서울시 스마트 조명관리사업의 생활환경개선 편익

Smart street-lighting management(SSLM) is a central control and monitoring system for the efficient management of public lights in Seoul. SSLM helps to prevent light-pollution by dimming (adjusting the brightness of the light) and off-lights at night by remote control system. So it improves the living environment in Seoul. This study attempts to estimate the economic benefits accruing to citizens of Seoul from SSLM project. To this end, contingent valuation survey was conducted with a random sample of 500 households in Seoul, and a spike model was applied to dealing with a considerable amount of zero willingness-to-pay(WTP) observations(43.3%). The results show that the mean WTP for implementing the SSLM project is estimated to be 5,096.1 Korean won per household per year. Thus total annual benefits of the betterment in life environment with the SSLM in Seoul approximately amount to 18.2 billion Korean won. This information can be utilized in decision-makings related to management of public lights and energy use.
