The thesis focuses on the analysis of the existing bicycle transport infrastructure system within Ljubljana and suggest appropriate arrangements bike lanes, trails or mixed-profile bike arrangements. The criteria that we have in the design take into account: the number of active participants involved in cycling, age and physical and mental qualities / skills, the number of individuals who would be the appropriate arrangements for the safe routes and want to include in the future, sufficient traffic safety, link currently unconnected routes to major routes, tourist attraction bike routes. We carried out a survey on cycling in the Municipality of Ljubljana (MOL) during a random population of cyclists and people who do not cycle, and in the field to investigate the current situation. The results showed that respondents perceive a lot of damage to the upper layers of the road cycling, which often threaten the security of the participants and missing links across certain parts of the city. When viewing the terrain they were observed deficiencies: considerable areas of poorly maintained cycling carriageway area degraded or insufficient transparency of the crossing of bike routes and paths through the roads and in the integration of bicycle lanes on the carriageway, together with other motorized traffic. The Municipality of Ljubljana propose legislation bicycle transport infrastructure improvements to the existing bike links with the rehabilitation, equipment and security measures in the individual sections, and the update and link them into meaningful regulated cycling network - an area that is closed to the ring and inside the well criss with cycling links.
