Transportation allocation requires information such as storage location and order information. In order to guarantee the safe transmission and real-time sharing of information in all links, an intelligent transportation control system based on blockchain technology is designed. Firstly, the technical architecture of intelligent transportation information traceability blockchain and the overall architecture of intelligent transportation control system were designed. Secondly, the transportation management demand module and storage demand management module were designed, and the control process of each module was given. Then, the type of intelligent transportation vehicle was defined, the objective function of intelligent transportation control was designed, and the objective function of intelligent transportation control was constructed. Finally, the intelligent transportation control was realized by genetic algorithm. It was found that when the transportation order volume was 50×103, and the CPU occupancy of the designed system was only 11.8%. The reliability attenuation of the code deletion scheme was lower, indicating better performance of the designed system.

The Korean high speed railroad is scheduled to open in 2004. For railroad-based integrated transfer system, it is essential to develop the intermodal information system for easy transfer to other travel modes. The understanding of mode choices by KTX passengers is crucial for the intermodal transportation planning. Recent development of Intelligent Transportation Systems(ITS) made it possible for railroad users to access the transportation information in a cabin or waiting areas at the station. Development of intermodal transportation information system will influence the relative demand for traveling by train from competing other transportation modes. The research is focused on a general overview of the ITS with an emphasis on intermodal transportation information system.

In this paper, we have recently created self-driving cars and self-parking systems in human-friendly cars that can provide high safety and high convenience functions by recognizing the internal and external situations of automobiles in real time by incorporating next-generation electronics, information communication, and function control technologies. And with the development of connected cars, the ITS (Intelligent Transportation Systems) market is expected to grow rapidly. Intelligent Transportation System (ITS) is an intelligent transportation system that incorporates technologies such as electronics, information, communication, and control into the transportation system, and aims to implement a next-generation transportation system suitable for the information society. By combining the technologies of connected cars and Internet of Things with software features and operating systems, future cars will serve as a service platform to connect the surrounding infrastructure on their own. This study creates a research methodology based on the Enhanced Security Model in Self-Driving Cars model. As for the types of attacks, Availability Attack, Man in the Middle Attack, Imperial Password Use, and Use Inclusive Access Control attack defense methodology are used. Along with the commercialization of 5G, various service models using advanced technologies such as autonomous vehicles, traffic information sharing systems using IoT, and AI-based mobility services are also appearing, and the growth of smart transportation is accelerating. Therefore, research was conducted to defend against hacking based on vulnerabilities of smart cars based on artificial intelligence blockchain.

기존 교통시스템의 운영 효율을 증진시키고 교통시설과 교통안전, 교통환경 개선을 동시에 충족시키는 지능형교통체계(ITS)도입을 위해 '99.2월에 교통체계효율화법을 제정하여 제도적 차원에서의 기반확대를 조성하였고, 지난 2000년 10월 대전광역시, 전주시, 제주시를 첨단교통모델도시로 선정하여 ITS 전국확산을 위한 교두보를 마련하였다. 국내에서 처음 시도된 첨단교통모델도시는 ITS의 수준을 한 단계 올렸고, 이를 통해 많은 관련 전문 인력의 양성과 경험이 축적이 된것으로 평가하고 있다. 따라서 지능형교통체계(ITS)와 관련하여 우리나라 3개 도시(대전광역시, 전주시, 제주시)에서 진행했던 지능형교통체계 구축사업의 특징과 추진과정 중의 시행착오 등을 파악하여 향후 국가ITS사업의 시사점을 도출하고자 한다. 총괄사업보고서 및 백서, 기본설계, 입찰안내서, 실시설계도서, 관리기관의 최종보고서 등을 분석하여 ITS사업의 기획에서 그 사업의 평가까지 일련의 단계를 통해 문제점과 향후 지자체 지능형교통체계사업의 발전방안을 논의하였다. 특히, 사업기간, 시스템 구성, 추진조직, 운영체계, 민간투자 및 평가체계와 함께 사업관리 등 발주방식에 대한 논의하였다.

Owing to the need to establish a cooperative-intelligent transport system (C-ITS) environment in the transportation sector locally and abroad, various research and development efforts such as high-tech road infrastructure, connection technology between road components, and traffic information systems are currently underway. However, the current central control center-oriented information collection and provision service structure and the insufficient road infrastructure limit the realization of the C-ITS, which requires a diversity of traffic information, real-time data, advanced traffic safety management, and transportation convenience services. In this study, a network construction method based on the existing received signal strength indicator (RSSI) selected as a comparison target, and the experimental target and the proposed intelligent edge network compared and analyzed. The result of the analysis showed that the data transmission rate in the intelligent edge network was 97.48%, the data transmission time was 215 ms, and the recovery time of network failure was 49,983 ms.
