우리나라 노년층의 교통사고 사망자와 보행 중 사망 비율은 증가하고 있으나 노년층을 대상으로 한 안전대책이나, 안전시설 및 보행환경 개선 등이 미비하다. 이에 본 연구에서는 과적인 노인보행자 교통안전대책을 마련할 수 있도록 기초자료를 제공하기 위하여 서울시와 경기도 지역의 5개 노인종합복지관을 이용하는 노년층을 대상으로 노년층 보행자의 통행실태 및 교통안전의식, 보행행태를 알아보기 위하여 설문을 실시하였다. 그 결과 노인의 50% 이상이 매일 외출하는 것으로 나타났다. 또한 횡단보도를 건널 때 신호를 지키지 않는 차량으로 인하여 사고의 위험을 느끼며, 보행자 신호시간 부족하다고 응답하였다. 따라서 노인 보행자의 교통사고 예방을 위해서는 과속이나 신호위반이 잦은 곳에 과속 및 신호위반 단속카메라를 설치하고 도로폭이 넓은 곳에서는 보행섬을 설치하고 횡단보도의 보행자 신호시간 연장의 확대추진 등이 필요한 것으로 나타났다.

According to Traffic Accident Statistics, the fatalities of accident while crossing is over represented. So, more active safety countermeasure should be considered to reduce the frequency and degree of severity of pedestrian-crossing involved accidents. The study analyses the safety effects of the Crossing Safety Assistant System which is composed of Led-embedded crosswalk lightings, text displayer and audio waning device for the safety consciousness both pedestrian and vehicles at crosswalk area. Operating speed of vehicles is reduced with statistical significance, and the level of vigilance expressed by pedestrian head movement to check out the vehicle existence is improved.

It has reported that a median bus-stop island on an exclusive median bus lane (EMBL) has shortened a crossing distance unit, encouraged a pedestrian's illegal crossing, and increased the number of accidents in the area. This study presents (1) the analysis of inappropriate pedestrian crossing patterns collected on exclusive median bus corridors and (2) the estimated performance of safety barriers restraining the occurrence of those. Total 19,649 pedestrian crossing data collected at the 'Sookmyung-university' median bus-stop, and the inappropriate pedestrian crossing patterns among those were grouped in terms of time and space violations. Physical safety barriers restraining illegal pedestrian crossings were considered as an alternative, and its performance in safety was quantified through microscopic simulation with conflict analyses by using surrogate safety assessment model. The findings suggest the number of conflicts reduced be 24.9 percentages compared to the one of the present condition when the physical safety barriers are placed at each of the eight ends of the EMBL pedestrian crossing.

Network models for pedestrian flows have been studied in various ways. However, because of the simplicity and application, a number of researchers prefer the CA Model to analyze pedestrian's complicated behavior. These kinds of models based on Agent are being used as a microscopic analyzing method since it can easily adapt individuals' various characters and movement types. However, because pedestrians' movement can be (easily) effected by where they are and where they head, some models using the same rules have limit when considering pedestrians' every different movement. In this research, homogeneous section is defined as a similar movement type of individuals. With MDPM, we suggest simulation method explaining one-way walk and side-walk which could not be done in past.

This study identified the factors which affect pedestrian behavior using the tobit model with a descriptive analysis. Individual characteristics, household characteristics, zone characteristics were selected as the independent variables. Walking frequency and walking time was adopted for the variables which represent walking behavior. The results showed that the walking time models were superior than the walking frequency models. The model for education purpose had the most lowest fitness and the model for others purpose had characteristics mixed up the various purposes. Futhermore, this research found that independent variables: individual, household and zone characteristic variables affected walking activities of elderly pedestrian by purpose. The walking activity decresed when a pedestrian grew older or had a vehicle or a driver's license. The Elderly facilities promoted the walking activity of seniors. As the floor area of neighborhood and business facilities was wide, the walking activities were animated. In addition, the compacted downtown developments decreased the elderly's walking activities, so it is needed to consider those results in terms of the urban planners.

