Even though cars have a good effect on modern society, traffic accidents do not. There are traffic laws that define the regulations and aim to reduce accidents from happening; nevertheless, it is hard to determine all accident causes such as road and traffic conditions, and human related factors. If a traffic accident occurs, the traffic law classifies it as 'Negligence of Safe Driving' for cases that are not defined by specific regulations. Meanwhile, as Korea is already growing rapidly elderly population with more than 65 years, so are the number of traffic accidents caused by this group. Therefore, we studied predictive and comparative analysis of the number of traffic accidents caused by 'Negligence of Safe Driving' by dividing it into two groups : All-ages and Elderly. In this paper, we used empirical monthly data from 2007 to 2015 collected by TAAS (Traffic Accident Analysis System), identified the most suitable ARIMA forecasting model by using the four steps of the Box-Jenkins method : Identification, Estimation, Diagnostics, Forecasting. The results of this study indicate that ARIMA $(1, 1, 0)(0, 1, 1)_{12}$ is the most suitable forecasting model in the group of All-ages; and ARIMA $(0, 1, 1)(0, 1, 1)_{12}$ is the most suitable in the group of Elderly. Then, with this fitted model, we forecasted the number of traffic accidents for 2 years of both groups. There is no large fluctuation in the group of All-ages, but the group of Elderly shows a gradual increase trend. Finally, we compared two groups in terms of the forecast, suggested a countermeasure plan to reduce traffic accidents for both groups.

고령화가 급격한 속도로 진행되며 발생하는 문제 중 고령 운전자 사고는 해결되어야 하는 중요한 사회문제이며 사고를 감소하고자 하는 노력은 앞으로 맞이할 초고령 사회를 대비하기 위해 꼭 필요하다. 현재 고령자는 65세 이상으로 규정되어 있으며 이에 따라 고령 운전자 사고에 관련된 다양한 연구들은 65세를 기준으로 일반운전자와 고령 운전자를 구분하여 분석한다. 이러한 배경으로 인해 수용 가능한 정확도의 수준에서 실질적으로 교통약자로 분류되어야 하는 신체 능력을 갖춘 고령 운전자를 구분하는 기준은 제시되고 있지 않다. 따라서 본 연구에서는 상관분석을 이용하여 고령 운전자의 연령별 사고특성을 분석하여 연령군집별 사고 위험성을 비교하도록 한다. 분석결과 차종별 주요 사고특성에 대해 75세 이상의 경우 사고 발생에 미치는 영향력이 높아지는 것으로 나타났으며, 70세에서 80세 사이 구간에서 사고 발생 빈도가 상대적으로 낮았던 승용차에 대해서도 주요사고특성을 분석한 결과 75세 이상 84세 이하 구간에서 사고 발생에 대한 영향력이 높아지는 것이 두드러지게 나타났다. 이는 고령화가 진행되고 평균 수명이 늘어남으로써 고령자 구간 폭도 증가하는바, 고령자 내에서도 특성이 나뉘게 되며 본 연구를 통해 연령군집별로 사고 발생에 대한 영향력이 달라지는 것을 확인하였다.

The objective of this study is to analyze the needs and determine the requirements of elder drivers for effectively using In-vehicle Information System (IVIS), by reducing cognitive and physical impact on this vulnerable group. The persona method was used to determine the relevant characteristics of older drivers. Task analysis was performed in order to obtain general interaction problems of the personas when using a common function of recent days IVIS. The results were classified in the different usability goals as general requirements, specific needs. This study suggest improvement directions in order to develop an elderly friendly IVIS; in addition, different usability metrics were suggested. In this way, elder drivers would easily interact with new powerful functions supplied by IVIS of modern cars; while improving safety and comfort of an rapidly aging society.

Purpose With the recent development of Big Data and Artificial Intelligence technology, self-driving technology has developed into three stages (partial self-driving) or four stages (conditional self-driving), it is expected to bring a new paradigm to transportation in the city. Although many researchers are researching related technologies, there is no research on self-driving for disabled persons. In this study, the basic research was conducted based on the assumption that the shared self-driving car used by the disabled person is similar to the special transportation currently driving. Design In this study, data analysis and machine learning techniques were utilized to analyze the mobility patterns of disabled persons by type and to search for leading factors affecting the traffic volume of special transportation. Findings The study found that external physical disorders and developmental disorders often visit general welfare centers, internal organ disorders often visit general hospitals, and the elderly and mental disorders have various destinations. In addition, machine learning analysis showed that the main transportation routes for the disabled person use arterial roads and auxiliary arterial roads and that the ratio of building usage-related variables affecting the use of special transportation for a disabled person is high. In addition, the distance to the subway and bus stops was also mentioned as a meaningful variable. Based on these analysis results, it is expected that the necessary infrastructure for shared self-driving cars for disability person traffic will be used as meaningful research data in the future.

Due to the ageing-related degradation in physical and cognitive abilities, the elderly have difficulty in car driving and this is related to the high rate of car accidents among them. This study investigated the kinematic characteristics of old drivers' steering in right turning at intersections by comparing with young drivers. Thirteen old(60~70) and thirteen young(20~30) drivers who participated in the experiment turned their cars right side at intersections in a driving simulator. As results, the completion time of right turning at intersection of old drivers was larger than that of young drivers. The speeds of vehicle at the beginning and ending point of the right turning area of old drivers were smaller than those of young drivers, and also the steering angle at the ending point of the turning area of the former was smaller than that of the latter. The normalized jerk of old driver's steering was significantly larger than that of young drivers. These results indicate that old drivers modify their steering movement repeatedly and take the driving strategy of avoiding risks due to their reduced physical capabilities.

Downtown cities in Japan are facing sharp fall in customers and continued shut down of shops due to decrease of population, increase in family cars and flowing of customers into the suburban large-scale retail stores. Omura City in Nagasaki Prefecture, Japan is no exception to this. For the revitalization of the downtown, many actions have been taken to open the vacant shops. However, transportation problem is the most important one to be solved for the citizens including the elderly people having difficulty in movement. Accordingly, this study was aimed at the revitalization of the downtown by substantiality public transportation. We have attempted to develop routes from the view-point of convenience by using Analytic Hierarchy Process (AHP) and Geographic Information Systems (GIS). As a result of the study, we were able to select three bus transportation areas by incorporating qualitative factors into the analysis. Finally, the study concluded that, revitalization activities of the downtown city itself is required in addition to re-structuring of bus transportation system for the revitalization of the downtown city.

Purpose: The purpose of this paper was to compare community health status by region and to investigate related factors using community health and social indicators. Methods: Data were collected from statistics of local districts that were provided by KNSO and KCDC. ANOVA and correlation were analyzed using PASW 18.0. Results: The standardized cancer mortality rate was higher in metropolitan areas than in other areas. On the contrary, the mortality of respiratory disease, traffic accident, and suicide were higher in rural areas. Small cities and county districts showed higher prevalence in obesity prevalence than metropolitan areas. Metropolitan areas presented higher prevalence in alcohol drinking during the previous month, perceived stress, and seat belt use. The age-adjusted standardized mortality rate was correlated with higher prevalence of smoking, obesity, percentage of the elderly, number of beds, number of social welfare facilities, number of registered cars, lower percentage of financial independence, number of doctors, and percentage of water supply service & sewage. Conclusion: Since significant differences in mortality rate and prevalence of health risk behaviors exist between regional areas and the mortality rate was correlated with other social indicators and health indicators, health policies and social policies considering these differences should be develop and implemented to the communities.
