For freeway merge areas, ramp metering used to be considered a panacea to increase capacity and minimize the conflict of the area. Because of the absolute priority of freeway mainline, however, the vehicles on ramp have a hard joining the traffic flow on the mainline when the volume of the freeway is very high. Therefore, the driver on the ramp may be compelled to merge and then this type of behavior disturbs the freeway traffic, and it can even bring about freeway disorder and congestion. In order to conquer this problem, this paper puts forward a new method to alternate the right of way between the two conflicting traffic flows. By signal control, like multi-phase signal intersection, mutual disturbances can be eliminated. Likewise, it can enhance traffic safety and dynamically adapt to the traffic demand of a merge area in comparison to the conventional ramp metering.
