延迟更新 meaning in English
deferred update
delayed updating
Examples
- Based on these models , a main - road traffic flow model with two speeds on one dimension is designed . this model simulate the situation of one road in the city , traffic lights placed on the crossing , using the computer simulation , firstly , in the case of synchronized traffic lights , we investigated the velocity and flow of the model when the initial density , the turning probabilities , the number of the traffic lights , the green to signal ratio and the period of the signal are changed , then we have advanced some meliorate measure to traffic flow ; secondly , in the case of the traffic lights " signal update delay in turn , we found the optimal matching between the period of the signal and the delay time of the traffic lights so as to the perfect velocity and the flow of the model are attained
在此基础上，建立了一维二速主干道模型，该模型模拟了城市交通中一条主干道的交通情况，在交叉口处设置红绿灯，通过计算机模拟，首先，在交通灯信号同步更新的条件下，研究模型在改变车辆的初始密度、转向概率、交通灯个数、红绿灯信号的绿信比、红绿灯信号周期等各种情况下主干道的速度、流量的变化，根据模拟结果提出一些改善交通的有效措施；其次，在交通灯信号依次延迟更新的条件下，研究模型在参数道路长、红绿灯绿信比、交通灯个数、车辆的初始密度给定的情况下找到红绿灯信号周期和延迟时间的最佳匹配使得主干道的速度、流量达到最理想的值。
