Korean road transportation system in Joseon dynasty had been described by many topography books published between 18^<th> to 20^<th> centuries. There are several lines of trunk roads called 'Daero' all started from Seoul (Hang Sung), capital city, to all over the peninsula where country border to China, Japan and Manchuria, or special interests such as militarily important places, royal tomb, national archive, had located. However, trunk road networks were different in detail by each topography since there was no official definition by central government. They controlled land transportation not by existing lines but postal stations distributed in each region. Therefore, authors of these topographies had to develop and improve trunk line network by themselves. The number of trunk line is 5 to 10 depends on topographies. There were common route for all books so-called '6 Daero,' which build national framework for land transport. Then some topographies added 0 to 4 extra lines which looked relatively less important as trunk route, but still important for specific purposes. Most sections of these lines were straight shape like Roman Road as a reflection of absolutism of central power and geopolitical reason around this peninsula, even if avoiding major cities along the line.
