We explore the scaling relation between the population and the public transportation system of urban buses for the two cities Daejeon and Gwangju where urban buses are the central to public transportation. These two cities are metropolitan cities in the Republic of Korea with very similar areal sizes and populations. In terms of the transportation service volume, the number of buses operating on one day and population follow a scaling law with an exponent close to 1. In terms of transportation service accessibility, the number of bus stops and population follow a scaling law with an exponent lower than 2/3. An exponent of 1 reveals that the transportation service is provided in proportion to population. An exponent lower than 2/3 reveals that the bus stops, which provide access to the transportation service, are expected to be more evenly distributed spatially.
