In this paper, a coordinated signal control based on pattern selection was chosen as the subject of the research and the relationship between control efficiency and frequency switching control pattern according to traffic fluctuation was studied. The switching policy was optimized by using DP, and total delay as a criterion was evaluated through time-scanning simulation. From some computational examples, it was found that switching control that is responsive to traffic demand improves control efficiency. However, it was also found that the avoidance of excessive switching was better except for remarkable traffic fluctuation because the reverse effect by the excessiveness was recognized.
