Assuming as the Same in Applying Regulations ReferencesSummary The operational definition of a smart cell and the process of producing informationabout smart cells can be understood as follows for the purposes of this study. A smartcell is the minimum unit of territory in which individual spatial information (e.g., personalcharacteristics and location) is identifiable in real time.Smart cells can track the behavior of individuals through space by means of lines(representing movement) and dots (representing individuals), which can be seen movingin and out of smart cells. Data for this purpose are collected by mobile phone basestations and processed by wireless service carriers.Smart cells have a number of applications in transportation and spatial planning policy,as data from smart cells are scalable and can thus be extrapolated to different spatialhierarchy levels such as towns and regions.This research sought to analyze activity in the Seoul metropolitan area along gender andage lines at different times of the day. The central focus of activity in the city was foundto shift over the course of a day, from Seoul’s south side at 7 a.m. to north side by noon,and back south again by 6 p.m.On the demographic distribution for age groups, the analysis showed greater activity insouthern Seoul among men, whereas women were more active in the city center.This study tracked human activity in real time in Gangnam-gu (ward), an upscale andbusy area in southern Seoul, using mobile big data generated by smart cells. Humanactivity, the survey found, was highly concentrated near subway stations, especiallyGangnam and Yeoksam. Weekend activity was also monitored in and around SeoulLand, one of the capital region’s most popular amusement parks, and parking lots sawpeak levels of congestion Saturdays between noon and 3 p.m.Smart cells are likely to prove extremely helpful in the event of a natural disaster orother emergency thanks to its ability to provide real-time information on human activityin a specific location, including the number of people and their precise coordinates.This study evaluated the utility of smart cells in a hypothetical disaster scenario in whichan extreme heat wave hits Jongno-gu, an administrative ward in central Seoul. In theevent of a predictable, slow-occurring disaster such as extreme heat wave, smart cellshave applications in three stages: the advance warning stage, in which authorities issuean excessive heat advisory and urge appropriate precautions; the emergency stage, inwhich they prepare to evacuate people in high-risk areas; and the evacuation stage.The scenario analysis demonstrates that smart cells can be used in developing countriesin the following four ways:First, smart cells can help build statistical databases for the purpose of betterunderstanding population trends and the habits of the economically active population.Developing countries tend to lack basic statistical data on such matters because ofbudget constraints and underdeveloped social institutions. As this study shows, wirelesscarriers’ databases and mobile big data can possess significant information about humanactivity in any country with a high rate of mobile phone penetration. By using smart cellsto gather basic social statistics that could otherwise be obtained only through surveys,developing countries stand to save significant time and costs.Smart cells also enable spatial planners to implement policies at different levels withinthe spatial hierarchy (e.g., nation, region or city). National territorial policy transcendsboundaries such as those between new and old city centers. Smart cells can help achievepolicy objectives at different levels in the spatial hierarchy; it commands high value formacro spaces such as countries and regions, as well as micro spaces such as towns anddistricts.Smart cells also have business applications. Merchants who wish to start smallbusinesses can preemptively use the data to reduce their risk of failure. Equipped witha clearer understanding of trends in human activity in a given area, entrepreneurs canbe better prepared to serve their potential markets. In developing countries, manynew entrepreneurs have recently moved to large cities and lack knowledge about theirrespective markets. Information obtained through smart cells can prove indispensablefor such a purpose.Furthermore, smart cells can be incorporated into disaster prevention and responsesystems. Mobile big data is a mobile phone-based system of automatic data collectionthat enables constant monitoring of the number of people in a given area who areespecially vulnerable to a natural or social disaster. Continuous monitoring is aneffective tool for disaster prevention in regions at high risk of natural or social disaster.Developing countries with insufficient databases for basic statistics can use smart cellsin the event of a disaster to forecast the number of casualties and devise effectiveresponses. In the event of a disaster, this technology can send to emergency responseteams highly reliable information in a timely fashion to expedite the decision-makingprocess and minimize casualties.
