The purpose of this study was to analyze the terms used in the Information Boards of Geosites at Jeonbuk West Coast National Geopark. Among the terms used in the Information Boards, nouns were extracted and listed based on the Standard Korean Language Dictionary, a glossary of earth and the data for the development of textbooks according to the 2015 revision of curriculum, by which eight types were classified. Seventy-one nouns (10.8%) of the extracted terms were not listed in any glossary. Most of these terms were compound words derived by combining [noun]+[noun] or [noun]+[affix] so that they were not easy to comprehend. In addition, two hundred fifty-six nouns (46%) of the terms were identified as jargons used in specific disciplines. Therefore, it is strongly suggested that when creating the National Geopark Information Boards, the academic jargon embedded terminologies be explained with annotation for general public visitors and students to understand without difficulty.

Wayfinding is a 'Process solving problem to find destination', and it is important to select spatial data for optimal way. Recently, due to the complexity of space and the expansion of the medium of the wayfinding service, it is necessary to the approach on the information design for them. Therefore, the purpose of this study is to propose a meta guideline on the information design for the design of orientation sign, which is an important cognitive clue in the wayfinding. It was conducted in 3 stages, First, a design process was proposed and design elements were derived for each step by literature research related to information and sign design, and analysis of manual for signage design. Second, a meta guideline for information organization and visualization in the three-stage design process was proposed by FGI and analysis. Third, the meta guideline was applied to the sign design on an area for user evaluation to inspect the applicability of the meta guideline. Through the user questionnaire, the possibility of applying the guideline for visualization of directions and spaces, information hierarchy according to spatial characteristics and information priority was identified. It is meaningful in that necessary element for signage design are systematized centering on the process and that it presents a macroscopic methodology according to spatial characteristics.

This paper presents an active vision system for on-line traffic sign recognition. The system is composed of two cameras, one is equipped with a wide-angle lens and the other with a telephoto lends, and a PC with an image processing board. The system first detects candidates for traffic signs in the wide-angle image using color, intensity, and shape information. For each candidate, the telephoto-camera is directed to its predicted position to capture the candidate in a large size in the image. The recognition algorithm is designed by intensively using built in functions of an off-the-shelf image processing board to realize both easy implementation and fast recognition. The results of on-road experiments show the feasibility of the system.

Recently, there are increasing needs to provide sufficient information on road signs for expanding cities and traffic networks. Improving efficiency of direction guidance information from road signs not only requires criteria for but also systematic approach to selecting place names that appear on road sings. As such, this paper looks at road direction information from existing road signs that leads to Suwon and investigates whether the current system of road sings provides efficient, systematic and continuous direction information for road users to easily reach their destination. In this paper, Suwon's city hall is set up as the final destination, which is linked from five other cities, Euiwang, Ansan, Hwaseong, Osan and Yongin. The paper attempts to find out whether there is continuity and suitable number of road signs for direction information by analyzing the road signs between these 5 cities and Suwon with respect to direction, direction advance notice and direction guidance. It is found that road users cannot easily find the needed information on their destination from the existing road signs and that continuity of selected place names that systematically appear on road signs is insufficiency. That is to say, the findings of the paper are that while it is easy for road users to find place names that are classified under land marks or the first-class selection of place names on road signs, it is difficult to obtain information from road signs on place names that are grouped under the second or third class. In addition, direction guidance on road signs is problematic, because the appearance frequency of road signs is not adequate and the continuity of road signs is not effective. Moreover, there is insufficient information on local direction guidance for immediate destinations on road signs with respect to turning left or right or going straight. Hence road signs in urban area need systematic improvement to find easily some destination.

There are increasing needs to provide sufficient information on road directions through road signs for expanding cities and traffic networks. Improving efficiency of direction guidance information from road signs not only requires criteria for but also systematic approach to selecting place names that appear on road signs. As such, this paper looks at road direction information from existing road signs that leads to Suwon and investigates whether the current system of road signs provides efficient, systematic and continuous direction information for road users to easily reach their destination. In this paper, Suwon's city hall is set up as the final destination, which is linked from five other cities, Anyang, Osan, Ansan, Yongin and Seongnam. The paper attempts to find out whether there is continuity and suitable number of road signs for direction information by analyzing the road signs between these 5 cities and Suwon with respect to direction, direction advance notice and direction guidance. It is found that drivers cannot easily find the needed information on their destination from the existing road signs and that continuity of selected place names that systematically appear on road signs is insufficiency. In addition, direction guidance on road signs is problematic, because the appearance frequency of road signs is not adequate and the continuity of road signs is not effective. Moreover, there is insufficient information on local direction guidance for immediate destinations on road signs with respect to turning left or right or going straight.

도로표지는 도로상에서 도로이용자가 원하는 목적지까지 쉽게 도착할 수 있도록 안내해 주는 기능을 갖는 도로부속물로 꼭 필요한 곳에, 눈에 잘 띄도록, 간단 명료하게 의미가 전달될 수 있도록 설치되어야 한다. MUTCD (Manual On Uniform Traffic Control Devices)의 교통통제설비의 기본요건처럼 무엇보다도 표지판을 보고 필요한 행동을 취하는데 있어서 안전과 시인성이 확보되도록 여유 있게 설치되어야 한다. 그러나, 우리의 표지의 설치 및 운영상황은 그렇지 못하다는 데에서 본 연구는 시작되었다. 시인거리측면을 중심으로 우리나라와 외국 여러 나라의 그것을 비교한 결과, 우리의 규정에서는 판독거리의 중요한 변수인 표지판 정보수가 고려되지 않았음이 드러났다. 따라서, 본고에서는 정보수에 초점을 맞추어 속도와 정보수, 주행 차로 등의 변수를 고려한 표지판 시인거리 측정실험을 하였다. 실험은 현재 국도상에 설치되어 있는 표지판을 대상으로 GPS(Global Positioning System) 수신기를 이용하여 시인거리를 측정하여 진행하였다. 그 결과 실제 시인거리가 현재의 도로표지규정에 의한 시인거리와 다소 차이가 있음을 발견할 수 있었고, 판독거리에서 가장 큰 영향을 미치는 변수는 속도 > 정보수 > 주행차로의 순임을 분석할 수 있었다. 본 연구결과를 통하여 한 개의 물리적 표지내에 정보수가 많은 우리나라의 표지판에 현실적인 시인거리를 고려한 설치가 유도될 수 있을 것으로 기대되고, 향후 도로표지규정을 개정할 때에도 이 연구결과를 반영한 현실적인 규정의 재정립이 기대된다. 또한 표지판의 실제 크기, 글자 및 문안의 크기는 물론 판의 크기 및 여백의 설정도 재산정될 필요가 있으며 이에 대한 추후 연구가 필요하다고 사료된다.

This study proposes a method to quickly and accurately acquire distance information on direction signs. The proposed method is composed of the recognition of the sign, pre-processing to facilitate the acquisition of the road sign distance, and the acquisition of the distance data. The road sign recognition uses color detection including gamma correction in order to mitigate various noise issues. In order to facilitate the acquisition of distance data, this study applied tilt correction using linear factors, and resolution correction using Fourier transform. To acquire the distance data, morphological operation was used to highlight the area, along with labeling and template matching. By acquiring the distance information on the direction sign through such a processes, the proposed system can be output the distance remaining to the next junction. As a result, when the proposed method is applied to system it can process the data in real-time using the fast calculation speed, average speed was shown to be 0.46 second per frame, with accuracy of 0.65 in similarity value.
