The use of existing macroscopic research of pedestrian behavior on the walking link as data is limited in determining an individual pedestrian's moving route and the level of service. In macroscopic studies, it is difficult to make quantitative indices, such as pedestrian flow rate, occupied space, density, and speed for determining the level of service on pedestrian roads. Therefore, the microscopic pedestrian route is required to establish appropriate pedestrian policies. In this study, the Yeok-Sam subway station network was examined using a micro-simulation VISSIM, which was then calibrated and validated statistically. The Pedestrian Road's Level of Service of Yeok-Sam subway station area was evaluated using the pedestrian speed as the evaluating index on the Korean highway capacity handbook.

The main reason to install pedestrian pushbuttons is improving traffic operations. The current guideline for the installation of signal systems with pedestrian pushbuttons is car-oriented. It is difficult to clearly understand the guideline because there isn't an in-depth study to compare the pros and cons of the pedestrian- and vehicle-oriented methods in terms of waiting time. Thus, this study aims to estimate the waiting times of pedestrians and vehicles. The two delay times are compared considering the hypothetical circumstances such as geometry, pedestrian crossing time, pedestrian/vehicle counts and arrival distribution. The results show that when the pedestrian traffic volume exceeds 97 ped/h in the case of a two-lane road (one lane in each direction) the pushbutton system is effective and beneficial to pedestrians. It means that the total waiting time of pedestrians is less than the one of vehicles. Additional four scenarios are designed and tested by varying the number of lanes and design speeds. In conclusion, the pushbutton signal is more beneficial for pedestrians when the number of pedestrians is less than or equal to 85, 70, and 70 ped/h for the three-lane scenario, the four-lane with the design speed of 80km/h scenario, and the four-lane with the design speed of 100km/h, respectively.

As car-oriented road policies have been made forward so far, relatively pedestrians' walking conditions are so in poor environments that more than two thousand pedestrians die from car accidents every year. Pedestrians' walking right has been severely invaded like that. Pedestrians' walking right is a right that people are able to walk safely and comfortably in pleasant surroundings as long as they don't threaten the public safety, order maintenance, and welfare. The government has an obligation to provide safe, comfortable, and pleasant environments to pedestrians. Recently interests in pedestrians' safety are increasing, government-driven supports have been made to make safe, pleasant, and healthy walking surroundings. As poor walking condition improvement projects cost high, they should be progressed to accomplish maximal effects using finite finances efficiently, and post feasibility evaluations of the projects should be severely estimated. However site selecting indicators which satisfy with the goal for composing safe working surroundings have not been decided yet, though currently it has a legal basis to specify walking condition improvement sites by the Law for Pedestrians' safety and Comfort Increasement. Therefore this study focuses on suggesting improved ways for selecting sites where pedestrians' safe environment project by reviewing previous research. When project sites are selected, evaluation indicators related to awareness survey of residents and history should be excluded, and disaster safety assessments for walking safety facilities, latent human hazards and natural disasters like a strong wind are proposed besides evaluations on pedestrians' safety and walking environment for matching with the purpose of the project to make safe working surroundings.

A new urban paradigm that moves from a vehicle-centric to pedestrian-centric culture should be considered to improve the quality of the pedestrian environments for women, children, senior citizens, and disabled persons as well as to promote community unification by providing general movement rights to everyone. This study was implemented to provide decent alternatives to improve street spaces. The street spaces around the Commercial and Residential Area No.1 located in the Administrative-Centered City, Sejong Special Autonomic City, were selected to analyze and define the status of the walkways and the street spaces. Satellite imagery and numerical maps were used to collect geographic data. Practical and actual surveys for the selected sites were performed to analyze the street status and the pedestrian status. Based on the all collected data, analysis results, and literature reviews, the questionnaire was made, and 315 inquiries qualified for analysis. The physical status of all four study sites was the highest level, Grade A, and green open spaces were relatively sufficient. As a result, the factors obtained from the factor analysis have an impact on the satisfaction of the pedestrian streets in the commercial area. The factors are as followed Design > Convenience > Roadside trees and rest areas > Safety > Safety protective facilities > Transportation and information facilities > Continuity > Basic state of road surfaces > Comfortability, and in the residential area: Transportation and information facilities > Basic state of road surfaces > Comfort > Convenience > Continuity > Design > Illumination and crime prevention facilities > Safety > Roadside trees and rest areas.

