The purpose of this study is to observe the effects of road facilities that have adopted digital media such as total road facility called L.E.D media pole installed on U-street, Gangnam-gu on the pedestrians' satisfaction. Through the study, we would like to improve the brand competitiveness, increase the revisiting decision factors and suggest the fundamental development direction for the digital media road facilities on the typical pedestrian road, Gangnam street. The three factors from the studies came out to be spatial component, design component, and functional component. In order to analyze the factors, the pedestrians' behaviors were observed through a direct survey which provided 35 reserved factors. Also, the preliminary factors derived through survey questionnaires were revised by experts which compressed the result into 20 factors. The result of the regression analisis states that the 'Factor of the spatial component' is the statistically significant factor among the five elicited factors of the effect of the media pole on the pedestrian satisfaction. U-street's media pole provides the comfortable and various contents and application methods and will provide the new perspective on the purpose of pedestrians by new experience that is based on digital technology.

In Korea, local governments have decided the location of shelters as part of their disaster planning. However, no quantitative standards, such as assuming different hazard and shelter types, shelters' capacity, are specified in that planning. To propose the direction of disaster evacuation policy, first of all, the current state of shelters' location and evacuation area is needed to be analyzed. In addition, considering topographical condition such as road slope and physical strength by age are important factors to measure optimal evacuation route. The purpose is to suggest a new methodology of estimating optimal evacuation route considering resistance of road slope and difference of walking speed by age. Moreover, as a case study of Seoul, Korea, using coverage analysis of GIS analysis tool, the accessible area (or vulnerable area) to the shelters is evaluated based on the spatial distribution of disaster evacuation shelters and their accommodation capacity, according to evacuation time within 7.5, 15 and 30 minutes. The main results are summarized as follows: 1) The average area of disaster evacuation shelter per person is calculated as 0.45 square meters. Considering that the minimum shelters' area per person is 1 square meters, only 45% of people in Seoul can be accommodated. 2) The ratio of inhabitants who live in accessible area within 7.5 minutes presents only 33% of all. Furthermore, the ratio of inhabitants by age group of 5~9 or over 65 years old shows significantly lower percentage in comparison with 15~49 years old people.

This study was carried out to select proper species fur early stage replantation in forest road cut-slope. From one to fifteen years elapsed forest roads in four regional areas of Gyeongsangnam-do and Jeollanam-do, sample plots were selected, and their vegetations and environmental factors were investigated. Invaded species and plant coverage have increased with elapsed years. The occurrence rate of herbs have decreased, while the occurrence of trees have increased with elapsed years. The ordination analysis showed that distribution of species was influenced by the elapsed year, the slope angle of the cut-slope, elevation, and the direction angle of the cut-slope. Dactylis glomerata, Poa pratensis, Amorpha fruticosa, Lespedeza sp., Artemisia princeps var. orientalis, Duchesnea chrysantha, Miscanthus sinensis, Pueraria thunbergiana, Zanthoxylum schinifolium, Rhus chinensis, and Weigela subsessilis were considered as proper species for replantation in forest road cut-slope, besides the species used already. Seventy seven family, 190 genus, 233 species, 38 variety, and 271 species in total were counted as invaded plant species in the survey zone. Naturalized plants were 18 species. Invaded species are, with high frequency first, Rubus crataegifolius, Artemisia princeps var. orientalis, Zanthoxylum schinifolium, Pueraria thunbergiana, Pinus densiflora, Lespedeza maximowiczii, Lysimachia clethroides, Lespedeza bicolor, Youngia denticulata, Miscanthus sinensis, and Erigeron annuus.

This study aimed to identify the optimal street tree planting method to improve the summer thermal environment in Seoul, Republic of Korea. The effects of road direction and street tree planting patterns on urban thermal environments using ENVI-met simulations were analyzed. The 68 scenarios were analyzed based on four road directions and 17 planting patterns. The results showed that tree planting had a reducing air temperature, mean radiant temperature, human thermal sensation (PET and UTCI). The most effective planting pattern among all scenarios was low tree height (6m), wide crown width (9m), high leaf area index (3.0), and narrow planting interval (8m). The largest improvement in the thermal environment was the northern sidewalk of the east-west road. Since this study used computer simulations, the difference from real urban spaces should be considered, and further research is needed through field measurement and consideration of more variables.

It is called vehicle pull when a vehicle drifts in the lateral direction under the straight-ahead motion with no steering or external input. Recently vehicle pull draws attention as one of the critical evaluation items from the customers on the vehicle quality. It is generally recognized that the vehicle pull is complex phenomena due to internal and external factors. In this paper the relations between vehicle pull and ire were investigated through close survey on the road test results from the final inspection of car manufactures. Through this investigation the factors are identified which play an important role in causing vehicle pull problem.

Measurements of accelerometer levels transmitted from the floor in commercials truck shipments were carried out transportation of 300 Kg-load from Gyungbu Highway(Waegouan-Seoul) to 88 Highway(Gwangju-Daegu). Different characteristics were observed the values measured the vibration levels with directions in the two Highway's as a function of road condition and truck speed. The results showed that the vibration levels of the Gyungbu Highway is much higher than those of the 88 Highway. A following analysis on the obtained values was used to get the acceleration spectral density (ASD) and power spectral density (PSD). For the entire transit route, the results showed that the level of vibration to vertical direction was significant effects for damaging the products carried compared to other directions such as longitudinal and transverse. This paper provides an updated history of measured characteristics of vibration levels for highways using mainly in domestic area.
