Abstract

This paper develops a decentralized advanced traveler information system (ATIS) under the connected vehicle environment, recently regarded as one of most promising tools in Intelligent Transportation Systems (ITS). The performance of the proposed ATIS is reinforced by introducing autonomous automatic incident detection (AAID) function. The proposed ATIS is implemented and tested using an off-the-shelf microscopic simulation model (VISSIM) on a simple traffic network under idealized communication conditions. A key attribute of this experiment is the inclusion of a non-recurrent traffic state (i.e., traffic incident). Simulation results indicate that the ATIS using V2V communication is efficient in saving drivers' travel time and AAID plays an important role in improving the effectiveness of the system.

본 논문은 최근 지능형교통시스템에서 중요한 수단으로 간주되고 있는 차량 간 통신을 이용한 분산식 첨단 교통정보시스템을 개발하고자 한다. 또한 독립자동유고감지 기능을 통해서 제안된 첨단 교통정보시스템의 효과를 개선하고자 한다. 이상적인 통신 환경을 가정한 단순화된 교통네트워크에서 미시적 시뮬레이션 모델인 VISSIM을 통해 제안된 첨단 교통정보시스템을 구현하였으며 특히 비반복적으로 일어나는 교통상황(예를 들면, 교통사고)을 사용하여 모델의 효과를 관찰하였다. 결론적으로 본 연구에서는 차량 간 통신을 통한 첨단 교통정보시스템의 효율성을 확인함과 동시에 독립자동 유고감지 기능이 시스템의 성능을 향상시키는 것을 보여주고 있다.
