The purpose of this study is to identify the intent of the Total Amount of Vehicles policy that is enforced during the two summer season months (July and August) in U-do and the consequent problems after its implementation. We propose a basic direction for the policy to be sustainable. The average daily number of vehicles visiting was 645 in July 2015 and 953 in August 2015. As these numbers exceed the limit of 605, serious transportation problems such as traffic congestion and traffic accidents have occurred in U-do. We propose that the future direction of the policy is set forth as follows. First, mandatory reporting and the use of insurance, such as motorcycles, will have to be introduced along with measures to regulate violations. Second, a scheme needs to be introduced to enhance the total Amount of Vehicle policy and the number of inbound vehicles. Finally, public transportation cooperatives that are directly managed by local residents need to be established and an Eco-friendly vehicles dissemination policy introduced.

Road traffic accidents (RTAs) are the leading cause of accidental death among children. RTA reduction is becoming an increasingly important social issue among children. Municipalities aim to resolve this issue by introducing "Smart Pedestrian Crosswalks" that help prevent traffic accidents near children's facilities. Nonetheless such facilities tend to be installed in relatively limited number of areas, such as the school zone. In order for budget allocation to be efficient and policy effects maximized, optimal location selection based on machine learning is needed. In this paper, we employ machine learning models to select the optimal locations for smart pedestrian crosswalks to reduce the RTAs of children. This study develops an optimal location index using variable importance measures. By using k-means clustering method, the authors classified the crosswalks into three types after the optimal location selection. This study has broadened the scope of research in relation to smart crosswalks and traffic safety. Also, the study serves as a unique contribution by integrating policy design decisions based on public and open data.

The purpose of this study was to estimate the socioeconomic costs resulting from alcohol drinking among adolescents as of 2006 from a societal perspective. Methods: The costs were classified into direct costs, indirect costs, and other costs. The direct costs consisted of direct medical costs and direct non-medical costs. The indirect costs were computed by future income losses from premature death, productivity losses from using medical services and reduction of productivity from drinking and hangover. The other costs consisted of property damage, public administrative expenses, and traffic accident compensation. Results: The socioeconomic costs of alcohol drinking among adolescents as of 2006 were estimated to be 387.5 billion won (0.05% of GDP). In the case of the former, the amount included 48.25% for reduction of productivity from drinking and hangover, 39.38% for future income losses from premature death, and 6.71% for hangover costs. Conclusions: The results showed that the socioeconomic costs of alcohol drinking among adolescents in Korea were a serious as compared with that of the United States. Therefore, the active interventions such as a surveillance system and a prevention program to control adolescents drinking by government and preventive medicine specialist are needed.

PURPOSES: This study is to find the substantial shortcomings embedded in the government policies and practical administrative processes associated with the Korean Transportation Database (KTDB) and to propose preliminary approaches to overcome. METHODS: Administrative and socioeconomic issues on inefficiency in public and private investment and redemption was found from the literature review. Through the interview of sets of experts and practitioners, a set of faultiness embodied in the administrative procedure utilizing and managing KTDB was found and analyzed. RESULTS: This study found the erroneous administrative elements categorized into four groups: faulty socioeconomic data supporting local governors's optimistic will yielded overestimation of future traffic demand; faulty data incidentally introduced in KTDB burdened traffic demand analysis; unavoidable misuse of KTDB worsened the unstability of KTDB; and apathy to manage the KTDB data deviated systematic management. The proposed includes the alteration of the administrative and technical systems to overcome those shortcomings. CONCLUSIONS : Erroneous administrative elements associated with KTDB should be concerned prior to indicating subsequential faultiness in demand analysis.

According to the statistics, Korea is expected to reach a super-aged society in 2025. In preparation for an aging society, The government is making efforts to improve in social activity and welfare for the elderly people. But in case of people who live in urban-rural mixed cities, They can not benefit from traffic convenience that is essential in social activities. For example, surveys and interviews show that, The dwellers(65+ of some urban-rural mixed cities) have many restrictions on social activities because of mobility disadvantage. Therefore, We propose that expansion for the people who need to use the voucher taxi, Increase of the public bus service and rebuilding of the bus stop terminal. We are looking forward to this study will be used as basic data for transportation policy of urban-rural mixed cities across the country.

Objective: The purpose of this study was to understand the needs of teachers in daycare centers for preschoolers in providing health education and health care services and to identify competencies and barriers to health education among the teachers. Method: A total of 410 teachers from 496 public daycare centers were recruited. Participating daycare centers were selected using a stratified sampling method. Data were collected from June to August 2002 using mailed questionnaires. Result: About 37% of the daycare centers provided health education more than 6 times during the past year and 92% provided annual health screenings. Traffic safety, personal hygiene, and sexuality education were most frequently provided. Regarding in-service education for daycare teachers, 62.7% had obtained health related education. Sexuality education, traffic accident, and injury prevention were the main topics for the in-service education. The teachers had relatively higher competencies and lower barriers to health education, while they also had proper knowledge related to health of children. Conclusion: Based on the study results, health professionals could plan and develop health promotion programs to meet the needs of teachers and children in daycare centers.

Gyeonggi-do comprises several types of areas, including urban, semi-urban, and rural areas. The availability of public transportation services varies depending on the area types, but the fare structure is based on a simple transfer rule, i.e., a transfer is free when completed within 30 minutes. As a result, users in non-urban areas with a poor frequency of public transportation services do not receive transfer discounts because most of the bus routes in these areas have a gap of more than 30 minutes between services. In terms of equality of opportunity, the transfer rule is being applied unfavorably and, as a result, equality of opportunity of the non-urban commuter is severely affected. Therefore, this study analyzed the user benefits mainly stemming from transfer fares using the smart card data of commuters using public transportation in Gyeonggi-do. An index called the beneficiary rate of the free transfer was developed and a scenario analysis was conducted based on the various levels of the rate. The results of this analysis proved that the users of public transportation services in non-urban areas in Gyeonggi-do can only receive transfer benefits by the extended time for free transfer and not by the implementation of a uniform policy irrespective of the type of area. The study also suggested an equitable fare transfer system and policy alternatives.

In public transportation, smart cards have been introduced for the purpose of convenient payment systems. The smart card transaction data can be utilized not only for the exact and convenient payment but also for civil planning based on travel tracking of citizens. This paper focuses on the analysis of the transportation convenience using the smart card big data. To this end, a new index is developed to measure the transit convenience of each region by considering how passengers actually experience the transportation network in their travels. The movement data such as movement distance, time and amount between regions are utilized to access the public transportation convenience of each region. A smart card data of five working days in March is used to evaluate the transit convenience of each region in Seoul city. The contribution of this study is that a new transit convenience measure was developed based on the reality data. It is expected that this measure can be used as a means of quantitative analysis in civil planning such as a traffic policy or local policy.
