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.
