Abstract

In Korea, interest in truck platooning is increasing because most cargo transportation is done by road. Truck platooning is the operation of two or more trucks in a row to form one platoon, which can increase road capacity and improve fuel efficiency. In this study, to analyze the effect of truck platooning on traffic flow, scenarios were created according to traffic conditions and truck platooning operating conditions. In order to understand the effect of the truck platooning operating conditions, correlation analysis was conducted with the average travel speed, the number of lane change disturbance, and the number of disturbance in the entry/exit section. As a result, the number of trucks in the platoon, the spacing of trucks in the platoon, and the spacing between platoons were found to have an effect on the average speed and the number of lane change disturbance In addition, the truck platooning ratio was found to have a strong correlation with the average travel speed and the number of lane change disturbance regardless of the LOS.

우리나라는 대부분의 화물 운송이 도로를 이용하여 이루어지기 때문에 화물차 군집주행에 관한 관심이 증가하고 있다. 화물차 군집주행은 연속된 두 대 이상의 화물차들이 하나의 군집을 구성해 주행하는 것으로 도로 용량의 증가와 연비를 개선할 수 있다. 본 연구에서는 화물차 군집주행이 교통류에 미치는 영향을 분석하기 위해 교통 조건, 화물차 군집주행 운영 조건에 따른 시나리오를 생성하였다. 화물차 군집주행 운영 조건의 영향이 미치는 영향을 파악하고자 평균통행속도, 차로변경방해건수, 진출입구간방해건수와 상관분석을 실시하여 결과를 도출하였다. 군집 내 화물차 수, 군집 내 화물차 간격, 군집 간 간격은 평균통행속도와 차로변경방해 건수에 영향을 미치는 것으로 나타났으며, 군집주행 화물차 비율이 LOS와 무관하게 평균통행 속도와 차로변경방해건수에 강한 연관성을 가지는 것으로 나타났다.
