For decades, the Taiwan government has constructed a complete highway network for the purpose of providing passengers with more route choices and enhancing the quality and efficiency of transportation. Since in the past the roadway network were not systematically planned, road signs were plagued by inconsistency. Therefore, in this project, we made a spatial roadway network based on GIS. So repeated or meaningless information will not influence passengers and then further features of the highway network can be developed.
