This study analyzes the influence factors on elderly pedestrian accident. Elderly people are easy to be badly injured by car accidents compared to younger people. Therefore, various plans and measures are required to protect elderly pedestrian from accidents. However, pedestrian accidents studies only focused on microscopic factors such as attribute of driver, pedestrian, road design. In order to prevent pedestrian accident and reduce the severity of the accident, not only microscopic factors but macroscopic variables such as urban planning and facility should be considered. In this regard, this study develops an ordered probit model introduced the characteristics of urban facility which were not considered in the previous studies. The result shows that there is higher level of accident severity in suchareas as large commercial area, well-developed area with transportation infrastructure service and non-pedestrian safety zone. Thus, various and appropriate countermeasures should be prepared in order that pedestrian accident can be prevented in the areas mentioned above. In addition to the aforementioned variables, it is revealed that other variables including vehicle speed, gender and age of pedestrian, weather condition, type of vehicle, etc. partly affect the severity of pedestrian accident.

교통카드는 현재 수도권을 포함한 약 150개 지역에서 이용하고 있으며, 대중교통, 시내버스 노선개편, 대중교통 이용 수요 등 다양한 공공부분의 정책 기초자료로 활용되고 있다. 그러나 교통카드 데이터를 사용하는 지역중 수도권 및 일부 광역시를 제외하고 기존 BIS 정보와 미 매칭 또는 교통카드 자체에 버스 노선별 정류장 정보가 부재한 지역이 많다. 본 연구에서는 이러한 교통카드 기반정보 중 버스 노선별 정류장 정보를 생성하는 모형을 제시하였으며, 연구에서 제시한 모형을 통하여 추출 및 생성된 노선별 정류장 정보를 실제 BIS 정류장 정보와 매칭하여 정확도를 산정하였다. Smart cards are currently used in about 150 locales, including the metropolitan ares, and are utilized as a policy base for various public areas, including public transportation, bus fares, and public transportation requirements. However, excluding the metropolitan area and some metropolitan areas, there are many areas where the existing BIS data was unable to match station information on the data and Smart cards itself are not available on the bus stop information by the line. The purpose of this research was to produce bus stop information generated by the bus stop based on the bus route, and the actual stop information generated by the model presented in the study was derived by matching the actual station information.
