Although China has a huge cyclist population, the cycling condition in large cities is undesirable. The problem is mainly caused by the mixed-flow of cyclists and motorist on the road. Separation of cyclists and motorist is the key to solve the problem. Based on the research of the successful examples in Europe and a PEBOSCA inventory analysis of the cycling traffic in Nanjing, a set of suggestion is proposed on how to plan the bicycle network. A bicycle network separated from motor traffic and the planning on a cycling district division is introduced. The proposal also involves the suggestion on combination between cycling and public transport, and the experience route of historical culture and the natural beauty of the landscape.

Bicycle traffic in Stockholm has varied a lot during the 18th century. During the latter part ofthe century, the city primarily funded the development of the city's public transportationsystem, rather than the bicycle infrastructure as many other cities did. The city ́ s bike mapsare seen as lacking and hard to read, which may be a reason for the bicycle share being lowerthan possible.The aim of the study is to produce a suggestion for a simplified bicycle network map overStockholm, in the same style as a public transportation map. Furthermore, Stockholm´sbicycle planning has been examined to gain a better understanding of the documents andactors involved in the city's bicycle planning, and the influence they have.The study was conducted through a literature study examining the bicycle infrastructure inStockholm and other European cities. The study primarily examined the factors contributingto a good bicycle network, but also how a route map can be developed and how heightdifferences along a bike route can be illustrated. In addition to the literary study an interviewwith a traffic planner at Stockholm´s municipality was conducted, giving a good look into thecity’s bicycle planning as well as presenting many different perspectives on the area. In orderto produce the map, the current bicycle infrastructure was surveyed, whereafter a map wasproduced based on the literary study´s design principles.It was found that Stockholm ́ s politicians to a large extent manage the bicycle planning, whichthe city´s traffic department then implements. The city bases its bicycle planning on its ownbicycle plan, which is complemented by the city’s detailed design handbook. The former isbased on Stockholm's vision and master plan, and describes the different types of bicycleroutes in the city along with the city´s objectives and goals for its bicycle planning. The actorwith the greatest influence on Stockholm ́ s bicycle planning is the city´s politicians, as theygovern and regulate the traffic department 's work. The department makes its ownprioritization in some cases, giving them some influence as well. Based on the surveying thatwas made, a map over Kungsholmen was created. The map can be useful in order to showpossible connections in the cycle network and encouraging inexperienced cyclists choosingthe bike.In order to further develop the map concept, the entirety of Stockholm should be mapped anddesigned. The map can be complemented by pathway markings and signage as it isimplemented further. Distribution of the map as well as digital solutions may be investigatedfurther.English title: From obstacle to opportunity: A study on factors affecting the attractiveness ofa bicycle network, and design of a user-friendly bicycle map over Kungsholmen, Stockholm.

Förbättring av cykling som hållbart transportmedel kräver skräddarsydda transportsystem. Svenska kommuner, som Vänersborgs, har påbörjat implementering av cykelplaner vid planering av infrastruktur. Med kommunens samtida mål om att öka invånarantalet från 39 000 till 50 000, är planens mål och riktlinjer för att utveckla ett högkvalitativt, säkert cykelvägnät som kopplar samman viktiga målpunkter och minskar olyckor. Denna avhandling utvärderar säkerheten och tillgängligheten över gång- och cykelvägnätet till skolor inom Vänersborgs kommun med hjälp av GIS-analyser, där fokus riktar mot barn i åldrarna 7–15 år, men även säkerheten över totala gång- och cykelvägnätet utvärderas. Studieområdet inkluderar Vänersborgs centrum, Öxnered och Vargön. Multikriterieanalys (Analytisk Hierarkisk Process) metoder med kombination av nätverksanalys användes för att bedöma GC-nätets säkerhet och tillgänglighet. Experter viktade olika kriterier för säkerhet, vilket ledde till säkerhetsklassificering i ArcGIS Pro. Inkluderade kategorier var Mycket god, god, mindre god och låg. Nätverksanalysen i ArcGIS Pro prioriterade rutter via gång- och cykelvägnätet och förbjöd rutter att färdas längs vägar med hastigheter över 80 km/h, med hjälp av verktyget Closest facility för att planera rutter till skolan och undersöka tillgängligheten. Resultaten visade att 48.33% av det totala GC-nätet klassificerades som mycket god, 1.89% som god, 26.14% mindre god och 23.64% som låg. Nätverksanalysen indikerade en tillgänglighet till skolor uppnår 73.98%. Trots en signifikant andel av GC-nätet uppnår mycket god säkerhetsnivå, noterades brister, specifikt vid mer urbana områden där vissa segment klassas som mindre god och låg. Sammantaget visar avhandlingen att medan GC-nätet generellt uppnår god säkerhet och tillgänglighet, förekommer märkbara brister. Att se över och eventuellt åtgärda dessa brister skulle främja utvecklingen av cyklandet i Vänersborgs kommun. / Enhancing bicycling as a sustainable transportation mode requires tailored transportation systems. Swedish municipalities such as Vänersborg are integrating bicycling into infrastructure planning. The municipality's aims to grow the population from 39,000 to 50,000, the plan aims to develop a high-quality, safe bicycle network connecting key destinations and reducing accidents. This thesis evaluates the safety and accessibility of the bicycle network to schools within Vänersborg municipality using GIS-based analyses, focusing on children aged 7 to 15, while also evaluating the safety of the total network. The study area includes Vänersborgcity center, Öxnered, and Vargön. Multi-Criteria Decision Making (Analytical Hierarchy Process) approaches coupled with network analysis were utilized to assess the network's security and accessibility. Experts weighted different security criteria, leading to a safety classification in ArcGIS Pro. Categories included very good, good, not so good, and low. The Network analysis in ArcGIS Pro prioritized bicycle routes and restricted roads with speed limits over 80 km/h, using the Closest Facility tool to route school access. The results indicated that 48.33% of the network was classified as very good, 1.89% asgood, 26.14% as not so good, and 23.64% as low. The network analysis indicated a 73.98% accessibility coverage to schools. Despite a significant portion of the network achieving a very good safety level, deficiencies were noted, particularly in urban areas where some sections were rated as not so good and low. Overall, the thesis reveals that while the bicycle network generally achieves good security and accessibility, there are notable shortcomings. Addressing these gaps is crucial for Vänersborg's efforts to promote cycling and support population growth.
