PURPOSE: A pedestrian network generation method which utilizes existing spatial information is provided to automatically establish a pedestrian network, thereby reducing time required for pedestrian network establishment. CONSTITUTION: A pedestrian network generation method which utilizes existing spatial information is comprised of the following procedures. A main memory receives existing first spatial information as input data. Pedestrian space is extracted from the first spatial information in order to arrange a surrounding region of a first main road into a linear shape(S10). Pedestrian space for the linearization of inside of a block surrounded by a main road of a second-step construction target region is extracted from existing second spatial information(S20). A first class basic network is generated through a linearization process using a program within a main memory. A second class basic network is generated through the linearization process using the program within the main memory. A node-link network structure is created using the program within the main memory by merging gateway information extracted from a gateway layer and the basic network.
