was relatively scarce. As a starting point of this work, the influence of e-bikes on road safety was investigated compared relative to the road safety of conventional bicycles. Additionally, the influence of the age of the rider on safety is considered as a supplementary factor. Special attention is paid to the impact of the infrastructure utilised by riders and its characteristics. This cumulative dissertation consists of four research articles, labelled Paper I to IV accordingly. Papers I to IV have been published in peer reviewed journals. The synopsis provides an overview of previous research as well as a theoretical framework of the safety of cyclists and e-bike riders. Speed, and its perception through other road users (measured with experiments to gap acceptance and time to arrival (TTA) estimates) are considered as relevant factors for road safety. In Chapter 4, the research objectives are presented in detail. The methodology is clarified in Chapter 5, and in Chapter 6 and 7 the results are summarised and discussed. The implications of the results are considered in Chapter 8. In Paper I, the differences in speed between bicycles, pedelecs (pedal electric cycle, motor assistance up to 25 km/h) and S-pedelecs (pedal electric cycle, motor assistance up to 45 km/h) were investigated. Additionally the influence of infrastructure type, road gradient and the age of the rider were taken into account. Paper II is concerned with the influence of different conflict partners in crashes, and the utilisation of infrastructure on the safety of cyclists. For this purpose, safety critical events (SCE) involving cyclists were examined, with a special focus on the differences between younger, middle aged, and older cyclists. Papers III and IV focus on the perception of speed of e-bike and bicycle riders through other road users and its implications for road safety. Paper III specifically deals with the gap acceptance of car drivers at intersections in the presence of cyclists and e-bike riders with different speeds and under varying conditions (e.g. at intersections with different road gradients). Paper IV looks at drivers TTA estimates of approaching bicycles and e-bikes in combination with other influencing factors (e.g. speed, cyclist age)

Aims of this thesis: the research reported in this thesis consists of a literature review and two research parts. In the first research part, a descriptive cross-sectional survey was conducted, to investigate 1) the epidemiology and 2) the nature of LBP in cyclists, and 3) possible risk factors associated with LBP in cyclists. In the second research part, a case control study was conducted, to investigate the association between LBP in cyclists and 1) flexibility and 2) anthropometric measurements, and 3) bicycle set-up parameters.
