Highway classification is an essential part of defining design criteria of roads. This study is to classify highways by factor analysis. To accomplish the objectives, factor analysis is performed for classifying highways using the traffic data observed at the permanent traffic count points in 2004. A total off variables are applied : AADT, K factor, D factor, heavy vehicle proportion, day time traffic volume proportion, peak hour volume proportion, sunday factor, vacation factor and COV(Coefficient of Variation). The results of factor analysis show that variables are divided into two factors, which are the factor related to the fluctuational characteristics of traffic volume and the factor related to heavy vehicle and directional volume characteristics. According to the results of cluster analysis, 353 permanent traffic count points are categorized into such three groups as type I for urban highway, type II for rural highway, type III for recreational highway, respectively.

The origin of Minivan styled RV dates all the way back to the year 1959 when Volkswagen introduced the Microbus in Germany. But the new category of "Minivan" was made, and first used by Chrysler. This was when Chrysler revealed a new vehicle in 1982 named "Minivan". Minivan was successful in gathering the public attention with it′s multi-purpose characteristic. Ever since, many models were introduced in this category by various auto-makers around the world, which made the Minivan segment very competitive. Various Minivans were also introduced by the Korean auto-makers and these models have been finding their place rapidly in the market owing to their unique characteristics. But the reason for the growth of the Minivan category in Korea was quite different from that of other nations. Through out this thesis, the possibilities of a Minivan that can full fill the needs of a new life style of a family in the basis of various documentary records will be discussed. Ways of making roads, where bigger sized Minivans are continuously increasing, more efficient will also be considered. The main topic of this thesis will be about Minivan styled RV(Recreational vehicle) in relation to the change of Korean life style.

This study will analyze the economic impact on villages adjacent to recreational areas in natural forests with the goal of creating a forest development plan. The area of study has been limited to the National Natural Recreation Forest and the twelve adjacent villages around the area. The collected data used a SPSS. 12.0 frequency and cross, t-test and ANOVA analysis was performed. To questions regarding increase in income and employment due to recreational areas in natural forests, there were some in all three areas that responded that it did not contribute to increases in income or employment. In all areas, there were respondents who think that these recreational areas do not help increase awareness of their nearby towns. Facilities, in order from most used to least used were tourist sites, lodgings and then food and meals. The level of satisfaction of customers in all areas was low with reasons being low quality of goods, not knowing the village(s) well, a lack of specialty items, and poor roads. In conclusion, this study presents a development plan based on the derived research results.

The purpose of this paper is to investigate the difference in facilities of natural recreation forests developed by public and private body to answer the research that what is the difference in development of natural recreation forest between public and private developer\ulcorner After reviewing the literatures, developer's decision-making and motivation of investment, and the planning process of natural recreation forest, we had constructed th conceptual framework and have found the hypothesis of this research. Using data on development status of natural recreation forests and questionnaire surveying of 625 visitors from 9 among 72 natural recreation forests in Korea, We analyzed the data through the comparison of quantity of facilities per 1000 visitors and logistic regression method for quality of facilities. We have found that 1) the six facilities have been turned out to be statistically significant in determining the difference of public and private recreation forests. i.e., infrastructure including roads, maintenance and information and lodging and evacuation, indoor education, outdoor education, and shopping, 2) public recreation forests are well equipped such basic facility as roads, maintenance and information, lodging and evacuation while private recreation forests are well equipped such facility as indoor education, outdoor education, and shopping, and 3) the importance of such facility as roads, maintenance and information, lodging and evacuation, outdoor education, and shopping have been turned out to have 1.99, 2.26, 1.99, 3.01 and 2.24 times more important than that of indoor education, respectively. We can conclude that public recreation forest seems to be equipped with the facilities for sound recreational opportunities for general public, and private recreation forest turned out to have more facilities for pursuit of profits, installed basic facilities for user convenience and service, and special facilities for attracting user and raising revenue. Using the results of this research, we can make a guideline for a market positioning, and standards and provisions of natural recreation forests. We suggest that the relationship between user-satisfaction and recreation facility is needed to be examined in the future research.

This study examined the impact of COVID-19 on traffic demand (Average Daily Traffic : ADT) by analyzing the available data on highway traffic volume and the spread of COVID-19 cases in Korea. This study used the data from 228 permanent traffic counts (PTCs) on highways from January to May of 2019 and 2020 to analyze the change in ADT. The first cases of infection in Korea occurred on January 20, 2020, and the maximum daily number of infections was 909 on February 29. On April 30, 2020, the daily number of infections decreased to four. The ADT decreased by 3.3% due to the impact of COVID-19. Considering that the traffic volume has increased 2.3% annually over the past decade, the actual decrease in ADT due to the COVID-19 is estimated to be 5.6% (3.3% + 2.3%). The ADT for weekends decreased significantly, compared to during the week. An analysis of the changes in ADT according to the road type revealed decreases in the following: urban roads -4.6%, rural roads -3.2%, and recreational roads -0.7%. Urban roads decreased the most, and tourist roads decreased the least.

