The largest number of electric vehicles in Dongguan are concentrated in the bustling business district of the city. According to Baidu map, downtown bustling business districts include Guancheng, Cheng Nan, Dongcheng, John Wan business districts, shopping centers, food streets and other crowded places. Because Dongguan is a highly developed city in industry and manufacturing, many citizens have electric cars as a means of travel. In addition, the traffic in Dongguan city is busy, and traffic jams occur from time to time, while electric vehicles are relatively light and suitable for shuttling in urban areas, so they are also favored by many citizens. At the same time, the Dongguan municipal government has actively promoted the use of electric vehicles, and built many special lanes and charging piles for electric vehicles to encourage citizens to use electric vehicles instead of traditional fuel vehicles. These measures have further promoted the increase in the number of electric vehicles in Dongguan.
