Discourse about the real-world effects of automated vehicles has intensified over the last decade, but few observational studies have been made examining their integration in real traffic. This research is based on the dataset prepared by Beauchamp et al. in [1] where video footage from two pilot projects involving automated shuttles in Montreal and Candiac in 2019 was analyzed to compute safety indicators from road user trajectories. The study showed that automated shuttles have safer interactions with other road users compared to human drivers following the same trajectories. Yet, this may not be the only characteristic of automated shuttles. These vehicles are notoriously slow, 10 to 15 km/h slower than human-driven cars in city traffic [1], which on city streets is bound to influence other road users, in particular following cars. lt is therefore hypothesized that automated shuttles may have a traflic calming effect, slowing other motorized vehicles [2]. Slower speed and the predictability of automated shuttles, obeying the rules of the road and yielding more willingly to vulnerable road users (pedestrians and cyclists) may also have an impact on these users' behavior [3]: for example, cyclists may pass the shuttle, pedestrians may cross outside of crosswalks. The present study aims to explore the potential effects of automated shuttles, with their slower spceds and more predictable behavior, on the behavior of other road users. [from Introduction]

I dagens planeringsprocesser inkluderas medborgare huvudsakligen genom samrådsprocessen. Detta innebär två huvudsakliga problem: Det första problemet är att medborgares kunskap inkluderas först efter att problemen för en planeringsprocess är fastställda. Det andra problemet är att det endast är de medborgare som närvarar vid samrådet som möjlighet att representera sin kunskap och sina åsikter. Uppsatsens syftar därför till att undersöka om och eventuellt hur olika kunskapsunderlag påverkar hur problem formuleras i stadsplaneringsprocesser. Vidare syftar uppsatsen till att undersöka hur inkluderingen av olika former av kunskap kan påverka vilka åtgärder som prioriteras inom stadsplaneringsprocesser.Det huvudsakliga metodvalet har varit en fallstudie av Malmabergsgatan i Västerås. Inom fallstudien har det sedan genomförts intervjuer med medborgare, tjänstepersoner och en fokusgrupp, samt en observationsstudie och en enkätundersökning. De resultat som framkom av vår undersökning visade att problem som formulerades av medborgare har en högre detaljnivå än de problem som tjänstepersonerna formulerade – detta trots att samma grundproblem definierades. Vidare har vi också kunna se att en inkludering av olika former av kunskap, i teorin, bör leda till mer resurseffektiva och acceptabla, från medborgarnas sida, åtgärdsförslag. / In city planning processes today citizens are mainly included through consultation processes. This implies two main problems: The first problem is that citizen’s knowledge only is included in city planning processes when problems already have been formulated. Secondly only citizens who attend the consultation process have the opportunity to represent their knowledge. This thesis objective is therefor to study if and possibly how different sources of knowledge affect how problems are formulated in city planning projects. Furthermore the objective is to study how inclusion of different forms of knowledge may affect which measures are prioritized in city planning processes.Our main method has been a case study of Malmabergsgatan in Västerås, Sweden. Within this case study we have exercised interviews with citizens, communal office workers and a focus group. We have also exercised one observational study and one survey study. Our results showed that problems formulated by citizens contain a higher degree of detail than problems formulated by communal office workers – even though they defined the same basic problem. We have also seen results showing that inclusion of different forms of knowledge, in theory, should lead to measures in city planning processes that are more acceptable, from a citizen’s perspective, and more resource efficient.

Travel times, operating speeds, and service reliability influence costs and service attractiveness. This paper outlines an approach to quantify how these metrics change after a modification of roadway design or transit routes using archived transit data. The Tri-County Metropolitan Transportation District of Oregon (TriMet), Portland's public transportation provider, archives automatic vehicle location (AVL) data for all buses as part of their bus dispatch system (BDS). This research combines three types of AVL data (stop event, stop disturbance, and high-resolution) to create a detailed account of transit behavior; this probe data gives insights into the behavior of transit as well as general traffic. The methodology also includes an updated approach for confidence intervals estimates that more accurately represent of range of speed and travel time percentile estimates. This methodology is applied to three test cases using a month of AVL data collected before and after the implementation of each roadway change. The results of the test cases highlight the broad applicability for this approach to before-and-after studies.

