Abstract

Convoy driving is one of the technologies of multi-vehicle cooperation driving along with platoon driving. All over the world, research on vehicle control mechanisms to maintain vehicle formation during convoy driving convoy driving has been actively conducted and in Europe's Autonet 2030 project has developed and demonstrated convoy driving services for highways. But, even the concept of convoy driving is still insufficient in Korea. Therefore, in this study, the concept of convoy driving service was established and scenarios and communication messages for service application on urban roads were developed. And its effectiveness was verified through simulation analysis. As a result of comparing and analyzing individual vehicle cooperative driving and convoy driving for the blind spot support service and dilemma zone safety support service, which are representative V2I cooperative driving services on urban roads, the number of conflicts(indicator of traffic safety) and delays and stops(indicator of traffic efficiency) are significantly improved in convoy driving compared to individual vehicle cooperative driving.

호송주행(convoy driving)은 군집주행(Platoon)과 함께 다중차량 협력주행 (Multi-vehicle cooperation) 기술 중 하나로써 국외에서는 호송주행시 차량의 대형유지를 위한 차량제어 메커니즘 연구가 활발히 진행되고 있으며, 유럽의 Autonet 2030연구에서는 고속도로를 대상으로 호송주행 서비스를 개발하고 실증한 바 있으나 국내에서는 아직까지 호송주행에 대한 개념정립조차 미흡한 실정이다. 이에 본 연구에서는 호송주행의 서비스 개념을 정립하고 도시부 도로에서의 서비스 적용을 위한 시나리오 및 통신 메시지 등을 개발하여 시뮬레이션 분석을 통해 그 실효성을 검증하고자 하였다. 도시부 도로의 대표적인 V2I 협력주행 서비스인 사각지대 운행지원 서비스 및 딜레마존 안전주행 서비스를 대상으로 개별차량 협력주행 시와 호송주행 시를 비교 분석한 결과 교통안전성 지표인 상충횟수와 교통효율성 지표인 지체시간 및 정지수가 개별차량 협력주행 시보다 호송주행 시 크게 개선되는 것을 알 수 있었다.
