In the 1990s the Town Council of Udine adopted a sectorial town planning concerning the cycling traffic within its territory, In order to protect the safety of users and the same time promote the use of an ecological alternative to
cars.The following criteria have been assumed as fundamental objectives in the preparation of
the plan:
- ensuring bicycle traffic safety in respect to other kinds of mobility;
- promoting the role of cycling as an alternative to individual motorized traffic, thus - reducing its effects oftraffic congestion and pollution;
-improving accessibility to central urban areas and services currently penalized by congestion due to individual motorized traffic (in particular by using the opportunities

- arising from the opening of new passages and creating transit zones and bicycle storage);

- promoting cycling as a healthy habit and as a means to access to scenic routes;
- connecting the cycle lanes to the connective tissue made up of urban green areas and parks, sports areas, educational and recreational facilities to achieve the above objectives, it was necessary to apply some general
strategies, the main features of which are summarized as follows;
-identifying a set of cycle routes consistent with and ordered according to a hierarchical structure, with particular regard to the use of existing roaclways;
-researching, especially in urban areas, the maximum possible continuity of the identified routes
- giving priorityto routes systems of definition andprotection of cycle routes in thevicinity of road junctions (alsothrough the installation of newtraffic lights and the restructuringof existing trafficlights): settingup and activating bicycle storage facilities and parking area sinterchangeable with motorvehicles (public and private):

-The training process that led to thedefinition of the Plan was carriedout oy checking the space actually available on existing roadways,which have been considered the basic resource fo rthe realizationof the network. On the basis of this knowledge of available space,the cycle lanes general networkhas been designed, according tocriteria of continuity, diffusion, capillarity, modularity andglobality as indicated of the methods recommended. Thefollowing categories of cyclingroutes have been therefore defined: Structural routes: they constitutete backbone of the city cycling routes system and therefore corrie within the scope of absolute priority:

- local cycling subsystem: independent cyclinglanes meant especially for school users and the major centres of attraction for hikers, nevertheless in continuity with the structural roads

-other cycle routes (connecting routes): additional paths needed to connect the hike paths indicated by neighboring municipalities, by the Provincial Plan of Bike Trails and by touristicpaths within Torre and Cormornatural parks.The study has finally been accompanied by a study of interventions feasible in the short term and by a notebook of the technical elements that documents the solutions to be adopted for the design and construction of cycle lanes.
