Abstract

C-ITS is an intelligent transportation system that can improve transportation convenience and traffic safety by collecting, managing, and providing traffic information between components such as vehicles, road infrastructure, drivers, and pedestrians. In Korea, road infrastructure is being built across the country through the C-ITS project, and various services such as real-time traffic information provision and bus operation management are provided. However, the current state-of-the-art road infrastructure and information linkage system are insufficient to build C-ITS. In this paper, considering the continuity of time in various spatial aspects, we proposed a group-type network-based traffic situation recognition system that can recognize traffic flows and unexpected accidents through information linkage between traffic infrastructures. It is expected that the proposed system can primarily respond to accident detection and warning in the field, and can be utilized as more diverse traffic information services through information linkage with other systems.

C-ITS는 차량, 도로 인프라, 운전자, 보행자 등 구성요소 간 교통정보를 수집·관리·제공함으로써 교통 이용 편의, 교통안전을 제고 할 수 있는 지능형교통시스템이다. 국내에서는 C-ITS 사업을 통해 도로인프라가 국내 전역에 구축되고, 실시간 교통정보 제공, 버스운행 관리 등 다양한 서비스가 제공되고 있다. 그러나 현재 도로상황 인지·전파 등을 통한 교통안전 중심의 C-ITS를 구축하기에는 첨단도로 인프라 및 정보 연계 체계가 미흡한 실정이다. 본 논문에서는 다양한 공간적 측면에서 시간의 연속성을 고려하여, 교통 인프라 간 정보 연계를 통해 교통흐름과 돌발 사고를 인지할 수 있는 그룹형 Zigbee Mesh 네트워크 기반 교통상황인지 시스템을 제시하였다. 제안하는 시스템은 1차적으로 현장에서 사고감지 및 경보 등의 대응이 가능하며, 타 시스템과의 정보 연계를 통해 보다 다양한 교통정보 서비스로의 활용이 가능할 것으로 기대한다.
