Abstract
Traffic signal controllers plays a key role in control and prevention of traffic optical units. Most notably, installation of new traffic controller technology that calculates signal control parameters such as Cycle length, Split and Offset in real time based on traffic volume counted by traffic detector is actively promoted. However, this type controller wasn’t actually popularized by its h igh cost. On the other hand, a traditional traffic controller remains general used which controls optical units in accordance with the pattern table that combines signal control parameters for a long time. At this moment, this traditional type continues to use signal control parameters at time that traffic signals were installed. In this paper, an management support system which fits in the pattern table of signal control parameters with the traffic flow was proposed using probe information and proved this feasibility.
