Intelligent Transportation Systems (ITS) are advanced applications which, without embodying intelligence as such, aim to provide innovative services relating to different modes of transport and traffic management and enable various users to be better informed and make safer, more coordinated, and 'smarter' use of transport networks. However, ITS has the different size and shapes according to the city environment policy to adjust the city scene and it has to be displayed by different message on the information display device in real-time. And the information service providers must make the information display system which has the different information and data each time. That is very time and workers consuming and auto message frame generation system is necessary. In this paper, we design and develop the message frame generation system which can set several parameters easily for the generation of the message frame automatically on the windows environment and we do not need to go the field to get the test data.

This study is intended to examine the characteristics of driver in the use of guide sign in urban areas. The good and bad points about guide sign based on landmark point and guide sign based on street name are demonstrated, and driver's preference between them are studied. The questionnaires given to general persons deal with general guide signs and road maps, and are designed to see if they can find out current location on the road map with guide sign. According to the results, drivers prefer guide sign based on street name to guide sign based on landmark. And guide sign based on street name took less time to find current location than with guide sign based on landmark.

One of the crucial elements to fully facilitate the various benefits of intelligent transportation systems (ITS) is to obtain more reliable traffic monitoring in real time. To date, point and section-based traffic measurements have been available through existing surveillance technologies, such as loops and automatic vehicle identification (AVI) systems. However, seamless and more reliable traffic data are required for more effective traffic information provision and operations. Technology advancements including vehicle tracking and wireless communication enable the acceleration of the availability of individual vehicle travel information. This study presents a UBIquitous PRObe vehicle Surveillance System (UBIPROSS) using vehicle-to-vehicle (V2V) wireless communications. Seamless vehicle travel information, including origin-destination information, speed, travel times, and other data, can be obtained by the proposed UBIPROSS. A set of parameters associated with functional requirements of the UBIPROSS, which include the market penetration rate (MPR) of equipped vehicles, V2V communication range, and travel time update interval, are investigated by a Monte Carlo simulation- (MCS) based evaluation framework. In addition, this paper describes prototypical implementation. Field test results and identified technical issues are also discussed. It is expected that the proposed system would be an invaluable precursor to develop a next-generation traffic surveillance system.

교통소통과 안전을 위해서는 체계적이고도 획일적인 교통안전시설물의 설치 및 관리가 요구된다. 앞으로 교통안전시설물에 많은 투자가 절실히 요구되며, 계속 늘어나고 있는 자동차등 여러 가지 교통여건을 감안하면, 교통안전시설물에 대한 수요는 더욱 증갛살 것으로 예상된다. 지리정보시스템 (GIS)을 활용하게되면 급증하는 교통안전시설물의 조사 및 유지·관리업무를 제한된 인력과 예산으로 수행할 수 있게된다. 그러므로 교통안전시설물의 체계적인 유지·관리를 위해선 GIS의 활용은 필수적이라 하겠다. 또한 신설 및 교체수량의 정확한 예측 등과 같은 효과를 거둘 수 있어 효율적인 예산을 집행할 수 있게된다. 본 연구는 지리정보시스템 (GIS)을 이용하여 교통안전시설물 유지·관리 시스템 개발에 목적이 있으며, 특히 개발된 시스템은 실무담당자 활용에 편의를 도모하는데 주안점을 두었다.

최근 자동차 연구개발에 있어 내연기관을 대체하는 친환경 자동차기술과 더불어 무인자동차, 자율주행기술이 많은 부분에서 시도되고 실현되어가고 있다. 지능형 자동차라는 개념에서 적용되었던 운전자안전보조시스템, 편의지원과 사고경감 시스템 등이 하나로 통합되어 무인자동차 기술로 발전하고 있다. 또 차량에 고가의 센서를 장착하여 주변환경이나 운전자를 모니터링하는 방식에서 IT 융합기술을 이용한 네트워크기술 (V2I, V2V, V2N & V2X)을 접목시키는 방안을 통하여 개개의 차량은 물론 교통체계의 전체적인 변화를 추구하고 있다. 이러한 첨단차량기술은 새로운 교통문화(차량공유시스템, 군집주행)의 개발과 또다른 교통체계의 연구로 확장되어가고 있다.

This study dealt with Traffic Problem to Cheonan city. This study ran parallel literature investigation and actual proof investigation. Questionnaires 394 enforce frequency analysis in SPSS 15.0 versions. Traffic Problem to Cheonan city include the discomfort of public transportation, parking problem, pollution of automobile, traffic accident. By improvement of traffic problem, first, improvement plan of transportation system by administration of logical traffic demand should be readied. Second, because Cheonan city is many an university student who is use target of public transportation, public transportation utilization ratio must raise through discount application. Third, solution of traffic jam need to the improvement and strengthening of system of public transit. Fourth, Cheonan city must push ahead with supplies of traffic facility, modify of transportation network, and improvement of operating system. In particular, Cheonan city need to modify old road and improvement of accessibility though road network briefly. Fifth, Cheonan city need fixing of van traffic culture such as solution of parking problem and traffic order consciousness fostering of users.
