Illegal on-street parking in urban street spaces is still common, although the ratio of parking lots to the number of cars in Korea is almost 100%. Indiscriminate illegal on-street parking comes with various social costs, such as inconveniencing pedestrians, road congestion, safety threats, and poor quality of the street environment, while proper on-street parking provides benefits such as reducing vehicle speed and revitalizing street space. Therefore, it is necessary to strategically manage on-street parking to guarantee equity among various users of the street and to raise the public nature of street spaces.
