Abstract
Traffic congestion is becoming a serious urban problem in Pusan area, where is suffering from the severe traffic congestion because of the incoming and outgoing traffic regardless of the peak periods. In addition, traffic congestion is getting more serious on the arterials because of the insufficient transportation facilities and the inappropriate transportation systems with increased traffic. Thus, the purpose of this study is to identify the real-time cycle-based traffic characteristics, compare and analyze the real-time cycle-based transportation systems before/after the optimal settings and before/after the optimal phase settings, and finally suggest the validity of the real-time cycle-based optimal phase settings on the pre-timed 4-leg signalized intersections of the arterials in Pusan area.


From the above transportation system analyses based upon the real-time cycle-based traffic characteristics on the pre-timed 4-leg signalized intersections, the following results were obtained:


i) The real-time cycle-based transportation system analyses were thought to be more efficient than the existing hour-based ones, because the typical peak characteristics were not found on the pre-timed 4-leg signalized intersections under study.


ii) Delay from the real-time cycle-based transportation system analyses was shown to increase by 20 percentage or more on the pre-timed 4-leg signalized intersections under study, when compared with delay from the existing hour-based delay analyses.


iii) Delay after the real-time cycle-based optimization was shown to reduce by 20 percentage or more on the pre-timed 4-leg signalized intersections under study, when compared with delay before the real-time cycle-based optimization.


iv) Delay after the real-time cycle-based phase optimization was shown to reduce by 30 percentage or more on the pre-timed 4-leg signalized intersections under study, when compared with delay before the real-time cycle-based phase optimization.