Road classification system is the first step for determining the road function and design standards. Currently, roads are classified by various indices such as road location and function. In this study, we classify road using various traffic indices as well as to identify traffic characteristics for each type of road. To accomplish the objectives, mixture model was applied for classifying road and analyzing traffic characteristics using traffic data that observed at permanent traffic count stations. A total of 8 variables were applied: annual average daily traffic(AADT), $K_{30}$ coefficient, heavy vehicle proportion, day volume proportion, peak hour volume proportion, sunday coefficient, vacation coefficient, and coefficient of variation(COV). A total of 350 permanent traffic count points were categorized into three groups : Group I (Urban road), Group II (Rural road), and Group III (Recreational road). AADT were 30,000 for urban, 16,000 for rural, and 5,000 for recreational road. Group III was typical recreational road showing higher average daily traffic volume during Sunday and vacational periods. Group I showed AM peak and PM peak, while group II and group III did not show AM peak and PM peak.

This research is to analyze the spatial organization of a traditional rural community and its characteristics, the case of Hanbam village located in the north of Daegu city. The conclusions of this study are as follows; 1. The difference between private space and public space in the residential area of Hanbam village is obvious, and these two spaces are organically related each other by means of road. These spaces have some spatial characteristics of organization, such as center, hierarchy and sequence. 2. The private space consists of a residence module and a farming area in the settlement, and it is clearly farmed by the firm fence of rocks and by surrounding roads. Fruit-bearing trees such as Pyrus pyrifolia, Cornus officinalis, Diospyros kaki, Juglans sinensis are planted at the boundary. And most of residences are composed of a building, a inner court and farming fields. 3. The public space for the community mainly functions as ‘a meeting place’for residents, and consists of recreational spaces, ceremonial spaces, community facilities, and social facilities. Among these, Jeong-ja(pavilion), Seong-an Soop(forest) and Dae-chong(building for common use) are of great cultural value as important traditional spaces. 4. Two kinds of road are commonly fecund in the village; spontaneously generated one and planned one. This is straight inner streets and access paths to the village, and that is curvilinear alleys which are connected to Dae-chong, the core of village. Also stone walls and climbing plants on them are major elements of village landscape.

Forest road has been an essential infrastructure for various forestry practices as well as for recreational use, disaster management, and local economics promotion. Since 1980s, extensive network of forest roads has been constructed as an national project in Korea. However, due to the minimal-budget of the project, accurate maps of forest road are not usually available. Although forest road map is a main thematic layer for the forest Geographic Information System (FGIS), its locational accuracy has not been sufficient for the practical applications and, therefore, the update of digital forest road maps is urgent. The objectives of this study is to compare ae methodology of generating and updating digital forest road maps from the aspects of the map accuracy and the efficiency of methods. Four mapping methods (GPS surveying, satellite imagery, ortho aerial photograph, and digital photogrammetry) were applied to generate the forest road maps over the study area of Mt. Oseo in Chungchungnam-do, which has a 35km forest roads distributed in national, public and private forests. The forest road Imp produced by digital photogrammetric method is the most accurate and comparable to GPS surveying although it required the greatest amount of labor time.

The Seomoon Bridge, a new planning site, is located in Sangdang-Gu Seomoon-Dong, Chongju and is the oldest bridge built during the rule of Japanese imperialism. As the name implies, Seomoon Bridge is located on the site adjacent to west gate. The Seomoon Bridge is an important bridge as an historical trace of the vanished town of Chongu. However, as new roads and bridges are built, the Seomoon Bridge is losing its functional aspects and has become an area crowed by many street stalls. Closely located newer to Sajic Fountain, the Seomoon Bridge, which has symbolically significant meaning, now faces many problems such as non-practical use of bridge, indifferent management and non-locality, which creates a negative effect on the surrounding cityscape. given this situation, in 2001, 2, Chongju city published an appeal for public subscription of a practical use plan which may design a new, landmark and establish resting spaces for the public. The basic direction of this planning is designed to be place as the symbolic space representing Chongju, and integrated with the surrounding environmental elements such as Moosim-Cheon(stream) and Sajic Fountain, and as a recreational, resting and leisure space of the public. Especially nightscape of the bridge inspires a fresh impact on many people. Because of the widespread influence of developed cities, diverse spaces which already exist or have disappeared may be reclaimed. By establishing appropriate use plans rather than negligence, this project will propose the improved quality of cityscape and show the possibility of bublic´s outdoor living space, and our team will find out the meaning in these approach methods.
