The rapid urbanization in developing countries has caused trasportation problems that need to be solved. For that reason, the study evaluates the potential of cycling in the densely populated part of Kathmandu valley. Slopes and existing roads have been applied as the input cost rasters for finding the shortest cost routes between stations. By taking the average cycling velocity, time to travel from station to destination were compared with the average commuting time in the public transportation. The result comes out as similar time with the public transportation. Although the cycling seems potential replacement for public transportation commuters, in fact, there are some setbacks needed to be supported by the government to make it reality in future.
