The invention discloses an in-transit amount calculation method based on checkpoint fusion. The method comprises the following steps of: 1, carrying out algorithm initialization, specifically, settingdifferent model parameters for each type of rtic road, carrying out the real-time calculation of a speed in-transit amount, calculating the in-transit amount of each rtic road in real time accordingto the speed, carrying out checkpoint verification, for the checkpoint data with good quality, calculating an in-transit amount according to the flow, then comparing the in-transit amount with the in-transit amount calculated based on the speed, checking other similar rtic, and then outputting a result; 2, carrying out algorithm implementation, specifically, firstly obtaining blocking density, adjusting parameters when the speed is too high according to equations that FastSpeed=0.6, and Speed Discount=0.7, the parameters represent that if the speed is larger than 60% of the free flow speed, the calculation result of the in-transit amount is multiplied by 0.7; and step 3, carrying out range calculation, specifically, calculating the in-transit amount of a single RTIC based on the speed. According to the method of the invention, in-transit amount data can be better obtained, traffic police personnel can be distributed according to the in-transit amount, and the road traffic capacity canbe evaluated.

    本发明公开了一种基于卡口融合的在途量计算方法,包括以下步骤:步骤一:进行算法初始化:对每个类别的rtic道路设置不同的模型参数,之后进行实时计算速度在途量,根据速度,实时计算每个rtic的在途量,最后进行卡口校核,对于质量好的卡口数据,根据流量计算在途量,然后与用速度计算的在途量进行比较,然后对其他同类的rtic进行校核然后输出结果;步骤二:进行算法实施先获取阻塞密度,在速度过快时调整参数,FastSpeed=0.6,SpeedDiscount=0.7,上述参数表示,如果速度大于自由流速度的60%时,在途量计算的结果将乘以0.7;步骤三:计算范围,基于速度先获取单RTIC在途量计算。本发明能够更好的获取到在途量数据并根据在途量进行交警人员分配并进行道路通行能力评估。