In Korea, the importance of walking has not been stood out in relief because of the rapid increase of a car on a drastic economic growth in the past half a century. Walking has failed to be recognized as a traffic measure or one of basic human rights. Therefore this study brings up problems of weakened walking right from increase of cars and examines reinforcing policies for walking right of advanced countries. And this study presents institutional devices for introducing walking safety measures of advanced countries reflecting pedestrian satisfaction and opinions about walking right. The results of this study are, First, pedestrians' walking liberty is guaranteed, Second, how to repair walking environment is searched and practical measures are analyzed to find out what is applicable to Korea, can reduce pedestrian accidents and is wanted by pedestrians using GAP analysis and Structural Equation. Third, basic data for upcoming selection of policies are presented by analyzing pedestrian satisfaction assuming that selected measures are operated.

Rapid urbanization causes a variety of transportation problems, including traffic delay. Then transportation engineers would get involved in trying to solve traffic delay through road constructed and uncongested policy. But lately, traffic policy changed from vehicle-dominated to humandominated and green transportation. Road diet is one of green transportation. Road diets reduce the number of lanes, lane width because supplement space for green transportation including a bicycle road, side-walk, etc. A study on road diets not enough then this study performed a basic study for road diets. This study on lane width reduce for road diets through analyzes sway of moving vehicle. This study results shows lane width of a compacts-size car needs 2.34~2.70m and lane width of a full-size car needs 2.62~2.89m. According to this study lane width can reduce therefore lane width design criterion have to be relieved. This study will be used in a road width reduce including a road diets, road in process of construction and so on.

Nowadays, the Korean society is full of multiculturalism as there are many foreign ethnic enclaves. Many Chinese quarters are built in various parts of Korea along with the increasing population of Chinese immigrant. Especially, the Chinese quarter has shown the sign of time and the cultural characteristic of the local residents. This research is to study the market space of Chinese ethnic enclaves in Dairimdong. This research method is the field study to use a participant observation. Below are the research results: Chinese merchants put a private object such as "tanzi" on a sidewalk and install large awning covered full of sidewalk. Sidewalk transform from an outdoor space into an internal space because of Chinese merchants. Passers-by move to use vehicle roads and transform not only the car's space but also the passers-by space. Urban planners originally classify space into three categories, which are building - sidewalk - vehicles road. However, after Chinese came to the market, Chinese classified space into new three categories which is building - space for both sidewalk and "tanzi" - space for both sidewalk and vehicles road. New classification of space is quite different from the previous. In addition, Chinese thinks that the Dairimdong's Market is a very comfortable place. Because Dairimdong Market have many Chinese physical facilities. Next, Chinese thinks that the Dairimdong Market is a very friendly place to buy Chinese products easily. This market has become a place of consumption for the Chinese. Eventually, Dairimdong's Market has changed because of Chinese immigrants. It is possible to make satisfactory planning and design proposal to build Chinese quarters in the future through the explanation of space and status by way of culture. There are many careless mistakes in previous subjective planning and design proposal of the designers. Thus, it should consider the problems created by their way of use in later planning and design.

