This paper proposes two systems, Driving Security Determination and Assistance Overtaking System and Intelligent System, to analyze the performance of the right-most rule on multi-lane traffic flow. Driving Security Determination and Assistance Overtaking System (DSDAOS) is established to analyze the relationship between security, speed limit and traffic flow while Intelligent System (IS) is theoretically designed on the basis of DSDAOS and it has better impact on promoting traffic flow from aspects of speed limit and lane conditions when compared to DSDAOS. DSDAOS is a system that utilizes computer to produce vehicles in the simulation, give some properties to them which are made to run in lanes according to certain rules, and finally output security level and relational traffic flow. IS is a system in which computers use information-gathering device to automatically gather information, then deal with the information and get relating response which refers to the function of shifting speed limit of lanes and changing lanes to promote traffic flow. All in all, IS makes great difference to promote use ratio and carrying capacity of lanes. What is more important is that Intelligent System is a circulating system with high independence.
