영문 초록

This research is to decide Platoon Dispersion Factor(PDF)^* in a progression analysis among diverse inner variables of T7F model and to analyze the sensitivity of Performance Index and Platoon Index which is the factor of an effectiveness evaluation by means of changing PDF through the progressive signal simulation. The PDF of an example site is 0.28∼0.33. The value in upstream is still lower than that in downstream on the same intersection. According as the value of a Platoon Index by PDF`s changes increases each 0.1, it largely decreases average 5.0%. In other words, PDF`s changes have a sensitive effect on the value of a Platoon Index^(**). But, a Performance Index by PDF`s changes remains hardly ever changed. Its average maximum and minimum values range from 82.93 to 82.5. The deviation between the two average values is 0.5%. In conclusion, though PDF fixes 0.34 in intersections progression, it has little effect on deciding a Performance Index^(***). The value of a Platoon Index ranges from 0 to 2. It is analyzed that the nearer the value converges 2, the more effective progression efficiency is.
