The line will be 15 kilometers long and with a total 21 stations. There is no doubt that the completion of M4 would improve the public transportation system and bring more new opportunities for urban development. Based on the changes of the two public transportation-related indicators, the development potential and risk of each commercial land use pattern could be evaluated by comparing the probability ranking in each land returned by the static prediction model.