Transportation system improved with rapid economic growth has helped human being a lot. However, the system has been also created social problems. The fast increasing auto ownership has not only increased transportation accidents but decreased air quality rapidly. One of the serious problems in transportation is that transportation policies have disregarded human factor, especially pedestrian environment. This research has developed microscopic pedestrian simulation with Netlogo. Netlogo is a very useful program for simulating complex systems such as pedestrian movements. The simulated pedestrian movements has been compared with actual surveyed pedestrian movements on a sidewalk. The comparison has been showed that the simulation program can be used for analyzing various pedestrian environments. Also, the impacts of bollard on the sidewalks have been analyed with the simulation program.

This study aims to analyze region-based pedestrian evacuation behaviors and information offering effect using Social Force Model, which is micro simulation. All pedestrians were assumed to move to shelters through pedestrian roads according to guidance information at emergency situations, and the pedestrians were classified into adults and the handicapped. According to the results of the road network analysis and simulation analysis, the shelters to which pedestrians can move within the shortest time from each zone were selected as optimum shelters. From this study, the analysis showed that the information provision effects are informative even though total evacuation time increases due to the increase of pedestrian conflict. This study can be used as baseline data for urban area's pedestrian disaster prevention plans.

교통신호기는 다양한 교통통행에 우선권을 부여하는 교통안전시설물로서, 교통소통과 안전에 지대한 영향을 끼치는 매우 중요한 통제시설이다. 그러나 현행 부적절한 신호기 설치로 차량 교통의 흐름을 방해하거나 교통사고를 증가시키는 경우가 있다. 본 연구는 교통안전시설실무편람에 제세된 9가지 신호기 설치준거 중 보행자 신호기 설치 준거에 대하여 국내도로상황 및 보행자 특성에 맞는 새로운 설치준거를 제시하는데 목적이 있다. 교통운영 측면에서 보면, 보행자 신호기는 보행자가 도로를 횡단하는데 적절한 간격을 찾을 수 없을 때 인위적으로 횡단간격을 만들어 주기 위한 교통제어시설이다. 따라서 보행자가 횡단보도에서 최대로 대기할 수 있는 시간을 기준으로 설치 여부를 결정하는 것으로 가정하고, 보행자가 보도상에서 기다릴 수 있는 최대한도 대기시간은 단일로상의 무신호 횡단보도에 교통신회가 설치되었을 경우 한 주기에서 녹색시간을 감한 시간으로 가정할 수 있다. 무신호 횡단보도 현장조사를 통하여 보행자 횡단행태, 횡단보행속도, 보행자 대기시간 등을 분석하였다. 차량의 간섭에 의한 보행자 회단간격과 차량 교통량과의 관계를 도출하고, 보행자 간섭에 의한 차량 교통량과 보행자 교통량과의 관계를 도출하였다. 결론적으로 차로수별로 차량 교통량과 보행자 교통량 상관관계에 의한 신호기 설치, 설치고려, 미설치 영역을 구분하여 보행자 신호기 설치준거(안)을 제시하였다.

The pedestrian traffic flow has more complicated microscopic features than vehicular traffic flow. Without any designated lanes or any guidance, pedestrians naturally move and change their routes in two dimensional domain with ease. Thus the assessment of pedestrian comfort level should be considering the microscopic features of pedestrian flow. This study is aimed at developing pedestrian comfort criteria based upon pedestrian flow simulation model. This study suggests three criteria to determine pedestrian comfort level; the deviation of route, the acceleration of walk, and the number of collision. Each criterion, which can address the unique walking patterns of pedestrian flow, is represented as each different function with respect to traffic flow rate. The criteria can be the additional indicators to determine the level of service of pedestrian flow together with traffic flow rate and walking speed.

Residential site should have pedestrian road passing through the center of the site just for convenience and safety. However, apartment complexes developed in the past, the sites are just stuck by walls and pedestrian roads are not placed, inhabitans have difficulties for facility use and safety. Therefore, residents solve the problems as follows: they utilize the spaces, between apartment building and the wall, as walking route, and demolish the parts of the wall for connecting sites. In this study, it was thought that pedestrian road could be emplaced at the wall space between sites. For this, a low-rise apartment complex in Gwangju was selected developed in 1990s, and whether the space for pedestrian road was examined. The width from 2.4m to 8.0m could be secured, and there could be placed the pedestrian road at the wall space. However, this study is limited for the possibility of securing space, for the opinion of residents that might be damaged from the pedestrian road did not reviewed.
