As ICT technology develops, researches on the construction of communication system for the rapid processing using ICT technology in case of traffic accidents are actively under way. e-Call (Emergency call) is a vehicle ICT-based emergency rescue system that recognizes and reports traffic accidents. On the other hand, the existing bus information system collects the positioning data through the position tracking system mounted on the bus and transmits it to the center, and then provides various services based on the bus information of the collected buses. In this paper, we designed and implemented an emergency rescue system that using the existing bus information system in order to deal with accidents, failures, and emergency situations on public buses quickly.

Vehicular communications can be applied for transmission of various safety messages or Intelligent Transportation Systems(ITS) applications by combining vehicle/road technology with Information and Communication Technology(ICT). In this paper, we represent measurement results of radio characteristics of vehicular communications using IEEE 802.11p based system in urban environments. Radio characteristics are based on the packet error rate (PER) and received spectrum mask. Using measurement results, we discuss implementation issues of vehicular communication systems for supporting reliable services.

Artificial Intelligence is one of the technologies that are being discussed in the Fourth Industrial Revolution, attracting the attention from companies around the world and this technology is being applied to various industries such as education, finance, automobile, etc. AI integrated ChatBot is a system designed to respond to user questions according to defined response rules. This system is gradually expanded from simple inquiry responses for intelligent virtual assistant service, weather, traffic, schedule, etc. to service provisions through user pattern analysis, to solidify its position as a life-style service. As a result, research on AI integrated ChatBot platform has become necessary. Therefore, this study suggests the design and implementation of an intelligent chatbot service platform for small businesses.

As one of the most serious urban problems, routine city traffic congestion causes not only unpleasantness but also damage with increases of road tolls. Recently, many TDM plans are being improved along with plans to more effectively utilize established facilities and maximize the effect. To achieve the purpose of Intelligent Transport Systems(ITS). Recently, the core of ITS is Advanced Traveler information Systems (ATIS.) that are activity researched. A development of various muti-media system is very important of road guideline. First of all a business processing for offering travel information and give a consideration to the United states of various muti-media systems.

eCall system assists traffic accident victims by connecting emergency rescue institutions with accurate accident information, helping them to identify the on-site situation in the event of a traffic accident. The purpose of this paper is to develop a Korean eCall system that reflects the requirements of domestic emergency rescue institutions and to analyze the expected effects through an integrated demonstration. The results of an integrated demonstration indicated that the communication success rate between the eCall IVS and the call center was 99.25%, and the average location information error was 1.2 m. In particular, it has been confirmed that the average location information error is less than 21.6 meters, as assessed by the Korea Communications Commission when evaluating the accuracy of domestic emergency rescue location information. When the eCall system was introduced, it was confirmed that the time from traffic accidents to hospital arrival could be shortened by 3 m 38 s for highways and 1 m 22 s for general roads. By it to traffic deaths from 2005 to 2022, it was analyzed that the number of fatalities decreased by 82,662, resulting in a reduction of approximately social costs.

본 논문에서는 Radio Frequency Identification(RFID)를 이용하여 도로의 Internet of Things(IoT)를 실현하는 기술을 구상한다. RFID태그를 도로에 일정한 간격으로 설치하고, 자동차에 설치된 RFID 리더기가 태그에서 정보를 읽고 실시간으로 중앙통제센터에 보낸다. 이 정보를 분석하여 교통량, 사고유무, 사고위치 등을 파악하여 교통문제나 2차사고를 예방한다. 이 기술의 목적은 현재 상용화된 Global Positioning System(GPS)기술이 감지하기 힘든 환경이나 Vehicle to Vehicle(V2V)가 가지는 해킹의 문제점을 보안하여 안전한 운전환경을 제공하는데 있다.

Recently, automobile traffic systems are evolving toward Intelligent Traffic Systems(ITS) with smart sensor technology and collaboration between traffic systems and external ones. On the contrary, Korean ITS services have little improvement comparing with other communication services. The main causes of this phenomenon are due to already allocation of ITS recommended frequency band to broadcasting services, and also dedication of DSRC frequency band over ISM band resulting in interferences. This paper provides the analysis of current Korean ITS technology status, and two suggestions to activate the ITS industry. First, need to fix the ITS standard combining WAVE and DSRC specifications soon. Second, ITS frequency allocation to complete its standard implementation in near time frame.
