Traffic demand. The layout of subway lines also needs to consider the traffic demand. If the population density and traffic flow in Shi Qi area are low, the subway lines will not extend to this area, or there are fewer subway stations in Shi Qi area, resulting in less traffic demand and a longer interval between the newly-built stations and the stone base station. The newly-built station is the station of Guangzhou Metro Line 4, which was opened in June 5438+February 2005. The main color of the station is red. The station is located on the ground floor of Zengbian Village, Xinzao Town, Panyu District. The station adopts an island platform with four exits.