위치기반서비스(Location Based Service)는 갈수록 고도화 되어 가고 있다. 특히 최근의 대형 포털을 중심으로 지오웹 서비스가 활성화 되어 있고 이를 스마트폰과 같은 개인용 이용기기를 통해 연속적으로 제공하려는 경향이 뚜렷하다. 이와 같은 시점에서 정부와 민간에서 구축 중이거나 보유 중인 전국적 규모의 데이터 간 상호 연동과 융합을 도모하려는 시도 또한 불가결하다. 이는 고도화된 LBS를 위하여 반드시 필요한 과정이기 때문이다. 이에 따라 몇 가지 주요한 전국 데이터를 대상으로 상호 연동과 융합을 위한 기술개발을 시도하였다. 우선 도로명주소기본도와 수치지형도 간 POI의 연계를 위한 연구를 수행하고 있다. 이 연구에서는 두도면 내의 POI를 대상으로 다양한 매칭과 이에 기반 한 의사결정 방법론을 이용하여 자동으로 상호 인식 및 연계가 될 수 있도록 하고 있다. 다음으로 지적도와 수치지형도 간의 객체 매칭에 관한 연구이다. 수치지형도와 지적도의 불부합으로 인하여 그 동안 지적도를 수치지형도에 맞춘 형태의 편집지적도를 지속적으로 생산하여 왔고 앞으로도 그럴 것이다. 문제는 여기에 필요한 많은 예산이다. 만일 수치지형도와 지적도를 자동으로 매칭하여 편집지적도를 자동으로 생산할 수 있게 된다면 많은 예산 절감과 함께 편집지적도의 현시성을 확보할 수 있게 될 것이다. 다음으로 항공사진과 도로망도의 매칭이다. 현재 주요 포털에서 제공하고 있는 항공사진 기반의 도로망도는 기복변위와 같은 문제로 인하여 시각적으로 많은 위치오차를 보이고 있다. 만일 항공사진의 도로영역을 자동으로 추출하여 벡터 도로망도와 매칭을 할 수 있다면 보다 시각적으로 안정된 항공사진 상의 도로망도를 제공할 수 있게 되고 나아가 이는 차량이나 보행자 네비게이션에 매우 요긴하게 이용될 수 있을 것이다. 다음으로 서로 LOD가 다른 도로망도의 매칭 문제이다. 많은 기관에서 독자적으로 생산한 도로망도는 LOD의 상이에 기인한 문제가 많아 서로 연계 활용되지 않는다. 이를 자동으로 매칭하여 서로 연계할 수 있다면 두 도로망도가 보유하고 있는 속성정보를 공동으로 이용할 수 있는 이익을 얻게 된다. 다음으로 지도 일반화 기술이다. 지도일반화는 지적도내 수치지형도와 같은 대규모 데이터를 스마트폰과 같은 저용량 사양의 기기에 서비스 할 때 불가결한 기술이다. 지도상 객체들의 기하학적 정보 손실을 최소화하면서 메모리 측면에서 경량의 지도를 자동으로 만들어 낸다면 이는 매우 요긴하게 이용될 것이다. 마지막으로 보행자 네트워크의 생성기술이다. 보행자 네트워크는 그 상세함과 정보용량에 있어서 차량용 네트워크에 견줄 수 없다. 이를 현행의 차량용 네트워크와 같이 수동으로 생성하는 데에는 경제적으로나 시간적으로 막대한 투자가 필요하다. 따라서 이를 기존의 공간정보들을 활용하여 자동으로 생성해 낼 수 있다면 그 파급효과는 매우 크리라 판단된다. 본 발표에서는 위와 같은 주제에 관하여 그간의 연구 성과를 개략적으로 소개해본다.

Walking is basic and important means of transportation for human. Although recently safety for pedestrians relating to traffic safety is considered to be important, efforts and interest for pedestrian safety are very unsatisfactory. Thus, it is needed to develop a pedestrian safety index which could be used to plan pedestrian safety program and to reduce/prevent pedestrian accidents. In this study, the Pedestrian Safety Index about 10 cities in Gyeongnam Province was developed using 5 factors highly influencing on pedestrian safety, which are the five year average pedestrian accidents per 100,000 population, the year 2009 pedestrian accidents per 100,000 population, crosswalk signal obey rate, jaywalking rate, and the year 2009 pedestrian accidents for children under 14 years and the elderly over 65 years. The perfect score for the index is 100. As the score becomes nearer to 100, pedestrian safety becomes better. The pedestrin safeties of Changwon, Gimhae and Masan are good and those of Sachon and Tongyong are bad. Tongyong's low score at the index is due to high pedestrian accidents rate only and Sachon's low score is due to high pedestrian accidents rate and jaywalking. At the pedestrian safety index of 10 counties of Gyeongnam Province, the pedestran safeties of Hamyang and Hapchon are good and those of Haman, Hadong and Gosung are bad.
