According to the European Commission, cycling (and walking) is considered an active mobility mode which, besides being of low cost and without emissions, can also bring about health benefits to society. A bike lane network along with the walkways and the public pedestrian areas with which it often intermingles can largely transform the visage of a city, its transportation system and in general the way the city functions in a positive way, given that the network has been properly and adequately planned. This paper aims at providing an analysis of the bicycle lane network of the city of Larissa, an average sized city, as regards its relation to the general notion of urban planning, the technical implementation, whether the interconnection of the distinct urban areas can be achieved and how through that network. We consider the bike lane network as a layer of nodes and axes which ideally should cover, interconnect and coincide with the main urban centers and land uses of the city when superimposed upon the urban grid. Finally, proposals will be made for further research about the way an urban network should be developed, emphasizing on the importance of nodes, axes, and interconnection among the main urban compartments and using in a new harmoniously combined way the planning tools of architecture, mathematics and possibly informatics.