Chevron pavement markings have seen rising interest in the United States as a means to reduce speeds at high-speed locations and improve safety performance. In Atlanta, there are two freeway-to-freeway ramps where chevron markings are being used. A previous study analyzed before-and-after speed data at these ramps and found only a modest reduction on overall vehicle speeds. However, a cursory crash analysis indicated that the ramps had crash reductions of over 60%, suggesting that safety benefits exist even though vehicle speeds are not significantly affected. This research aims to evaluate the safety performance of chevron markings on the two ramps in Atlanta, GA in order to quantify the potential impact of the treatment on safety and to understand the mechanism by which the treatment influences safety. This thesis begins with a literature review covering topics in human factors in safety, past uses of different types of pavement markings, and methods in using crash databases and police reports in accident studies. Next, the thesis presents an in-depth before and after analysis of crash data from crash databases and police reports provided by the Georgia Department of Transportation. And finally, the thesis concludes with a summary of findings and a discussion of further research needs. The results verified that there were 73% and 61% crash reductions in the two study ramps. Chevron markings appear to have benefitted all types of crashes and that they are possibly serving as a warning to drivers of potential upcoming hazards. Unavailability of a number of police reports and errors in crash databases were limitations to this study, and ultimately, new sites should be selected carefully and further studies need to be performed to better understand the treatment's benefits.

The use of wraps in the care of newborns and infants. The thesis deals with the use of wraps suitable for newborns and infants. Wraps are used particulary to calm down children. Because swaddling of a child imitates the strength and tightness of their mother's womb, children are mostly feeling calmly and safely. There are many wraps on the market, like blankets, classic lace-wraps, cocoons and wraps specially developed for restless and teary children. The goal of the thesis was to find out what knowledge have parents of children about swaddling, which wraps do they use and effect of swaddling on children. We have tried to verify the effects of swaddling in practice. In this thesis, we used a combination of qualitative and quantitative methods, interview techniques, and action research. The qualitative part of the research took the form of an unstructured interview. The sample for this interview was 33 mothers who had to answer open questions. The results of the interview were manually written to the printed record sheets. The interviewed responders were individually asked in their homes, in cafes and children's clubs. At first was completed the basic respondents information like their age, education level, place of residence and number of children and their age during their first pregnancy. Then we proceeded to talk about swaddling children to varienty types of wraps. We asked questions related to the type used wraps, swaddling style, usage time of wraps. We also asked about what for effect had swaddling on a child, whether the child calmed down, slept or remained teary. The collected personal information we processed statistically to help us to determine the answer to our hypothesis. Action research was applied on 4 children and one pair of twins in their home environment. Prior to that, their parents agreed with the research. We agreed that during the research will be present at least one parent. Parents received a record sheet on which they could write down when the child had trouble sleeping, or falling asleep and how much did the child cry. Based on their statements and notes we have devised a way to help the child to fall asleep or calm down. Parents got recommended specialized literature on swaddling, which they could later study. For swaddling we had the opportunity to use more types of wraps, according to the wish of parents, especially with best regards for the child, because each individual requires a specific type of swaddling and different wraps. Together with parents, we chose a wrap for the day or night and we wrapped the baby up and observed how it goes. Parents then following days wrapped up the children themselves and told us about how the child behaves during swaddling and whether was there a desired effect. After a month, we met parents again and personally summarized the effects of wraps on their baby and the changes that occurred after swaddling. Results: In the qualitative survey, we found out that most parents use wraps to calm down and soothe the child. Most mothers reported using quick wraps, classic lace wraps or a combination of both. Half of the surveyed mothers said that after using wraps were their children calmer. The remaining third of the mothers said that swaddling helped to let their children to sleep better. Children of the remaining respondents did not feel well during swaddling and they were more teary and restless. Questions regarding age, education and place of residence showed that more than half of respondents have completed education with graduation, a third of mothers have an university degree. The youngest mother was at the time of our research 21 years old, the oldest was aged 38 years, the average age of mothers was 28.2 years. In the question regarding the residence, we found out that 19 of the interviewed mothers were living in a town and the remaining number, 14, were living in the smaller village.

This master thesis deals with the evaluation of the current state of parking on the estate Bažantnice in Hodonin, determining the required number of parking spaces according to CSN 73 6110 and CSN 73 6110 / Z1. The second part deals with the design of possible modifications of local roads. The aim is to increase the number of parking spaces in the area. A newly designed residential zone and zone tempo 30 leads to traffic calming.

