보행은 사람들의 건강을 증진시키고 증가하는 교통 체증 해소에 중요한 역할을 한다. 기존 보행관련 연구는 유럽, 북미, 동아시아 등에서 진행하였으나, 베트남과 같은 덥고 습한 개발도상국 도시들의 경우, 걷기에 대한 연구가 비교적 많지않다. 따라서 본 연구는 베트남 호치민시 중심지구의 보행편의성과 건축 환경이 보행에 미치는 영향에 대하여 연구를 진행하였다. 본 연구는 대상지를 이용하는 사람들의 보행 빈도와 건축 환경 사이의 상관관계를 분석하고 있다. 기존 선행 연구에서 일반적으로 사용된 요소 외에도, 본 논문은 보행편의성 지수를 추정하기 위해 도시의 다른 특정한 건축 환경 요소를 사용하였다. 사용된 지표는 주거 밀도, 상업 비율, 혼합 토지이용, 교차로 간격, 블록 크기, 보행로 비율, 천장 유무, 온도 9가지를 사용하였으며, 이러한 지표는 지역 주민들을 대상으로 실시한 조사와 비교 분석을 실시하였다. 분석 결과 사람들은 보행편의성 지수가 높은 지역에서 더 많은 보행을 하는 것으로 분석되었다.

Walking plays an important role in promoting peoples' health and reducing the increasing pressure of traffic congestion. However, for cities in developing countries located in areas with unfavorable weather, such as hot and humid weather, there is not much research on walking. Therefore, this study focuses on the walkability and the effect of the built environment on walking in the center district of Ho Chi Minh City, Vietnam. The correlation between the built environment and walking frequency of people was analyzed. Besides common elements that have been used in previous studies, other specific factors of the built environment were determined to estimate the walkability index. The results were then compared with the amount of walking obtained from surveys of local people. The result shows that people tend to walk more in the areas with a higher walkability index.

문제 정의
Firstly, as shown at the “Walkability index” section, we asked about the level of agreement on the effects of each factor on their walking choice. The purpose is to determine the impact factors. The second section asks about people walking frequency to compare and verify the accuracy of the walkability index calculation.
For that reason, finding the factors that are needed for walking encouragement is essential. This paper focuses on both object and subject research. The research purpose is to search for effecting factors and digitize them through the z-score to estimate the walkability index of each neighborhood in District 1 (object).
Because of the distinction of the climate, city structure and even the culture and people’s habits; the walking condition in this city is different from it in the other cities. This paper follows the theoretical foundations of previous studies, but takes into account some other specific elements that are expected to contribute to the number of walking decisions of local people in the city center. Hypotheses about the effect on the walkability of those factors are analyzed to prove the authenticity.
제안 방법
Nonetheless, as a matter of course, the research also has limitations. Firstly, because of the lack of data, the paper cannot analyze the neighborhoods in more detail with a smaller scale, but simply analyzes based on the administrative boundaries and functional subdivision of the city. Secondly, the values of walkability index and realistic walking frequency do not exactly match.
The diversity of land use plays an important role in promoting the walking [12]. For this study, the land use is classified into five categories, including: residential, retail, entertainment, institutional and others.
To have the database, the survey is conducted on 138 people in the study areas. The questionnaire asks people about the frequency of walking for each trip purpose every week. The result shows that people living in the neighborhood 2 are “the laziest” to walk, with an average of just 5.
This paper focuses on both object and subject research. The research purpose is to search for effecting factors and digitize them through the z-score to estimate the walkability index of each neighborhood in District 1 (object). Walkability reflects how pedestrian-friendly of an area.
대상 데이터
District 1 includes 10 wards. However, because of the unique features of functional subdivision and urban structure, one of these areas is divided into two separate study areas (area 8 and area 9 in Figure 3 and Figure 4).
District 1 is the central district of Ho Chi Minh City with an area of 7.73 km2, which is home to 193.632 people [16] (Figure 2). District 1 is considered as one of the highest living standards district of the City in all aspects.
To investigate the walking frequency of local people, the survey is conducted on 138 people living and working in 11 areas of District 1, Ho Chi Minh City. The respondents include 51.65% of women and 48.44% of men and the average age of the interviewees is 27.34. The walking purpose is divided into 4 main categories: walking to shopping, walking to public transport, walking to school/work and fitness walking.
To have the database, the survey is conducted on 138 people in the study areas. The questionnaire asks people about the frequency of walking for each trip purpose every week.
Walking frequency is a practical reflection of the frequent or non-frequent walking of people in the study area. To investigate the walking frequency of local people, the survey is conducted on 138 people living and working in 11 areas of District 1, Ho Chi Minh City. The respondents include 51.
이론/모형
As such, there are seven factors that are expected to affect walkability in the research area_District 1. To determine which elements affect the walkability, the authors analyze these eight factors by the EFA method. 138 people who live and work in District 1 were asked about the level of consent for the impact of each given factor on their walkability.
성능/효과
The comparison between walkability index and walking frequency is shown in Table 2. From the relative coincidence of the calculated walkability index and the actual walking frequency from local people, it can be concluded that the walkability index built in this study is quite accurate and reliable.
후속연구
In the other words, the walkability index calculation simply is the sum up the factor index (z-scores) without taking into account the exact coefficient of each factor. Further researches, perhaps should base on more factors with the coefficient of each element to achieve the accuracy. Moreover, in the case of Vietnam, door-to-door traffic using a motorcycle is common.
It is considered to influence the selection of the means of passage depending on the purpose of the trip. Therefore, the next studies should further investigate the relationship between the walking frequency for each purpose and the walkability index beside the summed traffic frequency for a more detailed assessment.
