There are many studies conducted on cognitive performance and of different aspects that can affect the performance. However, the literature review reveal that there is a knowledge gap in the area of measurements for bicycle stability and in how bicycle stability is affected during acute alcohol intoxication. The aim of this study is, therefore, to investigate if different group characteristics such as cycling experience, physical activity, sensation-seeking, or previous alcohol habits have an effect on bicycle performance or executive functions during acute alcohol intoxication. The method of the study was to measure stability while bicycling on a tread-mill and give participants doses of alcohol until a Breath alcohol concentration (BrAC) level of approximately 0.8‰ was reached. The results showed that cognitive performance was almost unaffected for the different groups studied. The results of bicycle stability were almost equal in effect of time among the four different group characteristics in both Roll and YAW measurements. Three of the group characteristics showed a main effect or a tendency for interaction effect of group by time. The conclusion is that the measure of Roll, the vertical orientation on a bicycle, maybe is the most effective stability measurement for bicycles.

This report aims to investigate the economical possibilities of implementing mobility services, such as electrical carpool and electrical bicyclepool, in the upcoming mobility house Brandmästaren in Rosendal, Uppsala. A model based on a travel habit survey in Uppsala has been developed in order to calculate the need of vehicles. Thereafter the financial profits are calculated depending on the need of vehicles and according to different scenarios regarding how many people that potentially will join the mobility hub. The profits are then compared to the profits from a conventional parking house, in order to decide whether the mobility system is economically viable. The results concluded the following. The most suitable mobility system for Rosendal includes 104 bicycles, 36 cargo bicycles and 94 cars. For a supplement rent of 50 SEK per user connected to the mobility center, the break-even point for the business model where bicycles are rented is when 30.56% of the residents are connected to the system. For the business model where bicycles are bought the break-even point is 18.28%. A sensitivity analysis on the number of hours the service is assumed to be used showed that the profitability would not change to a significant extent. The highest break-even point after the sensitivity analysis was 34.40%. After comparison to other mobility services in Sweden, the conclusion was that the number of connected users needed was relatively low, hence the results shows that the mobility house has the potential of being more profitable than conventional parking house.

El crecimiento económico y social que afronta el país en la actualidad ha traído como resultado un gran incremento de la demanda de viajes en las zonas urbanas de Lima Metropolitana; esto se ve reflejado en el incesante aumento de transporte privado y público, lo que da a lugar a la congestión vehicular, diversos accidentes de tránsito y elevados niveles contaminación ambiental y sonora. El flujo vehicular ha aumentado, no solo en avenidas principales, sino también calles secundarias, por vehículos particulares y de transporte público debido a que el parque automovilístico en el Perú ha aumentado en estos últimos años. Llegando a alcanzar hasta Julio del año 2018 un aumento del 5.5% anual, así lo indica el informe técnico N°09 de la INEI y el MTC. Es por esta razón que es necesaria la implementación de otras alternativas para el transporte privado y que sirva como apoyo al transporte público. La importancia de establecer una solución al importante tráfico que se vive en las calles diariamente ha concluido en la utilización de la bicicleta como medio de transporte cotidiano. En los últimos años, ciudades como Bogotá, en Colombia y Santiago en Chile han logrado que la bicicleta pase ser un modo de transporte recreativo a ser también un modo de transporte urbano cotidiano y eficiente. Sin embargo, Lima ha mantenido el porcentaje de personas que usa la bicicleta, ya sea de manera recreativa o laboral, en un 0.5% de la población, según el FONAM. Asimismo, los 150 km de ciclovía establecidas hasta la actualidad presentan falta de funcionalidad, planificación y deficiencia en el diseño geométrico de la interconectividad entre estas. Por lo tanto, en la presente tesis se analizará la aceptación de una ciclovía que conecte las estaciones de la Av. Angamos de dos medios de transporte masivo como lo son el Metro y el Metropolitano de Lima y se propondrá una ruta que cumpla con las bases de tiempo, infraestructura y accesibilidad de manera que cumpla eficientemente las necesidades de los usuarios de llegar a tiempo. / The economic and social growth that the country is facing nowadays has resulted in an unceasing increase in the demand for travel in the urban areas of Metropolitan Lima; This is reflected in the constant increase in private and public transport, which leads to high traffic congestion, accidents, environmental pollution and noise. The traffic flow has increased, not only in main avenues, but also secondary streets, by private vehicles and public transport because the automobile fleet in Peru has increased in recent years. Reaching until July of 2018 an increase of 5.5% per year, as indicated in the technical report N ° 09 of the INEI and the MTC. It is for this reason that it is necessary to implement other alternatives for private transportation and to serve as a support to public transport. The importance of establishing a solution to the important traffic that lives on the streets daily has ended in the use of the bicycle as a means of daily transport. In recent years, cities such as Bogotá, Colombia and Santiago in Chile have made cycling a recreational mode of transport and also a daily and efficient mode of urban transport. However, Lima has maintained the percentage of people who use the bicycle, either recreationally or work, in 0.5% of the population, according to the FONAM. Likewise, the 150 km of bikeways established to date present lack of functionality, planning and deficiency in the geometric design of the interconnectivity between them. Therefore, in this thesis will be analyzed the acceptance of a bikeway that connects the stations of Av. Angamos of two means of mass transport as they are the Metro and the Metropolitan of Lima and a route that complies with the bases will be proposed of time, infrastructure and accessibility in a way that efficiently meets the needs of users to arrive on time. / Tesis

abstract: Bicycle stabilization has become a popular topic because of its complex dynamic behavior and the large body of bicycle modeling research. Riding a bicycle requires accurately performing several tasks, such as balancing and navigation which may be difficult for disabled people. Their problems could be partially reduced by providing steering assistance. For stabilization of these highly maneuverable and efficient machines, many control techniques have been applied – achieving interesting results, but with some limitations which includes strict environmental requirements. This thesis expands on the work of Randlov and Alstrom, using reinforcement learning for bicycle self-stabilization with robotic steering. This thesis applies the deep deterministic policy gradient algorithm, which can handle continuous action spaces which is not possible for Q-learning technique. The research involved algorithm training on virtual environments followed by simulations to assess its results. Furthermore, hardware testing was also conducted on Arizona State University’s RISE lab Smart bicycle platform for testing its self-balancing performance. Detailed analysis of the bicycle trial runs are presented. Validation of testing was done by plotting the real-time states and actions collected during the outdoor testing which included the roll angle of bicycle. Further improvements in regard to model training and hardware testing are also presented. / Dissertation/Thesis / Masters Thesis Mechanical Engineering 2020

Master thesis titled “Analysis of selected manoeuvres of bicyclists” in the first part deals with the history of bicycles, construction, division of bicycles and introduces–traffic accidents of cyclists and national legislation. Practical measurements with bicyclists is in the second part of this thesis. Cyclists performed deceleration on three surfaces, acceleration and a manoeuver, in which cyclist looked behind himself before changing the direction. The evaluation of all measurements and comparison with other similar works has been made in the last chapters.

This diploma thesis looks into the area for sport and recreation in Brno-Komárov. The main part is the project of new arena for track cycling for Favorit Brno. Part of the assignment is also the solution for urban plan and redevelopment of the large area in the south of Brno in city district Brno-Komárov. Urban plan design is framed as conversion of the whole space into sport activities area for broad public. The velodrome itself is based on the idea of a bicycle and its parts as architecturally interesting part of the building, in this case particularly lacing of a wheel. Stadium could become new landmark for its surroundings and draw attention of the general public.