The tendency is to create comprehensive documentation, based on the methodology for carrying out safety inspections, to serve the communications manager territory (mainly municipalities and cities) as a basis for usable implementation of proposed measures to increase safety, as well as Study for implementation of proposals contained in the projected future and implemented traffic-engineering measures on roads solved territorial unit.

I det hållbara planeringsidealet anses cykeln vara en viktig del av en fungerande trafiklösning, trots detta tenderar många städer ha problem att uppnå deras egna mål för ökad cykeltrafik. Studien analyserar Malmös och Köpenhamns cykelplanering och cykelvägsstruktur utifrån aktuell cykeltrafikforskning, i syfte att undersöka vilka strategier och förutsättningar som städerna har gemensamt, och vad som skiljer dem åt. Målet för studien är att få svar på hur, och i vilken mån Malmös cykeltrafikandel kan öka utifrån Köpenhamns exempel, och att få en vidare förståelse för de utmaningar som den framtida cykelplaneringen står inför. Studiens metod tar ansats ur fältstudier av fyra cykelfrämjande städer i Europa. Sammanställningen av fältstudierna resulterar i att tre cykelstrategier identifieras som gemensamma för de fyra cykelfrämjande städerna. Därefter analyseras Köpenhamns och Malmös cykelprogram utifrån de tidigare nämnda cykelstrategierna. Analysen fastslår att Köpenhamn borde ses som en framstående cykelstad och möjliggör för en jämförande analys mellan Köpenhamns och Malmös cykelsatsningar. Den jämförande analysen mellan Köpenhamns och Malmös cykelsatsningar avslutas med en redovisning och tolkning av resultaten från analysen.För att kunna förstå cykelprogrammens spatiala relation till städerna de är tänkta att implementeras i används en space syntax-analys. Genom att undersöka satsningarnas rumsliga kontext i förhållande till det befintliga cykelvägsystemet kan en djupare förståelse för cykelsatsningarnas omfattning och orsak uppnås.Studiens resultat identifierar tre strategier som är direkt kopplade till andelen cykeltrafik i städer. Den fastställer även att trots cykelsatsningarnas övergripande likheter, skiljer implementeringen och omfattningen av dessa satsningar sig åt mellan Köpenhamn och Malmö. Infrastrukturens stora påverkan på cykelutvecklingen i stort framgår även det i studiens resultat. Studien visar även på hur de båda städernas cykelprogram förhåller sig till cykelns socialt utjämnande egenskaper. Resultatet visar att det finns indikationer från båda städernas framtida cykelplanering på att dessa utjämnande egenskaper har fått en lägre prioritering allt efter cykeltrafiken anpassas till starkare samhällsgrupper. / In the sustainable planning paradigm, the bicycle is seen as playing an important role of combining effective, environmentally friendly, and space conserving transport to the compact city. Despite its overall positive effect on city life, many cities seem to struggle to achieve the goal of increased bicycle traffic. This study studies the similar strategies and efforts used by bicycle friendly European cities through current research literature, in order to analyze Malmö’s and Copenhagen’s efforts to increase their bicycle traffic. The goal of the study is to examine Malmö’s potential for increased bicycle traffic through Copenhagen’s bicycle planning strategies, and to get a deeper understanding of the challenge’s that may face the future field of bicycle planning. The study’s method starts in field studies of four bicycle friendly European cities. The compilation of the field studies identifies three bicycle planning strategies as mutual for all four cities. The mutual bicycle strategies are then used as a tool and benchmark for the analysis of Copenhagen´s and Malmoe´s municipal bicycle program. To understand the spatial relation between the cities bicycle strategies and the street network that they are supposed to be implemented in, a space syntax-analysis is performed. The results from the comparative analysis of the cities bicycle programs and the space syntax-analysis is then summarized and discussed. The result of the study identifies three crucial criteria’s that according to the study has a high possibility of affecting a city’s bicycle share. It also points to the importance of a well-developed bicycle infrastructure to achieve a higher level of competitiveness for the bicycle as a mode of transport. The study also highlights the socially balancing properties of the bicycle as a mode of transport, and the concern of losing these properties due to bicycle planning strategies that is starting to be adapted in order to attract people from more affluent social groups.
