The signal intersection analysis method in the Korea Highway Capacity Manual is far more complicated than other facility analysis methods and requires a variety of variables, so it has difficulty in situation surveys and analyses compared to other tools such as T7F. Due to this problem, the Korea Highway Capacity Manual is low in use frequency, and actual analysis is performed by inputting only traffic volumes and signal operation types.
A total of 32 input parameters by movement is set as a basic condition, and the change amount in delays between the minimum and maximum values of other variables is reviewed to analyze its sensitivity. The effects on the left turn, straight and right turn transportation differ depending on the kind of input variables, so the range of analysis results varies depending on the characteristics of relevant variables.
