고속도로 용량과 속도 분석을 통한 최적 교통량 추정에 관한 연구

Abstract

Highways have become very congested especially during the holidays. In addition, traffic demand is great at a certain time. To manage traffic flow, Korea Highway Corporation uses tollgate controlled metering method that restricts the flow entering the highways around the crowded areas. Since measuring the slow-down length of a highway is used as a current standard of the regulation, it can't solve problems or provide an optimal standard of the regulation when traffic congestion is aggravated. Therefore, this study suggests an estimation method of optimal traffic volume in the sections of highway lines and an application method of a tollgate controlled method by analyzing highway capacity and speed. The summary of the study is followed. First, we find major held-up sections using Speed-Flow Diagram in the sections of highway lines. Second, the best capacity of them is estimated with MMRC Model. Last, we propose a new standard of the regulation by applying the estimated volume. With the optimal amount of traffic applied, the study expects to prevent the traffic congestion as well as control traffic flow more effectively.
