The aim of this paper is to develop a method for describing urban patter by means of simple mathematical calculations applicable for urban design. Two approaches were used and combined with one another. The first approach was Stephen Marshall’s method for calculating T-junctions and X-junctions seen in relationship with a cul-de-sac and network type of street grid. The second approach was to use the space syntax method. Finally the results from these two approaches were overlapped with one another.
