Fee collection control method for ensuring traffic quality of specific lane

The invention relates to a fee collection control method for ensuring the traffic quality of a specific lane. The method comprises the steps of defining the update period of a lane fee collection standard as N days, and keeping the lane fee collection standard within one period to be unchanged; according to the traffic congestion degree, formulating an initial lane fee collection standard, whereinthe fee collection is xp for each duration of t0 during the peak period, and the fee collection is xf for each duration of t0 during the mean peak period; calculating the lane saturation degrees of aplurality of time periods during the peak period is calculated by utilizing bayonet data, figuring out the average value of all the saturation degrees, and recording the average value as the lane saturation degree of the peak period; defining the target value of the lane saturation degree to be a maximum saturation degree of the lane traffic flow under the free-flow state. A difference value Epsilon p is adopted as an eva
