Ideal Saturation Flow Rate and Geometric Adjustment Factors at Urban Signalized Intersection
도시부 신호교차로의 기본용량 및 기하구조 보정계수
Abstract
This research presets the method of determining basic capacity of signalized intersection using the concept of ideal saturation flow rate. Vehicle discharge rates during green time were collected and studied as part of the preparation of Korean Highway Capacity Manual. From the result of this study the ideal saturation flow rate and saturation queue position were determined. In addition, based on the ideal saturation flow rate two geometric adjustment factors(lane width and grade adjustment factors) were studied. The results were presented in this paper.
