Abstract

Recently, there has been a worldwide increase in research and development on automated vehicles for commercialization. It is expected that the use of level 3 autonomous vehicles on continuous-flow roads will be introduced and will increase. Consequently, various studies have been conducted to investigate the impact of mixed traffic flow with automated vehicles based on the market penetration rate (MPR). However, these studies have been conducted independently, and the results have shown different trends. Therefore, this study attempted a quantitative analysis of the impact of automated vehicles on mixed traffic flow on uninterrupted roads through a meta-analysis. The results showed that the effect size estimated from an MPR of 75% or higher was statistically significant.

최근 국내외에서 자율주행자동차의 상용화를 위한 연구개발이 활발히 진행중이며, 연속류 도로에서 레벨3 수준의 자율주행자동차들의 주행이 도입 및 증가될 것으로 예상된다. 이에 다양한 국내외 연구들에서 자율주행자동차의 시장점유율(MPR)에 따른 혼재 교통류 연구들이 진행되었으나, 각 연구들은 독립적으로 시행되어, 연구 결과에 따라 서로 다른 경향을 보인다. 이에 본 연구에서는 다수의 연구 결과들을 계량적으로 취합하여 통합된 결론을 내리는 메타분석 기법을 이용하여 연속류 도로에서 자율주행자동차의 혼재교통류의 영향을 분석하고자 하였다. 분석결과, 혼재율 75% 이상부터 추정된 효과크기가 통계적으로 유의미한 것으로 나타났으며, 자율주행자동차 혼재기에 연속류 도로 운영 및 관리를 위해서는 자율차 혼재기별 맞춤형 정책이 필요할 것으로 판단된다.
