Abstract
One of the most important issues in public transportation oriented urban structure is pedestrians′ accessibility to public transportation station. Pedestrians′ accessibility is influenced by socioeconomic conditions such as personal income and location of working places as well as primary factors such as access time and distance. The purpose of this study was to construct a comprehensive transportation selection model using a logistics model in order to understand the influences of various variables on accessibility focusing on subway stations in new towns in metropolitan areas and to set the proper distance for pedestrians.
According to the results of the study, we can see that the most influencing factors on the use of subway were possession of vehicles, age, distance and income. It was analyzed that people with annual incomes under 50 million won and who lived in a space smaller than 30 pyung used subway most frequently. Additionally, the threshold distance for walking was 700m primarily and 1,100m secondarily. We can increase subway utilization by walking through dense housing layout in this area.
