Program-based algorithms for city map streets recognition pathfinder.

This article presents a street recognition and pathfinder algorithm. In addition, It explains the programming sequence of this algorithm by using Python and Processing programming languages. The algorithm deals with modified grid maps described by free and occupied cells. It recognizes streets inside the map and categorizes them into horizontal and vertical streets. The algorithm also has a search function to find the path between any two streets. [ABSTRACT FROM AUTHOR]
