This study developed a new method of calculating air pollution on the traffic road. Usually these kinds of mettods have calculated the state of pollution on the road or its neighborhood by regarding the traffic road as linear continuous source or rectangular column one. Also regarded the pollution media diffused by natural air in the intersecting direction. Therefore these methods had a fault that the solution for air pollution in windless was to infinity. In this study that fault is removed. Then this study tries to calculate the diffusing state regarding each car as moving point source. For this end new two notions "Model of wake" and "Model of Equal space in pollution" are introduced. "Model of wake" is used to caluclate the pollution backword when one car ran. "Model of Equal space" is used to calculate the pollution around the road when cars ran in equal space line. This is calculated for additioning each car's pollution in "Model of wake". In this study Bosanquet-Peason system is used to calculate "Model of wake" because his system is good for no dimention. For the reason mentioned above this method in this study can calculate the pollution around the road in windless. Of cource it can when it is blowing. By way of example the solutions are given in the case of windless and 1m/s, 5m/s and 7m/s in the intersecting direction. On the other hand pollution around the road was measured. For examinating propriety of this method these measured values are contrasted with thoretical ones.
