Quantitative descriptive research method was employed in this study. The population in this study were the corridors of the Trans Jateng bus plan, land use, the national urban system, and the surrounding community. The independent variable in this study was the distribution of planned Trans Jateng bus stop points in the Susuwono area, whereas the dependent variable was the appropriateness of the planned Trans Jateng bus stop points with user service distances and surrounding land use. Spatial analysis, environmental analysis, suitability analysis of bus stop locations, and buffering were utilized as data research methods. The results of the study showed that 1) the buffering of the planned bus stop points in the Surakarta area was categorized as maximal, 2) the service distance of the Trans Jateng bus plans in the Sukoharjo District area was categorized as moderately optimal to less than optimal, 3) the service coverage of the Trans Jateng bus stop points was categorized as moderately maximal up to less than optimal based on the buffer map of the planned Trans Jateng bus corridor in the Wonogiri District area. This study concluded that the Trans Jateng bus stop plan is dominated by moderately maximum service coverage.展开更多
