Off-line signal timing plans is one of the most common traffic signal control plans currently. And the Green Conflict testing between two phases is the safe guarantee of the timing plans. This paper firstly introduces the concept of interim matrix to describe an easy executable way of Green Conflict testing and its application in signal timing software. Secondly, it also introduces a way of on-line speed survey method called Car Following Method(CFM) to collect timing parameter and evaluate the effect of timing plans. The paper offers a simple and applied method for traffic engineer to design, evaluate and optimize signal timing plans.
