  7. Abstract:
  8. This thesis examines the accessibility gap between different modes of transportation in Tehran Province, with a particular focus on public transportation and cycling. The main objective of this research is to calculate and analyze accessibility indicators to various land uses (such as commercial, service, and recreational) around metro stations using two modes of travel: cycling and bus-walking. The study utilizes simulations in Python and geographic libraries to compare these two modes of travel based on four key accessibility indicators: 1) nearest Opportunity, 2) cumulative opportunity, 3) average distance, and 4) gravity-based accessibility to measure the accessibility gap between the two modes of travel around Tehran’s metro stations. The findings of this research indicate that, according to the nearest land use, cumulative opportunity, and gravity-based indicators, cycling, as a green and sustainable mode of travel, offers better accessibility over shorter distances compared to buses. On the other hand, buses provide better accessibility in terms of average distance due to higher speeds. Additionally, the study reveals that in areas with high land use density and bus lines, such as the central and eastern parts of Tehran Province, the accessibility gap between the bus-walking and cycling modes is small. However, in the western and northern areas of Tehran Province (especially around Mir-Damad, Shahid Haqqani, Shahid Hemmat, and Mosalla Imam Khomeini metro stations), due to the greater distance between bus lines and the suitability of the cycling network, the accessibility gap is significant, with cycling being the superior mode of travel. This study can assist municipalities and transportation planners in identifying suitable areas for strengthening the cycling system or improving public transportation accessibility, thereby addressing last-mile travel challenges and enhancing the overall urban transportation system. Furthermore, the findings of this research can help citizens make optimal travel choices based on the needs and specific conditions of each area, ultimately reducing travel time and costs and improving the experience of urban travel
