The pedestrian road network in mountainous cities has distinctive features when compared to that in flat cities. This study proposes a three-dimensional analysis method for measuring the accessibility for pedestrians in a mountainous city considering both the metrical attributes of mountainous street networks and a pedestrian's behaviors. The objectives are firstly to create a method to analyze the accessibility based on existing theories, secondly, to modify coefficients after analyzing the properties of the mountainous pedestrian road network, and lastly, apply the method for measuring the accessibility both in mountainous areas and in areas assumed to have elements similar to those of a mountainous pedestrian road. The results of the analysis are as follows. First, the usability and rationality of the method are demonstrated by simulation and application. Then, the accessibility is quantified and interpreted visually for practical use. Lastly, the characteristics of accessibility in mountainous cities are presented.
