In recent years, ulture combined with tourism has shown rapid global development, especially historical monument has become an important tourism type. Additionally, in the tourism field, transportation convenience influences the destination selections of tourists. The development of historical monuments contributes to the increase and expansion of tourism, and tourism goals can be achieved by using transport routes to send tourists to various attractions. We applied space syntax to investigate the current spatial structure of transport in Tainan City, and combined the data with historical monument locations to conduct correlation analysis.
Of the space syntax parameters, we selected four accessibility indicators, that is, global integration value, local integration value, connectivity, and control value. Additionally, the higher the value of each indicator, the higher the accessibility.
Regarding the spatial structure of Tainan City, the results show that the global integration value gradually decreased from the central and western areas moving outward, displaying a radial shape. The local integration value distribution was more dispersed, with numerous neighborhood centers in addition to the central and western areas. Regarding road network integration, the integration R-squared value of Tainan City was 0.1082. The R-squared value of 51 historical monument locations was 0.3171. Regarding the sensitivity analysis, the spatial sensitivity for the global integration value was 20% and 70% for national and city historical monuments, respectively. Sensitivity for the local integration value was 33% and 80% for national and city historical monuments.
