A Construction Method of Pedestrian Road Networks for Agent-Based Evacuation Simulation

We propose a method for constructing pedestrian road networks with publicly available geospatial data sets. Our method consists of two algorithms: estimation of road widths and deployment and connection of pedestrian road segments. In the two algorithms, we used two types of geospatial data: the set of road center line segments and the set of road edge segments. The experimental results show that the estimation algorithm of road widths can calculate precise road widths and the construction algorithm of pedestrian road networks works well even for road networks with a complicated connecting relationship.
